Hikaru thinks he's finally rid of Sai for good, but the spirit has one last trick up his sleeve. When a mysterious card arrives inviting him to a special Go tournament, Hikaru discovers that Sai refuses to let their partnership end without one final, ridiculous showdown. What should be a serious competition becomes absolute chaos as Sai meddles with Hikaru's matches in increasingly absurd ways, forcing the reluctant pair into situations neither of them anticipated. The other players have no idea why Hikaru keeps muttering to himself and making bizarre moves, and the tension between Hikaru's desire to play seriously and Sai's determination to inject comedy into everything creates constant friction. This alternate take on a pivotal moment in their relationship strips away the drama and replaces it with pure comedic desperation. Hikaru must navigate the tournament while managing a spirit who's determined to make his final appearance as memorable and chaotic as possible. It's Go played by two people who absolutely should not be playing together, yet somehow still make it work.
