[Amuai Okashi Seisakusho (Ochita Ato Daisuki Samurai, Ahoge Kinoko)] Kyousei Gimukyouiku! TS Ecchi na Onnanoko Kunrenkou! [Raknnkarscans]

Tsukasa, a sixth-grade boy suddenly turned girl, is shipped off to a correctional training academy where the uniform is a school swimsuit and every lesson demands obedience. Caught between a stern instructor's cold commands and a student ID card that still remembers who he used to be, his tears and defiance slowly give way to servitude. By the time the group lessons wrap up with breathless praise for a job well done, the line between punishment and pleasure has all but vanished.
