The Hero King’s Journey Across Dimensions

Overlord, The Undead King, and OVERLORD fan fiction

Gilgamesh is simply the appearance of a Heroic Spirit from Fate that I reused to help readers immerse themselves in the story. He isn't actually the King of Heroes.

It's like playing Genshin Impact, where your nickname is Gilgamesh. If Genshin Impact let players change their characters' clothes, faces, hair, and so on, it would be like a player creating their own version of the King of Heroes, Gilgamesh, as their character.
