Yuma Mukami, formerly known as Edgar, is the third son of the Mukami household. The voice, body, and attitude of this rebellious do-S 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 extremely perverted and hot-tempered.
As a child, he was timid and shy. However, those traits had to be deserted if he wanted to survive out on the streets with the other members of his rebellion gang. He grew violent, rough, and dominating with time.
