Well, it's precise enough to do something. A person pops into existence - "pops" isn't really the word; there's no accompanying sound - in the middle of the seal. "Person" might or might not be the word; he's foregoing a shirt to accommodate a set of blue batwings and his pants are slung a little low to accommodate a blue barbed tail. "Hullo there! You're letting me talk, I appreciate that in a summoner, what can I do for you?" He glances around at the surroundings.

His summoner appears to be in that vague early- to mid-teens age range, probably between fourteen and fifteen. The room is windowless stone, the door wooden, the air still and heavy despite its large size. It's lit evenly by lights on the walls near the ceilings. There's a single new language, similar enough to Japanese that a non-speaker would probably get them mixed up.

His summoner also has bright red eyes, which are currently narrowed suspiciously at the new person. (Orochimaru could've told him this was a probably untested summons-seal, but that would require basic safety standards, wouldn't it.)

"I'm not used to humanoid summons," he says, evenly. "Which realm are you from?"

"...run that by me again? You're not used to humanoids? Do you typically summon angels off a body mod club membership roster or something? - is this Venusian Japanese?"

"I don't know what an angel is, or what Venusian is. I'm speaking the main language in the Elemental Nations. Most summons are nin-animals from different realms; if you're usually summoned to another continent I guess it could be different there. Where are you from?"

(Nin seems to mean "person" and implies "magic".)

He rubs at his face. Orochimaru is probably going to want information, too, not just 'hey yeah your seal worked'...

"I'm from a place called Hell and I'm really confused."

"About what?"

"Who hasn't heard of angels or Venus? What are the Elemental Nations? Where are you getting sapient summonable animals from? Given that all of this is not as expected how did you summon a demon anyway?"

"I haven't. They're a cultural group - Lands of Fire, Earth, Wind, Water, and Lightning. From summons realms. My teacher gave me a seal and told me to draw it."

He shrugs. "I guess my teacher wants me to get information. I can summon a snake, if you want to know about local summons."

And then maybe he can summon one of the talkative snakes and not deal with surprise interview.

"...sure, if you don't mind summoning a snake for me."

He folds his hands into a few odd shapes - not a language - and then kneels to tap the floor.

And, in a puff of smoke, a large snake mottled brown and white appears. There doesn't seem to be a summoning circle.

"Summoner!" she says, immediately coiling around the boy's feet. "I want noodles."

He sighs. "You can have noodles later. I wanted you to talk to - someone from Hell that Orochimaru had me summon."

She climbs up Sasuke, looking at Cam over his shoulder. "Lord Orochimaru has odd taste," she comments. "Is Hell a new summons realm? What's your name? I'm Shiromi, the rude one is Sasuke."

"I'm Cam. Is, uh, limiting snake access to noodles important for some reason?" Cam asks Sasuske.

"No," they say at the same time. Sasuke's tone is more long-suffering, while Shiromi sounds more energetic.

Cam presents the snake with a bowl of spaghetti. "Do you want sauce? I assume you don't want a fork."

"I don't need sauce. Where'd you get that from?" the snake asks.

"I made it. Help yourself."

The snake hums, then figures she's very hard to poison as a nin-snake and also can just dismiss home if she feels poorly, and then slithers into the bowl. Actually eating the noodles seems to be a mild challenge for her.

Sasuke sighs. Well, there goes his plan of 'make the snake do all the talking.' "How did you make it?" His sharingan is still active, and he didn't see any movement of chakra...

"That's what demons do, we make things. Do you have such conveniently summarized abilities yourself, I'm still a bit lost."

"I shape chakra into patterns, and it does stuff depending on the pattern. Chakra is the energy in everyone and everything. There's fields of focus, but they're not as broad as 'make things' - can you make people? Is there a mass or density limit?"

"I can make human bodies but not conscious ones, the intellects of things I make tops out around 'bug'. There are limits to volume per time but I think mass factors in at all, I can look up the current best understanding of the operative formula if you're curious but the upshot is it would take a few weeks to make a planet."

He makes a very complicated expression. Then, to the snake: "We're not telling Orochimaru."

The snake pauses in eating. "Should I dismiss, I feel like this is a 'no potential leaks' conversation - "

Sasuke sighs. "Go ahead. Tell Aoda I might be in trouble soon."

"Right! I heard nothing." And the snake vanishes, alongside the noodle bowl, in a puff of smoke.

Sasuke takes a deep breath and sets in to gather his thoughts.

"...I mean, that doesn't mean that I can be convinced to make a planet if someone wants a planet for bad reasons."

"There are a lot of things that aren't planets someone could cause trouble with, and I assume you're not the only person from your summons realm."

"I am not. What are we worrying about here?"

"First, if he doesn't need farmers to feed his troops he might decide they're all experiment fodder. Second, he can use living sacrifices to resurrect immortal, indestructible soldiers under his sole command. And if he has any other source of my bloodline power he might just kill me. Unlimited food, resurrecting the dead, and spreading bloodlines aren't bad,  he's just specifically an ass."

He's talking faster than he usually does, a bit agitated.

"You work for this guy why?"
