Chapter 0: Prologue

A plain covered in the scars of battle.

The Gate had opened, and Monsters rained down.

It was a waterfall of grotesque creatures crafted by Demons.

Kuuuuung.

Even gigantic Monsters over 10 kilometers tall appeared.

The Fortress, which had remained unshaken through thousands of battles, now trembled.

Even Hunters who had survived countless brushes with death lost their courage.

“Fire!”

Magic poured down from the sky, and arrows and bullets rained from the high Tower.

The whole land flashed, sweeping away the Monsters.

But there were too many Monsters, and the giant ones weren’t even scratched.

The attacks of the High-Rank Hunters converged.

The S-Rank Flame Mage cast a spell that incinerated a thousand Monsters at once.

The Aura Blade of the swordsman who had slain the Demon Duke slashed through a Monster’s flank.

“It’s not stopping…….”

“If this goes on, the Fortress……..”

Even with the walls protected by the Shield of 128 Layers, such mass crashing into them would not hold.

There were too many other Monsters to handle.

When all the Hunters fell into despair, a Man Who Summoned the Legion soared into the middle of the Monster horde.

From the Gate he opened, more Monsters poured out.

Tens of thousands, hundreds of thousands, millions.

Shadows fell across the Fortress.

A Hunter looked up at the sky.

Something enormous was floating there.

It dwarfed even the giant Monsters.

Countless smaller things swarmed around it, blanketing the world.

The overwhelming forces summoned by the Man Who Summoned the Legion swept over the Monsters.

The seemingly endless Swarm of Monsters was crushed, and the unstoppable gigantic Monster was devoured—bones and all.

Having consumed everything, the Legion vanished beyond the Gate.

“What just happened?”

The plain returned to the state before the Gate had opened.

It was as if time had turned back.

A Hunter, wondering if it was all a dream, pinched his thigh.

It hurt terribly.

All the while, the Man Who Summoned the Legion, having summoned the Legion of Lifeforms, faded serenely into the Sea of Dimensions.
