Sumika Kagami

An energetic and clumsy classmate of Takeru, this bubbly girl shares a deep, lifelong bond with her childhood neighbor. While she has long cherished their shared memories and secretly harbored romantic feelings, the arrival of Meiya sparks a fierce, possessive determination to evolve beyond a mere friend. Though she remains an optimistic advocate for teamwork and loyalty, her intense devotion to Takeru often drives her to protect their bond at all costs.
