Yeah, a manga with some person (girl) getting memory loss (possibly in a school setting)

And a manga with a perverted girl, cause you don't see them too often

Lalala~

Memory Loss: (neither is school setting though)
Blood+ (shounen) - main character, Sayo
Ayashi no Ceres (shoujo) - male lead, Toya

Here's a thread for perverted females:

If you've ever thought or said "Nice Guys finish last" and really meant it, then you should probably read this LJ post by DivaLion. It's incredibly insightful whether you're male or female.

From a bumper sticker I like:
"If you're gonna ride my ass, at least pull my hair."

I'm already reading Blood+, and Ayashi no Ceres looks interesting.
Also, thanks for the link (I now have like 10 more pervy girl mangas) 😀
