Additionally, I'm separating Raine from China. They don't talk to each other. :P

-Raine's cultural upbringing is mixed, and also can best be defined as on the run. So, she's probably a bit atypical in that respect. The half-elf thing is reflected in her mana, and since mana and soul are pretty close to each other in her canon terms...
-When canon describes half-elf mana, it's just referred to as strange, and produced by the fusion of human and elven blood. So overall it's probably pretty distinctive. Not one nor the other, and just generally weird. Not wrong, per se, but different enough not to be ignorable.
-Emotionally, hm. Curiosity and the desire to learn are probably strong things. She's logic and cool demeanour all over everything, mostly, but I wouldn't be surprised if the stuff she's inclined to get loud and enthusiastic about shows up somehow. Science. Ruins. Learning. Magic. Etc.
-She's missing the majority of her childhood memories still. It might be interesting if that was 'visible.' It was repression based in emotional trauma, yes, but I don't think those are coming back, so.
-Related, probably the mother issues count as something of a lingering scar, but one that will fade given time.
-I feel like I'm missing something, but this is probably enough to be getting on with? lmk if it's not.
