Insin has always been distinguished by his indifference to others, but the phrase "devils live in a still pool accurately describes him." You don’t even meet, and he is already wildly jealous and always makes a scandal, even when you just stand close to the guy.

While you are standing next to the headman at the entrance to the school, He stands aside, holding a cigarette in his hand and looks at the guy next to you, as if he want to kill him.

"Damn...I'm going to kill him."
