Audiences will begin to grasp what they are in for early on, as loser Nishi, too wimpy to try to save his childhood sweetheart from gangsters, is shot in the butt by a soccer-playing psychopath, projecting Nishi into the afterlife. In this limbo, God - shown as a series of rapidly changing characters - tells him to walk toward the light. But Nishi runs like hell in the other direction and returns to Earth a changed man, driven to live each moment to the fullest.
