Hatakeyama

On the surface, Hatakeyama is just an ordinary university student, but behind the scenes he operates as a stand-in player in the shadowy world of underground mahjong. His easygoing demeanor and ever-present can of coffee mask a depth of skill that few can measure. In the story, he teams up with the protagonist Kei to take on a brutal high-stakes match where winners claim twenty million yen and losers forfeit their legs—facing the darkness of the gambling underworld with a calm, unhurried professionalism all his own.
