Kuro

クロ

Kuro is a servant vampire, or servamp, who made a contract with Shirota Mahiru. He can turn into a cat in the daylight, and is the oldest brother of the seven vampire brothers. He has a very lazy nature and spends most of his days sleeping, befitting his position as the Servamp of Sloth. Kuro's past is quite mysterious and little known, as he himself prefers to bury some of his memories. However, one thing is certain: in the past there was a fairly serious conflict that made the Servamp of Greed, Lawless, hold a grudge against him.
