Thirty million years ago, Tiga sealed away the Eternal Core, and sealed himself away with it.
Thirty million years later, the Space-Time Tree teeters on the brink of collapse. Tartarus returns from a dead future and forms the Absolute Kingdom, intent on digging the Primordial Fragments out of Earth's core and resetting the entire universe. The only one who can stop him is Tiga, who is being corrupted by the fragments as well. But each time he uses the power of light, he loses another piece of his memory.
He forgets his son's face, the bonds he shared with his teammates, and even who he is. Daigo has forty-eight hours before he becomes a “gateway” completely.
Three hundred Warriors of Light gather across time and space. Saga awakens through Zero's faith, while Belial and Tregear fracture the Kingdom from within. But the true final battle is not between light and darkness. It is about what one person chooses to remember.
“Eternity isn't in the Core Fragments. It's in the person waiting for him to come home for dinner.”
