What is Keijo!!!!!!!!? Essentially, it's what you get when you weaponize T&A (boobs and butts), essentially making asses out to be extremely lethal weapons. Throw in the universal shounen, "rise to the top" plot, and there you have it—And yes, Keijo!!!!!!!! does take the plot, the asses, and the sport itself, very seriously, and with a straight face, characters will absolutely comment on how overpowered ones' particular ass may be. Naturally, expect tons of incidental "fanservice" as a result of weapon choice. If what you really want to see is mad gymastics do T&A, and T&A doing mad gymastics, martial arts, and more, this isprobably the show for you.
