Miho Fujikawa

As the younger cousin of Yamato and Ayano’s daughter, this spirited girl shares a deep, protective bond with her relative. Her intense devotion often manifests as jealousy toward Suzuka, and she frequently teases Yamato by bringing up their childhood marriage promise. After a time skip, she transitioned into a high school track manager and briefly occupied Suzuka's former bedroom, though she eventually moved back in with her mother once Suzuka returned to the apartment complex.
