A book filled with nothing but isekai, reverse isekai and monster girls!
A succubus looking for prey in the human world, an elf princess looking for someone to impregnate her, a princess knight looking to fulfill her orc fantasies and a parasite looking for a host are just some of the characters that get transported into our world in this book!

But some get transported the other way too: a pair of slutty gyarus who end up in a den of goblins and a salaryman who gets a hero cheat power to level up his companions through sex, for example. You'll find all of this, and much more (a succubus oyakodon, perhaps) in this amazing book!
