is a senior in Hekiyou Academy, and is the president of the student council. She has an extreme sweet tooth, and has a pink/reddish hair. Her nickname is Aka-chan, which was given to her by Chizuru; She added an extra character to her first name, and changed it to Kurimuzon and translated to Japanese becomes Aka. Her nickname can also mean Aka-chan. This is often used as a joke against her in the series, poking fun of her childish size and looks, despite being a senior. However, acting childish around Chizuru does not seem to bother her. She is well-liked by most of the other students. Most of the episodes start out with Kurimu making a statement in front of a whiteboard. She is the cause of most of Ken's labor and why he became a eroge mania. Kurimu and Ken met in the spring when she was Vice President at the time, Ken decided to help her carry boxes. He asked for her help in becoming a better person, and Kurimu suggested playing a dating sim game as she said that the main character's job is to make everyone happy. Their meeting gave him a goal in mind and taught him to look towards the future. Like the season she represents, she's often the first to suggest something and is always looking towards the bigger picture in mind.
