Ping Pong the Animation (2014)

11 episodes. Two childhood friends, the expressionless Smile and the cocky Peco, grow apart as high school table tennis turns from a game into a question of who they want to be. Masaaki Yuasa's scratchy, split-panel animation looks rough in screenshots and electric in motion, and the matches play like duels. What makes it a weekend essential is how every rival gets a full arc, so by the final tournament you are invested in almost everyone at the table. No sports knowledge needed, and the ending lands cleanly.
