Either way it's a liscenced game, just from Bandai Korea. (Like how all star rumble and fusion fighters was Bandai USA.) Also Habu said before the media vision team are responsible for the current set of 3d models (tho Bandai own the rights to them which is why they've been reused in other games). Not sure how that would work with Ruin mode but I guess technically the links staff recoloured the media vision model of Burst mode.
It'll be the same situation here, models made by game king or whoever but owned by Bandai Korea. (Will also be why they got to reuse the soul chaser sprites after they took over since Bandai Korea would own those)
