Yami-ma no Mamiya

Yami-ma no Mamiya (闇麻のマミヤ; "Mamiya: Dark Mahjong") is a Japanese manga series written and illustrated by Nobuyuki Fukumoto. It is a sequel to Fukumoto's manga Ten, set 20 years later. It has been serialized in Takeshobo's Kindai Mahjong since July 2019. Yami-ma no Mamiya features a unique variant of mahjong, called "Yami Mahjong," or "Darkness Mahjong," in which point sticks are spent into a bank, called "dark deposits," in order to hide one's tile discards, as well as reveal these hidden discards at a higher price.
