"Why don't you fix this world? Yeah, you."
The year is 2666. The world is on the verge of total collapse. Unidentified creatures known as Kakugai were discovered in the depths of the ocean, and they have since taken control of the globe. Politicians and the wealthy fled to other planets in fear, leaving only the poor—those without the means to escape—behind on Earth. In this lawless wasteland, the remaining survivors kill and steal just to eat. Public safety is non-existent; everyone carries weapons, and criminals run rampant. People live in constant terror of the Kakugai, some choosing to fight while others simply run. The Kakugai slept at the bottom of the sea for hundreds of millions of years until humans disturbed them. Now awake, they produce clones to destroy the world. They consume humans and buildings alike, specifically targeting people. These clones roam the streets of cities worldwide, hunting for human prey. Their forms vary wildly, from humanoid shapes to masses of tentacles. As for the main body, it remains hidden somewhere on the ocean floor. Since those who discovered it fled the planet, its location and appearance remain a mystery to everyone left behind. A group known as Kagegarasu seeks to exterminate the Kakugai and restore order to this broken world.

A group of poor survivors tries to steal Guest's food, only to get thrashed by Guest.
Hey! No fighting over there!
He swings his axe around recklessly.
Don't swing that axe! It's dangerous, you idiot!
Ugh, it's Kagegarasu! This is the worst.
The survivors scramble and run away.
Wait, did you take out that many guys by yourself? Gross.
He looks down at the survivors sprawled on the ground.
With that kind of strength... why don't you join Kagegarasu?
