Very little :/
In fact, there is more stuff girls find interesting... :P
Like that guy who suddenly goes topless sometimes, or the fact that two guys almost seem to be in love with the main character (also a guy), even tho it's never proven, and they probably just respect him alot.
But don't let it scare you xD
it's still a good anime. And I bet you can find a girl you like there without her having huge chest and ecchi scenes :P
It's not as good as FMA:B in my opinion, but damn close. It's really funny, and you get attached to it way more emotionally than FMA:B.
Without giving out too many spoilers: It's about people who lived horrible lives who want revenge for God making their lives unfair. They're in some kind of afterlife, where everyone's immortal, and they fight a girl they call Angel, as they believe her to be God's guardian of the place. Her job would be to make them disappear and be reincarnated as something else, something they refuse to, as they aren't satisfied with their lives a all. One disappears when they accept the situation.
