Knowing their positions were compromised, Kiba knew he had to move quickly or the initiative would be lost. A quick scan of the rock around the entryway revealed the opportunity he needed. Throwing an explosive tag kunai at the roof of the cave caused a significant amount of rock to break loose. The large man shoved his elder outside, away from the debris, leaving himself and the young woman inside.

From behind the wall of rock, that nearly blocked the entire entrance, the old man's voice was barely audible.

"There are three in there with you. I'll join when I can."

As Kiba began to rush the two strangers remaining his mind went back to his ANBU training. With Akamaru and Karui on either side, his attack would most certainly be able to flank and defeat whoever he charged first. As his eyes quickly scanned his opponents, Kiba thought about which of the two would be more important to eliminate first.

The large man wore a vest under his cloak that he was still throwing to the ground. With his arms like that, any counterattack made would be less elegant. Kiba's eyes noticed the large tattoo on his chest, his attention then moved to the glitter of knives and swords kept beneath the vest. A face like a piece of stone, his hair was shaven except for the back, which was divided into a series of small ponytails. Kiba decided he was a hard man, who would not go down easy.

Looking to his right, Kiba saw the girl. Her hood, sewn into the neck of her kimono, no longer covered her face and Kiba saw that she was no older than he or Karui. Her hands were already moving together to form a chakra seal, which meant she was actively working on a jutsu.

'Do I attack the immediate danger, or take the opportunity to attack a preoccupied foe?'

Too often had Kiba experienced an unexpected attack from his teacher Kurenai when she looked distracted. Far too often had he been knocked down in his overconfidence to let it happen again. He rushed at the girl, intending to catch one of her legs. When he grabbed her left foot, Kiba brought his fist down hard against her knee not expecting that he would be the one to cry out in pain.

"Doton: Domu."

Her hands were held together in the serpent seal, and her skin took on an even darker shade of brown that it already was. The technique was simple and clever; enhancing a weapon with elemental properties was no different from enhancing your own body, and hers was now as hard as rock. With a flourish she whipped the excess of her kimono around her arm, and punched down on Kiba's low position, but Kiba deftly dodged to her side.

On the other side of the room, Akamaru broke his disguise and jumped at the vested man. The surprise attack left a sizeable gash across the side and back of the man's head, taking off several of his braids. Too well trained to get angry, he drew a short sword and a kama from the inside of his vest and began circling the ninken.

Kiba had little time to notice his companion dog's fight as his own kept him busy. She was a fierce taijutsu user, her hardened body enhancing her strikes; after blocking two punches Kiba thought it better to focus on dodging. Backed into a stalagmite Kiba dodged a punch aimed at his head and kicked her non-anchor leg out from under her. Rather than falling, the agile woman tumbled and flipped back onto her feet, right in front of Karui's position.

Karui's sword moved like lightning, and it was shining as vividly. The woman jumped aside, gripping her left shoulder, spitting out a non-verbal curse. Her skin lightened, it seemed as though Karui's attack broke the technique.

"You're getting sloppy Akie." Karui said to the young kunoichi.

"And you're still as likely as not to attack from behind Karui." Akie replied.

Deciding to help Akamaru, Kiba ran towards the back of the large shinobi and rolled under the kama thrown at him. Landing next to Akamaru, Kiba formed his familiar hand seals.

"Jujin Bunshin."

Akamaru turned into a clone of Kiba and circled around to the shinobi's other side. Kiba took his chance when the man's back was turned to him. In a spin, the larger man moved faster than he had a right to. Kiba's took a glancing hit on his left forearm, but the strike caused the shinobi to lose his grip and the sword dropped to the ground. Akamaru pressed an attack as Kiba reached into his pack for a Blood Pill.

"Doton: Doryuso."

Karui's sword slashed at the stone spikes that formed as she charged at Akie. The kunoichi's hands flew as she made seals, and before Karui could attack again the cave began to collapse on all sides around Karui.

Akamaru's high kicks prevented the big ninja from pulling out another weapon. After taking another hit to his head, opposite to the cut, he was taken down to a knee. Kiba moved in and grabbed the larger man's arm; applying a submission hold he learned from ANBU, followed by a sharp twist and a tug caused the shoulder joint to dislocate. Looking over his shoulder, Kiba saw Akamaru blitz Akie, slamming her against the wall.

The rocks blocking the entrance to the cave exploded inward, Kiba ducked to avoid getting hit by them. The old man, eyelids closed, seemed to be assessing the situation without even having to look at it. Karui came at him, sword arcing with energy. His head slowly turned to regard her, and with a hand seeming to move in slow motion he grabbed the blade. Metal snapping in his grip, thirty-five centimeters of the sword's tip broke off in his hand. He then attempted to stab Karui with it, but she jumped back to avoid it.

Kiba moved in simultaneous to Akamaru, intending to get behind him. The older shinobi took a wide stance and punched at Akamaru, who was still four meters away. Yet Akamaru looked to take a hit and fell to the ground at the elder's feet, breaking the bunshin effect. Turning towards Kiba the older ninja's eyes finally opened, the pupils seemed wide and flat and they had an eerie yellow glow to them.

"Sage eyes." Kiba whispered as he realized what he was seeing.

A pain sprang in Kiba's breast. He found himself on his knees gripping the tip of Karui's sword that had been thrown at him, a glow of chakra faded as he grabbed it.

"Kiba!" Karui screamed from the other side of the room.

Vision in a spin, Kiba noted the other two shinobi were rising from their positions. Karui rose and turned on the power generator, which caused the suspending lights to flicker on brightly. A few shuriken from her brought down sections of the cables which caused several dangerous tendrils of electricity to whip about the room.

Akamaru ran over to Kiba, and grabbing the ninken's back helped steady him on his feet. The Sage paid no heed to the wires as he walked towards Kiba, stopping only to pick up the short sword fallen to the ground. A mist rose with each step he took; what was first a sheet of fog soon became a cloud. The sight of it sent a shiver down Kiba's spine.

Knowing the situation had turned against them, Kiba motioned for Akamaru to cover Karui. The Inuzuka flash bangs he threw were practically deafening, but he hoped the attack would buy them the few seconds he needed. Next he used a smoke bomb, which covered the entire breadth of the cavern. Picking Karui up Kiba limped deeper into the cave, supporting his weight on Akamaru and Karui. Throwing his last smoke bomb behind them Kiba found they were at a fork in the cave. Two forks were neatly carved out, as though part of a mine, the other was natural and barely big enough to walk through.

The cries and shouts of their pursuers behind was followed by the crash of collapsing stone. Taking the tunnel to its end Kiba saw that it led to a massive fissure which tapered up until it closed; the opening below seemed made of the very black of midnight. When the passage behind started to fill with clouds Kiba took a chance and grabbed Karui. Giving a command to Akamaru, Kiba threw the grappling hook before jumping into the dark.

I decided to be cheap and just use techniques from the anime/manga.
