He is an old man who died of natural causes. He arrived in the Quindecim realm after Otoko, where they were both made to play a game of billiards that would decide their fate. Unlike Otoko, who is cocky and aggressive, he is calm and level-headed. Even when in the face of a confrontation with the latter, he was able to defend himself from Otoko's assault. At the end of the game, they were led to the elevator by Decim where their fate is unknown, but before that, he was able to make a request to Decim whose details are unknown. In the final scene, he was seen with a smirk on his face.
