Eles often suspects him of being a former criminal, and Kohaku sometimes shows disdain for women, indicating that they have wronged him in the past. He is also an avid gun enthusiast and always carries weapons with him. Kohaku can use his violin strings and bow as weapons, and he has no qualms about killing Guignols or innocent people.

Kohaku has two different colored eyes and a scar across his face, which he claims was caused by a woman biting him, but it was actually inflicted by Guignols. He experiences pain in his right eye whenever Guignols or infected humans are near.
