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!
What the heck! You're way 
too good at guessing things!
Was geht mit dir?!
¿Qué demonios? ¿Cómo

¡¿Qué?! ¡¿Cómo eres 
tan bueno adivinando?!

 Sei fin troppo bravo a dedurre cose!
O quê? Você é muito bom
 em adivinhar as coisas!
Да что ж такое?!
Ты слишком умный какой-то!
