It's as easily overlooked as anything a regular anime would do though. The gameplay is so much fun its worth looking past the mild fanservice. 5 was a weird departure for me, I rented it and had trouble getting into it since they made me keep switching characters in the "story" mode. I'm used to choosing my character and just going through some weird little short thing. Or just going into survival or tag mode and raining hell down upon the computer. But the stories were so bizarre and weird, they amused me
