Masaru turned his head towards Yukine and, after acknowledging the fact that everything that was usable in the shipwreck had [i]probably[/i] been pulled out by now, nodded to the kitsune as he moved to double-check the crate. Even if it had been already checked over, it didn't hurt to at least make sure of that fact. And, well... To be fair, the sooner they got the whole 'not starving and/or dying of thirst' thing out of the way, the better.

"Uh... Right. Well, uh... Yeah, I guess that's kind of a problem. We should probably get some place that's a bit farther inland, though...? If the storm that dropped us here is anything to go by, then without any sturdy shelter staying in here might only help us kick the bucket faster," he thought, glancing at the sea and grimacing before shaking his head. "Yeah. Maybe a bit further inland in better for now. It'll do until we can get our bearings straight and not have to worry about day-to-day survival and all that."

Turning his attention back over to the crate, Masaru took a deep breath and...
Casually popped open the top with minimal effort. Huh. Seemed the crate wasn't as sturdy as he'd expected. Or maybe he was a bit too strong. Whatever.

With that cover now flipping in the air, the oni casually glanced into the box and attempted to pick up a piece of the hardtack. Seeing that it was still in one piece (and, surprisingly enough, not as wet as he had expected it to be), he casually placed it back in the crate.

"Okay!" he called out, lifting the crate up before turning to everyone else who could be listening in. "Everyone who can move something, pick up whatever's left and help bring it to some more stable land! The sand here's not going to be growing anything any time soon, and it's probably not gonna be solid enough to get any sorta foundation up! Once we move a bit deeper, let's try setting up a shelter to keep this stuff from going bad from exposure! That okay with everyone?"

After that half-request half-order, Masaru turned to Yukine to check if his perceptions about farming (at the very least) were true. As far as he knew, sand was horrible for growing crops in, so... Yeah.
Also, the frustration of being tossed out to sea like this made him want to punch things really badly. Punching down a tree or five?
...
Yeah, he could do with that.
