"Okay..."

Hashirama relaxes, settles in to focus on healing himself.

(He's going to be exhausted after this, but, well, Sasuke doesn't seem to have any kind of grudge against him, and if the Uchiha and Senju really are allies in his time...)

...Something about that face is annoying Sasuke. It's a very inconvenient face.

He huffs, turns away, and stalks off to go harvest seaweed and other assorted vegetation.

Hashirama keeps healing himself, and drifts into sleep before Sasuke finishes.

The sunset on this planet, when it comes, is long and brilliantly hued, the air far above wavering. 

The dying light doesn't reveal anything as pedestrian as stars, though, and as the sun grows close enough to obscured to be looked at it becomes apparent something is very, very odd.

For one, it's not a single mass - it's many shifting bits of glowing light, moving together so tightly they resemble a sphere.

For another, strange creatures cross the sky amidst ribbons of blue and green light that scintillate across the cosmos, and the closest things to stars are distant moving glows - Sasuke's sharingan will be able to detect even the apparently stationary stars moving in an unexpected pattern.

This definitely isn't his home world.

He'll force himself to stay awake while Hashirama sleeps, through the burst of the glowing sun-pieces back over the horizon. He has some food sealed away; he doesn't want to risk going out hunting while the only medic in the area is unconscious and vulnerable, and he hasn't recovered enough for shadow clones. So, he unseals a few simple things, collects water, and has a broth ready for Hashirama when he wakes.

Which he'll do a few hours later, initially coming to groggily then snapping the rest of the way awake when the weird registers to his chakra-sense.

"Hey. You awake?" Sasuke asks from a hopefully safe distance in case Hashirama has any amnesia.

He groans, and remembers getting dropped on the weird world, meeting Sasuke, getting punched by a shrimp...

"Physically? Yeah. Dignity may never recover."

A snort escapes him, almost surprising him. "Like you had any in the first place."

"Take that back! I'm made of dignity!"

"Made of dumbass, maybe."

"So mean..." Hashirama says, curling in on himself and sulking.

...What is that weird feeling in his chest, it should stop.

Sasuke looks away, crossing his arms and not pouting.

Hashirama's not going to stop dramatically pouting on his own, unfortunately.

Argh.

"Come on, idiot, you need water and food," Sasuke says, huffing. "Or I'll dunk you in the stream."

"You're worse than even Madara..." Hashirama mopes, but unfolds and obligingly eats Sasuke's rations.

"We should be more careful, I guess, when exploring now. Move together, don't split up."

"As the medic, you especially need to be careful," Sasuke acknowledges. "I'm probably faster than you, with better reactions, so I should be taking point."

"Don't really like that, but you have a good point..." He shrugs, finishes up his meal. "Explore out in a spiral?"

Sasuke nods. "I can show you what I've found, too..."

There's a stream nearby them, deep and crystal clear, with translucent winged fish flitting through it. There's the coral hills, which in the morning's light have numerous colorful creatures flying about - they have a shape reminiscent of birds, but scales like fish and wings like a butterfly or dragonfly. A few creatures lie in wait for prey in the coral, visible easily to Sasuke's sharp eyes but Hashirama will have trouble spotting them all, so cleverly are they camouflaged. 

The seaweed forest is tall and dense, and the light barely penetrates into it. Nothing's attacked Sasuke while he's harvested from its edges, but he's yet to go too deep in.

Once they make their cautious way near the top of a taller coral hill, the gentle rise of a volcano becomes apparent in the distance. It doesn't seem likely to be imminently in danger of erupting, but, well, neither Sasuke nor Hashirama are exactly volcanologists.

The soil most places is a thick, ever-shifting sand, too heavy to be picked up by the wind easily but inconvenient and slippery like mud.

There's a distant noise, growing and fading and growing again, a wailing song. Whatever it is causing it isn't visible nor able to be sensed.

"It's pretty, at least," Hashirama says, bending to investigate some more of the plants. "And at least I can tell which of these are edible... I'm not sure we want to risk any of the animals, though, I don't have as good a read on those."

Sasuke nods, and, wearily, "We'll probably have to find civilization, to ask them."

"I don't see or hear signs of anyone near, and this is a pretty fertile area, but they might just be at low densities." Hashirama shrugs and stands, twisting to look about.

"Inconvenient." He shakes his head. "We might be able to see more, from that peak," he says, pointing at the volcano in the distance. It's the tallest thing around, though not by much. "Especially if we jump." He's never used that to navigate, but shinobi can easily get pretty high in the air.

"Sensible. Let's secure some supplies first, though - maybe make baskets?"
