Yuta Hibiki wakes up in the home of his classmate, Rikka Takarada, with amnesia. A voice from an old computer, identifying himself as "Gridman," has a mission for him, but can he even survive the next day of school without his memories?
But never mind her!
I'd like to see this Gridman guy, too!
¡Pero olvídate de ella!
¡Yo también quiero ver a este tal Gridman!
Mas esquece isso!
Queria saber quem é esse Gridman aí!
