"Wait...what?"

(Meanwhile...this trainwreck is 7′6″

So she’s a giant.

(In terms of the main Other Selves, Yui considers them “family” in a sense, so most of the cast she’ll refer to as her “Aunts” [EX: Aunt Rock, Aunt Saw, Aunt Chariot, Aunt Strength, etc.] this also applies to the other Apostles in the game universe, and she’ll even refer to Stella, Nana, and the Grays as Aunts, even though they’d be more akin to her sisters really, but that’s a little aside the point.

“I can’t think of anything that isn’t candy!!”

Yui it’s been like 3 days...

“Waiittttttt...”

“She doesn’t want candy?”

“Woah! What happened to your eye?! It’s on fire!”

“....So is yours...?”

“Got a question for you.”

“What’s heavier? A kilogram of steel, or a kilogram of feathers?”

“...”

“That’s right, it’s a kilogram of steel!”

(White pupils, with white concentric rings around them, the Anime implies that most don’t have vivid colors or lines, which have to do with either emotions or being connected/fully aware of your human counterpart or something like that.

Yui isn’t an exception, when she isn’t trying to hide them for a more human look, they’re the exact same, just one is green and the other is purple, they’re also luminescent, meaning the whole eye glows a little, and the white pupil and rings glow a lot.

I assume they don’t always have to though, and can be dialed back, since you have shots like this where it’s not as intensive:

But also shots like these where it is:

“Look. I don’t mean to tell you how to be a mother, but why didn’t you try to save your wife and daughter?!”

“My what and my daughter?”

“Wait, you mean you two never got married?”

“What is that, some kind of food?”

“No just, listen...when two people love each other...”

“Oh wow, I’m just fucking with you, my god who doesn’t know what marriage is?”

“Also, “love each other”?”

“Th-they um...mostly just laugh at the stuff that happens y-y’know? Tripping over myself, hitting doorways. All that.”

Something vaguely familiar from your world, humans have then too it seems, though they’re a lot less scary than the ones some Other Selves carry, and have a lot less capacity. 

(90% of Yui’s life is just one half of her body being like “Ya’ll mind if I-” and the other half being like “Excuse you no you cannot.” and so she’s stuck in the middle.

It’s why she can have drastic changes overnight or over time that she has to reign in, like I mentioned the big hands but it can get even worse, things like sprouting horns, bone wings, her hands actually becoming said bone claws, her hair color changing, usually along the choice of purple, black, green,  or white, her eye patterns changing, her voice changing, and even her height changing to be taller or shorter.

All of this is completely involuntary, it’s just an indication of if her Alien genes are winning the battle at the moment [meaning she has more alien influences like her white or black hair and her eye flame presenting itself a lot more], her Other Self ones are [Purple or Green tinted hair, claws or wings or horns, pale white skins sometimes with a green or purple tint, etc], both are equally cutthroat [aka really messed up shit like she has both white hair, with purple or green streaks, maybe a single horn or bone wing, weird half one half other things], or they’re chill [she can actually present as a not completely fucked up human].

(In case anyone’s curious, no, Yui’s not really meant to be this tall, Dead Master is around 5′3″ without her horns being measured, which I hc add about another foot and some change if counted.  

We’re not really sure how tall White Rock Shooter is, we know she’s the same height as her clone Stella is, but it’s never really given how tall Stella is, just that she’s shorter than the humans she’s around. But I can’t imagine it being higher than 6′0″ as best.

Yui’s stupid tall because of hybrid complications and because her body has no chill, basically the theme is that both halves of her make-up are sort of in combat with one another, since Other Self traits are aggressively dominant but Alien traits are stupid adaptive and change so they can’t be repressed.
