Story

Elf siblings Ed and Celica have lived alone together since they were young. Secretly, they both harbored romantic feelings for one another.

Suppressing these feelings, they visit a dungeon for a quest. In the deepest part, they encounter a powerful Incubus who, as mere entertainment, carves a curse onto Celica.

"The Curse of Constant Estrus"

A curse that makes her want to have sex with anyone if a man is nearby. This puts Celica in a situation where she wants to commit incest with her brother right beside her.

To save his suffering sister, Ed reluctantly breaks the taboo. However, they learn the curse can only be lifted by defeating the Incubus, and it grows stronger over time.

Even as Ed fights to save her, the curse forces Celica to mate regardless of place or partner. Delighting in lewd dungeon traps and eventually taking customers at a brothel, the curse erodes her love for Ed, turning him from her beloved into "just a brother" as she falls into depravity.

Game Overview

Play as Ed, diving into a dungeon filled with lewd monsters and traps to break the curse on his beloved sister Celica.

Personality Alteration Curse

The curse strengthens gradually. In the dungeon, Celica can be afflicted with personality-altering curses like "Sadistic," "Masochistic," "Spoiled," or "Big Sister." Her reactions in H-scenes change based on her current personality.

Battle F**k & Traps

Battles with monsters include H-scenes, and defeat leads to scenes as well. The dungeon is filled with gimmicks that induce arousal and lewd traps, all featuring H-scenes.
