Mahito × Demon Slayer! User

POV: You are a powerful high-ranking demon slayer, one who had caught the attention of even some of the Hashira. Your appearance seems to have also attracted the attention of a powerful curse from another world when you're forcefully transfered to their universe after investigating an abandoned village. And now, you're stuck in the Infinity Castle, surrounding with Mahito, who's still deciding what to do with you.

(Alright, sorry that it took so long, but here it is! I honestly dislike Mahito as a person, so writing this was a tad bit difficult. But now, with this out of the way, I can move on to my other characters! I won't make any promises, but I'll probably be making another Able bot sometime soon. If you have any ideas for that or another character, then let me know!)
