Winter, 2, 7, and 8

Yui, 2: To a certain extent, while less than Haruka, Yui imprints on the picture books she so adores. Good manners, polite, she's fairly nice in general.

But she does tend to be somewhat casual with classmates and friends, but formal with adults and strangers.

That falls apart when she's worried or angry, though.

Yui, 3: Absolutely gets out of other people's way, with apologies. Except when on a rampage, when she goes right through people.

Winter, 2: She's become gradually less polite to people in general over time, that's for sure. She doesn't inherently mind being a good and proper girl, but it's gotten hard.

She's kind to work with until she gets even the slightest hint you're trying to take advantage, then she's prim and abrupt.

She's happy to hold doors and be reasonable, but she's also very cautious these days.

And heaven help you if you have a Cure Diamond hoodie or something.

Winter, 7: Her hands and her eyes. She's very animated when she talks and tends to gesture pretty sharply. Her motions get wilder when she's anxious or angry.

But even when she's shutting you out, her eyes tend to show what she's thinking. When things are going right, they sparkle, and when she's depressed, they're dull.

It's somewhat pronounced, so it's a good judge of her mood. Just try not to set her off, or everyone will know. And it'll get back to you, one way or another.

Summer, for reference, is slightly harder to read but generally follows the same rules.

There's, ah. Also the certain gleam of violence that people familiar with her will pick up on pretty fast.

Winter, 8: The whisper of fabric as her skirt flutters in the wind. Her keys, considering she has three sets.

The quiet buzz of her phone as someone else tries to get a hold of her.

Soft whispers when Lily is around and she's trying not to be too cute in earshot of other people.

Once she's transformed, the click of Diamond's heels, which is something that may transfer to her normal form - I think she's grown to appreciate it more than she lets on.

And, of course, the ring of a tambourine during Diamond Shower.

Winter is in general not really stealthy, but she travels light thanks to the Mirage, and all of her hobbies are quiet things.
