Reasonable.

Most of the rest of his questions are on minutiae about this or that detail, though once he runs out of pre-prepared questions he gets tired quickly.

Jiraiya wraps up his work quickly.

"Thanks," Sugira says when Jiraiya seems done.

"You're welcome. Try to avoid chakra exhaustion, I can't promise that the ward will hold absolutely, but other than that, you should be fine."

Nod. "I'll be careful." Especially during training with the chidori; it'd be monumentally stupid even for him to run himself down that far outside of a life-or-death.

Jiraiya nods and claps him genially on the shoulder (the other one), then moves off to see if Naruto is free.

The original can peel off while the clones keep working.

"Hey! Did you get Sasuke's thing done?"

"I did indeed. That's an impressive number of shadow clones you've made here."

"Thanks for helping him! And yeah, I have a lot of chakra."

"Indeed, indeed. Have you ever wondered why?"

"Combination of being an Uzumaki and interactions with the Nine Tails - I'm not pulling directly on that chakra usually but it's probably doing something to my reserves, y'know? Just sitting there."

Sasuke is a history nerd in addition to all of his other nerderies and has found a surprising amount of information on the Uzumaki clan. Which is still almost nothing, but, well, Naruto clings to it.

"Seems you already know everything there is to know! You must be feeling confident for the last stage of the chunin exams."

"I mean, I've got a plan I'm pretty sure'll work against Neji, and we're gonna work on backup plans once I get this technique down, and with Chihiro I just have to worry about making sure we both show off the right kind of stuff and all, and we're planning on Chihiro winning me and her's fight."

"So I guess you don't need a super A-rank technique of your own, even if Hatake is teaching Sasuke one."

"I mean if it's something that's time limited to learn, or will help against Neji? But in fine waiting my turn for the stronger stuff? And if it won't really help against Neji then I need to focus on stuff that will? ...Why are you offering, anyways?"

Random people usually don't offer to teach him, after all, and Jiraiya is really hard for Naruto to read despite his apparent exuberance.

"I'm the only person alive who knows this jutsu. It takes a special kind of chakra."

"So you wanna pass it on, and I fit the bill? What is it?"

What Jiraiya said doesn't feel entirely accurate, though. Like, there's no tells Naruto can put a finger on, but...

Jiraiya holds out his hand, and concentrates for a moment. A swirling sphere of chakra forms above his palm, dense enough to be visible.

"It's called Rasengan."

Focused squint. "So - guessing close-range, probably does a lotta damage to a small area?"

Probably not the most useful against Neji...

"Watch this." Jiraiya steps over to a tree and presses the Rasengan against it. There's a noise like a very focused woodchipper, which stops when he pulls his hand away and lets the jutsu fade. This side of the tree now has a neat circular hole in it, letting them see all the way through.

"Cool! - Probably shouldn't try hitting an ally directly with it even if he is an ass... And I'm trying not to get in tapping range of Neji..." He seems distracted briefly, then: "Uh - you're not usually in Konoha, right? So I'm guessing offer's not like always open?"

"No, I'm not," Jiraiya says. "But be sure to check the other side of the tree too."

He circles around. "I can put me and a couple of clones on learning it I think..."

The other side of the tree looks... exploded. Bark is shredded and wood is splintered outwards from the hole in a conical pattern.

Huh yeah not using that on anyone he doesn't want dead.

"Cool, how's it do the explode-y thing..."
