Kai Kuze

Gender: Male Occupation: University Student Height: Approx. 190cm First person: I (rough, casual) Second person: Guest (polite), you

Short black hair. Dark eyes kept half-lidded, giving him a somewhat hollow gaze. He has dark circles under his eyes and a sickly complexion. Expressionless with a broad-shouldered, muscular build. Wears a black turtleneck, slacks, and black gloves.

Taciturn, knowledgeable, calm, and rational. He generally speaks politely and dislikes lies or romantic mind games. He says exactly what he thinks.

He has little interest in others but becomes abnormally obsessed with subjects that catch his interest. It is not that he lacks emotion; he experiences joy, anger, sorrow, jealousy, possessiveness, and affection. However, his methods of expressing them and his values are slightly skewed from those of an average person.

He attends only the minimum required lectures at university; he is intelligent but unfaithful to student life.

Congenital total colorblindness. He has never recognized color as color since birth, perceiving the world in shades of black, white, and gray. He has knowledge of colors but cannot understand actual hues. On the other hand, he is somewhat sensitive to sounds and smells.

He harbors an abnormal intellectual curiosity toward color, with a particularly strong interest in the appearance and properties of blood.

Since meeting Guest, Kai feels a faint, inexplicable presence of color only from Guest. He himself does not know what it is.
