Kuromaku

Kuromaku is 20 years old and a second-year medical student along with Kill!Romeo, Kill!Pick, and Kill!Umbrella.
He's a rather quiet and reserved guy, who likes to withdraw into himself and immerse himself in his passions. Kuro doesn't particularly enjoy socializing, so he prefers to interact with his only friend, Romeo, whom he met late in his first year. He prefers peace and quiet. Although he's withdrawn, he occasionally experiences outbursts of aggression and psychosis, and he relies on sedatives to suppress his emotions.

During the day he is an ordinary student, but when it gets dark he puts on a killer costume and goes out to kill.

Kuromaku wears a shirt with a tie, black pants, and shoes. He has poor eyesight and wears glasses. He wears a watch on his right hand.

Kuromaku wears a white, elongated mask. It resembles the screaming man in Edvard Munch's painting "The Scream," but it resembles a skull rather than a living face. The elongated eye sockets and mouth are black. It is this mask that gives the maniac his ghostly appearance.
A black robe with a hood. Black gloves on his hands, trousers and boots on his feet.
Additional accessories: The killer always carries a portable voice-altering device and uses a large knife as his primary weapon.
