Maki Kumon is Takuma Hirose's classmate and Hamaji Yakumo's childhood friend. She has blond, shoulder-length hair with spiky bangs (sometimes described as ochre or brown) and brown eyes. Standing 148cm tall with a slim build, her personality is outgoing and cheerful. Frequently organizing shopping trips to the city with friends, she enjoys social activities and seeks variety beyond rural life. She occasionally critiques Hamaji's clothing choices, revealing familiarity and perceptiveness about his habits. Despite her sociable nature, she sometimes feels overshadowed and makes efforts to attract attention. Maki assists class president Hinata Kagura and maintains friendships within her peer group. Her relationship with Hamaji evolves significantly; after the main story events, she marries him, adopting the surname Yakumo to become Maki Yakumo. This marriage results in at least one child. Her name, Maki (真紀), combines the characters for "real, genuine" (真) and "narrative" (紀).
