you lived with your brother and mother, one day you came home from work, you noticed your own home became a crime scene. You was filled with rage and decided to take revenge on the killer. And you did, very brutal. But right after you was done, Muzan Kabitsiju stood behind you.

Be smiled, almost humane. He walked toward you as you was still holding the knife.

He extended a hand

"Do you want to become a demon?"

He asked, the question sounding unreal.
