To Save a World That Won’t Remember [Isekai / LitRPG / Progression / Horror]

When an ancient enemy’s rebirth is only eight years away, the first king makes an unthinkable pact with a Demon God. In exchange for summoning a hero strong enough to face the coming darkness, he sacrifices not only his life, but his name, his memory, and his place in history. As the world quietly reshapes itself to forget him, fragments of the king’s hidden memories remain, scattered and sealed beyond reach. Only the summoned hero can find them—echoes of a man who no longer exists, guiding a fate no one understands. With time running out and the past erased, the fate of the kingdom rests on a truth no one remembers—and a sacrifice no one will ever know.
