No one can touch her… The cutest, most aloof girl in the class has lost her memory and her rationality has vanished!? A morally bankrupt girl who crawls on all fours in public places and schools, exposing her buttocks and anus… indiscriminately urinating! Aizawa Miyu CAWD-999

The talented and beautiful student, Aizawa Miyu, lost both her parents in an unexpected accident. Seeing their horribly mutilated state severely traumatized her, causing her to lose all her memories up to this point, and her cognitive functions regressed to a preschool level. Yes, it's 'preschool regression'. Although I knew the term, I never imagined I'd witness it firsthand. Since she has no family, I, her homeroom teacher, am temporarily taking care of her. She's completely unlike her former model student self; she crawls around with her buttocks exposed, moving erratically, and leaking urine everywhere. Although I knew it was absolutely wrong, faced with that adorable face and alluring buttocks, my rationality crumbled quickly. Faced with this unprecedentedly immoral sexual intercourse, my hips simply wouldn't stop.
