Chapter 191 - Investigation

One week later...

Hilde and Brad came to the governmental affairs office to report on

how things had turned out. For some reason, Merula was also with them.

The quarantine period had ended for those involved at this point.

People had been investigating Gerula's route in the meantime, but there

were no new infections in the country. Even Gonzales, who had clearly had

contact with him, was fine. This all seemed to indicate that this disease

really didn't pass from person to person.

Liscia and Hakuya joined up shortly, then Hilde first explained how

Gerula had died, and how Brad had performed an autopsy in accordance

with his will. While it had been at his request and signed off on by the Spirit

Kingdom King, it still felt...awful.

Unable to bear the silence, I asked, "His death wasn't in vain, right?"

Hilde nodded. "Of course not. We learned many things from his body.

Including how pernicious this disease is."

"Well...that's good then. And what of his body?"

"We secured the samples we needed, and I embalmed him," Brad

answered. "Externally, it should be in good condition. I'd like you to return

it to the bereaved."

"It's an infected corpse, right? Don't we need to cremate it?"

"This isn't the kind of disease where someone could get the infection

from a cadaver. It shouldn't be a problem."

"Oh, yeah? Did you find something out then?"

Hilde and Brad both nodded with pensive looks on their faces.

"Between how Sir Gerula had described his symptoms to us and what

Brad found from investigating his body, there were discrepancies in our

findings. Simply put, what Sir Gerula felt and was actually happening

didn't always match."

"What does that mean exactly?"

"This disease has many symptoms, but..." Hilde started, flipping

through some papers she was holding.

Probably clinical records.

"Ah! Here's an example," she continued. "He said he was itching or

had stabbing pains in his skin. If you went purely by what he told me, I

would have assumed it was some kind of toxic reaction."

"Wait, like he'd been poisoned?"

It isn't a disease? If this is because of a monster's poison, that would

explain why it only affected warriors...

"No, we can't say that for certain. In my investigation, I found nothing

wrong with his skin. It was the organs that had taken the real damage. I feel

like the symptoms are close to those of a parasitic infestation," Brad added.

Hilde nodded. "In the interview, it seemed like poisoning of some sort.

When we examined the body, it looked more like a parasitic infestation.

That being the case, we should assume both were happening at the same

time. The parasites inside his body were releasing some kind of poison."

"Which means...what we need isn't an antidote, but a deworming

medicine. If we don't deal with the parasites, we can't solve the

fundamental problem," I said, but Brad shook his head.

"A dewormer isn't going to cut it. That only works when the bugs are

in the digestive organs anyway. Unfortunately, I didn't find any there."

"Huh? Where were they, then?"

"That's what we brought Merula here to explain," Hilde said, ushering

her forward.

"Sir Souma. You asked Genia to investigate magicium, right? I know

because I was there at the time."

"Ah, yes, that's true."

When the possibility arose that magicium was nanomachines, I had

asked Genia and Merula to prioritize researching curse ore, which might be

a mass of them.

"Healing magic is the work of nanomachines inside the body. When I

heard that idea, I had questions, and Genia and I talked about it. If the

magicium or nanomachines is inside the body, where is it?"

"Where?"

"I think that the smaller they are, the less impactful they can be. In

order for something small to exert a large power, it would take a large

number of them gathering together. In order to heal wounds, the magicium

in the body would need to be gathered quickly. In other words, there needs

to be some kind of large path. And if we're talking about pathways laid out

across the entire body..."

Merula slapped her hand down on a diagram of the human body she

had prepared.

"The blood vessels. Magicium is flowing through our blood. That's my

and Genia's idea."

"I see..."

Nanomachines circulate through the body in the bloodstream, huh?

Depending on how you look at it, the idea of a foreign object like

nanomachines in your bloodstream could be chilling, but if this world was

in the far future, maybe it was possible.

Merula continued, "And now we have this disease, the Spirit King's

Curse. It makes the infected unable to use magic, and causes healing magic

to no longer work on them. This could be seen as having an effect on the

magicium in their body. And we believe that magicium is in the

bloodstream."

"So, basically, the bugs are in their blood," Hilde concluded, pulling out

two little bottles containing dark red liquid. "One is Sir Gerula's blood,

violated by the Spirit King's Curse. The other is Madam Merula's healthy

blood. With my third eye, I was able to see bugs squirming around."

Bugs in the blood... Ah!

"Like blood flukes or rat lungworms!"

"What are those?" Liscia asked.

"They caused endemic diseases in the world I came from. The parasites

entered the body through the skin, lived and bred in the blood vessels,

eventually eating away at their host until the person died... It's a horrible

disease. There are definitely parasites that can live in the blood vessels."

Merula nodded at my explanation. "I don't know the specific case

you're talking about, but if you say that bugs in the blood could be affecting

magicium, I can understand how that might cause poisoning symptoms. If

magicium is so small even the three-eyed race can't see it, then we don't

know what it's made of. And if they lose their proper function and become

foreign bodies floating through the body..."

"That can't be good for us, yeah."

