In MIND GAME, Nishi is an aspiring comic book artist who feels like his life is passing him by. One night, on the street, he runs into his childhood crush, Nyon, who tells Nishi that she's engaged to be married. They go to Nyon's father's restaurant to get caught up, see Nyon's sister, Yan, who also works in the restaurant, and meet Ryo, Nyon's fiance. Two yakuza -- one older, one younger -- enter the restaurant, the younger one looking for Nyon's father, who seduced the yakuza's girlfriend. During the altercation, Ryo is killed, and the yakuza attempt to rape Nyon while Nishi curls into a ball, crying and afraid. The yakuza presses a gun to his rear end, and when Nishi finally gets the courage to fight back, he's shot and killed, while the older yakuza kills the younger yakuza. Nishi finds himself in a bizarre afterlife where the image of God changes every second. God beckons Nishi to a red portal where he will disappear, but instead, Nishi, determined to live life to the fullest, runs in the opposite direction, escapes the afterlife, and returns to the restaurant with the gun pressed into his rear end. This time, Nishi fights back, kills the yakuza, and escapes with Nyon and Yan in one of the yakuza's cars. Nishi escapes the yakuza who pursue them in their own vehicles by driving off a bridge. They are then swallowed by a whale and end up in the hideout of an old man. They keep trying to escape, but are unable to do so, but as the whale is slowly dying, Nishi, Nyon, Yan, and the old man make a final attempt to escape the whale and return to their home town.
