The cheerful, outgoing title character of the series, she becomes the student council president from her campaign to spread love over the school, passing out condoms in the process. She moves in to Hayato's apartment as his fiancee in an arranged marriage. She is noticeably less serious at "home", slacking off and acting like a dependent, the opposite of a leader, with baby chicks appearing atop her head. Throughout the series she tries to please Hayato romantically and even sexually, knowing very little about how to do so.