I was kind of convinced. I didn't know what the nanomachines would

be made of, but if it was metal, leaving it to float through the body could

cause a toxic reaction.

There's a history of cadmium causing itai-itai disease, and organic

mercury causing Minamata disease too... It was still vague, but we were

starting to see the full picture of the Spirit King's Curse here. No, wait...

"If you knew what the parasites were, couldn't you treat them, Hilde?"

I seemed to recall that if we knew what the nature of the parasites was

and the damage they were doing, it was supposed to be possible to treat

them with light magic. And she might be targeted by theocracies as a result.

Ever since I'd received that report, I had given the light mages who

wanted to become doctors in our country medical training, and worked to

increase the number of people who could do the same things as Hilde.

While it was still secret, their numbers were steadily rising.

Hilde shook her head in disappointment. "Even with my magic, I

couldn't treat Gerula."

"It seems most likely that Madam Hilde's magic uses the magicium

inside the body to eliminate parasites. Once that magicium has been

rendered inactive by the bugs...I think there's nothing left that we can do,"

Merula explained.

"I see..."

It was too late for Gerula, then, huh? No... But still...

"If they still have limited symptoms, couldn't we save them? If the

magicium in their body still works, couldn't it be used to eliminate the

parasites?"

"Yes. It's possible," Merula agreed with my speculation.

Gerula's death wasn't in vain by any stretch. I felt like we were seeing

the light at the end of the tunnel now.

"So, Your Majesty!" Hilde suddenly moved up real close to me. "In

order to confirm that, would you let us go where the patients are?"

Seeing how serious she was, I scratched my head.

I understood how she felt, and I saw the necessity. When I consider the

risk of anything happening to the two of them, I can't give my assent so

easily.

"We understand how you feel, but we cannot allow that," Hakuya said

as I was thinking about it. "You are the two leaders of the Kingdom's

medical world. It would be a great loss if anything were to happen to either

of you. What if there was an outbreak here while you were away? You

wouldn't be able to treat it, Madam Hilde."

Hilde was quick with a retort.

"That will be fine. One of the king's key policies has been to increase

the number of people who can cure parasitic diseases with light magic the

way I can. I'll explain everything about these bugs before I go, so even if

there is an outbreak here, they should be able to treat it."

"But—"

"No, in this case, I think we should do as Hilde says," I said, cutting off

Hakuya, now that I had my thoughts sorted out.

Hakuya stared into my eyes.

"Are you sure that's all right, sire?"

"With a disease like this, our first steps will be crucial. We couldn't be

careless before we knew the nature of it, but now Hilde and the others have

figured it out. If we know what we're up against, we should deploy

everything we have and try to wrap things up as soon as possible."

If you mess up the initial response, you'll constantly be on the back

foot. That was something the history of my past world had taught me.

Hilde and Brad nodded firmly.

"The king's got it right," Hilde said. "Time's our enemy in the fight

against a disease like this."

"Yeah," Brad agreed. "Fortunately, now that we know what type of

disease it is, we can keep the people treating it safe. Black-robed Prime

Minister... Could you leave this to Hilde and I?"

At this, Hakuya finally gave in and nodded.

"I understand. I lack the knowledge to handle medical issues to begin

with, so I will defer to your and His Majesty's opinions."

"Sorry, Hakuya. You had to make the objection because I was slow to

decide," I confided.

"Don't worry about it. That's the prime minister's job."

And so, it was decided that Hilde and Brad would go to the site. Once

they were prepared, I'd send them first to the port city that Fuuga had given

us, and then have him help get them to the Father Island.

"The question is who to send with them..."

"Don't tell me you're planning to go too, Souma?" Liscia asked,

looking incredibly worried.

In order to wipe away her concerns, I put my hands on her shoulders

and silently shook my head.

"No, I can't go with them right now. It would let me make political

decisions on the spot if they become necessary, but...I think there's other

stuff I'll need to be doing. Things only I can do, probably."

"Really?"

"Yeah. But, like I was saying, I want to send our best team. So, for a

start, I want Tomoe, Ichiha, and Yuriga there."

"Tomoe..." she gasped, shocked. "You're sending the children?! Isn't it

way too dangerous?!"

With a stern expression, I nodded and said, "Yeah. I know it's

dangerous. But... Hilde, since this disease only affects warriors, you

theorized that it came from the monsters they fought, right?"

When I turned the question to her, Hilde nodded.

"Huh? Oh, yes, that's right. When you consider that the parasites live in

their blood, I think that contact with monster blood is what causes the

infection. It's possible that the parasites entered through their skin after all

the spatter from slashing and stabbing monsters got on their bodies."

"In that case, to prevent the spread of the infection, we'll want to know

what monsters—no, if we think using the MPI system, it might be better to

ask 'the monsters with what part.' We need to figure out the answer

immediately. To that end, Ichiha's knowledge as a monster specialist, along

with Tomoe's ability, will be effective tools."

"I get that, but...why Yuriga?" Liscia asked.

