This is a leaked scan of Yuuki Gai (Black Condor of Jetman), shown here with a mobirate(?), which official confirms that he will appear in the Jetman tribute episode sometime in September. The actor, Wakamatsu Toshihide, confirmed this several weeks ago from his blog.
He is among a growing list of confirmed returning actors, which includes Nishimura Kazuhiko (Ohara Jo/Yellow Lion of Liveman), and according to some rumors, both AbareBlue and AbareYellow!
