After Akeno sends the urgent chat message, Misogi, Rimuru, and Kazuma return to Takagi estate via Misogi's teleportation.
Upon arrived, they saw many strange being coming on horde and about to surround the estate.
"What the heck are these things?!" Shouted Kazuma while he and the other two looked down from the hovering Vimana, seeing the alien-like creatures coming on horde to the Takagi estate.
The alien-like creatures looked like a cross between an insect and a human, having a human head with insectoid eyes and a mandible. They're standing with two grasshopper-like legs and have two tails with a mouth on each of their ends. Their saw-like hands are folded like it was praying. All of them are colored white.
"Anti-Thesis..." Said Misogi with a frown.
Hearing Misogi's words, Rimuru widened his eyes, "All of them are Anti-Thesis?!"
"Yeah. But this horde are just the minions." Answered Misogi without looking at him, "If I remember correctly, they're being created by two birthing couples Anti-Thesis named 'Mother and Father'."
"Mother and Father?" Kazuma raised an eyebrow while glancing at Misogi with a weird look.
"Why are you giving me that kind of look? It's Anshin'in-san who called them that!"
"Whatever they're called, we need to eliminate them. Look, Akeno-san and Kurumi-san and someone I didn't know are fighting them." Rimuru reminded the two as he jumped from Vimana to the ground below and started assisting the unknown person who seemed to be struggling the most.
Misogi and Kazuma looked at each other and nodded. The two of them followed Rimuru by jumping down from Vimana and heading over to different directions where the defenses were low.
~~~***~~~
A Numerous Anti-Thesis minion were frozen to death; the ones who were not frozen were being impaled by many chunks of sharp ice lances made by Saya.
"This ice magecraft is useful." Said Saya with a complicated expression as she created a sharp and long thin ice in her wand and with a wave of her hand holding the wand, she bisected two Anti-thesis who came close to her, "But I'm still not used to this power. I'm still far behind in mastering this."
Saya continued to fight using her ice magecraft, but the Anti-thesis minions kept coming in a horde at her, making Saya have difficulty fighting an army of mobsters even with the assistance of the guards from Takagi estate who were firing their firearms behind the makeshift barricades wall even when it only staggering them.
"Ugh! If this continues, I'm the one who will fall first! My stamina is not enough to fight an entire army of these alien-looking things!"
She keeps creating sharp ice lances and throws them toward the horde of Anti-thesis, but many also manage to run past her attack and charge at Saya and the Takagi estate behind her.
"Oh shit!"
"Excalibur Morgan!" A shout can be heard, and then a blast of dark energy is coming from her right side. Eliminating the horde of anti-thesis who approached her and the Takagi estate. The dark blast also gouged the ground in front of her in a wide area.
Saya turned toward her right side and saw a light blue-haired, androgynous person holding a black ominous European sword in his hand coming toward her.
"Let me help you- E-eh?! Scathach-Skadi?!" The person stopped on his track and stared at her with an incredulous expression.
"Tempest! Thank god you arrived!" Saya breathed a sigh of relief when she saw Rimuru coming to help her.
"That voice... Takagi-san?!"
"Yes, it's me!"
"Wha? How? When?" It's understandable because Kazuma didn't tell Rimuru and Misogi about giving Saya a caster class card; Rimuru was pretty much confused at how the heck Saya could turn into Scathach-Skadi.
"I explain it later! For now, let's defeat these things first!"
Rimuru was confused, but since a horde of Anti-thesis was coming at them, he decided to eliminate them first, as Saya suggested.
~~~***~~~
On the north side of the Takagi estate, Akeno who's wearing her Herrscher of Thunder Battlesuit, could be seen eliminating the Anti-thesis with Sakura's swordsmanship style, holding the Seven Thunder of Retribution in katana's form.
She also let Kurikara out from her Imaginary Space. The red dragon honkai beast roared as it tearing through the horde of Anti-Thesis minion.
With her body covered in lightning, Akeno executed a fast movement that cleaved many of the Anti-thesis, making them shriek in a creepy tone before they died.
