There's also the question of Yakushi himself - he said he was in middle school when the show came out. Yet he has a daughter who I would guess is supposed to be 20 or so herself? I don't think Japan is as bad as the US about 13 & 14 year olds having kids, so the math doesn't add up, as D confusedly points out.Yakushi learning about D is not good. Very much so. Especially since he's willing to force D to act like how he thinks he should. And then there's the question of the 20-years-ago TV show vs. the 13-years-ago invasion. Were the invaders created based on the show? Was the show created with foreknowledge of the invaders? That's an interesting question.
