In another timeline, before there was the walls, there was a brutal and power-hungry king named Fritz who used the power of his slave Ymir to vanquish his enemies and expand his rule in an attempt to rule over the whole world. Amidst this turmoil, a hidden kingdom recognizes the danger that King Fritz is to them and sends one of their best soldiers, a young man named Flukey, to sneak onto King Fritz territory and kill him. And at his arsenal is his will and the hand of fate to help him see his mission through for the greater good his kingdom, Fritz's, and the world.
