'You're welcome.' It's now more notable that Yamanaka Inosaki is using a polite form, though in a way that indicates she's talking to a stranger not in her own hierarchy. 'Can you easily produce some examples of the written form of Basic?'

'Yes ma'am. Is there anything in particular you'd like me to write?'

'Something to showcase every phoneme, but separately these phrases would be useful at first pass...' She rattles off a collection of diplomatic phrases.

'Yes ma'am.' She does, in order, with duplicates given where the proper form varies by station or situation. She also explains Sith ranks, of which there are five - dark councilor, darth, lord, apprentice, and acolyte - and that any Sith outranks any non-Sith.

Inosaki is thankful, and returns the favor - there's three types of magic users: samurai, ninja, and monks. The main distinction is historical and political, though they fight differently. The samurai out-rank monks, monks outrank civilians, and the shinobi are outside the system (they answer to the daimyo, but they outrank nobody and nobody else outranks them), though this sometimes works out differently in reality.

The samurai rule the nations; there are the daimyo (the warlords and rulers) and below them a fluctuating number of ranks depending on each daimyo's whim, and mattering mostly to the courts. She can list the current ones for this particular nation (of which there are six, each subdivided into 'Senior' and 'Junior').

The ninja, like herself, have a more cobbled together system. The Hokage - Lord Hashirama - rules the village. The Hokage's second-in-command is the Commander, currently Lord Tobirama. The four ranks below the Commander are the elite, the middle ranks, the apprentices, and the Academy students. There's also the old system of organization, the clans, which is still a bit important. Clan heads lead their family. Ninja outrank civilians within the village, but not without.

The monks have three ranks - temple head, ordinary monk, and apprentice - and stay out of politics and wars.

'Thank you, ma'am. May I ask how these ranks are gained?'

'Among the ninja, students become apprentices when they show they've mastered basic skills across disciplines. Apprentices reach the middle ranks after an evaluation based on mission performance, usually including a teacher's recommendation. Middle ranks reach the elite ranks due to an evaluation of mission performance, an evaluation of skills in certain disciplines as being over a certain threshold, and usually having invented a technique, though that last requirement can be waived. This last promotion is considered more likely if you're willing to share invented techniques. Students usually come from the ninja clans, though civilians can apply as well; there's an entrance exam. The clan heads elected the Hokage, and he appointed the Commander.'

'Among the monks, usually seniority. Among the samurai, a combination of talent, birth, and political favors.'

'Thank you, ma'am.'

'You're welcome. How do the Sith reach promotion, or become Sith?'

'People with the potential to become Sith are very rare; one in ten to fifty billion among species that have them at all. Anyone found to have the potential is obligated to be trained, either at the facility on Korriban or by a higher-ranking Sith, meaning that some Sith skip the rank of acolyte altogether; the rank of apprentice is automatically granted on being accepted by a master. Higher ranks can be granted by a Sith's master or their master's master, or earned by killing a Sith of higher rank, in which case the victorious Sith inherits everything belonging to the defeated one, including their title, positions, and underlings.'

'Interesting. Your world must have many people.'

`I wouldn't know how to compare, ma'am.'

She nods. 'Is there anything else you'd like to know, while I have the connection maintained?'

'I'm all right for now, thank you ma'am.'

'Alright. I'll break the connection now.'

And she removes her hands, stepping back. "We should be good to go, language-wise," she informs the room.

"Yes, thank you ma'am."

"Good. Well done, Inosaki," says Tobirama. "Do you have any immediate needs, for yourself or your master?" he asks DZ. (He's not relying entirely on someone who's clearly a stranger to them both to have communicated everything accurately.)

"Nothing immediate, sir. Deskyl will need to eat in a few hours."

"We'll have soft foods available then. Is Deskyl likely to react poorly if others are in the room when she wakes?"

"I've never observed that in particular but I don't expect so, sir. It's a very gradual process; she's technically awake now, but the only thing she seems to be aware of at all is this girl's presence," she says, indicating Desuka.

"Reika and I will stay to continue learning Basic, then," he says - fortunately, they're in a small lull in paperwork and administrative duties, so he can afford time off. Though there's still some things he should work on while he waits... 

Then, to Ryousei: "If you're planning to stay, Inosaki can retrieve anything you need and inform your family where you are, but you're not required to remain."

"I'm staying with my friend."

"Very well." Then, to Desuka: "Do you want anything other than food and water?" He's assuming she wants to stay.

She pats Deskyl's hand and shakes her head.

He gets food, water, and ways for the children to entertain themselves set up, then dismisses Inosaki. 

Over the next few hours he splits his attention between where Reika is learning Basic from DZ (occasionally asking questions of his own) and some non-classified paperwork he pulls out of his storage seal. About an hour in, Ryousei gets bored with her book and her wariness and starts on-and-off quietly asking Tobirama questions about Academy-level magic and science whenever there seems to be a lull. He answers her questions with apparently unwavering patience, and encourages her to write down any questions about the other universe she has for DZ, so she can wait to ask them.

Reika learns anything she sees in an instant, and is slower on verbal learning but not by much, so Basic lessons are likely to progress quickly.
