I mean...again...they're just following Crystal... If they were really trying to follow the manga, Mars and Jupiter would have their accessories and manga hair color.
Anyway, given the plot, I think it's safe to say we won't be seeing Wiseman, Ail and En, Pluto, Chibiusa, or anyone else besides the Inners, the youma, and probably Tuxedo Mask.
Anyone know if the Crystal voice actors are voicing this thing, or might there be a chance of some different VAs being involved? I'm assuming it'll be the Crystal cast, but I'd like confirmation?
