Turtles and Cranes.

In Kunitsu-Game, cranes symbolize women and turtles symbolize men.

An artistic way of communicating men and women. Fitting as the game tells much of the story through visuals.

Soh's dancing talisman is titled 'dancing crane', and when purifying, two cranes can be seen.

Dancing Crane

Congratulations Crane in Otherworldly Venture

Only women(cranes) can use the power of the goddess, hence why only women can be shamans.

Specifically, it is the purifying power that only women can use.

I interpret the kaleidoscope to be implying she is the battery

The masks are all powered by the Goddess Soh. Thus, if Yoshiro falls in battle, they all fall, too.

Cranes are also on lanterns. On the same lantern is what I thought was maybe a lotus but it's actually Rindo Kamon:

Sasa Rindo (笹竜胆), meaning "Gentiana and Bamboo", this mon was used as kamon by the Minamoto clan in Heian Jidai.

So, it is the Heian period!
(As I theorized in my Kuon post and Yoshiro's eyebrows post)

Kunitsu-Gami Detail: Moving Yoshiro around the base!

350 hours into this game, I discovered you can move Yoshiro around! (Funny enough, I always said 'I wonder what R1 does in the base) but never remembered to try...

I kept taking photos of her at the damn tent!

Look at her cute card!

The scenery is beautiful!

Here's Soh's card, too! (It's a sticker from the devs)

Soh's scenery is a bright full moon with a sword. Hmmm.

Yoshiros' field symbol:

Cherry Blossoms. Yet her Spirit Stone body reveals plum blossoms:

Upon looking even closer, maybe these are cherry blossoms? If we consider cherry blossoms are grouped together, then maybe these aren't plum blossoms? But they resemble plum blossoms more...

They actually look like a cross between plum and cherry.

Once you direct Yoshiro, she will give a little nod and make her way, very slowly, to where you've marked. It's quite relaxing to just walk beside her.

Soh is not the 12th mask.

On the saving screen, the stamp with musubi shows the 12 masks. 

I got excited, thinking Soh's would be at the top...only to realize I have been miscounting this whole time.

For some reason, I kept counting Soh's mask as part of the 12.

It's not!!

Upscaled by AI

What's wrong with me!! How did I not count correctly!!

I wrote several posts speculating about the '12th' mask!

+ I have caused my own confusion in speculating about this '12th mask'!!

How could I have let such a simple thing get overlooked? I played this game 14 times!

I think I made the mistake because they always say the 12 masks of the Goddess and I automatically counted Soh's in the 12... 

I am a fool... :( and I feel really embarrassed...

Soh's Menu Outfit + Yoshiro.

I wonder why Soh in the menu is in this outfit, the 'Depowered' outfit. Was it meant to be updated?

I call her Pajama Soh.

There's extra icons on both of their portraits if you put them in costumes.

And you'll also see when Yoshiro is in the mikoshi.