"We're sending them to Fuuga's territory, after all," I said, scratching

my head. "If his little sister is around, that should keep his people in check.

Even if some of the men are uncooperative because they look down on the

kids, she'll be able to keep them in line. And if the opposite happens—like

if someone who understands Ichiha's value tries to kidnap him—they won't

be able to take drastic measures that would risk angering Yuriga."

"I see... So you've thought this through..." Liscia seemed to understand

it intellectually, but was still worried.

"I'll send bodyguards for the kids too, of course... Hakuya."

"Yes."

"I'm sure there's going to be the need for someone to make political

decisions over there. Would you go, and chaperone the kids while you're at

it?"

Hakuya seemed a little surprised when I asked that.

"Me?"

"I'm uneasy about sending my prime minister to the site of an

epidemic, but could I ask you to handle it?"

"If that is your command, sire. It's certainly true that if one of us goes

to the site, we can avoid any delays in decision making. However, you were

just saying there are things you'll need to do. Is it all right for me to be

away from the castle?"

"Yeah, that won't be a problem. Er, well... It'd be reassuring to have

you here, but I can use Julius as a sounding board too. Let's have everyone

do what they're best suited for."

"Very well. I'll accept the job."

Good. The team's been decided then.

"Well then. Hilde, Brad, and the team of doctors made up of their

apprentices will be going to the port city on the west coast together with

Prime Minister Hakuya and the three kids, Tomoe, Ichiha, and Yuriga.

Inugami and some other Black Cats will be going as bodyguards too. Oh!

What about Hilde and Brad's daughter? Do you want us to take care of her

here at the castle?"

Hilde and Brad looked at one another before shaking their heads.

"There's no telling when we'll be able to come back. We'll take Ludia

with us, I think," Hilde said.

"If we take the right precautions, we can minimize the risk of infection,

after all," Brad agreed.

Looks like they'll be taking her along. Ludia was about a year older

than Cian and Kazuha. They'd probably be worried about leaving her with

us too long. If that was their decision, I was fine with it.

Now, with all this hashed out... It's time for those of us staying behind

here to get to work.

"Liscia. Send an emergency messenger to Julius and have him report to

the castle for duty."

"At the house of the Lastanian royal family, right? I'll get that done."

"And Hakuya, before you go, contact Kuu in the Republic and Shabon

in the Archipelago Union to set up a broadcast meeting."

"Understood."

Okay, that was our general policy more or less set. I rose and said, "All

right, everybody, let's give this everything we've got."

"""Yeah!"""

◇ ◇ ◇

Roughly another week later...

Whoosh... Rattle... Woosh... Rattle...

"It's the sea..."

"It sure is..."

Tomoe and Yuriga were standing together on the pier in the port town

given by the Great Tiger Kingdom. They could hear the sound of the waves,

and small boats moored nearby shaking as they rose and fell on them.

Yuriga spread her wings and flapped them.

"I like looking at the sea, but I hate the sea breeze. I felt the same way

in the Nine-Headed Dragon Archipelago too. My wings feel all sticky."

"Jeez, Yuriga. We're not here to play around, you know?"

"Yeah, I know... So, where's Ichiha gone?"

"Gathering information on the monsters with Mr. Hakuya. They say

they want to find out what monster's causing this. They're hoping to have

some ideas before we go to the Father Island."

Yuriga grinned at Tomoe's explanation. "Well, your ability isn't so

useful until we go where the monsters actually are, huh?"

"Murgh... You say that, but you've got nothing to do either."

"I'm doing my job just by standing right here. It's what your brother

asked me to do."

Before their departure, Souma called Yuriga aside and asked her to

keep a keen eye on Tomoe and Ichiha and protect them to make sure that

none of Fuuga's men mistreated them. At the time, she'd asked, "So, um...

If anything does happen to them, what will happen to me?"

"Well...if anything does, I won't be able to let you stay in this country

anymore. We might get into a head-on confrontation with Fuuga's country

over it, after all."

"Y-You'd go that far..."

"Well, I'm trusting it won't come to that though," Souma replied curtly.

His eyes didn't give off the usual laid-back impression. They were the

eyes of a king who wouldn't hesitate to let his power do the talking. Yuriga

understood quite well how much he cared for his family, and just how much

laying a hand on any of them would enrage him.

"R-Right! Obviously, I'll look after them for you. I still want to learn

here, and I don't want to be chased out either."

That answer had made Souma mellow out.

With a slight bow to Yuriga, who was younger than him, and a lower

social stature, he said, "Please take care of them."

Yuriga sighed as she remembered this.

I still want to stay in his country, huh? Just how long will all this be

able to last?

She wasn't as good a student as Ichiha or Tomoe, but Yuriga was

cleverer than her years showed, and knew exactly what position she was in.

She'd likely be able to stay with them until she graduated from the

academy. But what about after that? What would happen to her then?

Yuriga was one of Fuuga's few relatives. As the younger sister of a

king, it was easy to see she'd be used in a political marriage. That was a

given for the royal families of this world, and Yuriga agreed it was only

natural. But...she had to wonder where she'd be married off to. Who Fuuga

saw as his enemies and allies would likely change that.

