There is something very, very, wrong with those hands.

Yui from ToLOVEru has a similar position like this.
This girl is trying to hide something...but what? She's wearing shorts underneath her skirt. I don't get it.

She still doesn't want you to see the shorts, I expect. Or maybe the artist just wants to have fun with it given that normally a girl would be trying to block your view.

Regardless, she's got to be one of the smartest girls in anime when it comes to stopping fellows from seeing her underwear.
