The game of Igura, played in the ruined city of Toshima where disaster has struck, demands players to put their lives on the line. Akira finds himself imprisoned for murder in a society run by the underworld, and his only chance at freedom lies in winning the game. However, whether he emerges victorious or experiences heartbreak, he must brace himself for the final battle. The legendary bishonen game serves as a source of inspiration for this competition.