Yuriga glanced at Tomoe.

This girl would no doubt be putting down roots in the Kingdom of

Friedonia. Based on the way she was acting lately, she might take Ichiha as

her husband. Lucy and Velza would likely live in this country too.

When the time comes, where will I be, and who will I be with? When

she thought about it, frustration welled up inside her. What am I even

thinking about...?

If she'd just blurt it all out, maybe it would be easier for her. But she

couldn't tell Tomoe. Their positions were too different, and moreover...it

just rubbed her the wrong way.

If I'm looking for someone in a similar position... Oh! Suddenly,

someone flashed through Yuriga's mind. A lovely lady who had married the

current king for political reasons, but still shone brilliantly even now.

Tomoe's adopted big sister. When we get back...I think I'll talk to her about

it...

Suddenly, a voice called out, "Ship's coming!"

Looking out to sea, Yuriga could see the sails.

"They're here, Yuriga."

"I know. We're going to go greet them."

The two of them hadn't just been killing time at the pier. Today, the first

batch of patients from the Father Island was arriving, and they had been

tasked with greeting them.

"They're all people with relatively light symptoms, right?" Tomoe

asked and Yuriga nodded.

"Yes. And those in positions of leadership in the military. Without

them, their units won't function, so..."

As the large ship arrived, Yuriga thought, Sir Shuukin must be on this

ship.

The ship landed, and Tomoe and Yuriga rushed to its side. The "cargo"

was already being unloaded. Stretchers with four handles were being

lowered from the side of the ship by rope.

"We've got sick men on there! Easy does it!" an energetic young

woman shouted up above.

Tomoe and Yuriga looked up to see a beautiful woman with clear white

skin and pointy ears standing there.

"An elf?" Tomoe wondered.

"Must be one of those high elves from the Spirit Kingdom, right?"

Yuriga replied.

As the two were talking, the elf woman jumped down from the ship.

Despite the height, she landed agilely and stood in front of the two

surprised girls.

"Children? We're unloading the patients, so you should stay a—

wait...you have wings."

The elf woman's eyes widened. Yuriga was miffed about being treated

like a child, putting her hands on her hips and puffing out her chest.

"I am Yuriga, younger sister of Great Tiger King Fuuga. And this is

Tomoe, adopted sister of King Souma of Friedonia."

"H-Hi," Tomoe stammered with an awkward smile.

The elf woman reacted with surprise and hurriedly bowed. "Ah! I-I

apologize! I am Elulu, daughter of Spirit Kingdom King Garula! I

apologize for treating you so rudely when I didn't know you were foreign

princesses!"

"Um, it's okay... You don't have to be so polite. You're a princess too,

Ms. Elulu," Tomoe said. She wasn't fond of being treated so reverently.

"R-Really?" Elulu raised her head.

Yuriga's anger seemed to have subsided by this point, and she asked,

"So, Madam Elulu. Is Sir Shuukin aboard this ship?"

"Huh? Oh, yes. If you're looking for Lord Shuukin..."

"I'm right here, Lady Yuriga."

A hand reached out of the stretcher that had just been lowered, and it

waved to the three of them. Yuriga rushed over, and there was Shuukin,

looking much paler than the last time she saw him.

"Sir Shuukin..."

"Ah ha ha... It's been a while, Lady Yuriga. I'm glad that you seem to

be well. Sorry you have to see me like this."

"No... Don't be..."

Shuukin was acting cheerful, but his expression couldn't fully hide the

fact that he was suffering.

Yuriga didn't know what to say. As she struggled for words, someone

planted their hands on her shoulders. Turning to look, she saw it was

Tomoe, who nodded with a soft smile on her face.

Looking at Shuukin over Yuriga's shoulder, Tomoe said, "Hello, Mr.

Shuukin. I'm Yuriga's friend, Tomoe."

"Sir Souma's little sister. I remember seeing you at a distance during

the demon wave. I apologize for causing the men and women of the

Kingdom of Friedonia trouble because of my own shortcomings this time."

"Don't say that! You did a great job as my brother's representative!"

Yuriga protested, and Elulu emphatically agreed.

"That's right! You saved me many times, Lord Shuukin. And not just

me. The only reason we were able to liberate the Father Island at all was

that you and your men fought so hard."

Elulu took Tomoe's hands, holding them tight as she bowed to her.

"So, please, if there's anything I can do, I'll do it. People of Friedonia...

Please save Lord Shuukin."

"I'm not the one you should be saying that to..." Tomoe got flustered by

Elulu's desperate appeal.

However, when Tomoe felt the hands she was holding start to tremble,

she came back to her senses. Seeing someone who was more uneasy than

she was, she decided she shouldn't worry the girl any further.

Tomoe squeezed Elulu's hands right back.

"But Dr. Hilde and Dr. Brad have my brother's trust, and I'm sure

they'll do something about the Spirit King's Curse. So it's going to be fine."

"Right!" Elulu did her best to smile.

