Asmodeus is the treasure of the House of Flaming, as it has been passed down for generations, from ancestor to another. It was the blessing of the house while it was sealed. The wielder of the sword becomes the next head of the House of Flaming. The sword's curse sometimes turns it's wielder's hair to red or vermilion in Arnest's case.
Asmodeus is possessed by a demon, able to manifest itself before the wielder in a form of black smoke and speak to them, though it is unknown if others can see and/or hear it as well in that state. However, once inside the sword's world, the demon Asmodeus manifests himself in his true form. The demon would entirely possess the wielder if they don't have an iron will to fight it, something that the Flamings' conveniently developed.
