Kokomi Asahina is a character from Battle Girl High School. She is a third-year junior high school student who lives and works at her family's shrine as a miko, and her family shrine is frequently visited by her fellow Star Guardians. She is a member of the school's astronomical club, a subject she is deeply passionate about; when speaking about stars and space, she overcomes her usual shyness and expresses herself with clarity and enthusiasm. An encounter in her childhood, during which she heard a mysterious voice telling her to protect the stars, firmly established her dedication to the role of a Star Guardian, which she sees as a divine mission that she must never abandon. Kokomi is characterized by her gentleness and acute timidity. She speaks in a quiet voice and is prone to crying whenever she becomes flustered. A specific form of anxiety she deals with is androphobia, making it difficult for her to talk to men other than her father. She is acutely aware of her own timidity and wishes to overcome it, making vows to become braver whenever she sees a shooting star and attempting to confront her fears directly, such as by trying to watch horror movies. She manages her stress by screaming into a pillow. Despite her shyness, she possesses a very kind heart and is a dedicated and hardworking individual. She is also known to be quite clumsy with luck, famously only ever drawing great misfortune slips from omikuji. As a Star Guardian, she fights using the Leviathan star dress and is associated with the Sirius and Pixie units. In the story, she is a supporting character whose growth involves learning to balance her self-doubt with her strong sense of duty to protect others. Her relationships with the other Hoshimori are important to her development, as they offer her support and encouragement. She is motivated by the childhood voice and her personal desire to be of use, pushing her to fight despite her natural inclination to shrink away from conflict. In addition to her combat abilities, Kokomi is a skilled cook and a musician who enjoys playing the guitar and writing songs. She has dark brown hair and blue eyes, is 154 centimeters tall and weighs 44 kilograms, and was born on October 2nd with blood type A.
