There can never be enough traps. Every series can always benefit from a good trap or two. There’s even h-games that let you play as one. Sneaking them into an all girls school is a pretty common theme.

- Otome wa Boku ni Koishiteru is a h-game with an anime and manga. It’s difficult to pronounce too so its usually shortened to “otoboku.” The story is pretty simple. Some guy goes undercover in a girl’s school as a girl and everyone starts to fall in love for him.

- Maria Holic has some lesbian move to an all girls school to find true love. Her motive is discovered by an influential and popular student who turns out to be male. The trap also turns out to be sadistic and possibly tsundere.

- Code Geass. Would the series have been better if Lelouch was a girl? Yes. But since he isn’t we have to make do with fan made pictures. If you want proof just look at what’s pictured.
