For best results? It'd probably be dropping him in like MID- attack on Uzushio? So most of the ninja there are def alive but the village infrastructure is fuuuuuucked. More rubble the buildings at this point.
So like? One moment: it's Uzushio's last stand. Civilians cowering in the bunkers. All hands on deck. Even GENIN, fresh from the fuckin ACADEMY at desperately trying to hold the line. The Uzukage himself? Bleeding out Chakra to hold the final emergency barrier like a fatal wound.
When?? The FUCKIN OCEAN rises up to attack in invaders.
No a water jutsu. Oh no! The OCEAN. As in, like, fucking ALL OF IT. A metric FUCK TON of unstoppable, unkillable, and utterly endless watery DEATH. That ocean! And there? Looking pissed? Is just... some dude!
....we like some dude! In fact? We here at Uzushio LOVE our new best friend Some Dude! He's invited to the wedding and every family gathering we'll ever have! Some Dude for president Kage!
Those still left alive? Salute you! But like... also our Kage is NOT gonna recover from his glorious last stand. He's fucked. We're fucked! We thought we could count on Konoha, but they NEVER FUCKIN SHOWED UP! So like? *slowly put the hat on our new beloved friend Some Dude* no take backs. We're YOUR problem now. *uzu-nin has used Audacity! It's super effective!*
And like? Shit, man. If the new kage says we're a "camp" now? Guess we're a camp! We'll call it what ever you want, ocean god! Just keep telling the other villages to fuck off! We'll work around ya! Seal the new place to hell and back! Fuck it. We're all in on this "let kids be kids" thing! Sounds nice, honestly.
