I've checked all four of his screenshots very carefully. They've definitely been edited.
This one shows it pretty much. It's composed of one screenshot, placed on top of another, with 50% opacity in Photoshop. The letters clearly do not match up.
I think I found the mage too. Res, you didn't check all the way to 170. xD But this is the only dragon I found with a name ending in nHa. Ken's screenshots have been edited majorly, because his actual IGN contains 10 characters, and the name he tried to show us obviously looks too short. I don't know if this is simply to stop us from finding his char, but once we know the level, you may as well stop hiding it. O.o
I blurred out the rank # and some of the name. Have fun looking guys 8D
edit: Usop, stop being a ninja.
