Mushoku Tensei: A Hero's Legend Beginning with the Great Displacement

No one is born a hero. At the very end, the girl returned to the place where the story began, and there she met the hero who had once made a promise, then left without permission. This time, the hero did not break his word. He made one final vow to the girl: "From now on, until the end of the world, we will never part."

And so the hero's legend came to a close.