As Shuukin watched them warmly, he said, "I see you've made yourself

a good friend in the Kingdom, Lady Yuriga."

"I just can't get away from her. That's all," Yuriga said, looking away

peevishly.

Shuukin chuckled. "A bond is a bond either way. If I were with my

friend, Fuuga...I could run ten thousand miles. Here's hoping I can run

together with him again."

Shuukin looked up to the heavens as he spoke. Yuriga shrugged.

"I'm sure you can. Didn't you hear what that little kid was saying?"

Then, putting a hand on her hip and thrusting her chest out, she said, "Well,

maybe it's hard to sense this without actually living there, but the Kingdom

of Friedonia's potential is incredible. If they're serious about this, I'm sure

you'll be fine."

"It's an amazing country, huh?"

"I'm always writing to my brother to make sure he doesn't

underestimate them."

And so, Shuukin was moved into the treatment facility at the port city,

with Tomoe, Yuriga, and Elulu in tow.

◇ ◇ ◇

A research facility was established at the port city. Here, Hakuya and

Ichiha kept records of the various dead monsters sent from the Spirit

Kingdom of Garlan. They also cross-referenced which monsters were

fought by those who had contracted the Spirit King's Curse.

In another room in the facility, Brad was performing autopsies on

monster remains, and using a microscope to search for the parasites

responsible.

On the table in front of Ichiha and Hakuya was a lineup of monsters

that Ichiha had drawn based on the accounts of patients who'd fought them.

Looking down at them, Hakuya finally picked out two.

"I think these are the most suspicious."

"Yeah...I agree," Ichiha replied with a nod.

The two chosen were a snail ant, which was a large ant with a spiral

shell for its midsection, and the snail bee, which had a spiral shell on the

part with its stinger. A common feature they had was their distinctive spiral

shell.

Ichiha collected all the pictures of insects with similar characteristics,

saying, "Now that we've gathered all these accounts, we can see there are a

lot of monsters with this spiral shell trait. And mollusks are famous for

causing illness if not properly cooked."

"Hilde was telling me that's also the work of small bugs...parasites.

And then there were those endemic diseases His Majesty mentioned. There

were mollusks involved with them too."

Before Hakuya and the rest were sent to this port city, Souma had told

them that the Spirit King's Curse had some things in common with a

disease from his old world called schistosomiasis, which was also caused

by parasites in the blood. He talked about a case where parasites in the river

used mollusks as an intermediary host to eventually infect farmers working

in the mud. Souma had gone to the Sugiura Memorial Museum in Showa

Town with his social studies class, and he had to write a report about it

after, so he remembered a lot of the details.

"Memories from when you're little really stick with you. I thought

writing that sort of report was just a pain back then, but you never know

what's going to come in handy..." Souma had said earnestly. And so they

kept that in mind too.

Hakuya touched his chin as he thought. "The Spirit King's Curse is

likely caused when warriors fight insect-type monsters with the shell trait

and get their fluids on them."

"That's right," said a third voice.

Turning towards the sudden inclusion, they saw Brad had come in

wearing his white coat while carrying Ludia on his back. Not a lone wolf

and cub, but a doctor and baby.

Brad produced two vials from his coat pocket and laid them down on

top of the monster drawings. They were filled with fluid and had little

things inside them.

"One of those is the parasites that came out of a patient who died of the

Spirit King's Curse. They're big enough to be seen with the naked eye,

right? Hilde says they match the ones in Gerula's blood that she saw with

her third eye."

"I see. So then these are..."

"The parasites that cause this disease?"

Hakuya and Ichiha both let out a sigh as they looked at those parasites,

each no larger than a grain of sand. They were small enough that Ichiha,

who always wore glasses, struggled to see them. It was hard to believe this

organism was the cause of so many deaths.

"It's inconvenient not having a name for them," Brad continued. "They

are bugs that hide in the blood vessels, eating away at our magicium... Let's

call them blood-borne magic-eating bugs. And we found what seems to be

magic-eating blood bug larvae in the dead bodies of monsters."

Having said this, Brad showed them the other vial. It looked similar to

the others, but this time it was hard to see anything other than liquid inside.

Ichiha squinted but couldn't make out anything.

"The larvae...are in there?"

"They are. But they're only large enough that someone with good

vision might just barely be able to make them out. It's only with the threeeyed race's third eye or a microscope that they're easily visible."

Brad picked up the vial between his fingers. "The monster I found these

in had a spiral shell, like you said. The infection is caused by contact with

fluids from monsters with them...just like you were thinking."

"Is it possible for there to be person-to-person transmission? Like if we

touched someone's infected blood..." Ichiha asked.

"You don't want to try it, that's for sure." Brad crossed his arms and

cocked his head to the side. "But it seems like there are practically no cases

of transmission that way. Even if you come in contact with their blood, so

long as you wash and disinfect yourself afterwards, there shouldn't be a

problem. The risk to those who get covered in monster fluids during battle

and then don't clean themselves is far higher."

