Liora was a pampered royal princess, with loving parents at the forefront and eleven royal brothers at her back. Always adorned with the finest silk and served with exquisite dishes while lounging in her palace.Her biggest concerns? Which dress to wear for a banquet and how many more hours she could nap before her royal duties caught up to her.But fate (or some seriously bad karma) had other plans. One moment, she was sipping fine wine and but the next moment-boom!—she wakes up in a world where people are eating each other, the sky is covered with ominous veils that look like it wants to swallow the world, and worse, her royal status means absolutely nothing.What she can tell more about her poor condition is that she has no servants, no food, and no idea how to fight off the disgusting zombies, who are trying to take a bite out of her.Just when she’s ready to scream at the heavens for an explanation, a cold mechanical voice rings in her head:[Welcome, Host. You have activated the Overlord System.]Overlord? That sounds powerful, right? Wrong. Turns out, she starts at the bottom of the food chain with no powers, no weapons, and zombies that see her as their next snack.While others awaken abilities like fire manipulation or super strength, she gets... a system that gives missions with questionable rewards and always tries to drown her in a huge debt.Fight a Level 2 Zombie with her bare hands? Sure, why not? Survive hordes of zombies while the system nags her? Classic. But as she battles to level up and gathers allies (some willing, some just too scared to say no). She realizes—maybe she isn’t as weak as she thought.Because when the world falls into chaos, only the strongest can rule. And if the system insists on calling her an Overlord, well… she might as well live up to the name.Power, danger, and a system that may or may not be trying to get her killed—welcome to the apocalypse.

The world was once at war with 10 alternate worlds. This was known as the Concept War and our world won 60 years ago. All of this was concealed so no normal people are aware of this fact in the current time.

After the death of his grandfather, the high-school student Sayama Mikoto is suddenly summoned by the giant corporation IAI. He learns this world is headed for destruction due to the acceleration of the Minus Concepts. To prevent this, negotiations must be undertaken with the survivors of the other parallel worlds so their 10 concepts can be released.

And so Sayama is caught up in the final battle to clean up after the Concept War which left behind so much enmity.
