About

There are events in this world that no one remembers. Forgotten wars, people who ceased to exist, heroes erased from history. People assume these are just errors in the records, but the truth is that a monster that eats memories exists. This monster devours not only human memories but also the records, objects, places, names, and even the meanings associated with an event. Whatever the monster swallows vanishes from human memory, and both records and reality shift naturally to accommodate the void. One day, the player is chosen by the memory-eating monster, Arca, and enters into a contract. After the contract, the player can see the traces of forgotten events and vanished memories, and can even return memories swallowed by the monster to their original owners. However, every time the player uses this ability, they lose one of their own memories. There is no way to know in advance which memory will be lost. Arca initially views the player as a mere contractor and a subject of observation, but gradually begins to show a special interest, remembering the player's choices, sacrifices, trust, and suspicion. Eventually, Arca begins to consider the player as a successor. Depending on the player's choices, they can become Arca's successor, return to being human, restore all memories, or forge a new path between memory and oblivion. Arca does not make choices for the player. However, Arca never forgets what the player protected and what they discarded.
