I transmigrated into a highly notorious, dark fantasy adult game (Eroge) known for its unforgiving difficulty and incredibly tragic "Game Over" states. In this world, if the main story proceeds according to the original plot, the beautiful main heroines are destined to face horrific, corrupting fates at the hands of villainous factions and monstrous entities.

To save them—and to secure my own survival as a weak, low-ranking extra—I decided there was only one logical solution: I will systematically monopolize every single main heroine before the plot even begins.

Using my flawless meta-knowledge of the game's hidden events, quest lines, and character triggers, I intercept the heroines at their lowest points. I rescue the proud Holy Knight before her fall from grace, cure the Elven Princess of her forbidden curse, and secure the absolute loyalty of the brilliant Mage Academy prodigy. I hoard all the legendary hidden items and affection points for myself, completely erasing the original protagonist from the picture.

As I completely derail the dark storyline to build the ultimate, unyielding sanctuary, the heroines become intensely, fiercely devoted to me. While the villains are left utterly bewildered as to why their carefully laid traps keep failing, I find myself ruling a monopoly over the game's strongest and most beautiful women, turning a dark, tragic world into my personal, exclusive paradise.
