Park Jisoo, cousin of the former Weakest Hunter to the S-Ranked Hunter Sung Jin-Woo and also, one of the Shadow Monarch and successor of the King of Death, Ashborn.

After eliminating the all the Monarchs, Jin-Woo used the Cup of the Reincarnation to restart a new world and bringing back her maternal family and the others.

But after Jin-Woo did it and went back to his new world, Jisoo was somehow left behind with Ashborn along with the Shadows due of her ability unable to leave behind Shadows whom she cared. Ashborn explained to Jisoo since Shadow Monarch wasn't longer enemies to the Rulers, they should start their own world.

Jisoo along with her Shadows end up being teleported into a strange world of Heroes and Villains who were fighting in a deadly battle.

"Well, looks like I have to save the day again"

"Who are you?!"

"Me? Well, I'm just the Shadow Monarch from Another World"
