^ I thought the same as this guy. It would fit just fine if he was Ul's husband and he mourns at her grave and he started killing demons because a demon killed his wife and etc. It would be silly if he was Gray's father but it could be that way so...we can only guess. He might actually have nothing to do with neither of them so...yeah.
