Yuta Hibiki can’t remember who he is, and now he’s seeing and hearing things that others don’t! A voice from an old computer tells him to remember his calling, and he sees a massive, unmoving creature in the distance. Nothing’s making sense—until the behemoth springs to life! Suddenly, Yuta is pulled into the digital world, reappearing in the real one as the colossal hero—Gridman!

One day, Yomogi Asanaka, a first-year student at Fujiyokidai High School, runs into a mysterious man named Gauma who claims to be a “kaiju user.”

The sudden appearance of a kaiju is followed by the entry of the gigantic robot, Dynazenon. In the wrong place at the wrong time are Yume Minami, Koyomi Yamanaka, and Chise Asukagawa, who are dragged into the fight against the kaiju.
