On their first day of high school, shy Ayumi Nonomura and taciturn Tatsuki Iizuka get lost on the vast campus of Kamizono Academy. Torako Kageyama, an irresistible force of nature, appears before them alongside her best friend Suzume Saotome. Guided, and occasionally pushed, by Torako, the girls and their classmates navigate the challenges of school, home, and adolescence.
