Kana Tatebayashi

Kana Tatebayashi is a 5 years old half-mermaid half-vampire yōkai living in Sakurashin Town. She is the twin sister of Mina Tatebayashi and their guardian is Shidō Mizuki. Unlike her twin Mina, her blood is closer to a vampire's, and her body grows into a teenager size (with huge boobs, unlike Mina) if she drinks blood. Another difference is that she is soft-spoken and is always apologetic for Mina's rudeness.
