Awaken a forbidden existence to battle an unknown calamity. Welcome to the academy, "Keeper of Secrets."

The world is ending.

Centuries ago—the "Melting and Erosion"—descended in silence. Life, reason, memory, all that humanity has deemed meaningful, every trace of existence, was slowly erased by the erosion.

And humanity remains oblivious.

Facing this secret, unspeakable disaster, Missaga University, among the few who know, has resolved to awaken a power born of the same origin as the calamity. We forge bonds with humanoid weapons teetering on madness's edge to withstand this immense crisis.

If all is destined to be forgotten, will you shoulder the secret and press on—as proof this world once was?

Let the tombstone be your evidence, and may the silver key light your path.

Welcome aboard, Keepers of Secrets.

Dwell in the fog-shrouded lands of England, bearing the era's secrets through life and death.

Amidst the melting crisis, where elegance and power walk together.

Assemble your deck of cards and awaken those who share the disaster's source.

Conquer in Roguelite challenges, using strategy to unveil forbidden truths.

Experience a narrative of fragments, pursuing truth in a shattered world.
