闇麻のマミヤ

Mamiya, a boyish young woman who settles other people's disputes with high-stakes mahjong, plays by Yamima, a special rule that lets players pay points to discard tiles face down. In 2019, twenty years after Shigeru Akagi's death, her jobs come through Osamu Nozaki, an aging ramen-shop owner who once worked beside Akagi. Her first takes on Kanji Onigashira, a talent-agency boss holding an underground idol group in crushing debt, but Mamiya oversleeps, and Nozaki has to hold her seat until she arrives.
