He flares a piece of Susano'o between them, a single ethereal bone, to buy him enough time to fling himself out of her way - and he creates a shield of fire between himself and Jakkou -

She takes advantage anyways, flash rifts tearing through the fabric of reality to make a path -

For her to retreat. She hates melee.

Crows of fire pour out from under her cloak, winging for both her siblings - mostly Jakuan - and they explode into sharpnel when disrupted -

Tobi twists - and uses Hiraishin again, flitting between the crows to disrupt enough these won't kill Jakuan, filling the space between the twins with fiery death, and then reorienting and zipping for Jakkou.

Her little sister is very, very annoying.

Jakkou gestures, ripping enormous rifts around Tobi, blindingly bright and deep enough to cut through the edges of their universe, distorting time and space and disrupting the flow of chakra around them.

The rifts start to close on their own, of course, but not nearly as fast as her normal ones.

Hiraishin is a time-space ninjutsu, so - yeah, that fucks with it. But unlike her siblings, Tobi can feed data from her sensory powers through her sharingan and predict more than just the flux and flow of yang chakra.

Getting out of here without getting torn apart should still be nearly impossible.  Jakkou's gotten a pretty good measure of her Hiraishin, apparently. But Tobi's a seal master, and -

She's known Jakkou can open rifts for a while.

Dimensional stabilization seals flare at her fingertips, slashing at the rifts' edges, tracing along the exactly correct threads, weaving a path as her Hiraishin flares throughout her body -

She hadn't known Jakkou could cut all the way through the edge of the universe. She's compensating a little -

She realizes she's not compensating enough, not for what's on the other side, an entire two seconds before the rifts twist and try to close in a chaotic scramble, several inverting -

It's enough warning to make that scramble non-fatal. It's not enough to stop it.

One of the inverted rifts spits out a man -

A very, very familiar one. He lands on his feet, draws a metal tube that hums with power from his belt as he falls -

The second visitor to emerge is, perhaps, less familiar.

She makes up for this by being generally angrier and more powerful.

The third is between them in terms of both anger and power - the same sort of less familiar as the second -

She gets her own lightsaber in her hand and steps into a better defensive formation with her wife and grandson as she tries to figure out what the fuck is going on. 

She doesn't let her shock throw her off balance. She can't afford to.

But Tobi isn't really on the offensive here, and she needs information - and she'd never expected the man she saw in the Pure Land, the kind one who offered her another life - to come here.

She hasn't met the other two, but - if Anakin was the mirror of her across worlds - she can tell whose mirrors they are. 

And that means - probably they're on her side here. She hopes. (She's pretty sure Jakkou doesn't actually really care if Tobi dies, though she's not exactly aiming for her little sister; Jakuan's being more protective, but - this is a dangerous fight.)

Jakuan's shock does throw him off, though only a little. He gets a tiny bit of distance, Susano'o hovering at the edge of his mind, and stares at the newcomers warily.

(His heart's increasingly not in this fight. He doesn't want to go blind, but... He can't stand to see Tobi killed again, and seeing his little sister throw herself into a fight like this - )

(He wants to scream.)

That's never happened before. She doesn't want to show weakness - she backs off, her techniques work best with distance and her dear little sister makes that very hard - she needs information, and no one else looks like they have 'a fight to the death' at the forefront of their minds.

Her chakra shifts subtly. (Hiding techniques from her sister is... Very annoying, but she's been learning to do it over this fight.) And she asks, at the same moment - "Who are you?"

"Stand down first, children, then we will speak. I have no patience for this... sibling rivalry."

He takes a small step back.

"...I won't restart the fight. I'm not lowering my shields." He's keeping his attention pretty firmly on Jakkou.

She doesn't say anything, but doesn't seem about to imminently attack.

"Jakkou. Acknowledge that you heard me."

She inclines her head. "I heard you," she says, voice soft and even. "Though it is rude not to answer my question. Who are you?"

"I am Occlus. This is Ani, and Anakin. Tobirama- hello, by the way, it is good to meet you- is an alternate universe version of him, and you two," she points to Jakkou and Jakuan, "are the same of his brother and sister. Now. I know the three of you I am familiar with have been taught better than to be attempting to kill each other in such a fashion. Are you also capable of meeting that very low standard while in my presence?"

"It's good to meet you, too," she says, turning her gaze slightly toward the newcomers.

"I'm not trying to kill Tobi."

"I can keep to any truce terms."

She sounds and even feels perfectly honest.

"Can is not will, girl. Do not try to play games with me." Occlus has seen them all before.

Even if they get Jakkou to claim she won't attack -

Tobi's sister heard of honor once and apparently decided it was for fools.

"We're calling a truce," she says, flatly, sharpening her bubbling anger into her grandfather's calm ruthlessness. "If you break it, I will help Jakuan kill you."

"And if you don't like that - leave."

She isn't a perfect mirror of her alt, it turns out. Baby Anakin has never in his life felt this cold, focused this intensely - given off such an aura of threat. (Self control means her KI is only unleashed when she wants it to be. It's coiling around her now, heavily enough that weaker shinobi and civilians would be hallucinating their deaths.)

She observes Tobi for half a heartbeat, gaze hard. And then - "Very well."

Her KI has been a wild, vicious thing, snapping at Jakuan out of time with her actual attacks. It recedes now, and with it goes much of the haze in the air, a sensory shroud it's just now apparent isn't normal for this world.

It's harder to read her now, though. The shroud is pulled tight, concentrated.

"Thank you." She sounds more sarcastic than anything.

Her KI vanishes like it was never there, her emotions receding into calm analysis. 

"Good."

"Jakuan. You will not be attempting to kill either of your sisters. Is that understood?"
