Could you link non-trailer footage of Ava's Japanese voice, please? I tried to check for videos of Back Cover's footage in Japanese (like a few scenes), but couldn't find anything that wasn't a) the whole Back Cover in one video and/or b) just the English cutscenes. I think technically, Sephiroth did get a black wing after becoming Safer-Sephiroth (see this Creative Uncut link: https://www.creativeuncut.com/gallery-01/ff7-safer-sephiroth.html). Also, I think Riku was simply leaning on a part of the architecture in the Final Mix cover (which as a black wing design). With a lot of Missing-Link being brought into Kingdom Hearts IV, I hope the game credits the whole Missing-Link team for their contributions. It was the "crystal-like object" that clicked something in my head: What if this Keyblade is related to Atlantis? The lava themed blade is in relation to the volcano that the expedition team found themselves in before finding Atlantis itself, and what set up the final battle and climax of the film. The water is in relation to how Atlantis is underwater, and the "crystal" (although points could be taken away because of the "circular" description) is tied to how crystals are a massive part of Atlantis' culture and livelihoods. This was a nice read into the trailer, Snakeskin94.
