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!
Hey Yamada, what does it taste 
like when you kiss Shiraishi-san?
Sag mal Yamada, wie schmeckt
ein Kuss von Shiraishi-san?
Oye Yamada, ¿a qué saben 
los besos de Shiraishi-san?
Oye, Yamada, ¿a qué saben 
los besos de Shiraishi-san?
Ehi, Yamada, che sapore ha
 baciare Shiraishi-san?
Ei, Yamada, como é quando
você beija a Shiraishi?
Эй, Ямада, какой на
вкус поцелуй с Сираиси?
