'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.

DZ can go as fast as Reika likes; she does start out with an assumption of normal human learning capacity but very quickly picks up on the difference and switches over to teaching her the same way she'd teach another droid. She starts with the most basic necessities to get by - yes and no, simple question and answer words, pronouns, and the like, and then methodically works through the most common hundred, five hundred, and thousand words in the language, interspersed with grammar lessons as examples of different parts of speech come up.

That done - and it takes a couple hours - she stops to ask what they'd like her to focus on next. "I might need to skip the section about starships and space travel, though. It translates very poorly, and I don't understand the topic well enough to explain the terms in depth."

"Those don't seem to be concepts we have yet, yes," Reika says. 

"Now that we know it's possible we might look into turning research to it, but I imagine if we do invent space travel at that point it'll be easy enough to re-exchange vocabulary with whoever we meet. Though I suspect something relying on chakra, especially seals, will be easier for us," Tobirama comments. "Summoning techniques exist; I'll have to devise a test for if they work faster-than-light."

"Yes sir. Deskyl might be able to help with that; it's not her specialty, but she is an engineer, and fairly well-read."

He nods. "My specialty is seals and inscribed techniques. Those cover anything we'd use of our own magic."

Modifying his Flying Thunder God technique to work across massive distances, so that one object would be moved to a specific seal, is a consideration, as is moving in and out of summoning realms, or a seal that pulls specific objects to it... Of course, he's unlikely to crack immortality in his lifetime, and his brother keeps shooting down his research into necromancy, so it'll probably be something to leave to a successor to finish, but he can start. And even small steps forward will benefit the village.

"Yes sir."
