Spirit Stone Yoshiro's Body and Cursed Soh's Body.

Defiled Yoshiro≠Cursed Soh: The Spirit Stone and previous misconceptions.

Building off this post...I noticed something when looking very very close at Yoshiro and Cursed Soh.

I mentioned Yoshiro's Spirit Stone body is to protect her from impurity. There's very faint kaleidoscope patterns on her!

It looks exactly like the sky in the Unknown Land, too.

(PS4 isn't very high quality so I can't get good photos. It's also why I didn't see the pattern at first. That and the lighting made a huge difference.)

look at her glove, too.

Cursed Soh also has these patterns all over her. It's a symbol of the power of purification(or the Goddess) because we see it in Soh's attacks and when she makes her appearance. 

Another detail: Soh has a fox on her glove. Does Cursed Soh have a nine-tailed fox? Is that what those shapes could represent?

Cursed Soh, the Goddess, is trying to protect herself from impurity and has possibly turned her body into Spirit Stone?

Or is it that the Maidens who become these things and have merged with the Goddess has caused her to turn into this?

When Yoshiro's hair turns pale lilac/grey, we get the scroll 'Birth of a Goddess', signally she's become like the Goddess. Or has merged with her.

She indeed looks like Cursed Soh.

When the pair sync up Yoshiro's movements sync with Soh's, not the other way around.
Yoshiro is becoming like Soh(Cursed) but because the lines have blurred due to Maidens being worshiped as the Goddess, Cursed Soh in turn became like her. (The long hair and outfit changes)

I talked here about the Goddess's behavior when encountering Soh and Yoshiro.

Another detail that rattles me:

Cursed Soh's footwear is symmetrical, unlike Soh's.

But in artwork, it's symmetrical:

A very deliberate change. But why?
