Purgatory Comics focuses on a young woman named Cola who runs from her adult responsibilities and hides in a failing comic book store.

After years of obsessive research, a brilliant but isolated physicist succeeds in creating the world's first artificial black hole inside a secret laboratory. Instead of unlocking the secrets of gravity, the experiment tears open reality itself, revealing an impossible truth: the world is not a globe, but one of countless vast, layered planes stacked beyond human perception. The artificial singularity acts as a doorway between them—endless, silent worlds where familiar cities stand abandoned, horizons stretch forever, and something ancient waits just out of sight. For generations, humanity dreamed that first contact with extraterrestrial intelligence would bring enlightenment, peace, and answers to the universe's greatest mysteries. Instead, the physicist discovers the horrifying truth: the "alien civilizations" hidden beyond the planes have always known about humanity—and have deliberately remained silent. Their first consultation with mankind is not a celebration, but a warning. The planes were never meant to be crossed. Every civilization that pierced the veil awakened something older than the universe itself... and every one of them vanished. Ignoring the warning, the physicist ventures deeper into the liminal worlds. Each crossing fractures reality, causing people to disappear, time to distort, and impossible places to bleed into our own. Soon, unseen entities begin following him back through the black hole, feeding on the cracks between dimensions. As the boundaries separating the planes collapse, Earth becomes the next world on the brink of extinction. The greatest scientific breakthrough in human history becomes the catalyst for an ancient catastrophe—proving that some doors remain closed not because they cannot be opened, but because something on the other side has been waiting for someone to do it.
