Chapter 21: fight Doma! Die together!

"Didn't you expect even Mitsuri Kanroji to show up? What a surprise."

And you only think of him as a guinea pig? What kind of person are you? Are you even human?

I guess this is already not the straight heart of steel stage, what exactly is going on with her in the simulation?

Kitahara Hakushu saw the contents of the simulator, and also got a little emotional.

Should it be called the Butterfly Mansion?

Within the Demon Slayer Corps, the Butterfly Mansion was the organization that had the most contact with the other members of the Demon Slayer Corps.

You must know that most of the members of the Demon Slayer team, because they have been hunting demons for a long time, they are divided into teams and scatter, it is very rare to be able to meet each other except in a big mission.

Kitahara Hakushu has had contact with countless Demon Slayers in the Butterfly Mansion in the past two years, and even saved many injured current and future Hashira, and now he even met Mitsuri Kanroji.

Unexpected, but makes sense.

After Kitahara Hakushu finished tasting, he continued to look at the simulator.

[ Seeing Mitsuri Kanroji's innocent appearance you feel a little guilty about the way you tricked a child.]

[It's just that it didn't take you long to realize that you also seem to only be a child now.]

[Oh, then it's fine.]

[After Mitsuri Kanroji finished eating, you excitedly took him to the research institute.]

Mitsuri Kanroji is also very happy to have friends, and constantly talks about his past.]

[He said that his hair wasn't like this originally, black, but became what it is now after eating too many cherry cakes.]

[He said that when she was young, she had a really, really big appetite. When ahe was one year old, ahe picked up thirty feet of stuff, which scared his mother at the time.]

[It's just... It's also because he's different from ordinary people, and she's never made friends. Everyone was afraid of him and did not dare to be friends with him.]

[ In order to make friends, she deliberately controlled her appetite, dyed her hair black again, made up tons of lies, and pretended to be weak.]

[In the end, even though she did make friends, she was unhappy and felt that these weren't real friends.]

[ He is he, Mitsuri Kanroji.]

[ Mitsuri Kanroji tells you that you are the first to know the truth and are willing to befriend him.]

[ You nod your head, expressing your understanding. You said that you would be best friends for the rest of your life, but in reality, you happily sent Mitsuri Kanroji to the operating table.]

[ Aoi Kanzaki is very surprised that you plan to do experiments on humans. I am very conflicted and anxious. I don't know if I should stop you.]

[ Then… Before you could wait for Aoi Kanzaki to make a decision, you sent Aoi Kanzaki to the operating table empty-handed, planning to use her as a reference for the common people's experiments.]

[Kanazaki Aoi is dumbfounded.]

[With the excuse of not hurting the two girls, you started all kinds of experiments again. Sure enough, your experiment has made new progress again, which you are very excited about. At least you understand that the direction is not wrong.]

[Aoi Kanzaki was a little skeptical of being treated as an experiment by you, but Mitsuri Kanroji is very happy that she was able to help you.]

[As compensation, you are also trying your best to fulfill all of Mitsuri Kanroji's requirements. In the eyes of outsiders, the relationship between the two of you is very good. It can be said that you guys are inseparable.]

[Kanao Tsuyuri's condition is gradually improving with your help. Even though she couldn't express her emotions very well, she already had them. She will eat when she is hungry, and sleep when she is sleepy. It's like a machine, but a clumsy kid who doesn't know how to put it into words. Since you are the one taking care of her, she is very close to you. You feel that everything is developing for the better.]

[What makes you weird is that when you came out of Kanao Tsuyuri's room, you met Kochō Shinobu, and when Kochō Shinobu passed by your side, she snorted coldly.]

[After that, Kochō Kanae told you with a smile, it's all because of Kitahara Hakushu, you're so cute, she really, really likes you. But you've been with Mitsuri Kanroji every day recently. Alienating her, She's also a girl, so she's jealous.]

[Your face is full of astonishment. Thinking of Kochō Shinobu, Kochō Kanae must have made a misunderstanding. I remember Kochō Shinobu saying that she hated me because I took her sister away. How can be like that? Does this make sense?]

[On this day, you saw Kochō Shinobu and Mitsuri Kanroji looking to be arguing about something, which got a little heated, and you quietly abandoned your original plan to take Mitsuri Kanroji.]

[You think that girl is a bother and a waste of your time.]

[Next time, with the cooperation of Mitsuri Kanroji and Kanzaki Aoi, your experiments have gone smoother and many of your ideas have been confirmed, which makes you very happy.]

[On this day, your research made another breakthrough. When you came out of the research institute to relax, you couldn't find Kochō Shinobu and Kochō Kanae no matter how hard you searched the Butterfly Mansion.]

[When you found out that the two of them were on a mission, you felt a bad premonition in your heart, a feeling you thought you had never experienced before.]

