Itachi does.

He starts to dissolve, too, alongside the others, all controls on him broken, and turns to look at Tentou.

"I'm sorry for hurting you - your alt, I suppose. I was a fool. In a way... Love isn't enough, is it, to stop us from hurting each other? Especially when we think we know better."

"I had no right to do what I did to her."

"Hopefully, her future will be better."

And he's gone.

Madara does not dissolve.

"How touching. My clan is rather plagued with sentimental fools, it seems."

"We'll have to banish this one specially, it seems."

"You can certainly try."

His Susano forms around him.

"Your younger reincarnation displayed more grace in his fate."

"This Itachi being Madara's reincarnation explains quite a lot, actually."

She teleports behind him, within his Susano -

And rips his soul out through his spine.

He crumbles.

"Don't think he was expecting that."

"He really should've been!"

"Well, his inattention is our gain."

She nods. "I think the next order of business is the rest of the Akatsuki - they should be rather simple, though, all things considered."

"An advantage to taking the hardest targets first. It's all downhill from here."

She laughs.

"Do we want to bother splitting up, now? No one should actually have major surprises - Pein has my powerset, spread over more bodies, but if you take out the central body you won't have trouble, and the only annoying one is the soul-stealer."

"As long as you're in the group that takes Pein, that should be fine."

"I'll focus on him then the tailed beast statue. Tobirama can help track the other Akatsuki members; he has ever seen them, I think."

"That seems like the limiting factor in splitting up."

She laughs. "I know how to find some of my old friends from my world - at least one of them was as good a tracker as Tobirama. So we could do as many as three groups, there."

"That first, then."

She consults with Tobirama - identifying the person of interest as 'the female Uzumaki, should be near a Hozuki and someone with unstable chakra,' and opens the portal herself, stepping through.

The Keres follows after her.

"Where'd you take Hisame?" the woman on the other side asks immediately - she seems to have been ready for them, flanked by two men - one, slim, with white hair and a massive sword, and the other enormous, with orange hair and a deep frown.

"It's good to see you too, Karin. I'm an alternate universe Hisame. We fixed the mind control on her, and she's recovering in another world, well away from all this. And, yes, that did require killing her - which I am sorry about."

The two men trade looks, while Karin frowns. "We'll want to see her - but for now, you've been picking fights here. What do you want from us?"

"We're taking down major threats to this world. Kabuto was ready to set an army of Edo Tensei against the world. The shadow was planning worse. We'd like your help with tracking down the Akatsuki's remaining members."

"As long as I get Kisame's sword, I'm good," the white haired man says, grinning.

Karin flicks her gaze at him, frowning deeper. "Alright. We're in," she says.

"Excellent! One of my alts controls Madness, by the way - she should be able to help Juugo with his rages. Probably best if after that we drop Suigetsu and Juugo on you guys' Hisame - we'll be moving fast against the Akatsuki, you understand."
