Kyuuchi's a vampire who turned 'cold cow' after finding out that human blood tastes yucky. She is completely obsessed with Yosou, and has somehow managed to come to believe he's returning the favour. (He tends to run away from her on sight, but occassionally he puts up with her) She's usually very bouncy, but acts a little sweeter than she really is. She tends to act differently after nightfall. Oh yes, she has a very large wardrobe and has been known to suddenly change clothes during scenes.

Kyuuchi ignores pretty much everything going on around her, and doesn't know what that strange 'Dragonball Z' thing is, because according to her, Yosou's much more interesting.
