Tasara doesn't know what the Domain was thinking, sending this girl here. Either they're more desperate than she thought, or this girl is extremely foolhardy. Likely the latter. She's, hm, maybe three years out of training, judging by her stamina. Not much finesse, but exuberance in abundance, and a stubborn refusal to admit she's outmatched. If they were further from the city Tasara would flatten her, but the goal is defense, not destruction.
A thoroughly sedated civilian - someone unlikely to be able to fight off the intrusion, but with a compatible brain.
And, soon enough - Kushina is embodied again.
She blinks, stretches her hands, and hugs Tasara.
And things settle, a bit. Kushina re-acquires her son, tests out that her body has minimal complications, gets into several public rows with various councilors, throws herself into politics...
The Uchiha recover from the attack. Obito wakes up, on their side, ready to assist in finding their enemy - and relaying everything he knows about Madara's plots.
The girls are there to lead the charge, and systematically dismantle everything Madara has set up. They try to leave internal politics alone as much as possible, though the situations in Rain and Mist are enormous headaches.
Kushina is not leaving internal politics alone. Weeeeeee she gets to be Hokage! Your reforms suck Sarutobi, nyah. Luckily apparently shinobi appreciate her style of diplomacy, so even with Zetsu screwing around she's able to help build coalitions.
Obito's able to help out with Mist, at least - and has a lot less hesitance to interfere with other people's politics. Fortunately there's a handful of Mizukage candidates who've been able to keep their hands mostly clean (for shinobi values of 'clean'), and one of them, Terumi Mei, steps up.
Rain dissociates themselves from Zetsu when the world swings against them with the revelations about Madara's plots, and the nation retreats back into isolationism for the most part.
Zetsu vanishes, as far as anyone can tell.
They'll just have to keep an eye out.
Though when Cloud sends a retrieval team, Anneia will admit to getting a bit distracted. Her explanation to the Raikage why this was a bad idea was very calm and polite, she thinks. Considering the circumstances. She only broke one wall of his office, anyway.
He broke the other two, so.
But the villages were already in a period of isolationism, if not fully peace, so twitching them away from fighting each other (at least openly) isn't too hard, especially given an enemy they can blame for their troubles and claim to be acting against without actually expending many resources.
