Margaret is on her way to work at the CDC, walking instead of flying today so she can drink her coffee without spilling it, when she sees the cryptid. She's a truly far-out one, no limbs to speak of, just a long snaky body with a mirror for a face. Margaret smiles at her and goes to walk on by, but the cryptid slithers right at her all of a sudden and--hits?--Margaret with the giant mirror. Except she doesn't experience getting whacked with a sheet of glass.
"I wasn't expecting her to really find a legendary!"
"I think I am not what she was looking for but I am . . . very strange. And from very very far away."
"Close enough," says Bella.
Renée goes to put in a delivery order.
"Can you tell me more about legendaries?"
"Legendaries are... Pokémon there is only one of."
She's not sure how to ask "like mutants, or like the last of a nearly extinct species" except by saying "Because they're the first one like them, or because they're the last one and the others are gone?"
"...first," says Bella, "but they... stay first, they don't make more. And might not be real - people don't see them much."
"Oh. If they are real, where do they come from? Or do people not know?"
"They might not be real. But if they are real - they don't die."
"Oooh. And you think humans could learn how to not die too?"
"That's why I look. But they might not be real and you are real and interesting, so I'm going to stop looking and figure you out first."
"Okay. I can't share what I can do, or explain all of how it works, but I can talk about it."
"Maybe that's enough to get somewhere!"
Margaret nods, and starts explaining magical girls, with occasional pauses to look up or solicit a word.
Bella takes notes and tries to help with the language till dinner arrives. Dinner is dumplings full of veggies and tofu, and rice, and seaweed salad.
Magical girls: they're always girls, somewhere between six and sixteen. They get this visual thing and the ability to change their bodies. If they make enough changes, they get magic and the ability to change their clothes. Margaret's magic does what it does; other girls she knows of do this that and the other thing. The more you conform to a certain aesthetic the better your magic gets. Swarms are a thing and this is what they are like.
Dinner is delicious and she is appreciative, though the seaweed salad takes a bit of getting used to.
"Who gets to be one?"
It's more likely if you have relatives who are magic, but it's possible for any girl and guaranteed for none of them.
"Can you make it more likely with... blood transfusions?" She explains those.
"Hmmm. . . that doesn't work on Earth, but maybe here it would take someone from impossible to possible?"
"It's been tried on Earth?"
"Yes but I don't know the, what's the word, details." It's good that she's a biology major and not an economist or a city council member or something, but if she had known this was going to happen she would have studied magical girl biology in particular a lot more.
Bella nods. "- do you sleep?"
"Yes, the same as other people. Maybe eight hours a night."
"Couch okay?" Bella pats the couch.
