About the Game

Summoned by accident to a fantasy world by a priestess named Lyria, something went wrong: someone interfered with the ritual and marked your body with a cursed seal. That mark consumes your Ether, the life energy that keeps every being alive in this world. And there’s only one way to restore it: through shared sexual pleasure.

Embark on a journey to break the curse and uncover the truth behind the supposed “goddess” who cursed you. Along the way, you’ll meet women who will join you and satisfy your desires:

🌸 Lyria – The Priestess

Gentle, clumsy, and devoted. Gains Ether by healing and helping others… though now, healing you gives her pleasure too.

🔥 Erys – The Mercenary Warrior

Strong, proud, and straightforward. Gains Ether through combat and physical challenge—but nothing compares to fighting you in bed.

🕯️ Nyra – The Dark Mage

Curious, energetic, and perverted. Loves forbidden knowledge and the secrets of the body. Gains Ether through the thrill of taboo pleasure and experimentation. She can’t wait to learn how sex works in your world.

Can you uncover all the secrets of this fantasy world and break your curse?
