Before eradicating humankind from the world, the gods give them one last chance to prove themselves worthy of survival. Let the Ragnarok battles begin.

When evil forces threaten to resurrect Anthrasax, the God of Destruction, the Kingdom of Meta-llicana calls on a volatile dark wizard for help.

The people of the kingdom look down on the young Prince Bojji, who can neither hear nor speak. They call him "The Useless Prince" while jeering at his supposed foolishness.

The story follows Eren Yeager and Mikasa Ackerman entering Titan Jr. High, a school where humans and Titans study in the same area in coexistence. Because of a "traumatic" event, where the Colossal Titan ate his lunch back in middle school, Eren hates the Titans, and is constantly trying to find a way to rid the earth of their kind. Because of this, he has a hard time making friends, much to Mikasa's worry.