"What measures can be taken to prevent infection?" Hakuya asked.

"Well... First of all, you could stay away from them. Fighting up close

with these monsters is dangerous. If you really have to fight them, then

ideally you want to finish them with ranged attacks, at a distance where

their fluids won't get on you."

"It seems they're already doing that, but I'll let them know to take

special caution with monsters that have spiral shells."

"Also, if you get fluids on you, wash and disinfect anywhere it touches

immediately. If you leave it as is, you run a higher risk of infection."

"Understood," Hakuya said, nodding. "Sir Ichiha."

"Right! I'll go let the people from the Great Tiger Kingdom know!"

Ichiha replied before running off.

Brad scratched his head as he watched him go. Turning to Hakuya, he

said, "Still...I know I shouldn't say this, but I never expected to find the

cause so easily... This would never happen with a normal disease."

"You're probably right. It seems a lot of things came together to help us

out. We had you, who is familiar with the inside of the body; we had

experts on monsters; Hilde, who can remove parasites with magic; His

Majesty's knowledge of a disease in his former world; and..."

"And someone who donated his body to the cause."

They both looked pained as they remembered Gerula, who had fallen

victim to the disease.

"Yes... It was all thanks to this confluence of events."

"So it only worked out by coincidence, huh?"

"Perhaps. However, without His Majesty's decision to pursue medical

development, Madam Hilde's and your assistance, and the contribution of

Gerula, who wanted to save his homeland, such a coincidence wouldn't

have happened. Even if it was the result of chance, our will to overcome

diseases is what brought it to fruition."

"You've got that right."

Brad was often a contrarian, but on this, he readily agreed.

◇ ◇ ◇

Patients from the Father Island afflicted with the Spirit King's Curse

were arriving at the medical facility in the port city. These were ones with

relatively minor symptoms, and would be experimental subjects to test the

efficacy of the treatment Hilde had discovered.

The first subject was going to be Shuukin.

"I've heard the reports from Yuriga, so it's not like I don't trust the

Kingdom's medical science, but I don't want to test anything on my men

when I don't know the risks. Besides, if I show them that I've accepted your

treatment, my quick-tempered lot will be more willing to submit to it too."

Shuukin was lying in bed as Hilde examined him. Tomoe, Yuriga, and

Elulu were watching at a distance. Yuriga seemed unsteady on her feet, and

Tomoe had to help her to stand.

"Are you okay, Yuriga?"

"Ungh... I'm a little dizzy, but I'll be fine."

Hilde made a shallow incision in Shuukin's arm with a scalpel. Shuukin

didn't bat an eye at it, but all three of the girls gulped. Hilde immediately

began using light magic on the wound. It was a little small and shallow, but

it took far longer than normal to heal.

"Your case is fairly advanced," Hilde said with a sigh as she examined

him. "The blood-borne magic-eating bugs—okay, apologies to Brad, but

that's way too long. I'm just going to call them magic bugs... Anyway, the

magic bugs have damaged the magicium in your blood pretty badly. If I was

going to exterminate them with just the magicium you have left, it would

take a long time. Considering your symptoms, that'd be the death of you."

"Is...that right?"

"If I did it the normal way, yes. Honestly...since we're trying to test the

safety of this, I'd have preferred a subject who had somewhat lighter

symptoms," she grumbled.

Shuukin laughed. "Sorry for putting you out like this. But Lord Fuuga

entrusted me with those men. If this body of mine is no longer fit to stand

on the battlefield, then let me offer it up as a test subject."

"I hate the way you warriors think... But if that's what you're going to

say, I'm going to take you up on it."

With that, Hilde produced a large bottle containing a dark red liquid,

causing Shuukin's brow to furrow as he saw it.

"What is that?"

"The blood I took from that girl over there," Hilde replied, pointing to

Yuriga. Shuukin's eyes went wide.

"From Lady Yuriga?!"

"Yeah. The method I've developed for treating the Spirit King's Curse

involves identifying the magic bugs in the blood and using an awareness of

where they are to control the magicium in the body to eliminate them with

light magic. If I know what effect the magic bugs have on the body, I can

treat the other symptoms too, but...Brad's still busy dissecting cadavers and

looking into that. That's why I'll be focusing on eliminating the magic bugs

for now. If your magicium has been thoroughly destroyed, though, I can't

do it... Which is what this is for."

Hilde held up Yuriga's blood for Shuukin to see.

"I'll give you a transfusion from this girl, who's of the same race as

you, and supplement your magicium with hers. I've already checked that

she's a viable blood donor for you."

"N-No! How could I make you shed the blood of my liege's sister?!"

Shuukin was hesitant, but Yuriga, despite seeming somewhat anemic,

waved her hand as Tomoe helped her stand.

"Oh...don't worry about it, Sir Shuukin. My brother needs you on his

path to supremacy, and it's no big deal for me to give up a little blood for

that."

"Lady Yuriga..."

