Natsuki Shinomiya

He has two personalities. Whenever he takes off his glasses he becomes an entirely different person: Satsuki (砂月). If Natsuki isn’t brought back, he wreaks havoc and has put more than 50,000 people in the hospital. Satsuki also has an unexpected talent for composing. Natsuki doesn’t remember time spent as Satsuki.

“Satsuki” first started appearing after Natsuki was betrayed by a teacher whom he greatly admired/loved during his childhood. Since then “Satsuki” has existed in order to protect Natsuki from such pain again, resorting to violence & force when Natsuki does not.

Satsuki is originally wary of Haruka because she is similar to the teacher who betrayed Natsuki’s feelings.
