Mizukiyo Minamikawa attends Joso Academy as Kanade Uryu's closest friend. This deep bond pulls Minamikawa into the celestial events surrounding the angels' search for a new God to replace the retiring deity. At school, Minamikawa confides in Kanade about his dreams and his quiet admiration for a fellow student, Sayuri, whom he often watches during her archery practice. His entire connection to the God selection process originates solely through Kanade, who participates directly as the God candidate operating under the alias Metropoliman.
