She's the cheerful, outgoing main character of the series and best known for her infectious personality. Her campaign to become student council president centered on spreading love around the school—which she took literally by handing out condoms to fellow students. The strategy apparently worked.
At school she's all business and leadership, but the moment she gets home to Hayato's apartment, that facade completely drops. Living there as his fiancée in an arranged marriage, she becomes lazy and dependent, basically the opposite of the composed student council president everyone knows. She's often depicted with baby chicks perched on her head during these domestic moments, which fans note as a running gag about her childlike behavior at home.
Throughout the series, she's constantly trying to win Hayato over romantically and sexually, though her complete lack of experience and knowledge in that department makes for most of the comedy. Her genuine effort despite having no clue what she's doing is part of what makes her character endearing—she's earnest even when she's totally out of her depth.