"Ugh, their bodies are though. My hands almost getting numb after slashing at them." Complained Akeno. She then threw many one-yen coins into the air and covered them with electricity. Making the railgun projectiles shoot at high speed at the horde of Anti-thesis, raining them to death, "When my thunder isn't effective enough against them, I was lost what to do, but fortunately, I still had many one yen coins in my inventory and Misogi-kun's gift."
Suddenly, a flaming spear came from the side and pierced many Anti-thesis in one straight line. Making them burned after the spear pierced them.
"Akeno-san! I come to help!" Shouted Kazuma with his golden spear came back in his hand again after being thrown, he then noticed the red dragon honkai beast, "Wow! Is that Kurikara!?"
"Kazuma-kun! What are these things!? My thunder almost didn't work on them!" Akeno said, ignoring Kazuma's awed look at her Kurikara.
"Misogi said they're Anti-Thesis!" Yelled Kazuma as he created many crimson solid energy spears above him and launched them toward the horde of Anti-thesis and exploded upon impact. "It seems that these types have resistance against thunder elemental attack! And my flame is working fine against them!"
"Then let's fight together! There's still many of them left."
"Roger that!" Replied Kazuma.
And they went toward the army of Anti-Thesis in front of them without fear.
~~~***~~~
""""""""Aleph!"""""""
*Bang*
Kurumi and her many time clones used the first bullet to accelerate their external time to increase their speed to fight the army of Anti-Thesis.
She also uses her shadow power to summon many pale white hands to restrict and bind the movement of her enemies.
"Oh my. This is a troublesome situation." Said Kurumi with a frown. "My time abilities aren't working on them. But the bullet made from my reiryoku in my Flintlock and Musket apparently can damage them."
Indeed. Kurumi's time manipulation abilities aren't working on the Anti-Thesis. Her Reiryoku bullets from her pistol are only enough to damage the enemies, not kill them, which made Kurumi shoot them multiple times to kill them. She uses the first bullet, Aleph, to increase her speed to shoot them down quickly.
"I thought I could defeat them by using my own power. Should I use the Twins of Eden and summon Bahamut too?" Kurumi pondered.
"I think Twins of Eden would be enough." Said a familiar voice coming from behind her.
Kurumi turned to look behind her.
"Ah, darling! You came!"
"Well, I came to help you since your power seemed not working against Anti-Thesis." Said Misogi as he walked to her and stopped at her side.
"These things are Anti-Thesis?" Asked Kurumi as she blinked curiously.
"More like the minions birthed by their leader." Answered Misogi casually while looking in front of them as many minions of the Anti-Thesis were getting barraged by reiryoku bullets from Kurumi's time clones.
"By the way, when I arrived here earlier, there was someone who used ice magic to defend the other side of the estate; who's that?"
"Someone using ice magic? Oh! You mean Saya Takagi-san?"
"Her? How did she have ice magic?" Asked Misogi with a confused expression.
"Fufufu~ it seems Kazuma-san has been giving his girlfriend something very nice." Answered Kurumi with a suspicious tone and laugh.
"... Why did your phrasing seem so ambiguous?" Said Misogi with a blank face, "Well, I'll ask Kazuma later. For now, let's deal with these things first."
"Yes, darling~"
Kurumi then took the Twins of Eden from her inventory and equipped it on both hands.
For Misogi, he tried something new. He manifested many Subspace Screw Lances on each side of him. He then used telekinesis to put them together on each side of his arms, and after they formed into skeletal hands made from his Subspace Screw Lances, Misogi nodded, and each Screw Lance that formed the Skeletal hands started rotating at high speed. The image is as if Misogi has two hovering extra big hands made from rotating screw lances on each side of his body.
Kurumi looked at Misogi with a blank expression after seeing the brutal weapon, "New technique, darling?"
Misogi glanced at Kurumi with an evil smirk similar to the past Misogi who was fighting his opponent.
"Yep, it's a big improvement from only when I was just using a big screw to fight in close-quarter combat." Answered Misogi. Returning his attention to his new skeletal 'Hands' which each of its fingers rotating at high speed. It looked capable of tearing his opponent to shreds when holding or touching them.
