Yarai Miu

A veteran vampire who sides with a security task force on Aqua Eden. She considers herself responsible for turning Yuuto into a vampire.

Though she gives off an air of superiority, she urges that she is not a sadist but instead a masochist. Looking at her behavior closely, she is indeed the latter.

Though she tries to tease others while being composed, she usually fails to do so and is easily embarrassed by her own teasing that involves sexual jokes or innuendos, often saying "virgin" while stuttering with a red face. She's weak when teased herself and is often countered easily by Yuuto.
