Shizuku is a Mizuchi (Water dragon demon) in the form of a green, short-haired small girl with snake tongue that can stretch rather far, similar to that of a chameleon, and can breath underwater. Shizuku usually has a stoic expression, and is almost always completely soaked with water. She first meets Yūto at a river, where she warns Yūto that if he continues to go along with his demon slayer heritage, she would kill him. To make sure of this she invites herself to live in Yuto&#039;s house and starts to like him romantically. 

Yuuto Amakawa’s life becomes pawsitively arousing when beautiful demons start showing up! But with beauty comes danger. With cat demon Himari Noihara sticking by his side, he’ll have to face the deadly Ayakashi—demons seeking revenge on demon slayers. Between this, the cat girl, water deities, and demons galore, he’ll have to do all he can to stay abreast of everything happening around him! <br><br>

Released her first single "Jump up!" on August 24, 2005.

Severely allergic to felines, Yuuto Amakawa spends his mornings nursing a drippy nose courtesy of his friend Rinko’s cat. But on his sixteenth birthday, it’s not just Rinko’s pet that’s riling up his allergies (to say nothing of his hormones)! Appearing before him is Himari, a buxom, sword-wielding cat spirit in human guise, who has sworn to protect Yuuto, now the target of vengeful spirits! It’s clear that Yuuto’s allergies are the least of his problems — he’s gonna need Himari’s help if he wants to live to see his seventeenth birthday!<br><br>
