*Rolls a pen against my chin*
Mmm... What would that have to do with the electricity itself?

@Legend

My only thought is that it's due to how cells split based on electrical fields. Maybe they're always trying to split, but they can't without a forced cell splitting. Or maybe it's just a source of energy that gets used to fuel the split. It's hard to know.

How does electricity cause a transformation for her? What about it?

@Legend

I'm guessing it's some form of macro-mitosis. You said that the second one's body formed from a piece of the original's, right?

Myriad Reality

<Snipped quote by Yatagarasu>

Did our older siblings also need electricity to transform?

@Legend

They did not. I'm unsure if that's a coincidence for Shion or not.

Myriad Reality

<Snipped quote by Yatagarasu>

Like you did?

@Legend

That's right. I was lucky enough to know about it pretty early, but I think that's what's going on here. It makes me wonder if it's somehow hereditary, and if so, whether the rest of you kids have something similar. Your elder siblings had the ability to change forms, but they didn't have alternative personalities to them.

Where does it go when she goes back to normal, then?

@Legend

It's probably suppressed. Theoretically, anyone could have a suppressed aspect in them, psychological or spiritual, and never know.

Myriad Reality

<Snipped quote by Yatagarasu>

So what? Shion is really a suppressed lunatic? Her soul grows to fit the body?

@Legend

A partial soul can still maintain a full body, and I don't know that I'd call it that, but in a sense, yes. My hypothesis is that this is a metaphysical phenomenon similar to your mother's, but also psychologically similar to my own splitting, back when I was whole. Even though my soul was... essentially nothing, as it grew back, so did the parts that were "other" to me. I'm thinking this is a similar thing. There's a lot of things we can search for to confirm that, though.

Myriad Reality

<Snipped quote by Yatagarasu>

Even if they're not, then they'd both come from one original soul.

@Legend

I believe that's the case.

Myriad Reality

<Snipped quote by Yatagarasu>

That’s an unknown. Either her soul needs to already be there, be from somewhere else, or get created on the spot. There’s no real other option.

@Legend

If you assume that they're both full souls, yes.

Myriad Reality

<Snipped quote by Yatagarasu>

If Shion only had one soul and split her body, that’d leave an empty husk for any soul to take over.

@Legend

But why would it be the same one each time?

Myriad Reality

<Snipped quote by Yatagarasu>

Could it be another soul harboring her body?

@Legend

It could, but why would it only show up when they split? Why would there not be evidence of it in her normal state?
