Yeah, if it is something like that Zahard would have to mention it soon.
I hadn’t noticed the butterfly design but that looks EXACTLY like the FUG design and considering that the flare wave (or butterfly) is FUG’s technique it either comes from V or Arlene. I suspect it comes from V though since this arc has been all about Bam’s connection to V.
And we already know that shinsoo qualities (I am assuming elements like Jammin suggests) are inherited like ice and fire have been, so it’s not s stretch that Bam’s would be similar to V’s.
If Zahard is not a complete idiot then he should recognize that shinsoo and he should know exactly who Bam is now.
If that is what the FUG symbols are taken from then V would make the most sense as an origin point since wasn't Arlen hinted at being a spell specialist. V supposedly had a great tension so that would mean he'd lean much more into the shinsoo quality side of things.
I'm pretty curious what the true nature of this shinsoo is going to be. We've seen a lot of visual elements assosiated with it. The sort of demonic look with the dark shinsoo and horns. Yet inside himself Baam presented it as a white line. But when he used it as an attack it was red and black with a butterfly motif. So there is a lot going on there.
