水野 琉夏

A lively girl who has a lot friends and gets along with everybody regardless of their gender. Her hobbies include pretending to be queen, and she loves it when the boys compliment her. Her dream is to become a bitch gal (in other words, a slut). Ruka's favorite foods include hamburgers, and her disliked food is milk, which shows that she's still just a kid. She lives by the words "I wanna have fun", which is why she is almost always out playing with her friends, unlike her kid sister who prefers staying inside and being a bookworm.