For experiment, Misogi reached to a few Anti-Thesis minions in front of him with his new weapon. True enough, they easily shredded to pieces after being touched by its rotating fingers.
Seeing his new weapon successfully killing its enemies, Misogi's evil smirk widened, "Well then. Let's start the massacre!"
After saying that, Misogi, with his two new 'skeletal' hands, ran toward the army of Anti-Thesis and tore them apart while laughing sadistically while also creating many subspace lances in the air and launching them toward his enemies.
Kurumi, who caught a glimpse of Misogi's evil smirk, blushed heavily, "If Akeno-san saw darling's smirk and how brutally he is fighting right now, I'm sure she would be aroused until climax. And the same goes for me too..." She muttered quietly before joining Misogi by assisting him with firing miniature black holes toward their enemies.
With that, they kept eliminating Anti-Thesis minions for almost five hours. But slowly and surely, their numbers decreased significantly, making the exhausted combatants, Saya, Akeno, Kurumi, and Kazuma, feel a bit relieved.
And to the relieved combatant, one hour after non-stop fighting, the last Anti-Thesis minion was struck down by Akeno's sword.
"Finally! Over!" Shouted Kazuma as he dropped his body to the ground to lie down.
"I'm glad this is over. These Anti-Thesis are more difficult to struk down and have sturdier body that the zombies." Akeno dropped down. Sitting on the ground as her Raiden Ei's outfit, or her Herrscher of Thunder Battlesuit, dissipated. Leaving her on her normal outfits which is Kuoh Academy female uniform.
Kurikara also went back to Akeno's Imaginary Space.
"Sorry to interrupt, but this is still not over yet, guys." Said Misogi as he arrived while piggybacking Kurumi whose exhausted as she low on her reiryoku.
"Seriously?" Rimuru said as he also arrived while supporting Saya who looked like she can fell asleep anytime with his shoulder, "Don't tell me they also have Anti-Thesis factory here?"
Rimuru then let go of Saya as she tried to lie up on the ground still in her Scathach-Skadi form. Totally exhausted for this is her first time fighting against Anti-Thesis while also using class card on her first time.
"Darling, can you put me down?" Kurumi ask misogi, "I also want to sitting on the ground."
"Alright." Misogi put her down gently.
"Thank you."
Kazuma, who's lying flat on the ground then asked Misogi, "So, what do you mean this is not over yet?"
"The one who 'birthed' them haven't appeared yet."
"You mean the 'Mother and Father'?" Asked Rimuru and Misogi nodded. Earned them a raised eyebrows from the girls at the name.
"By the way Misogi. Why you say that they 'birthed' not created?" Asked Kazuma.
Misogi scratches his head at Kazuma's question, "Well... How I say it without making it awkward? Ummm... You see they're basically-"
*Rumble*
Misogi's sentence was interrupted by a sudden earthquake that shooked violently.
"Speak of the devil, here it's comes." Said Misogi while looking awkward, "You better see it for yourself."
Misogi's words only left them with question marks above their heads. Misogi then looked at a certain direction, making the rest of them followed him.
For a few second, there's nothing where the place Misogi are looking as the earthquake becoming very violent. But suddenly something very big appeared from the ground bellow while making a loud noise with dust and smoke covered the place.
After the smoke cleared and the earthquake subsided, it revealed what was covering it, and making everyone get a clear look at the Anthi-Thesis.
"..."
"..."
"..."
"..."
"..."
"See, it would awkward if I'm the one who's saying it." Said Misogi wryly as everyone beside him are totally speechless after seeing it.
"... Umm... Why it's look like...?" Saya mumbled with twitching eye.
"... A freaking V*gina Kaiju...?" Muttered Kazuma in disbelief.
Indeed, the Anti-Thesis called 'Mother' are shaped like a woman's private part except white in color. It's body is just a flesh with tentacles growing from its back.
As the group are still staring speechlessly at the form of the Anti-Thesis, the 'Mother' roared and its body swelled and releasing many Zombie Factories and a giant white spherical flesh.
"This thing is the one who created Zombie Factories?!" Yelled out Rimuru.
But before any of them can comment anything more, The white spherical flesh morphed into an army of the Anti-Thesis minions. Making the group sans Misogi and Rimuru groaned.
