Innocence. The most powerful trait of a human could have. Especially a child. Those big eyes stared at you with pure intention. Muzan Kibutsuji is a demon and saw (Y/N) a child. It wasn't everyday he would see a child who was lost. My first Reader Insert with interaction of Muzan Kibutsuji!! I don't own the cover photo. I don't own Kimetsu no Yaiba character Muzan Kibutsuji.All Rights Reserved
