Something that came up on discord earlier today: skytowers still seem to be a Leaf-exclusive secret, and as a result nobody else should have the ability to travel far out into sea without a boat. Ninja can island-hop by running across the water, but only when they can make the trip in one go. Boats, meanwhile, suffer from the constant worry of hostile aquatic chakra beasts. You can't disengage from combat as easily as you could if you had skywalkers equipped, and if you lose the ship you better
hope you're still within range of the shore.
This all to say, the deep sea honestly sounds like a pretty safe place to be. Nobody knows that Leaf (and by extension, us) has the means to run that far out without relying on boats, which means they shouldn't expect us to be out there in the first place. It seems likely to me that the Akatsuki has sufficient hax to also traverse the deep sea (even though I can't think of anything off the top of my head), but they're much less likely to head out in a direction they believe we most likely can't physically be in.
The question, in this scenario, becomes "so how do we do our research?" Doing it on top of active seal effects is forbidden, of course. One option is to find a small island like a cay/key, way out in the deeps. But I'm not sure we could find one, or that it'd truly be as secure as we'd like, so I have two rune proposals that might give us some land to work with (one my own, one provided by Buggy):
- A rune that raises a pillar out of the seafloor, like MEW writ large, creating a small island just large enough to build a research facility on.
- A rune that freezes a large amount of seawater, forming an iceberg large enough to build a research facility on.
The first one has raised concerns about affecting the ocean currents. I'm no expert in such matters, but I think that if we're just raising a pillar and the pillar isn't too large in radius then the effects might be mostly minimal? For the iceberg, the worry is more a question of how stable it'll be: if it's bobbing and turning with the waves, I doubt the facility we build on it would be up to spec.
Both of these warrant prep days, I think. The requirement that research facilities not be built on active chakra effects is our biggest limitation on where we can go to avoid pursuit, and it would be very convenient if we could create temporary islands to alleviate that problem. We can still look for keys if they both fail, but I'm broadly feeling good about this line of inquiry. And the fact that we by right shouldn't be able to go this far out into the ocean is a very promising avenue to follow for evading pursuit: I once argued that one of Hidan's main limits is the point where he's followed his Jashin compass far enough that the hypothesis "I missed Hazou and am just wasting my time going further" outweighs "Hazou is still somewhere beyond this point". I mean, I don't
actually expect Hidan would reach the edge of the EN, past which there's boundless ocean, and figure we must be
yet farther than that, as opposed to his trajectory having just barely missed us somewhere along the line.
If we're so far out that nobody credibly believes we went that far (because they do not know that we're capable of doing so), we win the hunting game. Or at least, our odds are much greater, even against Hidan and his Jashin luck. I'm thinking this is within our means to achieve, especially if one of the two runes I outlined works out, and is a strong contender as a main hiding strategy.
