Om dette spil

‼️This game contains violence, gore, and extreme content. Please read and play with caution.‼️

Unknown time. Unknown place.

The moment the nameless girl opens her eyes, her destiny is already set in motion. With no prayer nor blessing to guide her, she steps alone into a colossal ruin choked with deranged machines.

After unbearable despair and the unending cycle of slaughter, the wavering blue light of her will is shattered, stolen, and trampled again and again, yet she continues forward.

Between cruelty and salvation, the tolling of the Church’s bells cuts through the world, and as their maddening echo strips away the last restraints of flesh and mind, the world begins to shift.

In the depths of this nightmare, she sees it:

Two souls appear, reflections of each other's shadow.
"Are you ready to make the ultimate devotion?"

A dark fable of existence, annihilation, terror and pleasure

Protagonist

CV: Momoka Kosuzu

A girl who has lost both her name and her memories. To fulfill the mission entrusted to her, she explores a vast ruined city while battling the many hostile entities created by the organization known as the Church: a group that once reshaped her body into a living weapon. Each fight sharpens her skills, strengthens her body, and leads her to new and powerful gear whose potential she gradually unlocks.

By following the memory fragments scattered throughout the map, she draws closer to the truth behind this devastated world. The companions she meets along the way give every step she takes through the ruins real meaning. In time, those connections will become the signposts guiding her toward the "end of fate" that awaits.
