A young scientist opened a portal… but not into a parallel world—into darkness: the space between worlds, teeming with creatures and fragments of destroyed worlds. The creatures’ blood reacts instantly with the body, granting superpowers. Let the hunt begin!… But until it’s time to pay. Very soon, guests from the underside of the blackness will come for the main hero. Otherworldly creatures will avenge the dead of their kind, and doomed worlds will demand justice. One person here can hardly cope—so you’ll need partners: your copies from parallel worlds. Plus, there’s also a cat in heaven’s bliss: it’s stuffed itself with otherworldly creatures, mutated, gained superpowers, and it seems ready to take over the apartment… No, there’s a mistake—apparently it decided to subjugate all humans.
