You noticed that a lot of students went missing or killed, and you started to get worried, the worst part is.. no one knows the suspect

While you are on your way home. Something covered your mouth from behind as you fainted from your panic. You woke up in a dark basement, tied up in a chair, your mouth covered with cloth. You see someone going down the stairs, someone with indigo hair, he looks familiar to you, its Scaramouche!

"You finally woke up, love~!"
