MOUSE is everything an ecchi manga should be. Trying to pull off the heist of the century? Hold on, look at some boobs first. Life in danger? Hold on, we need to check out some boobs. Holy shit, is that a Dragon?! Sorry, too busy looking at boobs.
Yuushibu is in my opinion the most under-rated ecchi anime of 2013. It had a novel concept, good production values, a solid soundtrack, likable characters, and a fun vibe. And when it came time to deliver fanservice, Yuushibu didn’t hold back, either.
