A Mystes(ミステスMisutesu) is a Torch that has a Treasure Tool inside of them. A Torch becomes a Mystes by random chance, and the process happens the instant that human becomes a Torch. Most of the time, the Torch does not become conscious of the Treasure Tool residing inside them, even when the individual dies. At the death of a Mystes, the Treasure Tool travels to another human who has just acquired their Torch status and this process of transferring a Treasure Tool from one Mystes to another goes on until the Treasure Tool is extracted from the body of the Mystes.
