Hana Iro fanservice to me was pretty much the opposite of sexy. The only chance they had was with Yuina and sometimes Nako, and it's not like Minko has anything that isn't a washboard. Plus it had other opposition like Guilty Crown (almost...) and Ben-to so it wasn't easy for 2011.
Now True Tears-- Hiromi has an awesome figure and can still play sports. And has the best looking ass PA has drawn to date. That is much sexier. The fanservice was more subdued save for random Noe panty shots, but it was still there.
Now I'll stop before I get stabbed by the other fans.
