Originally a member of the Justice Actualization Committee, she was forcefully transferred to the Supplemental Lessons Club due to her falling grades and being made to repeat a year.
While she may consider herself elite, she is actually rather stupid, so much so in fact that she is completely unable to keep up with her lessons.
She has a secret hobby(?) of collecting lewd magazines, and experiences delusions about the most trivial things in everyday life, often to her own embarrassment.
