In a half build bridge covered by mist six figure can be seen, four of them are Sasuke,Sakura,Kakashi and the client Tazuna a grey-haired, bespectacled man with a large beard and dark eyes.
On the opposite side there are two figures, one was a 15-year-old boy with long black hair, that is gathered in a white bun holder, while two locks of his hair fell loose framing his face, bound with metal hair cuffs at the ends, pale skin and large, dark-brown eyes, and a slender frame.
And is outfit consist of the standard Kirigakure pinstriped outfit which stopped at his knees, over this he wore a green haori with white trimmings, and around his waist a brown sash with a fringed trail wrapped around his waist twice. He also wore light-brown platoon sandals with straps in the same colour as his kimono and nail polish on his fingernails and toenails in matching blue-green colour ,he also wear a hunter-nin mask on top of his forehead protector, which is white with thin, curved eye-holes and a red wavy design in place of the mouth, as well as the Kirigakure symbol etched in the top.
That is Haku, the other is a tall and noticeably muscular man with light grayish skin, short spiky black hair, dark brown eyes, and small eyebrows. He is wearing bandages like a mask over the bottom half of his face,and he wear his forehead protector sideways on his head,
He is shirtless, with his chest only covered by a belt to which he attached his Kubikiribōchō,a large broadsword, as tall as a full-grown man, shaped like a butcher knife. The blade itself has two cut outs, a circle close to the top and a semi-circular one nearer to the handle, the former of which is aptly fitting the sword's purpose of decapitation, wearing baggy pants with the striped pattern typical of Kirigakure and mimetic wrist-warmers extending up to his elbows, with matching leg-warmers.
He is obviously Momochi Zabusa one of the former seven ninja swordsman of the mist who looking at Sasuke who a few moment earlier destroyed his water clones told to Haku "It seem that a rival appeared heh Haku?" where Haku replies "it does indeed"
Meanwhile Kakashi "it seem that my hunch was correct, Sakura it seem that we are lucky that your brother gave you a mean to call for reinforcement" and Sakura says "Yes, Ren sometimes is kinda overprotective but this time it help" and Sasuke with emo-power "I take the masked guy, tricking us with that stupid act i hate bastards like that the most"
Soon Sasuke and Haku star fighting ,while Kakashi tell Sakura to guard Tazuna, Haku make one-handed sign and use Sensatsu Suishō(Thousand Flying Water Needles of Death) forming thousand of water needles around them, but Sasuke was able to evade by focusing chakra in the legs and then kicked Haku.
But then Haku decide to get serious and use is kekkei genkai, is ice release and use the technique Makyō Hyōshō(Demonic Mirroring Ice Crystals) that creates several large mirrors out of ice, which he surrounds Sasuke within, and Haku enter one of these mirrors making Haku's reflection appeared in all of them and soon star attacking Sasuke with his senbon causing many cuts.
Seeing that the situation wasn't good Kakashi decide to intervene but was intercepted by Zabusa, and so Sakura decide to trow a kunai at Haku who block it without problem but then was it by a shuriken trow by an incoming Naruto leaving a scar on Haku's mask.
Naruto who's like an idiot put himself inside the technique of Haku letting go of the only advantage he had and so Haku starts again to try to make Sasuke and Naruto similar to a hedgehog, Meanwhile Zabusa enhance his Kirigakure no Jutsu(Hidden In The Mist Technique) while Kakashi unleash his Sharingan but is wounded by Zabusa who's aimed at Tazuna.
In the meantime Sasuke in trying to follow Haku movement unlock is sharingan but in the end is defeated by Haku who aimed at Naruto , and Naruto seeing Sasuke end enraged unleash a torrent of red chakra that for a second takes the form of a fox, with the coming of the red chakra some change happen to Naruto first his eyes turn red and the pupil become slit similar to a beast and more important hi wound start healing.
Kakashi noticing the change decide to not hold back anymore and summon is ninken who following Kakashi's blood on Zabusa where able to bite and hold him still, and Kakashi star using is only original jutsu cladding his right hand in lighting.
On Naruto side thanks to his power up Naruto was able to hit Haku in the face breaking his mask,when he was about to finish him he recognize Haku and stop but Haku convince Naruto who's still believe that Sasuke is dead to finish him but at the last moment notice Zabusa plight rushes to save him.
And as Kakashi's chidori was about to hit Zabusa but Haku who rushed there was hit instead and Zabusa took advantage of that moment to try to cut Kakashi who was able to evade and put Haku body out of harm way.
It was at that moment that Ren came to this scene "Shit, did i come too late"why is Ren alone ,well when he felt the Kyuubi chakra he knew that they were going to be late so he told Hayate-sensei that he will rush ahead as he knew first aid and could help the wounded.Then Ren rush to Haku side and checking on him 'He his barely alive, will die any second if I do not move" and with a green glow on his hand he started using Kaido.
Kaido different from healing ninjutsu restore chakra reserve and use the chakra of the wounded to then restore the bodies, with Kaido as long as one is not dead he can still be saved, of course Ren only did first aid so that Haku doesn't die, then went to Sakura that was crying near Sasuke and checked on him.
"Sakura stop crying please, Emo-boy is still alive and he isn't in danger, dress his wound and he'll be fine"
