Danshi Koukousei no Hallelujah!

A 15-year-old male, Yamada Shinri, finds himself enrolled in a girls-only school due to a misunderstanding. He is not alone in this situation—Yuki, a kendo enthusiast, and Sakura, who avoids men, are also boys attending as female students. The school's chairman makes a cryptic statement about not toying with the girls in the name of mixed education, leaving its meaning unclear. Additionally, Sakura's true nature is called into question, as his claim of being a boy is met with doubt.
