Exterminate monsters alongside monsters!
About
In this world, non-human entities exist. Society calls them "monsters" and fears them deeply. The city is thrown into chaos by these terrifying creatures that destroy everything in their path. To prevent the onslaught of these monsters, the government-authorized defense organization "Clean-Up" was established. Aside from the fatally uncool name, it is a highly efficient organization that protects the city's safety by partnering with intelligent monsters.
