So all four Grand Inquisitors are revealed. A few things to note about each:

-Ivan's appearnce and style is like the Diablo 3 Crusader. Big man, big shield and a lot of discipline and training. He's also honor-bound like Granberia. Which is why he respects her more than any other Heavenly Knight.

-The monster Kain's after is hinted at by the location he was introduced in. The locket he wears has a lock of her hair he uses for scent. The Monster however, see's the situation differently.

-Maria has a crush on Adam. She always thought Luka was adorable and would make a perfect playmate, so she's settling with his look-alike grandson because Luka's too powerful to make into a doll.

-Yes, Issac, Mr. Supposedly Can End the World, is a shota. There's a reason behind it that's explained as his backstory is revealed MUCHHH later. Also being the strongest, is Tamamo's "counter."
