A young scientist opened a portal...But not to a parallel world, but to blackness: the space between worlds, inhabited by creatures and fragments of destroyed worlds. The blood of creatures instantly reacts with the body, giving superpowers. Let the hunt begin!.. But until you have to pay. Very soon, guests from the underbelly of blackness will come to the soul of the protagonist. Otherworldly creatures will avenge their dead relatives, and doomed worlds will demand justice. You can hardly cope here alone, so you will need partners. Your copies from parallel worlds. Plus, the cat is also delighted: he got drunk on otherworldly creatures, mutated, acquired superpowers and seems to be preparing to take over the apartment... No, there is a mistake, he seems to have decided to enslave all people.
