They entered, and the young man found the injured woman from Asakusa in a hospital bed, being tended to by Tamayo. Tamayo was seen standing by the bedside wearing a doctor's robe over his kimono.
"Sorry for leaving you guys with that job." The young boy said in a guilty tone of voice.
Then the young boy looked at the woman on the hospital bed. "Is she okay?"
"She's fine, but her husband has turned into a demon. We have to keep him in the basement." Tamayo explained to the young boy.
A cold silence fell in the room. Tamayo looked at the woman in her care with sad eyes and the boy also looked at her with a sad expression.
"Is taking care of injured humans comfortable for you?" The boy asked with a sad tone of voice and expression.
Suddenly, Yushiro punched the young boy in the chest with enough force to make the boy cough from the pain.
With an annoyed expression, Yushiro said, "As demons, we should be able to endure the smell of flesh and blood. You want us to take care of humans too?"
"Sorry." The young boy immediately lowered his head regretfully.
"Stop it! Why does it have to be violent?" Tamayo immediately rebuked Yushiro's slightly insolent attitude.
Then Tamayo looked at the young boy, and then the young girl next to the young boy in turn. "I haven't introduced myself yet. My name is Tamayo and this boy is Yushiro. I hope you guys can get along."
The boy also came to his senses. "Ah yes, that's right. My name is Tanjiro Kamado and this girl is my little sister, her name is Nezuko Kamado.
With eyes rounded like acorns, Tanjiro glanced secretly at Yushiro who was shrouded in a very unfriendly black aura. "He's very hard to get along with and I can't do anything, right?"
"And to answer the question. This job is fine for us, I'm more used to it than most demons." Tamayo exclaimed as he touched himself.
Tamayo also revealed that she had modified her body to remove Muzan's curse and her dependence on human flesh. At the time of explaining this, Tanjiro was confused by what Muzan's curse meant.
In addition, Tamayo also explained that both he and Yushiro only needed to drink human blood to survive. This made Tanjiro silent and even more confused with so many questions.
Then, Tamayo took off the doctor's robe and sat on the floor on the tatami. Tanjiro and Yushiro also sat down. But, before that Tanjiro put down his luggage, which was the box used to hide Nezuko from the sun and people.
Tanjiro sat down, while Nezuko immediately lay down on the tatami which was very comfortable for her. Tanjiro wanted to reprimand Nezuko who was childishly a little impolite. But, Tamayo smiled and allowed it.
The three of them sat on the tatami floor facing each other. Except for Nezuko who was lying on the tatami floor wriggling comfortably, like a silkworm.
"Sorry for Nezuko being rude." as Tanjiro lowered his head.
"No problem." Tamayo answered Tanjiro kindly.
Then Tamayo explained again, for the blood that Tamayo and Yushiro usually consumed. Normally, Tamayo and Yushiro bought blood, through blood transfusions from people who needed money.
Of course, it requires a large amount of blood. But, Tamayo and Yushiro always made sure not to cause any problems for the people they bought blood from.
Finally, Tanjiro understood why their smell was different from the other demons he had met along the way. 'Ah, so that's it.
'Because of this, they don't have a smell like other demons. But, they still need blood, huh?
Secretly, Tanjiro looked at Nezuko who was writhing comfortably on the tatami floor. 'If it's just blood, maybe Nezuko can also...'
Suddenly, Tamayo added that Yushiro was more extraordinary than her because he only needed less blood to survive, since he was the one who turned her into a demon.
Hearing this, Tanjiro was shocked beyond belief. Tanjiro remembered the incident that happened before. The incident where Muzan turned passersby into demons
"Uh so you are? But, eh?" Tanjiro looked confused and panicked about what to answer.
Seeing his surprised reaction, Tamayo told Tanjiro. "Not wrong, Muzan can indeed change people, this is indeed a fact. But, after 200 years, I can turn people into demons. He is Yushiro."
Hearing this, Tanjiro became even more shocked in disbelief. "After 200 years can turn people into demons? Tamayo-san how old are you?"
Hearing Tanjiro question Tamayo's actual age, Yushiro became extremely annoyed and repeatedly stabbed his stomach acupuncture. "Don't ask a girl her age like that, you idiot!"
"Yushiro! I won't forgive you if you do that again." Tamayo gave Yushiro a sharp look, scolding Yushiro's attitude.
Quickly, Yushiro complied. "Yes, Tamayo-sama!" In thought, Yushiro secretly admired Tamayo's beauty. 'Tamayo-sama is very beautiful despite being angry.'
"I hope, you don't take this the wrong way. About this, I don't intend to create more demons. But... For people who are seriously ill or seriously injured. That's all I can give." explained Yamayo.
After that, Tamayo continued. "During that time, I will definitely ask if ican live forever being a demon continuously.
Tanjiro paused for a moment, his nose beginning to sniff out Tamayo's odor. 'She smells like she has nothing to hide. Looks like I'll trust her.'
After hearing about Tamayo's abilities, Tanjiro asked, "Tamayo-san, is there any way to turn a demon back into a human?"
"There is one." Tamayo said this with a sad look and a serious expression.
"Please tell me." Upon hearing this, Tanjiro tried to move closer to receive an answer.
But Yushiro angrily picked him up and turned him over for trying to approach Tamayo. "Don't come near Tamayo-sama!"
Tamayo immediately scolded him again for hurting Tanjiro. "Yushiro..."
"I only pushed his body, not hurt his." Yushiro answered Tamayo who was getting angry.
"Don't do it again!" Tamayo warned one last time.
Tamayo then says that treatments do exist, as they do for any disease, but there is currently no cure. However, Tamayo mentions his desire to do research and create this cure and asks Tanjiro for two things.
First, asking permission to study Nezuko's blood. Secondly the most extremely difficult task to do, collecting the blood of a demon close to Muzan.
The demon blood contained the highest concentration of Muzan's blood, coming from a demon that had a power level similar to Muzan. Or you could say, Tamayo asked Tanjiro to collect one of, perhaps many of Kizuki's 12 demon blood.
"Thank goodness, Nezuko." Tanjiro smiled warmly with a hopeful look of acceptance, grateful for the opportunity to help.
"Nezuko's condition is unique in that she must sleep to heal. That's why, I'll be researching her blood." Tamayo explained.
Because of Nezuko's condition of having to sleep to heal, Tamayo considered it very rare and unique, as most demons could not stand not eating for two years.
Tamayo re-emphasized the explanation that with demons close to Muzan, by which she meant demons similar in strength to her, it made it more difficult.
"Are you still willing to do her seemingly unreasonable request?" Tamayo once again returned to ask Tanjiro with a very dangerous request.
Tanjiro turned his gaze away and looked at Nezuko by his side. "If there is no choice, then I will do it."
"If Tamayo-san can research a certain amount of demon blood to make medicine, then... " Tanjiro looked at Tamayo with a hopeful face. "Not just Nezuko, but many other people's lives are saved, right?"
"Right." Tamayo smiled at Tanjiro's words which seemed to make her heart warm.
Seeing that, Tanjiro's face turned red from blushing, although he immediately saw Yushiro's anger as if he wanted to strangle Tanjiro as soon as possible.
