[Old Apple] Shirasu Azusa

Azusa Shirasu is a quiet, aloof student at Trinity General School, secretly raised as a child soldier for the rival Arius Branch School. Sent as a spy to sabotage Trinity, she instead finds herself drawn into the Supplementary Lesson Department, slowly learning to enjoy ordinary school life and cute things like the Momo Friends mascots. Despite her awkwardness and fear of burdening others, she fights with exceptional guerrilla tactics to protect her newfound friends—even as her past threatens to destroy everything she’s come to care about.
