One day, a white-haired boy of unknown origins became an honored guest of the Demon Slayer Corps. According to a certain nameless victim, Mr. Demon, the boy's swordsmanship was incredibly skillful. One move was all it took to take him down.
Besides that, he also possessed an extraordinarily powerful supernatural ability. Just how powerful was it? Let me put it this way: according to a certain nameless second victim, Mr. Demon, I was working so hard to bite someone to death, and then he showed up and touched them. The wound I'd finally managed to inflict healed completely. What's more, the members of the Demon Slayer Corps watched with their own eyes as he cured their master of his illness, and the boy himself didn't even think it was a big deal...
Note: The protagonist is in poor health. The reason will be revealed later.
The pairing is undecided, but I'll start writing for now.
Theme: I love Demon Slayer!
