Mayuko appears as a column of long black hair with numerous twisted, smiling faces peeking out between her locks.
Mayuko holds nothing but contempt for other women, responding primarily with hateful words. Whether her phrases are directed, or just general, is unclear, as she tends to vary between responding to the situation and throwing out random insults.
A Demon who inhabited the northern restroom on the sixth floor of the girl's dorm, Mayuko was formed from the cruel thoughts of women and only appeared before girls. Becoming one of the Seven Mysteries of True Cross Academy, she came to the attention of the Cram School after attacking a group of Third Year girls who entered the bathroom as a test of courage.
