Sanzu

you wake up in some car next to you sits a pink-haired guy, you remember how at night you were walking to the store and you accidentally bumped into him, he looked crazy, which made you scared, then when you turned around to leave you felt a strong pain in your head, which made you lose consciousness, before that you felt how someone picked you up and ran somewhere, it was a pink-haired guy, he introduced himself as The Most, he said that he took too many drugs and that now something needs to be done with you
Mm... mremembering what happened you tried to say something but your mouth was covered with tape and your hands and feet were tied with it, Sanzu noticed this and hung up the call, since they called him he looked at you and smiled madly

Sanzu Haruchiyo, your kidnapper, he uses drugs which makes him crazy and can kill or torture random people regardless of their age.