"You should be grateful for the situation, and accept it with grace. It

was a stroke of good fortune that there was a healthy member of the same

race here to act as a donor... Some lives couldn't be saved even after

coming up with this method," Hilde said, her expression clouding. "It was

all too late for the high elf patient we saw back in the Kingdom. The only

other high elf there wasn't a blood-type match for him, so we couldn't even

have tested this method. Although, with the organ damage he had already

suffered, it would have only extended his life a little at most... His name

was Gerula Garlan."

"Huh?! Uncle..." Elulu murmured.

Hilde lowered her eyes before responding. "He was...a relative of

yours?"

"Yes. He knew he didn't have long, and was looking for a way to use

what life he had left. I see... So he passed away in the Kingdom, then..."

Elulu looked down as tears filled her eyes.

In an uncharacteristically gentle tone, Hilde said, "To that end, he

passed away with one of his own kind watching over him, and a peaceful

expression on his face. It was only thanks to him offering up his body that

we uncovered the true nature of the disease, and I was able to come up with

this treatment."

"My uncle's death...wasn't in vain then?" Elulu asked, looking up, and

Hilde gave her a firm nod.

"I'd never let it go to waste. None of us would."

Sniffling, Elulu replied, "Right!"

"It sounds like I'll have to be prepared too, then," Shuukin said,

exposing his arm with a look of determination. "Princess Elulu's uncle gave

his life to help find this treatment. If my body can be the one that proves it's

effective, I couldn't be happier. Lady Yuriga, I will be borrowing your

blood."

With Shuukin's resolve set, Hilde began the treatment. First they

extracted some of Shuukin's blood, then transfused Yuriga's healthy blood

into him. Because blood couldn't be preserved for as long as in Souma's old

world, time was of the essence. And so the blood was transfused. Hilde also

used light magic to eliminate the blood-borne magic-eating bugs.

Shuukin sweated heavily throughout the procedure.

He didn't seem to be in pain, but the feeling of something messing

around inside his body was unpleasant. It was exhausting too, and

eventually he passed out like someone had flipped an off switch.

Two hours went by...

Hilde used light magic on every blood vessel in Shuukin's body. She

sent an image of the magic bugs to the magicium inside the body, and then

they destroyed them. There was no standard for how many it might be safe

to let escape, so she was as thorough as she could be.

After a long time, Hilde stopped casting magic on the body.

"Please...let this work."

And then, making another incision on Shuukin's arm, she tried casting

light magic on it. When she did, it still healed slowly, but faster than before,

showing that the magicium in the body was functioning properly.

"Whew..."

Hilde collapsed into a chair, exhausted.

"Um, Doctor. Will Lord Shuukin..." Elulu asked, unable to wait any

longer.

"I can't say for certain until I've had time to observe," Hilde said,

waving her off. "But this should have eliminated the magic bugs in his

blood. I'd say we can call it a success so far."

"Really?! Thank goodness!" Elulu cried out with glee, gently taking the

sleeping Shuukin's hand.

With a sideways glance at her, Hilde let out a great sigh.

"For now, I think it's safe to say we've established a treatment. If it can

be treated when it's advanced this far, then we should be able to treat the

others with comparatively light symptoms without even needing a blood

transfusion. But I hear there's still far more patients on the Father and

Mother Islands."

Hilde leaned back in the chair, looking up at the ceiling.

"It took all this time and effort just to treat him. Much as I hate to admit

it, I can't handle all of them with just the doctors we've brought with us...

No, even with all the doctors in the Kingdom, it still wouldn't be enough.

What can we do..."

"It will be okay," Tomoe said, leaning in to peer at Hilde's face. "Big

Brother stayed in the Kingdom because he said there are things he needs to

take care of. I'm sure he has an idea. So...it's going to work out."

"Here's hoping..." Hilde replied, smiling wryly at Tomoe's total belief

in her big brother.

◇ ◇ ◇

One week later...

With the treatment of the first batch of patients at the port city

complete, they were all on the way to recovery. Shuukin had had the

heaviest symptoms, and even he had recovered to the point where he was

doing training as a form of rehab. When Shuukin stood up and got out of

bed on his own, Elulu jumped into his arms in glee.

And now, on this day, Prime Minister Hakuya; Tomoe, Ichiha, and

Yuriga; Hilde the doctor; Brad the surgeon; Shuukin; and Elulu were

gathered in one room to discuss the current state of things and what they

were going to do going forward.

"How about we start with the condition of the patients?" Hakuya

suggested.

"That's no problem," Hilde replied. "They're all on the way to

recovery. Even the one with the worst case of it, who's right here with us."

"Thanks to you, Doctor," Shuukin said, bowing his head. For some

reason, Elulu, who was next to him, bowed hers too.

With a wry smile at the two of them, Hilde told Hakuya, "For now, I

think we can safely say that we've established a treatment for the Spirit

King's Curse. The light mages with a knowledge of medicine should be

able to perform it the same as I did without any problem."

"That's a relief to hear," Hakuya said with a nod before looking to

Brad. "Now, what can you tell us about the blood-borne magic-eating

bugs...the magic bugs?"

