Dear Brother

Sixteen-year-old Nanako Misonoo enrolls at the prestigious Seiran Academy, an all-girls school, expecting a promising future. Instead, she finds herself trapped in a world of lies, suffering, and envy. To make matters worse, she’s selected to join the Sorority, an elite group admired by the entire student body. Lacking the poise, wealth, or skill of the other members, Nanako becomes a target for her resentful classmates-particularly the ruthless Aya Misaki. Struggling with the harsh realities of school life, Nanako turns to letters addressed to her former teacher, Takehiko Henmi, whom she fondly calls "onii-sama." She also leans on her closest friends: childhood companion Tomoko Arikura, the lively but unpredictable Mariko Shinobu, troubled musician Rei Asaka, and sporty tomboy Kaoru Orihara. A raw and emotional story about the pain of bullying, "Oniisama e..." follows Nanako as she faces vicious rumors, merciless peers, and the relentless challenges of her new environment.
