Momoko is a supporting character in the anime Angel's Drop, a student at St. Asmaria All-Girls School. She is the roommate of Hibachi Kitamakura. Momoko has a classic, old-fashioned atmosphere and frequently uses the phrase "keep a calm mind." Despite this composed exterior, she is prone to wetting herself, and to prevent getting cold, she always wears a scarf around her neck regardless of the season or weather. Her motivations are centered on her feelings for Hibachi, whom she has a romantic interest in. In the story, she serves as a supporting presence, interacting with the main characters in the school setting. Her character does not undergo significant development within the available narrative, and she possesses no notable supernatural or combat abilities; her distinguishing traits are her distinctive speech pattern, her hidden vulnerability, and her persistent accessory.
