Kurimu is a third-year student and student council president at Hekiyou Academy. She's 148 cm tall, weighs 44 kg, and has distinctive pink-reddish hair. Her blood type is A, and she's known for having an extreme sweet tooth.
Her nickname, Aka-chan, comes from Chizuru and plays on her first name—Kurimuzon (Crimson in English) becomes "Aka" (Red) in Japanese. The nickname doubles as a joke since "aka-chan" also means "baby," which students use to tease her about her small stature and youthful appearance, despite being a senior. She doesn't seem bothered by the teasing when it comes from Chizuru, though.
She's well-liked around campus and has become something of a running gag in the series—most episodes open with her making some kind of announcement in front of a whiteboard. She's also directly responsible for Ken becoming an eroge maniac, which is kind of her fault.
Kurimu and Ken first met in spring when she was vice president. He helped her carry boxes, and when he asked for advice on becoming a better person, she suggested playing a dating sim game. She figured the main character's job was to make everyone happy, so it seemed like good practice. That conversation gave him direction and taught him to think about the future. True to her spring-like nature, Kurimu's always the one pushing new ideas and keeping her eyes on the bigger picture.
