[TOMT] lost Ghibli Sericel (Pic in comments)

At a thrift store I found this cel claiming to be from princess mononoke. Looking at it further though it’s clearly from Katsuya Kondo’s PS1 game Jade Cocoon. I cannot find any information about this print and I’ve searched the internet looking through message boards, eBay, and even asking chatGPT.

My theory is this was a promo given to American magazines or stores for the American release but I’m desperate for more info on this seemingly nonexistent piece of art. Thank you all so much.
