Girls train to be Keijo (a weird sport) players.
Length: 12 episodes
The sport of Keijo involves knocking the other players off a floating platform using only your boobs and your butt.
I watched this anime over the course of two days. It was a strangely addictive and slightly perverted sports anime. (Though everyone is over 18 so it’s all okay.)
There were many close-ups of boobs and butts.
Anyway, the anime is about girls who have joined a Keijo training school. They get to know each other, have a training camp in Kyoto, and compete against their rival school.
