Breeders of the Nephelym

Breeders of the Nephelym is an erotic action-adventure game that is centered around catching and breeding Nephelym, an enigmatic race of monster-human hybrids.

Nephelym are an immortal race of monster-human hybrids born from the Great Conception. Most of them are completely driven by lusr and it influences most of their actions. Blessed ones gain control over their desires to some degree.


Breeders of the Nephelym takes place in Lycrea, a land broken into 13 different areas and watched over by the Archangel, The Emissary. The game centers around players creating their character, known as a “Breeder,” who is the only human in Lycrea. The “Breeder” is fully customizable in their gender, appearance, height, etc. Players travel around Lycrea, capturing Nephelyms, a race of monster-human hybrids inhabiting the land. Players can create different breeds in what some players refer to as a “lewd Pokemon-style collection system.” Offspring can have a combination of different traits and have a chance to be born as a “Hybrid.” Hybrids expand the possible species/variant outcomes when producing more offspring.

Ultimate Sex Adventure

As the only one from the mythical human race, you can leverage this to become a Nephelym breeder. Catch wild Nephelym, breed them to produce offspring, and uncover satisfying sexual experiences with blessed Nephelym across the world. 

In addition to sex, you will find a deep lore and story behind this beautiful, but mysterious world.


Every character has the ability to alter their form, color, details, and attachments instantly because they were all created to be dynamic and changeable in real-time. all the while using the same animations and gear. This opens up a ton of options for bespoke breeder construction and gives you a lot of gameplay flexibility when it comes to modifying the form of your Nephelym. Nephelym, for instance, can be given specific foods to affect their numbers and physical appearance, making them either more fit or fatter, depending on your preferences.


There are no cutscenes or loading screens of any kind, and the camera was designed from the bottom up to transition between each mode with ease. You now have more control over your breeder with to features like the ability to take off any or all of the clothes at any time. You are in total control of the camera’s movement and speed, as well as the many stages of any sex scene.

The goal of graphical attractiveness is to increase immersion. There is a lot of vegetation and excellent lighting. Although I have made every effort to optimize, I am aware that this has higher hardware requirements than the typical hantai game. If necessary, rendering quality can be reduced.
