Mukami Yuuma

Yuma is the third son of the Mukami household. The voice, body, and attitude of this rebellious sadist are all big. He often goes on rampages, but he falls asleep after he becomes bored. He can always be found munching noisily on sugar cubes. He is very sadistic and rough and also quite perverted and hot-tempered. He doesn't mind consuming the complete body of his victim alongside draining the blood, and this was suggested as the main reason for his physical strength growing even above the average impure vampire.

As a child, he was very lively and cheery. Sometimes too rebellious to his parents who were religious people while he didn't believe in God. After the incident and his amnesia, he had to become even tougher if wanted to survive out on the streets with the other members of his rebellion gang. He grew violent, rough, and dominating with time.

After his parents died in a fire, Yuma became a follower of a street gang and looked up to the leader, or boss, Lucks. Under a new name, Bear, Yuma lived on the streets with Lucks and the others. Lucks would scavenge around and steal food to give to all his followers. He also worked as a slave, or what he claims as "livestock", in order to get money to pay for food as well. His main dream, which Bear would inherit, was to have a world where everyone is free and equal, no social classes or gaps. He wanted to strip the corrupt politicians and aristocrats of their status in order to purify this world of its filth.
