(UNDER EDITING) L/n Y/n, a sixteen year old teenager from his own world just miraculously appeared in his favorite anime show, Demon Slayer. He ventures with Tanjiro, Nezuko, Zenitsu and Inosuke in order to defeat Kibutsuji Muzan. While in doing so, a twist came up and it turns out that Y/n is actually sharing a seat with one of the Twelve Kizukis-Upper Moon Two. "Finish the mission and go back to the world you once came from! No matter what will happen, keep going and don't ever give up!" (May contain fluff or whatever.) Disclaimer: Anime and Characters ain't mine. Also, I don't own the media I use.
