Enkougawa, Ruzaburou

猿猴川流三郎

Rusaburou Enkougawa (猿猴川流三郎, Enkōgawa Rusaburō), commonly known as Enryuu (猿龍, Enryū), is an anime-exclusive character introduced during the Kasumiouji Conspiracy.
Outline:
He is a silent, heavily built man with a small mohawk shaped like a lightning bolt. He wears a light undergarment beneath his Shinigami uniform, along with a pair of sunglasses. Based on the opening credits, it appears that he possesses superhuman strength. Like Kenryuu, he serves Rurichiyo Kasumiouji. He takes it upon himself to punish anyone he perceives as being rude to their princess. It was possible that he is mute, since he has never been shown speaking, even when asking Kenryuu about Rurichiyo's location (he uses comical gestures to ask, which Kenryuu understands) or when releasing his zanpakutou. However, during Amagai's attack on Yamamoto, he is heard to have a highly squeaky voice, and his blush makes it clear that he is self-conscious about it.
