In a dystopian not-too-distant future in Japan, a boy takes on a robot army to regain his freedom—with the help of a few powerful friends.
Young Hiro has been hiding out for months with the mysterious robot who saved him and his yojimbot companions from the vicious onslaught by Topu’s drone army. But he can’t stay hunkered down forever. He and his friends have to find a way out before the island’s security forces close in, including a foe Hiro thought he’d seen the last of. The path ahead is full of danger, but freedom awaits Hiro at the end—as well as an earth-shattering revelation.
