Personally, I'm most worried about the plot. As an author myself, I can honestly say that while ARC-V had its moments, overall the plot was a mess, and I really hope that VRAINS can do that better. The basic premise sounds full-on AWESOME so far, with Yusaku going all Kamen Rider as Playmaker and acting like a vigilante to defend the secret world of AI (that's another thing that makes me very happy; VRAINS isn't taking the stereotypical route of 'all AI are evil' and by the looks of things there'll be at least a couple of recurring AI who are good people and help Yusaku/Playmaker). Honestly, if there's one thing I'd like to see from VRAINS, it's a plot where there's no supernatural elements whatsoever. (And a female protagonist, but that's already out of the question, so nevermind) There's so much room for flexibility within the virtual reality environment, so, this time around we don't NEED an evil demon god who wants to fuse all the dimensions into one (something that Yugioh seems to suffer from a plague of . . first Yubel, then Don Thousand, and then Zarc). We don't need magic, because sufficiently advanced technology is indistinguishable from magic, and VRAINS looks to have that in spades. Say, just as a hypothetical based on previous seasons, there's a group of cards a la Signer Dragons that have anti-viral programs installed in their profiles, and these anti-viral cards are the only thing preventing an evil AI (I don't have a problem with evil AI themselves, just the stereotype that ALL AI are evil. If VRAINS has both good and bad AI, I can live with that.) from taking over the Duel Link and trapping everyone who enters in the Duelling Matrix. And one of these cards is Yusaku's Firewall Dragon, and large parts of the plot revolve around parties good and evil attempting to locate and retrieve these anti-viral cards, both inside and out of the Duel Link. Bam, completely workable plot that doesn't rely on interdimensional voodoo. If VRAINS can deliver something like that, as well as a well-written and thought-out narrative, then I'll be happy.
