How many character references are in this? Byakuren's script is in the background. There's a giant frog, fans and autumn leaves near Marisa's broom, sunflowers, Higan flowers, various youkai and animals. The emblem near the ice confuses me though.

Kanako's onbashira? A Hakutaku, a kappa, a karakasa... Not sure of the monkey though.

There's a dragon there too, looks like.

i see Nazrin, ExKeine, Reisen or Tewi, Kogasa, Byakuren,
Meiling, Suwako, Aya or Utusho, Shou, Nitori, Chen, possibly
Cirno and Kanako, and Yuuka. I cant quite find Marisa though

I see the Aki sisters and Yuyuko in there too.

I know I’m a bit late here, but I just want add a suggestion. This could just be me but I think the ‘monkey’ might be Satori. If you search for images of the satori youkai they look ape-like.
