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! (FUNimation)
