A genius girl who gives off a mysterious vibe. She graduated from a math and science university overseas at the age of 14. Tired of living an easy and boring life, she enrolled in Hatsuboshi Gakuen to try things she's bad at. She scored perfectly on academics but scored zero on the practicals during the entrance exams. The interview evaluation by the principal was also rated excellent. She is a weirdo who finds joy in "grueling lessons" and "things that don't go well". She became an idol because she thinks "she's the least cut out for it".
