Based from one of the page when Ryuzin is almost getting uncontrol himself again, well , it still far , maybe episode 14 or 16 something XD. Just wait and see in the my comic series .

Just you can see, there were a dark colour starting to appear on Ryuzin body, well, actually i don't know or don't have any idea how to make Ryuzin transformation into Phantom Dragon.
Maybe this is my first step.

Enjoy~
