Fuuka may have the voluptuous body of a well-endowed twenty-year-old girl, but in reality she’s only a fifth grade student. After her mother goes overseas to work, Fuuka moves in with her relatives – including the masturbation-obsessed, eighteen-year-old Jiro – and begins attending Tonbori Private Elementary School. Between meeting new friends such as Miki and Kenji, Fuuka finds herself learning about lingerie clubs, the best way to put on a swimsuit, and when it’s not a good idea to walk around the house naked. For a typical elementary school student, Fuuka’s not-so-typical body helps keep every day a new adventure!
Both shows are about elementary school kids who just happen to be in adult sized bodies. Yoiko has a girl main character and is way more pervy where Recorder to Randoseru has a male main character and is more lighthearted comedic fun. Check either out if you like young minds trapped in mature bodies getting into all sorts of trouble.
