Dear Brother

Sixteen-year-old Nanako Misonoo arrives at the elite Seiran Academy expecting a fresh start, only to be pulled into a tense world of status games, envy, and quiet cruelty. Her troubles deepen when she’s selected for the Sorority, a celebrated inner circle that fascinates the student body. Lacking the poise, privilege, and polish associated with its members, Nanako becomes an easy target—drawing particular hostility from the sharp-tongued Aya Misaki.

As school life grows more isolating, Nanako records her days in letters to her former teacher, Takehiko Henmi, whom she calls “onii-sama.” Support comes from a small group of friends: her longtime companion Tomoko Arikura, the outgoing yet unpredictable Mariko Shinobu, the troubled musician Rei Asaka, and the sporty, boyish Kaoru Orihara. *Dear Brother* follows Nanako through rumor, jealousy, and bullying, painting an intimate portrait of adolescence under pressure.
