[So this guy's been performing on various Japanese superhero shows from a very young age, with his earliest roles being something along the lines of "kid the monster of the week was targeting." He's settled in nicely to his role here, even if he's got a reputation for playing pranks on the set. That was what that "Joker" thing he'd auditioned for in the first place meant, right? He seems to think so.]
