Being the Servamp of Sloth, Kuro spends his time sleeping, lazing around or playing video games. He feels no shame in running away to avoid any trouble and refuses to make decisions, since he doesn't want anything to be his fault, and doesn't want to disappoint anyone. Kuro is a 'shut in' pacifist vampire, and rarely drinks Mahiru's blood, most of the time he refuses and drinks only when he is about to fight. Kuro can also turn into a black cat. Kuro is also 18 years old in human years.
