The Doctor's Opinion(Tanjiro's POV)

The owner of the noodle store yelled at Nezuko, 'Seriously! What I want to say was this! It's not about money! If you don't eat the udon I made, I'll never forgive you!' She just stared at the owner confusedly.

He continue saying, 'Hold the chopsticks! What is with this bamboo? Take out that bamboo in your mouth first!' I suddenly appear behind the owner and grab the chopsticks in his hand. I begin to eat his udon quickly.

When I'm finished, I waved goodbye to the owner, 'I'm full now! That was delicious!'

He replies, 'As long as you understand! As long as you understand!' I grab her hands and left the noodle stall.

I apologise to her, 'I'm so sorry Nezuko. I left you on the side.' Suddenly she stopped, her expression changes from calm to alert. I look at where she is looking and notice it was the same boy I met while I am holding down a demon.

I say to him, 'Are you waiting for me? You know I can find you guys by following your scent, right.'

He replies, 'How would you be able to find me? That place has a cloaking spell cast upon it to mask it from other people's sight. Compared to that isn't the woman a demon? And she's a brute of a woman too.'

I frozed for a while and wait for my brain to process the information, 'Brute...Brute? Does he mean brutish woman or something like that? Who's he talking about?'

I turn my head to Nezuko and suddenly realised something, 'Nezuko? Is he talking about Nezuko? Ah! He is talking about Nezuko!'

I talk back to him, 'How is she a brute! Look closely at her feature! Everybody stated that Nezuko is a beauty in our town! How can she be a brute!'

He ignored me and says, 'Lets get going...' while walking away from me.

I continue saying, 'No wait! We can go but you said brute so we're definitely not okay with this! I'll bring you to a brighter place so you can have a better look! That place over there!' while pointing at her. We walk to an alley and suddenly stop right infront of a wall. He walk through the wall and I am quite shocked.

I say, 'Hello? Where are you?' Suddenly his head pop out from the wall and replied, 'Just go through the wall and shut your blabbing about how beautiful is her.' He go back into the wall and I follow him through the wall. I begin to continue convincing him that Nezuko is beautiful until we arrived at a two storey house. He opens the door and greeted the demon girl that I met at the street back then, 'I'm back.'

She replies, 'Welcome back.' while sitting beside a unconcious woman who is bitten by her demon husband.

When I saw her, I ask, 'Ah, is she alright? I'm so sorry leaving her to you.'

She answers, 'She's fine now. Her husband... He's a different case. He's held in the dungeon right now.'

I say in a concerned voice, 'Does it feel uncomfortable handeling the wound of a human?'

Suddenly the boy hit me in the chest and replies, 'As demons, we must endure the saliva bought on by the smell of flesh and blood and you want use us to treat humans as well?' with a irritated voice.

The girl says in a soft voice to him, 'Stop. Why must you resort to violence.' She turn around toward me and says, 'I haven't introduced myself yet. My name is Tamayo and this child is Yushiro. Please try to get along with him.' I look at him but he keep giving out a annoyed vibe. He's so hard to get along with but I really can't do anything about that.

Tamayo continue her conversation, 'And to answer your question, it does not feel particularly uncomfortable. I have an easier time with it compared to normal demons. I am able to manipulate my body to my own whim which made it possible for me to remove Kibutsuji's curse as well.' A curse? So every human will have the curse when they are transformed into a demon?

I confusedly ask, 'Mani... Manipulate body?'

She answers, 'It means that I can survive even without partaking human flesh. All I need is to drink a small amount of human blood, that's all.'

I put down the box I am carry whlie saying, 'Drink blood? That's...'

She replies, 'Maybe it might make you feel unhappy about it, we buy the blood that was originally given for transfusions from people who don't have a lot of money. Of course, all we really need is an amount of blood. That won't cause any disturbance to the person.' I see so is this the reason why these people don't have on them the stink that only demons possess? But apparently they still need human blood... If only blood is required then maybe Nezuko can...

