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!
I went outta my way to go to a high 
school where no one knows me,
Da geht man extra an ’ne Schule,
wo keiner einen kennt …
Me tomé las molestias de venir a una preparatoria
 en la que nadie me conociera,
Me tomé las molestias de venir a un 
instituto donde nadie me conociera,
J’ai visé exprès un lycée
où personne me connaît…
Mi sono allontanato dalla mia zona per frequentare
 una scuola superiore in cui nessuno mi conoscesse,
Tive o trabalho de ir para o ensino médio
num lugar que ninguém me conhece,
Мне пришлось пойти в старшую
школу, где меня никто не знает,
