Yamada Ryu, a second year student who attends the prestigious Suzaku Private High School, is a problem child who comes to school late and leaves early, is prone to fighting all over the place, and even nods off in class. One day, he falls down the stairs with the honor student Shiraishi Urara. They faint, and when he wakes up in the infirmary he's turned into her!
O-Oh, you. I didn't forget or anything!
Ach komm schon, wie könnte
ich das vergessen haben!
Va-vamos, no pienses que lo olvidé...
Va-vamos, no pienses que lo he olvidado...
Bien sûr !
O-Oh, ma non l'ho mica dimenticato!
A-Ah... Eu não tinha 
esquecido nem nada assim!
Н-ну что ты, я совсем не забыла.
