Horizon of War Series - Chapter 15

First-Generation God King Tang San, with a trace of divine consciousness, roamed the universe, searching for the world where his wife had reincarnated. Guided by that divine consciousness, he arrived at a place called Demon Monster Land, only to find that it was a world where humans were as lowly as livestock…

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.

I'm not.”He studies her—this heiress in designer armor, hiding rage beneath polish. “So your grand plan is a wedding band as revenge?”“No,” she says, stepping closer, close enough for him to smell the jasmine and gunpowder. “It's the only weapon they won't see coming.”Their fathers built empires by manipulation and control.

A world where the [Demon King] was defeated by a [Hero] that came from another world. People carelessly forgot about their fear of the [Demon King] and of monsters, living in peace.

In a forgotten and run-down cave in the mountains, a new monster that should not have been born was given birth.

The monster’s name was the [Black Ooze]. It was nothing exceptional other than its black color, an ordinary slime.

However, this slime had the special characteristic of being able to take the abilities of the living things it swallowed. It preyed on an insect that had paralytic poison, as well as other animals. Following that, it attacked a human, obtaining his knowledge and [Desire].

Before long, the monster established its target as the female mage that came to explore the cave.

This world still wasn’t aware.
