What percentage range do you think this series has of featuring new demons from Chinese ethnic minority myths(especially those ethnic minorities that have never been seen before)? i think that most works about chinese myths neglect those groups. it would be great if we get demons from hmong,nuosu(yi),manchu,qiang and more. (you can check about nuosu book of origins. very crazy)
Do I really even need to answer? I think you already know.
The Nuosu Book of Origins is at least currently available on the Internet Archive.
The most obscure demon in Megaten with a verifiable source remains Tingkat. It will likely never be out-obscured. And it's only in Soul Hackers thanks to Shigeru Mizuki, who was a mainstream source in Japan for these obscure creatures from around the world.
Demons from the myths of these obscure ethnic minorities are improbable in this era of SMT because:
they're unlikely to result in palpable hype/excitement for the game (people who are not hardcore myth nerds, i.e., the majority of SMT's audience, are not going to rush to buy the game because Y they've never heard of from X myth system they've also never heard of is in the game--this is the "demons as promotional material principle.") This of course unless Doi can make one into a HOT BABE with like long legs, a huge ass, wide birthing hips, and classic FFs overflowing from a skimpy top. Never underestimate the gooner Doi principle.
The "Lone Wolf" principle--It wouldn't be very exciting or meaningful if one of these obscure myths gets added with a single design/demon, because, you know, new roster slots are scarce these days. How is it going to interact with the greater, established SMT demon roster? Nuosu demon Y would, at best, be forced to spend eternity accompanying mainstream Chinese demons like Nuwa or Zhong Kui, and that wouldn't be much fun, would it? It's like a Hydrogen Bomb vs. Coughing Baby situation within the greater SMT framework.
More to your point, SMT is no longer a series where many dozens to hundreds of demons are added for every game. At most we get perhaps 2 dozen now. If this were still 1997 and there was no need for the majority of the new to be plot-relevant...maybe you might see one of these.
