Now as two of my other reviewers pointed out there is no plot, other than the guessed after the first season daily life bs. It really is fan service that that is what escapes the other two reviewers. What did you expect from a show that had exposed breasts to being with.
Pros: Same characters and animation.
Cons: Super fan service, sometimes still frames for movement, Nova titties(Maybe that's a pro).
~SPOILERS~
I didn't think they were bad just not as interesting as the the show and yes the nudity is abound but what do you want from a 3 min special, plot and action. Grow up, you don't like nudity, then don't watch a show you know has nudity. If you watched the show or just like nudity, then watch the specials it's 18 mins nothing ventured nothing gained.
