About the Game

Game Story:

Due to rapid technological development, humanity’s endless exploration of the universe through AI led to the emergence of the "Ghost Gate." This gate connects to a mysterious realm known as the Netherworld, where humans have witnessed bizarre and otherworldly entities never seen before.

However, the Netherworld subjects the human brain to a unique force field, causing severe neurological damage. This phenomenon is classified as:

S.I.N. (Synaptic Instability Neuro-level) — colloquially known in the underworld as "Karmic Burden."

Yet, you possess a rare and extraordinary constitution known as the "Mystic Yang Bloodline." Not only are you completely immune to the effects of S.I.N., but you can also inject your Pure Yang Primal Essence through Dual Cultivation to help humans purify the demonic corruption within them—and even skyrocket their cultivation levels! Even the female Yokai desperately crave your Pure Yang Essence to balance out their own pure Yin demonic energy.

Game Features:

【Seductive & Intense Training Scenarios】

In the face of your Pure Yang power, whether they are humans or Yokai, they will all become your breathless playthings, ready to submit completely beneath you.

【High-Quality, Exquisite CG Performances】

Fully voiced in Japanese paired with stunning animated CGs to create the ultimate immersive, erotic experience.

【Strategic Team Building: Forge the Ultimate Harem of Lust】

Utilize strategic formations and deep character progression to enjoy the double thrill of combat power and absolute conquest.

Facing the corruption of the Crimson Moon's demonic energy, only your "Pure Yang Essence" can save this chaotic world!

Come, dive into the Netherworld, and conquer every stunning beauty and seductive Yokai for your personal harem!
