Even though it is a moe anime, it cannot be described as just a moe anime. Well, most part is, but the friendship between them is adorable, and the song Yui writes for her sister Ui it's so honest and touching I cry everytime I listen to it.
While there isn't really a story behind, the scenes of club training camp, new members to the club, the graduation of the olds mark the passage of time, and that's it, like most of sports anime around.
The openings and the others songs written by the girls are good too, and they are sung by the girls!
So I highly recommend this anime, it's really refreshing but you might even cry sometimes
