This universe's world is similar to ours, but monsters and monster hunters exist. The biggest monster hunter organization is the Hunter Society Alliance, also known as HSA. The HSA gave some of the monster hunters superpowers by augmenting them with body parts from monsters.
The story takes place in a world relatively similar to the real-life but with monsters. The main character is a monster hunter called Zara Cromwell. She and other monster hunters gain superpowers through experiments to be able to fight stronger monsters in the future. Warning: the series showcases various kinks and fetishes.
