I can't deny that although he's already in his 40s, he still has maintained his build and power. Oh yeah, who did he marry in real life? Keiichi Wada did fans a great favor by appearing in the Gokaiger movie and in this episode. What's cool is that he owns a Chinese restaurant. Oh boy I'd like to eat there someday!
The episode was purely fan service for Dairanger fans IMO. BTW I wonder what Kou is doing now that he's an adult?
