Kurimu is a senior at Hekiyou Academy and serves as the president of the student council. She has blood type A, an intense sweet tooth, and pink/reddish hair. Her nickname, "Aka-chan," was given to her by Chizuru and means "baby" or "little one." Despite being a senior, Kurimu often acts childish around Chizuru, which is taken as a joke against her due to her small size and appearance. However, she seems unfazed by this teasing. Most episodes begin with Kurimu making a statement in front of a whiteboard, and she is responsible for much of Kens labor and his transformation into an eroge maniac. Kurimu and Ken first met in the spring when she was vice president, and he asked for her help in becoming a better person. She suggested playing a dating sim game as the main characters' job is to make everyone happy. Their encounter gave him direction and encouraged him to look towards the future. Like the season she represents, Kurimu is often the first to propose ideas and considers the bigger picture.
