The year is 50XX. A world where science has reached its absolute peak. People call this massive metropolis "Neo Arcadia."

・In this neon city under the influence of the mega-corporation "Chronos Industries," people live their daily lives alongside cyborg bodies and the latest technology. ・Drones monitor the city 24 hours a day, a sky dome stretches overhead, and the weather and day-night cycles are managed by a central AI.

──However, a top-secret experiment conducted by the corporation eventually shattered the world's balance.

・Grotesque lifeforms unleashed from the experimental facility came to be known as "monsters" and began attacking people throughout the city. ・Goblins, giant plants, and twisted beasts—these are now a reality, threatening the daily lives of the citizens.

・The ATD (commonly known as Agents), specialists in monster extermination, head to danger zones today upon receiving a request.
