The jet passes, apparently serenely, through the formerly-empty sky above.
"Huh," says Marisa, who has been lying on her back staring up at the sky. "That's a new one. Are we finally getting a dragon?"
"Huh, okay."
She stands up, which doesn't get her particularly further off the ground than she was while lying down. She hops on her broomstick and hovers, which is significantly more effective.
"I'll go say hi, I guess. Do you think there's a lot of passengers?" Isn't it irresponsible to let a vehicle full of passengers in here? is the subtext.
Huh, this thing has "Southwest Airlines" painted on it. They seem pretty lost! This is definitely the East, even if it's not really east of anything!
Then again, it's probably just the airplane's name. Maybe it was built southwest of something.
It's probably piloted from the front, so the pilots can see where they're going. Marisa flies around to the front and waves into that window. (She's considerate, and doesn't go right in the center. Not much up here, and they demonstrably can't even shoot down atmospheric fairies, but blocking someone's view isn't friendly.)
"I'm going to want some more of that oxygen, actually," says one of the pilots.
"No, I think I see it too," says the other.
"You say it first."
The captain sighs. "There's a witch on a broom waving at us."
"Well, now I'm mentally primed to see that, since you mentioned it. But yeah, witch on a broom."
"HELLO!" shouts Marisa. (In English, because the writing on the plane was in English.)
Then she does some complicated magical manipulations, with a bit of a minor light show, and says it again.
(This is a considered strategy; it makes it obvious to the occupants, who are looking at her, that she's throwing her voice with magic. It's a nice flourish that it doesn't look all that considered.)
"There's no such area of sky, but I'll keep escorting you for as long as you need. Some friends of mine should be up here shortly, too."
Marisa hasn't really picked up the word "airport" from reading, but she gets the idea from context clues. "There's no airports nearby. You won't be able to reach one from here, either."
"Yes, that's what I mean, more or less. Don't worry, you're being escorted by the finest, and I can recommend a flight path to you, too."
Visibility is good, fortunately, so this is fairly simple. She'd cast some visual aids, but that's actually tough through glass; fixing that problem might be worth some research later.
"That mountain to your right is a dangerous area, but let me use it as a point of reference. We're south-southeast of it. If you look to its south, about three compass points clockwise from your current heading, there's a town; the gondola between the town and the mountain might be hard to see but it's almost perfectly north-south. If you're not going to fall out of the sky and crash anytime soon, I recommend circling over the town as tightly as you can; my friends and I will vastly outmatch anything hostile in the sky. If you are going to fall out of the sky soon, let me know."
Sanae drifts into Marisa's general vicinity. This plane is going really fast, which is normal, she supposes, but it's hard to keep up with. Mortifyingly, she's performing a minor miracle right now, though no one must ever know.
"The Mountain's airspace is at the disposal of our guests," she says.
Sanae isn't conferenced in, but the pilots of this airplane also likely don't speak Japanese. Marisa casts the extra spell anyway.
"My green friend here says the mountain's cleared you to fly over. Don't change your flight path about it, but it's less danger for you, so it's good!"
It's not good; the subtext is that the Mountain is interested. But that's a problem for future Marisa when she's getting drunk with these pilots, not present Marisa.
"I hope that's taken care of. What do you need to land? If you could just set down in a field you probably would have, right?"
"This aircraft is very heavy, and landing is still at a fairly high speed. Barring a real runway, we need a large flat area without obstructions. Landing on a large body of water is also possible as a last resort."
There aren't really any suitable large, flat fields, this area is all more or less mountainland and doesn't seem to have large farm fields anywhere. (Not a single sign of paved roads, of course.) If they really have to stay around here or get shot at, that lake isn't huge but might be the best option.
Sanae can barely follow this conversation at all, which is mortifying. But if she uses a miracle for translation, Marisa will know.
She can't even pretend to be distracted by sweeping the flight path for fairies, because Reimu is just doing that without any apparent effort. Or actual effort.
Curiosity tips the balance, and helps her enter the right mindset. After all, for a god, there are no "foreign languages".
"I can see why you'd have trouble! Don't worry, we can help."
Any one of the three of them are in principle capable of gently setting this airplane down in a field. That doesn't make it a good idea to rely on one of them to do it.
Marisa knows how to move objects around with magic. It's not really one of her specialties, though, and she isn't well practiced. And the known tolerances on her developed spells in that area definitely don't include something this heavy or moving this fast. She's reluctant to use something untested if she can instead find a more reliable way.
Sanae could probably perform a miracle, but similar considerations apply; she doesn't actually perform major miracles often, and they don't necessarily go quite how they're expected to.
Reimu, of course, doesn't actually inhabit the logical universe. If Reimu happens to drift over and nonchalantly say "okay, let's lead it to the ground now," Marisa will go along with this; it'll work. But you can't make plans involving Reimu.
"I'm going to ask some acquaintances for help. If they come through, we can enlarge a field for you. I think we can give you more than enough room. I'm not sure we can get you a paved road, I've never seen one but I know what they are. I'm going to make a call about that, though."
"I'll work as fast as I can. Sanae, can you go to the Mountain and ask about paving?"
If anyone in Gensokyo can pave them a strip to be enlarged, they're in the Mountain. Sanae's already as much as said she's representing the Mountain here, and she might as well make herself useful because of it. If someone thinks they're owed a favor, Marisa can deal with it later; more likely, the Mountain will be spending more than Marisa will.
Not as important, but still relevant, is that she's seen paved roads before and Marisa has not.
"You know, I really should, but I don't. I have some junk on me that might work, but I don't think it's worth you opening a door. Unless you do that all the time."
Marisa can actually call people, but not humans (they mostly aren't magic enough), and it's a really rough work in progress. She usually just drops in on people.
"See you soon!" And she flies north.
Sanae doesn't keep abreast of the local technology level, that's not her job. It's not that implausible that they can pave a (miniature) airfield. And if Marisa thinks she can get a miniature airfield enlarged, she's right.
The problem is, it's not that implausible. This is all above her pay grade, but she thinks the idea is that fake pseudoscience technology is a lot easier to research and develop here than boring real technology.
Which is why they have a fusion reactor, but she can't charge her phone.
I'm setting it up for you.
Kanako has formed a body to negotiate in person; tall, wide, and mountainous. She's not particularly lowballing the kappa engineers. This whole situation counts as a capital expenditure, and she's not a quarterly-report-chasing sort of god.
Besides herself, Marisa can think of two good space-expanders off the top of her head, though she's sure she could scrounge up more if she has to.
Sakuya is a hobbyist, but Marisa knows she's good at it. They've got a longstanding relationship, but she'll want to be paid.
Komachi is a professional, but she's a slacker. That's fine; Marisa can finesse her.
It's unclear how compatible what they each do would be together, but Marisa thinks she can stabilize whatever mess results. She couldn't do it at all on her own, it's not an active research area for her, but she has a rough intuition built for it.
She flies to the Sanzu-no-kawa, the river separating life and death, which is north of the mountain, because she has to get Komachi physically but can send a message to Sakuya (a target she's practiced her rough message spell on already). As she flies, she composes that message.
Got an emergency! ☆⌒(> _ <)
