 Momoko is a fundamentalist evangelical Christian, possibly Pentecostal. Many of her lines contain references to God or Jesus. She also sometimes speaks disparagingly of Jews, Muslims and homosexuals. However, aside from her attempts to indoctrinate Keiichirou and her occasional reminders about spiritual damnation, Momoko is still otherwise perfectly polite and courteous to her "heathen" friends. She reveals that before her conversion, she was a drug-addicted slut but went to Christian Rehab.
