A gothic lolita. She designs her own clothes and she came to El liston since she hated having to wear the same thing everyday and when she wore one of her gothic lolita clothes to school she was shunned by everybody else. She becomes really good friends with Keito. She fell in love with a guy named Yamaguchi, but when she confessed Yamaguchi told her to put on some decent clothes and confess again later. 

When Momiji showed off her sketches to Rei and Kouichi they kindly complimented her and said that they don't know anything about fashion, however Keito sincerely complimented her which started their friendship. She spends much of her time sewing and sketching outrageous outfits with the assistance of Keito.
