Shitsurakuen (InstanceTopic, 7)
From Compile Worlds
Shitsurakuen is a manga about a mysogynistic academy. Except not, if you read far enough into it. In any case, they set up a virtual battle system, kind of like BakaTest, where the male students battle using the female students as weapons, by pulling the weapons out of their chests (however that works).
It's got its fair share of cute girls in any case...
