As their souls linger on the edge of the afterlife, a mysterious force intervenes, merging their fragmented souls together with a new being.

The head of the London Association of Mages, the most powerful Saint Archmage in the world, Audrey Davis, accidentally transmigrated to another world due to a magic accident. She was an 18-year-old human girl.

I thought the world was vast, for me to wander, but now, it has only become a cage. For a life unhindered, I wield a single sword to pierce the ninth heavens. People find me displeasing, but there’s nothing they can do. That’s the kind of life I love!“Stop! I paved this path and I planted these trees. If you want to pass through…”“Brother, I come from the Dustfallen sect.”“What? The Dustfallen sect! Piss off!”This pitiful sect was so poor to the point where even bandits did not want to waste time on it. However, how could this sect, these nine measly people, be ordinary? What you see is only what they wish for you to see. What you can’t see is the truth!Mu Yu—a young human boy with the powers of elemental demons—accidentally joins the impoverished Dustfallen sect. The sect that even bandits did not want to waste time on was actually hid great talents, concealing a huge secret! You look down on my sect? Then that’s your ignorance!

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.
