Amidst the nocturnal decay of Rua Augusta, a clandestine tattoo studio called "Dirty Soul" acts as a drain for souls for a timeless entity known only as Tattoom. The studio doesn't use conventional pigments; it extracts traumatic memories, regrets, and grief from its victims, transforming them into a "living ink" that permanently alters the anatomy and psyche of whoever enters. The story follows Lucas, an insomniac searching for meaning, who ends up being the blank canvas for the entity's morbid preservation project. After undergoing the "session," the victim is transformed into an extension of the studio itself, a new guardian forced to wait for the next tormented soul seeking refuge in the basement. The tale is a spiral of bodily and existential horror, where the body becomes an inescapable catalog of traumas, condemned to eternal repetition under the watchful eye that cries ink.
