You watch these girls play mahjong and forget you're watching a sports anime about a tile game. The Nationals stripped away everything that didn't matter, the fanservice, the filler, and replaced it with pure character momentum. Every hand becomes a conversation between players, every tilt and read a small act of defiance against impossible odds. This is what happens when a show trusts its premise enough to let strategy breathe. By the end you're not rooting for Kiyosumi to win; you're rooting for them to understand each other one more round before it's over.

Having come through the regional tournament, the Kiyosumi High School mahjong team moves on to the national stage of the Interhigh Mahjong Championship in Tokyo. The rivals waiting there play at a far higher level, and some of them may be even stronger than Saki Miyanaga herself. Saki refuses to give up, though, because she is determined to reach her goal of meeting her sister face to face again. The competition is a sports story with slice of life elements, told over 13 episodes.
