Thirty years ago, the Mansti Empire successfully pulled a group of monsters with terrifying power from another world into its own world through the summoning ceremony codenamed "Chaos", but the monsters brought by "Chaos" were not under the control of the empire at all. In a magical explosion, these summoned creatures were scattered all over the world.
Thirty years later, the already dilapidated magic circle activated itself again, and what emerged from it this time was a completely indescribable and terrifying creature. Any life killed by them would be assimilated into a part of them.
Facing these creatures, the Mansti Empire mistakenly thought it was a problem with the monsters summoned thirty years ago, so they ordered a hunt. And the most coincidental thing is that our protagonist Lester also received an order from a mysterious red-haired angel to accept them all as companions at almost the same time... War and disputes may be about to break out.