"All we know so far is you can get infected with them by touching the

fluids that come out of the spiral shell part of a monster's body," Brad

replied, crossing his arms. "But when you consider the almost total lack of

infections coming from patients, I think the magic bugs only have the

power to infect humans when they're covered in monster blood."

"Is this that 'intermediary host' thing that His Majesty told us about?"

"Yeah, that's probably it."

Souma had told them about Japanese schistosomiasis. It was an

endemic disease from the world he came from, and it infected people

through mollusks that lived in the rice paddies and rivers. In the country

Souma lived in, they had overcome the disease by preventing the mollusks

from reproducing and eliminating the environment that allowed the

parasites to exist.

"It's not clear if the demon wave caused preexisting parasites to change

inside the bodies of the large number of monsters it produced, or if they

existed in the monsters' bodies all along. The one thing we do know is that

to stop the chain of infections, we need to completely eliminate the

monsters with spiral shells that are causing it."

"I've reported that to our forces on the Father Island. They're to make

eliminating any spiral shell monster their top priority. They have strict

orders to do so from a distance; defeating the enemy with long-ranged

attacks or magic, and avoiding contact with their blood."

Elulu nodded at Shuukin's explanation.

"I've given the same report to my father, the Spirit Kingdom King, on

the Mother Island. I think that should help lower the rate of new infections,

but..." Elulu's expression darkened. "There are still a large number of

people suffering from the Spirit King's Curse on both islands. Could you

possibly perform the Kingdom's medical treatment on all of them? Please!"

Elulu bowed her head and Shuukin joined her.

"I'm asking you too. Please save my wounded soldiers and the high

elves."

"That seems to have been His Majesty's intention all along..." Hakuya

said.

Hilde began vigorously scratching her head.

"But the patients on both islands vastly outnumber this first group,

right? And from what I hear, many of them are in even worse condition than

Sir Shuukin was. I already told little Tomoe and her friends this, but we

don't have nearly enough people to handle them all with just the doctors we

brought here. Even if we brought every light mage in the Kingdom with

medical knowledge, it still wouldn't be enough."

"Also, it would be inefficient to bring them all to this port. There's no

telling how long it might take if we only brought them in batches as large as

we can house here, and we don't have enough blood for Hilde's treatment

either," Brad added, pointing out further problems. He looked at Yuriga.

"We got lucky that her blood happened to match Shuukin's, but if it hadn't

then his treatment would have been delayed further... Well, if it came to it,

we'd have relied on using blood from another race."

"Hm? It's possible to do blood transfusions between different races?"

Hakuya asked.

"If you're asking if it's possible...then, yes. Even if people's races are

different, so long as the blood types match, there is no problem with doing a

transfusion, but...the medical society doesn't encourage it," Brad answered

awkwardly.

"Why is that?"

"A little knowledge can lead to rampant superstition. Blood transfusion

isn't an established medical practice outside of our country. What do you

think would happen if it became known that you can transfuse the blood of

a long-lived race like the elves into humans? What if that started a baseless

rumor that doing so could extend a person's life or restore their youth?"

"I see... I'd rather not think about it." Hakuya got depressed when he

considered what would happen.

Hunts for members of the long-lived races, completely disregarding

their rights, and trafficking in their blood—every illegal method might be

tried. The long-lived races wouldn't just take it, of course. In the worst case,

it could develop into a civil war.

Brad nodded. "Let me just tell you straight up, their blood doesn't have

that sort of effect. But if people are ignorant, they won't believe you when

you tell them. We should save transfusions from other races until the people

have been enlightened as to how it works."

"You make a good case... It would be advisable to stick to transfusions

between the same races until then. That being the case... Should we go to

the Spirit Kingdom of Garlan, where there are members of the same race, in

order to treat them?"

Hakuya brought his hand to his mouth as he thought, looking at Tomoe.

"If I recall, you and your friends are on summer vacation right now,

correct?"

"Yes. We have about another month."

"It's kind of a problem that I haven't even touched my assignments

yet..." Yuriga said, getting dispirited. "If I don't get them done, I'm in for

more remedial lessons..."

Hakuya thought for a short time, and then made his decision.

"Yes, let's go to the Father Island and treat the people there. Since

Shuukin has recovered, we'll want him leading his men to prevent further

infections."

"Sure! Thank you, Sir Hakuya!"

"Thank you so much!"

Shuukin and Elulu were overjoyed, but Hilde's expression was still

grim.

"I'm fine with going there, but that doesn't change our shortage of

staff."

"Ah, as far as that goes, I suspect..." Hakuya began to say, but hadn't

even finished before it happened.

A messenger rushed into the room, handing a letter to Hakuya.

"It's a report! It came from the Kingdom of Friedonia, by messenger

kui! It's from His Majesty!"

"Oh! Let me see it."

Hakuya accepted the letter and looked through it. When he was done,

he let out a sigh of relief. Everyone could immediately tell that it wasn't a

negative report.

Looking around at each of them, he said, "The manpower shortage is

resolved. Let's head to the Spirit Kingdom at once."
