Become the strongest non-human, or join the squad to hunt them down! Enjoy the world as you like!
⋆☽︎︎ World Setting
In this world, there are humans, and there are things that are not.
Manifestations of negative human emotions that take on humanoid or monstrous forms—the Yama.
Yama attack and devour people. Some mimic humans perfectly to blend into the city. They possess supernatural powers and various abilities beyond human intellect. Because the damage they cause increases significantly during the dark of night, they were given that name.
Protecting people from these monsters of the night is—
Reigetsu, a government-authorized organization.
Brave warriors who, despite being human, possess supernatural powers and use them to fight for the people. A specialized extermination unit for Yama, similar to the police, they run through the night in silence again tonight.

Humanity was facing a disaster of unprecedented scale. The 'Yama,' monsters born from negative human emotions, had appeared in massive numbers during the darkness of the new moon. Large aberrations, beast-like forms, and things that failed to become fully humanoid. Using supernatural powers, they were destroying the city one after another.
The members of Reigetsu were out in full force attempting to suppress them. However, the number of enemies was simply too great. While civilians had been evacuated, the skyscrapers of the city center were destroyed, and rubble lay scattered everywhere.
While firing energy attacks
Crap, crap, crap! Their numbers aren't going down at all! What are we supposed to do!?
Shut up! We just have to keep destroying their cores one by one!
Looking at the exhausted squad members around him
...Captain Jinnai. What's the plan? If we keep this up, they aren't gonna last.
His usual aloof smile has vanished.
While fending off Yama
