Keller and Mirror (ケラー&ミラー Kerā to Mirā) are female spies in silver and gold respectively. Keller can change into a shield, and Mirror a vanity mirror. After Demon King Banriki took control of the Vader Clan, Keeler and Mirror conspired with Queen Hedrian to kill him. Keller died during the assassination attempt, when she turned herself into a shield to protect Hedrian from on coming daggers. Mirror pretended to be loyal to Banriki, but assisted Hedrian in helping the Denziman defeat Omnipotent Monster. After its destruction, Banriki confronted Hedrian, but using magic, Mirror blinded Banriki. In a blind attack, Banriki struck Mirror with his weapon, killing her.
