"These two first, then. The rest of us can continue."

"Alright." She lets her grandfather know. "I'll take one at a time; it's a bit better that way." She glances at her sensei. "Do you want me to come back here after?"

Kakashi flicks his eyes over Jakuan and Occlus. "If you're not too worn out."

"I don't think I will be."

"Then I'll be in your care, Tobi-chan."

Grin. "Be right back."

Then: zoom! She isn't immediate on each return - she needs to talk to the border guards and do hand-offs - but she definitely gets back quickly.

...It is also plausible to the Force-sensitives that she could modify this technique only a little to enter hyperspace with it. She seems to be technically crossing the distance in between, but - in some ways she isn't, really. She is definitely not leaving the sonic booms she should be, and neither passenger feel like they just moved.

Hm. Impressive.

As long as they're running back... Does Occlus object to quizzing on engineering?

Not so long as her interlocutor does not mind that she is not an expert in the field. (Still fairly knowledgeable, though.)

A non-expert overview is a good place to start. (Tobi: has a perfect memory, can extremely rapidly assimilate and apply new information, and can do improbably complicated math in her head - she does in fact start musing about using seals to augment or replace physically engineered elements of a vehicle, and the parts she mutters out loud sound like they're based in principles that'd be impossible for most people made of cells to hold in their heads at one time.)

"You think quickly."

"A bit faster with my sharingan active," she gestures at her red eyes. "But in general - yeah, all shinobi do, and I'm faster than most."

"A useful talent to have."

"It's convenient for sealing."

"What does that involve?"

"The most basic methods involve externalizing the paths chakra would travel in your body, to create a preformed technique you can activate later. Though the most common are using that to create a container - a stable anchored technique can do things an actively formed technique can't, and the most basic form of that is energy storage - creating stable ways to slowly remove a storage seal's contents is extremely hard, though, so you mostly find that in explosive tags..."

She rambles on for quite a bit. It turns out each sealing tradition or style calls on very different skills, and Tobi knows several, but 'think on your feet,' 'good at math,' and 'eidectic memory' are common requirements.

Seems a fair trade for galactic engineering as they travel.

She fully agrees.

Excellent.

And sooner or later, they'll arrive.

There's someone waiting with the gate guards (and Ani and baby Anakin) to meet them. He's pale - albino, likely - and wears a different style of armor than most other shinobi they can see, and he doesn't have any discernible marks of office, but... He carries himself with an air of authority.

Also, he looks and feels similar enough to the three Uchiha, and something deep in him brightens a bit in fondness when he sees Tobi.

"Welcome to Konoha, visitors," he calls out.

"We thank you for the welcome."

He inclines his head. "I am Senju Tobirama, Second Hokage of Konoha."

"Who are you?"

"I am Occlus, This is my wife Ani and our grandson Anakin. It was he who encountered your Tobirama during the brief while she was was dead."

He regards them for a moment, then half turns. "Follow me."

Into the city.
