Unfortunately, I can say that this Volcanion is very much hacked, or at least it has been modified in some way. All Event Pokemon now come with the "Classic Ribbon" (Or possibly the "Wishing Ribbon" in Japan, though it depends on the Pokemon) attached, and your Volcanion does not. That would be the biggest indicator. But there are several oddities that would raise large flags.
First, as you said, 6IV Legends are very suspicious. Given that RNG Abuse could only be done by a supercomputer in Gen 6 (I'm joking, but seriously, RNG was not a thing in Gen 6), it's hard to assume that someone was able to SR a 6IV version.
Secondly, it's odd that the OT is for the Japanese version, but the text is set for Germany. EU Volcanions will have the OT Helen like the rest of the world, however, the owner could have conceivable been a German using a Japanese 3DS with a Japanese Cart and have gotten the Japanese event by going to Japan and pre-booking for the movie, however, that is unlikely. (Honestly, regions are a bit weird, I'm not sure if changing your language also changes your region, since I don't own a non NA Cart, I'll never know, so this might not even be possible.)
In all, it's safe to say that this Volcanion is not trustworthy, and should probably be released. Sorry.
