Shiritsu Hamanasu Chuukoutou Gakkou Danshiryou no Tomadoi

Yuki Yasaka, 14 years old. She is a girl at Hamanasu Junior High, an all-boys boarding school. Her life at the boys' school, filled with men who move with their instincts, is far more crazy than Yasaka ever imagined! The only person who knows Yasaka's secret that she is a woman is her classmate Shiraishi, and their confused days continue. A new kind of coming-of-age gag! (Source: Kadokawa, translated)
