In the game “Eden’s Crusade,” there exists a hidden route no one has ever completed.

A gamer obsessed with discovering it awakens as Flora Alberich, a soulless vampire girl sealed deep beneath a noble mansion—treated not as family, but as a forgotten monster.

But something is different this time.

Flora is awake.
Flora is sane.
And Flora remembers everything.

Reunited with her overprotective “sister” Carsella, ignored by her cold mother Lucrezia, and reluctantly aided by the mysterious mage Elisiel, Flora begins to navigate the twisted dynamics of a fractured noble house.

But this is not just survival.

Using knowledge from the game’s hidden routes, she begins to rewrite the fate of the Alberich household itself—exposing secrets, breaking delusions, and slowly reshaping the people who once sealed her away.

Yet as affection turns obsessive and family bonds blur into something far more dangerous, Flora realizes:

This hidden route may not lead to freedom…

…but to something far more irreversible.
