Note: This review is mostly for the people (like myself) who are moving to the manga after starting with watching the anime airing this season. I haven't been too keen on super fanservicey anime as of late, but I had to check out Keijo this season because of the pure absurdity of the plot (and the "plot"). I actually ended up enjoying it a lot more than I imagined I would and had to check out the manga to see if it was the same kind of deal. I was not disappointed. I will say first off that the manga and anime open very differently. The anime picksup around the second arc of the story, whereas the manga starts off showing how she initially got started playing Keijo to begin with (not really a spoiler it's kind of the first noteworthy thing that happens in the manga). The characters in the manga are explored a lot more and, even though the events of the two productions line up pretty well, the manga goes into much more detail (as of right now 6 Keijo episodes are out, and the events of that are around the 50-60 chapter mark in the manga).

Now to the meat of it, the manga turns up the Keijo senseless absurdity tenfold, and I love every page of it. Most of the craziest stuff takes place past the point where the anime is now (though it seems it might get there by the end of the season), but the characters and techniques they use would be enough to give you an aneurysm if you were trying to actually take it seriously. It's essentially a test to see how many laws of physics they can break within the length of a chapter.

That being said, the characters, if a bit ridiculous, all have their charm, and their relationships (especially between the two main girls) are given a bit more attention than the anime. It focuses more on the action and less on the fanservice (though you get your fill of both and then some) than its animated counterpart, and is definitely one of those series I would recommend reading even if you're usually an anime-only kind of person.

tldr; It's insane, there's cute girls, and nothing makes sense. Don't take it too seriously, enjoy the ride, and enjoy nipples being used in ways that make you hurt just thinking about it.
