Fairy Tail: The Godslayer's Infinite Journey

In a world where gods walked the earth, Lin Yuan once slew a god and became a Demon King who stood above the laws of reason.

But in that final battle, unknown to anyone, he died.

When he opened his eyes again, he was a boy taken in by Fairy Tail. The authorities he had once usurped from the gods had all fallen dormant, leaving him with only a monstrous physique, unfathomable magical power, and an innate awakening to God Slayer Magic.

He had thought that all he needed to do in this life was protect his noisy Guild and help that white-haired girl overcome her pain. Until the shattered gate between worlds opened once more-floating cities, underground labyrinths, demon territories, the city of Little Garden, Itogami Island, Heroic Spirit wars... World after world converged before his eyes.

And when time stood still on Tenrou Island for seven years, Lin Yuan finally set foot once more on the land where he had first slain a god.

This time, awaiting him were not only his lost authorities, but also a blonde knight who pointed her sword at him the very first time they met.

"If you claim to be the king of old, first prove to me that you are worthy of slaying a god."
