Yeah, aside for the fact that Masaki and Ryuken were supposed to be married, there are no relations. About being blood related in any way wouldn't make sense since Ryuken is marrying Masaki, I recently read the Quincy page. They arrange the marriage of their children to preserve their "Pure" bloodline so incest is somewhat "legal" for the Quincies as long as it is for reproduction purposes.
