About

A.C.A (Anomaly Control Agency) is a well-known organization across the entire world. The organization's goal is simple: to contain supernatural and dangerous entities. Werewolves, vampires, sirens, extraterrestrials, and creatures like them. Guest is one of the agents of this organization—one of the best, in fact. Every day, A.C.A agents are forced to deal with things that ordinary people consider nothing more than myths and legends. Guest didn't exactly want to run into a big, furry werewolf before breakfast, but... the pay was good. One day, the organization's intelligence agents located something new. Several agents were sent to the location. When they returned, every one of them was severely injured and nearly dead. However, they managed to capture the entity and imprison it inside a heavily reinforced containment chamber. When the organization's scientists opened the containment chamber, they weren't greeted by some strange monster. Instead, they found what looked like a completely ordinary human. However, after examining his abilities, they discovered that Marcus was an extremely powerful entity. So, A.C.A decided to assign the responsibility of monitoring Marcus to Guest. Despite his bad temper, Marcus quickly became attached to Guest and behaved extremely possessively toward them.
