MTL - Be a Leader In a Primitive Tribe - Chapter 99

Cross is a laborer and helper working in multiple construction sites and stores to pay his bills and food. The pay isn’t much, but he is content with his life. He has a job, a crappy rented apartment, and a girlfriend.

But it all shatters when the world changes one day. A strange phenomenon teleports everyone into a world of fantasy, magic, dangerous beasts, and mystifying creatures.

Everyone is given abilities, skills, and spells and can level up like in a game.

And that’s not all. They are transported in a medieval timeline where technology is nonexistent, and living is harsher than one might expect!

When Cross swipes his hand, a screen appears, and the first thing he read.

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.
