"You think you're a big man, huh?" Danzo said with a huff
"Big enough not to need you" Kannin said, a grimace snaking across his face
"Well," Danzo began, "if you would stay in my lovely facility for a while, I'm sure I could persua-"
Before he could finish his sentence, Danzo saw Kannin make a single hand seal with his right hand, and he was gone, vanished, as if he was never even there.
"Dammit!" Danzo cried, "Didn't I tell you to watch his hands on the way over?!" He pounded his fist into the closed door in front of him, and shouted "Find him!"
When Kannin emerged on the outside, he immediately threw up. That teleportation stretched his limits a little, and he didn't account for the elevation change along with it--but he knew he didn't have much time. He had a vague notion of where he was since the Anbu didn't keep him from tracking direction or his hearing. He was about two miles away from Konoha proper, and he needed to close that distance; once he was back in a populated area, Danzo wouldn't try to do anything to him, and he could report it to Minato as well.
Kannin didn't waste time and darted in the direction he believed Konoha to be in. He couldn't tell if anyone was tailing him, but if he had to bet, there was probably a dozen of Danzo's operatives chasing him, and he had no idea what their capabilities were. Kannin wasn't going to take any chances and infused lightning chakra into his body flicker to speed up.
Just as Konoha was coming into view, three blurry figures flashed in front of Kannin, between him and the village, each wearing their own animal mask, some sort of bird on the left, a mouse in the middle, and a dog on the right. Coming to a stop, Kannin wasted no time in summoning Kiyo to his side; he hadn't brought Koseki out with him that day, so he'd need all the help he could get. Kannin also knew that every moment he spent fending off these three was a moment which allowed any other Root operatives Danzo sent to catch up.
"Now," Kannin said apprehensively, "we can do this this the easy way, and everyone goes home just fine, or," he continued, subtly putting his Flying Thunder God formula on Kiyo's tail, "we can do this the hard way, where I still get home just fine, but you three end up eating through a tube for the foreseeable future."
He muttered under his breath to Kiyo to make a break for Konoha while he dealt with the Anbu, and started weaving hand signs.
A tension hung in the air for a moment as all four of them were looking over their opponents, weaving hand signs or carefully drawing out kunai. Kannin would have to rely on his ninjutsu talents here, since Koseki wasn't with him, but that shouldn't be too big an issue for him, he'd always been pretty good with ninjutsu.
He smacked Kiyo on her side to signal her to run for it, at which she flew across the grass, and at that moment the three Root members flickered into a triangle formation around Kannin, and released their jutsus at once: the mouse threw four kunai in a square formation around Kannin, each with tags attached at the handle, which summoned in a puff of smoke a line of ink across the earth. The dog placed his hands on the ground, and with a slight rumbling of the soil, a strange, semi-opaque, greenish liquid pooled out from the ground and hardened around Kannin's feet. The bird seemingly did nothing, which drew Kannin's curiosity.
Kannin's first move was to try and teleport to Kiyo with Flying Raijin, but it failed.
'What!?' Kannin thought, 'It shouldn't fail! What the hell?!'
But then his vision fell to the kunai and ink on the ground, and he felt like he had an inkling of what was going on.
'Must be some sort of space-time sealing array, how clever...' he thought with a frown, 'And with this glassy substance locking my feet, I can't move. Plus there's the bird who hadn't done anything yet. They're quite coordinated.' Looking at his feet, he tried to figure out what the substance at his feet was, and came up with an idea, 'The green, glassy appearance looks like...jade, almost. If so, it's probably an earth release technique, so lightning should break it. As for the sealing array...water?'
It was his best shot, so he changed the jutsu he was going to use, and made the hand seals for his torrent jutsu, when suddenly he felt a sticky substance restraining his wrists. Looking down, he saw a spiderweb-like material covering his hands, and keeping him from making hand seals. He glanced over at the bird, and saw them leaning over with a bit of the liquid dripping down the chin of their mask.
"Y'know," Kannin awkwardly laughed, "this is kind of unfair--three against one and all."
His humor seemed to fall on deaf ears as the Root members remained silent, only nodding to each other as the mouse made the Tiger seal. With a hushed 'Seal!' Kannin's world turned black, as he fell out of space and time.
To the outside observer, the array of ink, with its vertices on the kunai implanted in the soil, collapsed onto the block of jade at Kannin's feet--and with a puff of smoke, Uzumaki Kannin, Konoha's Tempest, was sealed away, vanished from the world.
The three Root members might have thought that their mission had been complete, but there were two reasons they would likely fail in their endeavor, one reason they overlooked, and one reason they couldn't have known: they allowed Kiyo to escape, thinking little of the giant fox, and, more importantly, the moment the space-time sealing array separated Kannin from the rest of the continuum, a man in his high office was immediately alerted to it.
Minato was in the middle of a meeting with Kakashi and Tetsu when the two Anbu saw Minato's eyes suddenly widen, and the papers in his hand drop. The Flying Raijin formula he had placed on Kannin all those years ago hadn't disappeared, and when the sealing array activated, the mental sensation of that formula vanished conspicuously.
"Change of plan, you two," he said hurriedly, "something's happened to Kannin!"
"What?!" they both shouted at the same time
"Yeah, the mark I put on him vanished. It wouldn't go away even if he died, so he's been separated from the space-time continuum--sealed, as is likely." He rushed across his office and said, "You two, go find him. The mark vanished about a mile away from the western gate, try to see if you can't pick up Warai along the way, she'll want to help."
The two sat there in a bit of awe at first, prompting Minato to shout at them, "GO! Every minute you waste gawking increases the chance we never see him again! Go!"
