Dear Brother

Misonoo Nanako, the daughter of a professor, eagerly anticipates her first day at Seiran Academy, an elite girls' school for the wealthy-or, in her case, those with exceptional academic scores. She quickly discovers the school is divided by the influence of three revered and gifted students, known as the Magnificent Three. While Nanako hopes to avoid trouble, her unexpected selection to join the Sorority drags her into the ruthless power struggles hidden beneath the school’s polished facade. Soon, she can no longer distinguish friend from foe, or even her own sense of self. Her only outlet is the letters she writes to a mysterious figure she addresses as her "Dear Brother."
