This may not have been a great anime, but the animation is better than static screenshots made it out to be and the service level was quite high for a fantasy-action anime.
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.
