Series Synopsis
Yuta Hibiki (voiced by Yuya Hirose) wakes up with no memory of who he is. Lost in an unfamiliar city, a recollection or two might help him out immensely because:
1. Everywhere he looks, Yuta sees kaiju (giant monsters) standing dormant around the town, and no one seems to notice them.
2. A voice in Yuta’s head is telling him to remember his mission.
Suddenly, a new kaiju appears and starts attacking the city. Unsure of what to do, Yuta comes across an old computer, where someone is beckoning him to fight. The image on the screen calls itself Gridman (voiced by Hikaru Midorikawa), and following his instincts, Yuta decides to join the unknown warrior in battle.
Yuta and Gridman form into a massive robotic hero and face off with the kaiju; defending the city. However, none of this explains what is going on or who is behind the attacks.