She continue saying, 'Yushiro is even more impressive as he only needs a minuscule amount of blood to survive. I was the one that transformed him into a demon.'

I suddenly widen my eyes in shocked, 'Eh? It was you?! But... Eh?'

She answers, 'Indeed. People other than Kibutsuji are unable to increase the amount of demons. This is factually correct. However, after going through 200 years, the only person that was able to transform into a demon was Yushiro.'

I yell in amazement, 'The only person that was able to transform into a demon after going through over 200 years is Yushiro! Tamayo-san, exactly how old are you!'

Yushiro suddenly chokes my neck, 'Don't just ask a lady for her age like that! You uncouth ruffian!'

She yell at him, 'Yushiro! I'm not going to forgive you if you hit him again!' He suddenly stop hitting me and immediately switch to obedient mode, 'Understood!'

She turn toward me and says, 'I hope that you don't misunderstand this one thing. I won't increase the number of demons but to a person that is plauged by a disease without cure and is about to die, this is the only option I can offer them. During that moment, I will definitely ask that person if they want to continue living forever as a demon before continuing.' I smell her scent and her scent tells me she isn't hiding anything and is a bit fresh too. I might be able to trust her if it's this person.

I asked her a question, 'Tamayo-san. Is there a way to turn a human turned demon back into a human?'

Outside the house's clocking spell area...

Two figure was walking down an alley. The two of them were demons. One of them which is a boy with eyes on his hands trying to find our location. The other demons which it is a girl says, 'Can you see it?'

He replies, 'I see it. I see footprints. He turned around there and circled a long way around. And then there were three people with a huge box.'

She says, 'How do we kill them Ufufufu. I feel this power coursing through me because we received the blood from the great one just now.'

He answers, 'Well, of course we are going to slaughter him as cruelly as possible.'

Back to Tanjiro...

'A way of turning a demon back into a human. There is one.' Tamayo said.

I suddenly get close to her and yell, 'Please tell me the...!' I was suddenly pushed back by Yushiro, 'Don't get too close to Tamayo-sama!'

She look at him and say in a angry tone, '...Yushiro... Why are you hitting him again...'

He quickly switch back to obedient mode and says, 'I only just threw him out, Tamayo-sama. I wasn't hitting him.'

She replies, 'Please don't do either of those things.'

She continue saying to me, 'However, at my current state, I can't turn demon back into a human. No matter what kind of sickness it is, there will be always a treatment methods and medicine for it but I will do my best to research and develop a method of treatment. To make the medicine for treatment, there is a need to investigate a large amount of demon blood. I have two things I need to ask of you. First, I want to investigate your sister's blood. Second, do your best to gather as much blood from demons with Kibutsuji's blood coursing through their veins. Nezuko is currently at a very rare and very precarious stage of development. This change probably occured during those two years that she jas been asleep which you told me about. Normally, if a demon hasn't eaten the flesh and blood of a human or beast for such a long time...There is no doubt that it will go berserk. However, the most suprising thing is that Nezuko doesn't have any of those symptoms right now. This miracle might become the key to unlocking this mystery int he future.' I put my hand on Nezuko head and she grab my hand and plays with it.

She continue saying, 'The second thing I want from you is a very cruel one. The demons with thick Kibutsuji blood coursing in them are demons that have gained a massive amount of strength from Kibutsuji himself. It won't be an easy task robbing these demons of their blood. Even so, are you willing to accept my request?'

I look at Nezuko and reply, 'If there is no other option for me to take then I will go do it. If Tamayo-san is able to investigate a large amount of demons blood to create and manufacture medicine then not just the life of Nezuko, the lives of even more people will be saved, right?' with a optimistic tone.

She replies, 'Yes, Tanjiro.'

Suddenly I felt a tremor outside the house. Yushiro suddenly shouted, 'Get DOWN! Everyone!' He pull Tamayo down onto the ground and I also do the same to Nezuko. There is a handball suddenly broke into the house. It bounced around the house uncontrollablly destroying everything in the house.