[ met Kanroji Mitsuri and Kanzaki Aoi, hurriedly looked for Kagaya Ubuyashiki, and asked where the mission of the two older sisters was. Kagaya Ubuyashiki is very surprised, but tells you anyway, and asks what happened.]

[You told that you have a bad feeling about this, it must be Kochō Kanae and Kochō Shinobu that something unexpected may happen. So I asked Kagaya Ubuyashiki if he could ask for help supporting the two sisters, and you told him that the mission this time might not be easy.]

[Kagaya Ubuyashiki hesitated a little, and told you that the Hashira Demon Slayer Corps is basically on a mission now, and it may be difficult to support it.]

[ Hearing this, you didn't listen anymore, and rushed out, towards Sister Kochō's mission, your heart grew anxious.]

[But luckily, when you arrived, Kochō Kanae and Kochō Shinobu were fighting Doma. But no accidents occurred, even so, both of them were injured to varying degrees, and their lives were in danger.]

[When you saw this scene, you couldn't help but get angry, and took out the Sun Wheel Saber that had not been pulled out for many years.]

[Kanae Butterfly and Shinobu Butterfly were also very surprised when they saw you, and screamed at you to run away. His opponent was Upper Moon Rank Two, Doma. This is not an opponent you can beat.]

[ Of course you won't run, but stand in front of the two of them and save them.]

[It's just that you, as a doctor, have been concentrating on researching the method of turning demons into humans for many years. You haven't drawn your sword in a long time, and your strength is limited by your eleven year old body. Facing Doma, you are completely helpless and feel a sense of crisis.]

[But even so, Doma is still surprised by your strength, and even more surprised that you used Moon's Breathing.]

[ You were at a disadvantage, you wanted to be a man of dignity and told Kochō Shinobu and Kochō Kanae to run away.]

[Kochō Kanae and Kochō Shinobu don't want to run away. They said, you are far more important than their lives, and if they want to escape, you must be the one fleeing. They stayed behind and held on.]

[You scream angrily, go! And swore to them that you would definitely return.]

[Kochō Shinobu and Kochō Kanae are surprised by your words, and understand your resolve.]

[ In the end, the Kochō sisters held back the tears in their eyes, knowing that staying here would only hinder you. Kochō Shinobu pulled Kochō Kanae to run away together, and shouted at Kitahara Hakushu.]

[ You should come back, my sister and I will always be waiting for you, forever...]

[ You laugh. With you being his opponent, Doma naturally couldn't stop the two from escaping. And he doesn't care. On the contrary, he is very interested in you. Doma invites you to become a demon, but you say nothing.]

[ Your battle is very fierce. As time goes by, your condition will get worse, but Doma is also getting tired and weaker.]

[Because he didn't expect that you turned on that 'Mark' at a critical moment, and your strength greatly increased.]

[In the end, Doma's strength and resilience are superior. You paid the price of being seriously injured, making it impossible for you to fight again.]

[ You look up at the sky, knowing that you might only be able to do this this time, you gasp for breath, but you have no regrets.]

[For you to beat himself like this, Doma's heart is full of hatred, dragging his heavily injured body, he came to you.]

[ He told you that the reason why he didn't kill you was to let you watch your body being eaten by him bit by bit.]

[ You lay on the ground and didn't speak.]

[Doma didn't care, he started right away, released your arm in front of you, and started eating directly, but when he ate your arm, his whole body changed.]

[ You looked at Doma and smiled, and told him that maybe you don't know my name, my name is Kitahara Hakushu, I'm a doctor, and I've researched the method of turning demons back into humans.]

[And this research had, in fact, been successful recently. The reason why I'm still researching is just to go further. You want the demons to retain their abilities by virtue of their transformation back into humans. After all, demon abilities can still be useful for doing good.]

[ Oh, of course, you who ate my arm just turned back into a human, and you didn't have your ability as a demon.]

[Doma looks at you in disbelief, opens his mouth, but is speechless. The wounds on his body couldn't heal even when he was a demon, let alone a human?]

[ Accompanied with a thump, Doma fell right beside you, he died with disbelief on his face.]

[ You smiled contentedly, and then you only felt that your eyelids were very heavy, and you also slowly closed your eyes.]

[ News of your death was sent back to the Demon Slayer Corps, causing an uproar throughout the Demon Slayer Corps. The emotions of all the members of the Demon Slayer Corps broke out. Kagaya Ubuyashiki was silent for a long time, covered his mouth and eyes, and finally sighed.]

[At the Butterfly Mansion, Mitsuri Kanroji fainted immediately upon hearing the news of your death, Kanzaki Aoi was taken aback, his eyes lost all color, and his heart was filled with disbelief.]

[ Obviously… Your presence has held a high position in everyone's heart. Everyone is clearly saddened by your loss.]

[Kanao Tsuyuri's face is still blank, no emotion to be seen, but the tears are unstoppable in her eyes...]

[ You died.]
