A young scientist opened a portal…
But not into a parallel world—into the blackness: the space between worlds, inhabited by creatures and fragments of destroyed worlds.
The creatures’ blood instantly reacts with the body, granting superpowers.
Let the hunt begin!… But only until it becomes time to pay.
Very soon, guests from the underside of the blackness will come for the main hero. Otherworldly creatures will take revenge for their dead brethren, and doomed worlds will demand justice.
One person probably won’t manage, so you’ll need partners—your copies from parallel worlds.
Plus, there’s one more thing: the cat is thrilled. He’s gotten into otherworldly creatures, mutated, gained superpowers, and it seems he’s preparing to take over the apartment… No, there’s a mistake—apparently he’s decided to subjugate all the humans here.
