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.
"I don't know. Tasara thought you could track him; if you can't, you can switch off with her to fight the clones while she finds him."
"Come on, then - Shisui, you should stay with her or me, the Uchiha are the main point needing defending anyways - "
She shows the other girl what to do, and Anneia sets to with a grin.
"The clones are being controlled, right? They're not independent actors?"
"Depends on the type. Most advanced clones are independent actors. Some very advanced clones allow synchronization of experiences. All clones as advanced as the shadow clone will return memories to their creator when destroyed. These appear to be capable of sharing information between themselves on at least some level."
"All right. I should be able to track the transference at least, then. Wait here. Follow me if I move." She leaps elegantly into the air above the district and hangs there, a bright shining point in the sky.
She's been fighting these clones, she knows what they feel like, what their magic feels like. Their essence does move, she just needs to see it. Her eyes begin glowing brilliantly as she scans the battle for the tell-tale tracery.
Not all of it seems to be going into this dimension, or in the same direction - whoever it is seems to move around a lot, instantaneously. The information moves immediately, though, and the most recent location is to the far west and north, just short of Fire's border with Plains Country.
Too far for her to engage without unacceptable casualties, damn. She lights up the nodes she can see for Anneia to engage and returns to the ground to share her information.
"That area's mostly deserted, but if he's able to move like that, we don't actually know he can't just teleport across the continent." Her brow furrows. "How quickly could you move to his location?"
"Faster than we could go, but he can probably leave faster than that. He won't be magnitudes more powerful than his clones, though - maybe at most ten times as hard to kill or capture."
"Maybe ten minutes, then, but that's risky. I don't think trying to chase him down at this distance would be a good use of my time."
Deep breath. "Yes. That's... Reasonable. Better might be to find somewhere he intends to be. Which would involve discovering his plans."
"Is there any reason to keep the clones around in service of that goal or can we finish dispelling this attack first?"
"Shisui might want to try and hypnotize one. Which should hopefully have already occurred to him..."
Who is indeed testing if Kotoamatsukami works on clones. Or, better, can transmit from a clone to the original. He's gotten one that froze, started shaking its head, and then was forcibly dismissed.
After he notices Itachi he signs, where no version of their opponent can see, 'I-za-na-mi? Your father can.'
'Try,' she signs back, and darts to find her father - and see about echoing the Uchiha's ultimate genjutsu through a clone-link.
And her father's injured, badly, but he's willing to try, willing to risk his sight permanently - he has her carry him to a section of the battlefield, meets the clone's eyes - his eyes close - and every single clone on the field dismisses.
"I don't think it took well; it might not change his fate," Fugaku rasps. "But he should be frozen while he fights it."
Itachi nods, turns, and, behind her - "I'm proud of you," her father says. "Go. Get your brother."
She takes off to find Tasara rather than answering.
"The hypnosis didn't. My father had a technique that usually traps the target in their own mind, repeating their actions until they choose to change. It was cast through a clone, so he might be able to fight his way through without repenting, but he should be frozen in the meantime and his clones were all dismissed, which might hopefully give us enough of a window to find him."
"Ten hours if I sprinted." Which would be stupid. "I could possibly do fewer." Which would be even worse.
"Stay here. Have Anniea help with cleanup. I'll bring him back."
She lauches herself into to sky and accelerates toward the marked position, a luminous streak leaving cracks of thunder in its wake.
