Synopsis
In a world where Earth's resources are completely depleted and progress has come to a standstill, the planet is split into sections called "Units." In Unit 74, a boy named Hajiki Sanada lives with his family in Night Town, a place where electricity goes out at midnight every night. Central to the story is an object known as a GAD, which can transform materials based on the user's emotions. The size and shape of this transformation depend on how the user feels. When Hajiki accidentally touches a GAD, it turns into a huge robot called a Tekkoudo, or "Iron Giant," which he names Lightning. As he discovers that others also possess Tekkoudos, Hajiki must figure out how to understand and connect with these beings that he views as similar to himself.
