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!
We're in this mess because you 
tripped and fell down the stairs,
Da wir nur in dieser Situation stecken,
weil du von der Treppe gestürzt bist,
Ya que nos metimos en este problema porque 
tropezaste y te caíste por las escaleras,
Ya que estamos en este lío porque te 
tropezaste y te caíste por las escaleras,
Après tout,
Siamo in questa situazione 
perché sei scivolato e caduto dalle scale,
Estamos nessa bagunça por sua
 culpa, você caiu da escada,
Мы сейчас в этой ситуации потому,
что ты поскользнулся и упал,
