SSSS.Gridman DVD 1-12 (English Ver) Anime
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.
