Short answers, pulled from the story.
The 2004 film Mind Game by Masaaki Yuasa follows a 20-year-old NEET from Osaka named Nishi who dies on a subway and is sent to a limbo by a shape-shifting deity called Kami-sama. Nishi pleads for a second chance to live and embarks on a surreal journey through the afterlife and back to life again while the laws of physics and narrative logic bend to the whims of the story.
Masaaki Yuasa directed the 2004 film Mind Game and chose to tell the story with a patchwork of disparate visual styles that mirror the protagonist's fractured psyche. The film features a visual style that shifts dramatically from the gritty realism of the subway to the abstract, dreamlike landscapes of the afterlife and the vibrant, chaotic streets of Osaka.
Inside the belly of an enormous whale, Nishi, Myon, and Yan find themselves in a suspended house constructed by a former yakuza who has lived there for more than 30 years. The trio builds a motor boat using spare parts and fuel from the car they arrived in while the whale itself begins to die and the water level inside rises.
The whale returns to Osaka on the day before the final match of the World Cup in the 2004 film Mind Game. The four characters manage to escape by flying through the air in a motor boat they built from the wreckage of their previous life.
The film Mind Game ends with the narrative structure looping back to its very first scene but with a subtle change where Myon's leg does not get caught in the door of the train and the yakuza is left behind on the platform. This change suggests that the characters have the power to alter their fate and rewrite the story of their lives.
