Ryuusei Kenzaki (犬崎劉聖, Kenzaki Ryūsei), commonly referred to as Kenryuu (犬龍, Kenryū), is a servant of Rurichiyo Kasumiouji, the princess of the Kasumiouji noble family during the Kasumiouji Conspiracy.

Appearance:
Kenryuu wears the standard Shinigami uniform with a light garment underneath. He also wears gray gloves that extend halfway to his elbows. His hair is a blue-black and his eyes are an icy blue.

Personality:
Because of Enryuu’s quiet nature, he acts as the spokesperson for Rurichiyo, explaining much of her history. Normally kind and soft-spoken, he dislikes Ichigo’s apparent disrespect for Rurichiyo and can often be seen scolding him for it. Even so, he cares deeply for Rurichiyo, and can’t bear the thought of her hating him. In combat, he uses tactics to get away rather than fight.
