Fighting monsters from another world, in general, is not an easy and dangerous task, especially since these monsters are not visible to the average person. But there are those who see them. These are the only ones who serve in a secret organization that has subjugated the passages between worlds. Different people. Different cities. Various weapons. Different worlds. Even eras happen to be different. The only thing that remains constant is their work. Cleaning. Because they are Cleaners... Like a fire brigade, they arrive to calls, always ready to fight the evil spirits. And the place where they met was and remains a bar. Cover approved by the author
