I can tell you that as a fact.

Sirzech's Sword - Erathaol Mihr Zuriel, Ruined Blade of Desecration: Forged by the Archangels of Old, the sword was wielded through the ages by the Gremory Family until it was given to Sirzech's, who passed it on to Rias before his death. The single edged blade is unable to be dulled or will it rust and become corrupted by time. The main power of this blade is that it will glow a bright purple when Demons and Wraiths are around.
