Natsume Misumi holds the pivotal role of lead miko in the ritual driving the story’s core conflict. A childhood friend of Haruto Okonogi, whose family oversees the 74-year tradition, her unrequited affection for him fuels simmering resentment toward Hisone Amakasu, Haruto’s romantic counterpart. Balancing shrine maiden duties with high school life, she engages in sacred ceremonies determining the ritual’s central figure. Her youth establishes a stark age gap with Haruto and Hisone, both adults enlisted in military service. Childhood flashbacks depict Haruto cradling her as an infant, underscoring their generational divide and intensifying the complexities of her longing. Her dual ties to the ritual and Haruto position her as a catalyst for tension, particularly as she scrutinizes Hisone’s bond with him ahead of the mission’s climax. The story intertwines her unresolved romantic arc with societal contrasts between adolescent vulnerability and the adults’ martial obligations.
