This is a version of Night, who is not afraid of hurting anyone. He has witnessed murder and done it himself several times.
He fortunately found a habit in casting spells and befriending demons. Interesting enough as it sounds, the various different masks he likes to wear usually has horns attatched to them.

Note: He wears a mask to hide his identity in his world and Outside ones. And yes, he is kinda crazy, but usually mischievous.
