Flashy Adventurer System : Show Off to Get Stronger! - Chapter 800: Alpha Three

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.

He was about to join the beta test on the newest VR games, Second World.

Jun Ye travels through worlds for unexplained reasons and is always cast in subservient roles. Unfortunately, that wasn’t his style. Let the counterattack commence!
