Awaken the taboo existence and fight against the unknown disaster; welcome to the school, "Secret Keeper".
The world is dying. Hundreds of years ago, the phenomenon known as "Melt and Erosion" emerged silently. Life, reason, memory—everything that humans have imbued with "meaning"—is being gradually erased, leaving no trace of their existence. And yet, people remain oblivious to this encroaching doom.
Faced with this secret and unspeakable disaster, Missaga University, as one of the few entities aware of the truth, is committed to awakening a power that shares the same origin as the disaster. They aim to connect with humanoid weapons teetering on the brink of madness to combat this monumental crisis.
If everything will eventually be forgotten, are you willing to carry the secret and move forward as proof of the world's existence? The tombstone stands as evidence, and may the silver key guide your path forward.
Welcome aboard, Keepers of Secrets. Living in foggy England, you carry the secrets of the times, navigating through life and death. Amidst the melting crisis, elegance and power intertwine.
Assemble your own card lineup and awaken those who share the same source of disasters. Navigate through roguelite levels, using strategies to uncover taboo truths. Experience a unit-style plot as you pursue the truth in a fractured world.
