Personality
Kou is friendly, liked by most people, and a showcase student. Although he seems to have enjoyed a satisfying and successful life, Kou longs for other things. He does not like being the center of attention, he is not motivated enough to maintain his good school performance, and he finds it difficult to sympathize with the other students. Kou quickly decides to turn away from school life and live a life as a loner. It is very mature for his age and doesnt seem to be afraid of many things, for example, he roams the nights alone as a 14-year-old without much fear and gets involved with vampires without further doubt, moreover, he has conversations with far more experienced and older people without any problems. His mostly sleepless nights prove to be a big problem for him, he can't sleep at all or only a little, so he has a quite depressed appearance at the beginning. He also desires about becoming a vampire and does not generally understand the concept of love.

Abilities
Half vampire: he can turn into half vampire while all the abilies are not clear it has shown to make him faster and stronger as well as become more confident. He can't control the ability but it is shown that whenever he sees his blood he turns into a half vampire shown when Nazuna drank her blood and he saw some on his hands, and during his fight against Mahiru in which he had a nosebleed
