- Description from novelbuddy

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.

Jobs, hobbies, lifestyles—the world has advanced to a point where nothing can be separated from VR anymore. And now, a VR game was released using the most cutting-edge technologies; its name was “Boot Hour, Shoot Curse.” Our protagonist had no choice but to play solo during the closed beta test, but once the game officially launched, she made lots of friends (but not necessarily with the players), formed a huge clan (but not a clan of players), and matured as an individual.

Though he received the skills necessary to teleport across worlds, the king who performed the summoning ritual attempted to trick him into wearing a slavery collar, this annoyed him so he kidnapped the princess and returned to Earth.
