Ao no Kanata no Four Rhythm - (Four Rhythm Across the Blue)

Gravity is solved, they found a new element which is anti gravitational. They started using them in shoes to enable people to fly. In Japan, this however works only in the four southern islands of the Japanese archipelago for some reason.

Through this advancement, a sport is developed around it called Flying Circus. Rules are simple: fly and reach 4 flying buoys like in baseball, reach a buoy to earn a point. Tapping on the opponent’s back can also earn a point.

Meet Kurashina Asuka: a pink haired airhead who moves to one of the four islands.  

She starts learning how to fly and incidentally she is pulled into the world of flying circus. 

The trainers realize that she is a natural and she revives interest in the sport in her school again.

The new amateur team along with Kurashina starts participating in tournaments and from that point on, its what you expect from any sports movie or anime. Talented but Tainted coach tries to help a rookie team and leads them to victory. And they do win.

Overall the anime is fun to watch and is paced well, so you hardly notice that you're binging it.
