Fanon meme/thingers on Yuma's personality because I am anal and unused to playing an adult.
Fukiya Yuma and Torii Saya get screentime twice in the manga--in book 4 and book 6, with cameos in book 5, and in an omake special as well. They get no time at all in the anime. Soooo there's not a ton of information to work with, and we have to extrapolate quite a lot for camp.
The first time they appear we get a taste of their 'normal' personalities. They're shameless, cheerful, and fun with no sense of personal space. They coo and fawn over people, they don't say uncomplimentary things, and they're willing to TALK ABOUT THEIR CUP SIZE IN VERY LOUD VOICES WHEN THEY KNOW PEOPLE ARE LISTENING.
Their second major appearance...apparently they're there to help Tsuzuki and Hisoka out on a case, but after a couple of chapters (and the infamous Hisoka-inna-dress-panel) they kind of fade into the background. Boo, Matsushita Yoko. Boo. But we get a bit more here: they really don't like the heat, for one. They also get a more serious side shown--for awhile, they're not smiling, they're not fawning, they're sitting together and they're quiet and thoughtful. And then when things get freaky, Saya is revealed to be afraid of ghosts (...what is the logic there?!) and meanwhile Yuma gets a 'rawr' face and does the 'J-ACCUSE' pose. She's more forward, kind of.
And from there, we go to my portrayal of her personality:
- Yuma is, if this makes sense, not as nice as her partner. Er. Comparing threads, you can kind of tell Saya's sweet and innocent and nice to people, and when Yuma talks to those same people later she does the sweet and nice part fine, but the innocent isn't there and it's more...tactful.
- Yuma also covers up a lot--she's not as open as Saya can be, in that regard. I'm not talking about their job, because it's common sense that they keep that secret. Um. If anyone but Saya (and maybe the other people from EnMaCho, but it'll be WAY awkward) tries to get her talking about her life before becoming shinigami, she'll probably dodge the question or start talking about work instead. And she doesn't want people to see her sad, just like she hates seeing anyone else sad. Check the Letters From Home post as reference to that: Saya actually did write a note to her mother, in the end. God, that was an emo moment. Yuma wrote more or less an undercover report for the Chief to inform him where they were and what had happened, and yes, it was a report, despite he pretending the Chief was her big brother and all the heartmarks that got pasted into the thing. That's the way she works.
- When she gets annoyed or angry (which is hard because she's quite tolerant, but you can do it by being completely rude and destroying things like Kimimaro did), Yuma goes and does a Hakkai. Or something similar, anyway. The way she talks will become almost excruciatingly sweet and happy-sounding, but she stops heartmarking and tildes appear at the end of every sentence and she'll most probably be using the 'creepy homicidal smile' icon repeatedly. Those are danger signals. They mean 'I AM GOING TO SMACK YOU SOON BITCH.'
- In times of real and obvious danger, Yuma is all business. Away go the 'UWAAAAH's, and the laughter, and the dresses. Out come the ofuda. She doesn't fool around then, and she's very capable of taking charge and doing her job. She and Saya have also worked closely together long enough that they pretty much know what the other will do and work with it.
- Yuma can also be sneaky rike ninja when she needs to be. See the Letters From Home thing above. She can keep secrets, she can analyze. There's a pretty good brain behind the fashion-conscious fangirl, and she uses it.
- She cannot imagine an afterlife without Saya. They're--they're partners, and they're always together for a reason and there's something there. In-camp they're being all ambiguous about their relationship and stuff, but they don't really need to be. The relationship might not be romantic, but they're pretty much as close as lovers, or sisters. Both.
Going from there, she works in complete conjunction with Saya--their abilities are about on par--but if it comes to a split-second decision she will immediately sacrifice herself to save her partner.
- She likes cute and pretty things. Wait...this isn't fanon. That she likes children very much is. Player theory: she wishes she'd lived long enough to have a few of her own, and so she'll pretty much mother and be very, very sweet and open towards anybody who goes shouta, even moreso than she is towards adults.
- I'm still very much willing to bet that Yuma died taken by surprise in a really cracky way (Saya-mun and I think that it might have involved saving kittens from trains), or that she was murdered. Don't look at me like that--all the YnM shinigami are shinigami because they have issues of some sort. S'truth.
::EDIT:: Okay, Saya and Yuma now have some sort of backstory. In other words, their players made stuff up in order to prove that they weren't test tube babies. See here for their 'deaths' -- Saya's was accidental, and Yuma got murdered by Emilio's naked her brother. ...we kinda agreed in IRC that this is one reason Yuma is the 'less innocent' one of the two.
And that's all for now. See? The Hokkaido wonder twins really are different people! 8D
