From the stream recording, the characters on each of the new stages seems to be:
Youkai Mountain - Sanae, Suwako, Kanako, Aya, Hatate, Hina, Nameless Kappas, Aki Sisters
Tao Temple - Yoshika, Seiga, Komachi, Eiki, Primsrivers, Youmu, Yuyuko, Soga
Earth Spirit Palace - Utusho, Rin, Satori, Parsee [This amused me for some reason, seeing as both are rather hated], tons of animals
Forest[?] - Sunny, Luna, Star, Cirno, Lilly White, Utusho, Rin, Aki Sisters, Shou, Satori, Sanae, Kyouko, Suwako, Kogasa, Tenshi, Iku, Hina, Wriggle, Parsee [OK what are you of all doing above ground?]
Night Forest - Tanukis
Final Stage - Humans
Planquin Ship: + Tenshi and Iku
Futo's stage - Letty [?!], Yuuka, Rumia, Sunny, Luna, Star, Cirno [With Letty ofc], Medicine, Mystia, Wriggle, Lilly White
Myouren: Shou, Kyouko, Kogasa, Nameless humans/youkai, Aya, Hatate
Post PC-98 characters who do not appear: Momiji, Yorihime, Toyohime, Kotesu, Reisen II Lilly Black, Yamane, Kisume *
Apparently Momiji, Yamane and Kisume are hated and forgotten. [Lilly Black may or may not be Lilly White]
Also a few other crowd things of note:
1: Apparently Letty doesn't vanish when it's not Winter anymore. In fact, her and Lilly can exist at the same time, apparently.
2: Sanae is pretty much the only crowd character other than Yuugi with a visible bust. She's also pretty tall, and looks early 20's tbh now. I find this particularly interesting considering the likes of Yuuka and Komachi seem rather flat. Of course, characters further in the background are harder to tell than with Sanae... who's in the forreground. And bouncing up and down. DAMNIT SANAE. Oh, and Nitori's flat despite her being one of few characters to ever have any bust at all in ZUNART.
3: Rumia apparently has better control of her powers. She's not made everything dark.
4: Kogasa is still moe.
5: Apparently relations with below ground have got to the stage where Satori can come above ground and not be lynch-mobbed for mind reading powers and being a Satori. Not to mention Parsee...
