Frozen Mahjong Tiles: Underground Mahjong Battle Record - S01

Ever since he moved into his own apartment, quiet high school student Kei has been chasing a new thrill. He soon gets into mahjong, but his life takes a dramatic turn when he is forced to play against a criminal group. Even with the odds against him, Kei manages to outmatch them. Instead of taking a cash reward, though, he decides to take an abducted girl named Amina under his wing. Because of Kei's skills and cold playstyle, the mysterious Hideharu Seki takes an interest in him, introducing him to mahjong parlors and new potential opponents. But when he faces an experienced player named Doujima, Kei is badly outmatched and only narrowly avoids falling into serious debt. If he wants to protect his new life with Amina, Kei has to find a way to outwit these shady characters and come out on top in every game he plays.
