Yuta Hibiki awakens with amnesia and the ability see things that others cannot. He first encounters a Gridman in the reflection of his friend Rikka Takarada�s computer and it tells him to �Remember his calling,� but Yuta doesn�t understand what this means. Later, in the distance, he sees an extremely large monster but it doesn�t move. It�s only when Yuta gets to school that the two sightings make sense: a monster attacks and the hero Yuta saw in the computer screen pulls him within the computer and transforms Yuta into a giant hero named Gridman.
