Even then it's only a few shots in the first couple of volumes. After that it becomes 'clean', and now they tend to shy away from fanservice.
The anime is a good watch, perfect for when you've got half an hour to kill. Fire up whichever ep you've got and there you go. Not an anime you 'follow' or anything, just stock up and watch a couple of eps when you're in the mood for something simple and fun.
Season 2 finale kicked ass though. Fuck yeah Garuru platoon.
