After his death, Bern awakens 10 years into the past as the third prince of Kailis, the enemy country.

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.

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