"Are you guys still have enough energy to fight?" Asked Misogi.
"I'm a bit tired. But the others seemed almost run out of juice." Answered Rimuru.
Misogi let out a sigh, "There's no choice then."
Immediately after Misogi said that, every members suddenly feeling themselves not tired. They're feeling very invigorated instead.
"Huh? How I'm suddenly full of energy?" Kazuma said as he stood up from the ground. Doing shadow boxing as if to prove that he's not tired.
The other also confused by the loss of their tiredness.
"I erased you guy's tiredness for the time being. But it will come back later if you fightimg too long. " Confirmed Misogi as the other looked at him, "We need to take care of them so you needed at full of energy."
"... I know we always joking/teasing about Misogi-kun to erased his tiredness in our night activity. But this..." Akeno said speechlessly.
"Now that we are the one who receiving it. It feels..." Followed by Kurumi in intrigued tone.
"Hey you two! Don't lost into your own fantasy! Here they come!" Shouted Kazuma as he once again went straight to the enemies.
"Kazuma! Wait up!" Yelled Rimuru as Kazuma started to massacre the zombies and Anti-Thesis minions in front of them.
Misogi sighed at Kazuma's action, "I was about to tell him that we should deal with the Mother Anti-Thesis first so that it cannot birthing the zombie factories and Minions anymore. Oh well, we can just eliminate the small fry first."
The MCG group plus Saya then also followed Kazuma to the front line to battle them.
Misogi use his new skeletal hands weapon to shred the enemies to piece. Akeno with high speed movement slice and bisected many zombies and Anti-Thesis minions. Saya, with Scathach-Skadi ability using ice rune magecraft to impale the enemies with sharp ice pieces. Kurumi using the Star of Eden to increased the gravity of the enemies by two hundreds times, making them crushed by their own weight, she didn't use her divine key to make a blackhole since it could result in friendly fire, in other words suck the enemies and her allies into it. And Rimuru for the first time in this world, didn't use his magecraft and UBW. Instead he used his black flame skill that he got after absorb Ifrit since flame elements are more effective against his enemies.
As they fight, more and more of the zombies Factories and Anti-Thesis Minions keep being birthed by Mother Anti-Thesis, making the six who fighting them complained.
"Argh! This will never end since it creating more and more of them!" Complained Kazuma.
Rimuru, who's heard Kazuma's complain also feels annoyed, "Yes, I agree. This is getting repetitive."
Misogi also nodded at their words, feeling pretty much irritated, "I also agree with you two. Wait for a bit I will do something. Can you guys hold the line?"
Rimuru and the other who heard his words nodded their head.
Seeing their reaction, Misogi use his spatial awarenes to allow him to grasp the surrounding space, recognize the movement of objects within that range as shapes, and perceive them in real time. For simple explanation, this ability allow Misogi to detect any object via sensing the space around him without seeing his surounding with his eyes.
'There's around 50 zombies factories, 126.867 zombies and 200.598 Anti-thesis.' Said Misogi in his mind after use the spatial awareness, "Well, here I go go."
His outfit chaged to Herrscher of Void Battlesuit wich resemble of Fatal Phantom oitfit. Misogi raised his two arm and clenched his fists.
"Compress."
With that single word from Misogi the space of every zombie Factories, zombies, and Anti-Thesis Minions are shrinking quickly as if being compressed into tiny ball and then dissapear completely.
"Fuuh... That's working, but consuming more brain power even with pararel thought. Sadly the Mother Anti-Thesis are fine and I can't reached it. It seems I need to train this more." Said Misogi while wiping a bead of sweat on his forehead.
Everyone was looking at Misogi in disbelief and awe. Eliminating more than one hundred thousand enemies with a single move. How overpowered he can get!?
"Hey, why are you guys staring at me for? The Mother Anti-Thesis still alive, we need to kill him before it giving birth to more Minions and zombies!" Yelled Misogi before he running toward the direction of the V*agina Kaiju.
Rimuru and the other looking at each other. Isn't he himself are enough to kill it?
But they dismiss the thoughts and start running to follow after Misogi to kill it anyway.
