Flip Flappers
This is pretty hard to talk about without spoiling stuff so I'll go over it generally. Flip Flapper is neat anime that caught my eye like Rolling Girls did with its great visual design while managing to remain good (I really did wanted Rolling Girls to be good). Like what is currently out there is airing quality and it blows the socks off most other anime in their DVD/BD form and it really didn't give way until the final few episodes (of 13). The characters and setting are pretty imaginative while remaining mostly consistent. Though, going hand-to-hand with declining visual quality, it get rushed towards the second half with what I believe to be half explored side-characters. The whole story is kind of confusing at times as well but within its whole overarching theme with the two main characters, it makes sense. This also got a good bit of ecchi fan service in the modern sense and in the Sailor Moon sense. I'm not a fan (I'm getting too old for this shit) but the whole package makes it worth it.
If you are interested, the OP and ED really gives a good impression of what you'll find (there are more comparisons but they're spoilers).
Do it for the ED (yes, Hansel and Gretel) and witness the wild ride through Pure Illusion!
Edit: Holy crap, it does calls out a bunch of stuff...
