I'm the Only Player in a Soulslike World

The rulers are losing their reason. Dark hounds bare their teeth, and someone has disturbed the torch of reason. Chaos is about to spread across this land. O firestarter, before the light collapses, go and redeem those who have sunk into suffering. … Just after transmigrating, Mir is told that his noble family has gone bankrupt. This is a supernatural world filled with monster-infested secret realms. There are even monster cities and villages fused with the world itself, and some secret realms are only half-formed. But Mir discovers that this so-called supernatural world is actually being invaded and assimilated by a Soulslike game. The supposed secret realms are really just dungeons. Yet the supernatural beings in this world seem to be players who have only half-awakened. Their abilities are incomplete: they can't see information about other people or items, and they can't become players, or firestarters.
