Culled this from a site who quoted Famitsu mag:
This especially powerful Judge is known as a "Judge Master," and has the ability to read people's minds as well as summon powerful espers. He's wrapped in mystery, but looks to be related to the winged people of Lumures.

How about ESP and necromancing thrown in there for good measure? There's really not much out there about this guy. I'm not looking forward towards RW, however, from the badass armor he's got, he better be nothing less than badass in battle.
