From All Stars: A third-year at Nijigasaki High School. She has looks and proportions unlike any high school student and has been an amateur model before. Karin is surprisingly stubborn in contrast to her mature appearance. She hasn't taken much seriously until now, but ever since becoming a school idol on a whim, she's really gotten into it.

Background:

Karin wanted to become a school idol to boost her self-confidence. Along with Kasumi Nakasu and Setsuna Yuki, she works with Dengeki Online.

In the Nijigasaki dorms, she shares a room with Emma Verde.

Personality:

Karin is very mature and gives off a rather seductive vibe. She uses her adult-like looks to her advantage, such as when she tries to tease her underclassmen. She also teaches others how to be sexy and cool like her. However, these lessons sometimes backfire when people begin to show her significant attention or respond in a pure manner, as Karin will become embarrassed. Despite her teasing attitude, she is rather innocent and has a somewhat naive side to her personality.

In the anime, however, her personality is different, being noticeably more reserved and shy. She states she doesn't like being around many people, and used to be a little bit aloof at the beginning of the first season, but nevertheless is genuinely kind and friendly. She is shown to be rather self-conscious about her weaknesses and initially being a loner, and can be naive and clumsy.

Sometimes, Karin is a little bit more childish and nervous than usual, which she dislikes, but she manages to keep up her cool demeanor most of the time. While she is quite confident and likes to compete, she's also a genuinely supportive and empathetic person, as shown when she interacts with Ai's friend Misato and when she worries about her.

Because of her modeling activities taking up most of her time, her grades are below average and she has difficulties waking up in the morning. She is helped at studying by Mia later on, while Shizuku helps Kasumi.

Clubs and Hobbies:

Karin's strength is dancing, and thus she takes the role of choreographer in the club. Outside of the school idol club, she works as a model for magazines. She has enrolled in a design course at Nijigasaki Academy.

Her favorite classes are science and cooking, but she dislikes geography. As revealed in ALL STARS, she actually has bad grades.

Appearance:

Karin is tall with a slim yet curvaceous figure and short navy blue hair that reaches her shoulders and bright blue eyes. She has three aligned beauty marks on the left side of her chest.
