Well, Lic has a savage side we never knew about.
So, I hadn't heard anything about this Airborne Brigade event (actually, I didn't even know that shitty game was still being updated, to be completely honest), but I looked into the details. It's actually pretty Clerith-centric, in that the chance to earn a Groom Cloud card came in the same event on May 31 that saw the release of the Bride Aerith card.
As notable, there's apparently a cute cutscene -- or what qualifies for one in this game -- in which Cloud gets down on one knee, holds up his hand, and then Aerith squees. She also throws her bouquet at the end of the event.
Oddly, they're both already in their wedding garb in that proposal scene, but my guess is the thinking there was to get the most use out of these designs made specifically for the event.
The Bride Tifa card became available June 6. There aren't any cutscenes between she and Cloud, but there is one nice little Cloti thing in that in each of these three cards, the characters are holding items made of or adorned with the same flowers -- a bouquet for Aerith, a sword-sized cake knife for Cloud, and a wedding cake for Tifa. Each of these "weapons" also have their own cards. The Wedding Knife and Wedding Cake weapons obviously form a matching set even as both remain connected to the Wedding Bouquet by their shared flowers.
The Clerith depiction is definitely dominant here, both in the event's advertising and in its content, but both major FFVII pairings get attention -- which, being a polyamorous person myself, is a particularly nice thing to see in the context of an FF wedding. I like to think that such a dynamic is what would have emerged in FFVII proper if Aerith had lived.
Those graphics, yo. Hope they use that Jenova model in the remake.
