Gatekeepers 21? I treat it the same as Macross II; to me, it doesn't exist lol. And even if it did, I'm treating Ayane as the product of a one night stand from Shun and her mom when Shun was terribly depressed about the disappearance/death of Ruriko. Speculation? Hell yea, but I've been part of a group known to be 'delusional', so whatever...
RurikoXShun FTFW... end of story lol.
