Princess Mamoru Moonshine Jagermeister Jack Jack Daniels Timothy Tim Bill Freddy Mercury Blueberry Luna, Esquire was an ebon-turned-blue devil that was formerly named Vladok. In his introduction, he was noted as the grandfather of Dhuutholmel (in a spiritual sense).
As Vladok, he accepted Allison's request to "take [her] to the magical floating castle" belonging to Mottom if she would wager her Key of Kings in a drinking contest. After losing the drinking contest, he broke his contract and became an unbound devil until she was re-masked and bound with several names into a much weaker blue form. As Princess etc., she is now among Alison's companions and defenders.
More recently, this devil shed many of its names to become the red devil "Princess Jack Moonshine".
