Batted and bruised all over, Naruto could no longer continue his fight with the Akatsuki boss, but the Kyuubi spirit inside him was somehow encouraging him to carry on. He was exhausted physically but not mentally. Facing a guy who can read his every move and has learnt every skill including forbidden ones is no easy task as he can pull off different techniques at the least unexpected.
"You have a choice, you can surrender now and you life will be spared, or you can continue in that sorry state of yours and die of a painful death, which do you choose?" Yagami taunted, still suffering a little from Itachi's hyposis. Naruto knew Yagami didn't want to cause any harm, but due to Itachi's hypotizing technique he was somehow triggered into fighting him. With boosted determination, a huge amount of chakra suddenly seemed to replenish his strength, as if he was rejuvenated again. Yagami could not believe what he was seeing right in front him: Naruto with the awakening of the Kyuubi Spirit.
"This will be interesting...Suiton: Suiryuudan no Jutsu!" In an instance the defeated water clones' puddles began to form into a shape of a dragon and came rapidly towards Naruto but he was able to stop the ninjutsu from doing any further damage. With the Kyuubi's chakra supplied, Naruto charged up for another Rasengan attack, Yagami engulfed his hand with the Amaterasu flame, waiting to see his opponent's next strike.
"Yagami, this is the power of the Kyuubi! With it I've unlimited chakra no matter how much you asborb from me, prepare for your defeat, RASENGAN!" Naruto quickly wasted no time and unleashed the Rasengan towards Yagami. Yagami on the other hand seemed very confident even though he was facing the legacy of Konoha, with that the black flame in his hand seemed to grow bigger and when the time was right, he defended Naruto's Rasengan with his Amaterasu hand. Naruto, knowing no one could survive that attack with Kyuubi's chakra, was shocked to see his fist grabbed by his opponent's hand surrounded with black flames. Of all opponents who had encountered his Rasengan, so far Yagami was the only one who could guard against it, and also the unique ability to control his Amaterasu flame unlike Itachi who releases a huge amount of it, straining his chakra limit. But Yagami was the complete opposite, he was somehow able to control the power of the flame and able to release it at whatever amount he wanted. It was a clear message sent to Naruto; Yagami was determined, and being the Akatsuki boss he will stop at nothing until he finished his mission.
"I will show you another series of attack, this type it will all be water elemental. Get ready for the first! Suirou no Jutsu!" Water remains from Yagami's previous attack began to create a large sphere of water, that holds the opponent inside it. Naruto, realizing he was being trapped, punched and kicked his way out of the water prison but to no avail. Knowing that the drawback is that user must keep contact with the sphere to keep the prison working, Yagami let go of the water prison at the edge of the branch, allowing the water to splash to the ground with Naruto along. Just before Naruto fell to the ground, Yagami continued his chain attack. " Suiton: Daibakufu no Jutsu!" The puddle than becomes a large spinning pillar of water, sending it towards the opponent. Naruto was struck hard from the back and had no time to evade it airborne. Finally alert, Naruto secretly took out a kunai from his pack as he awaited what Yagami would do next. The Akatsuki boss wasn't done with him yet; He had one more final chain attack. Performing his one-hand seal again, all Naruto could do was watch from a distance and prepare for the unexpected. Yagami assured himself this would be the last of his elemental chain attacks, calling out to his opponent. " How long do you think you can hide? Wait till you get a load of this final two chain attacks, Kirigakure no Jutsu!" Immediately the area around the two of them began to blanket in a thick fog, confusing the senses of the enemy. Naruto's visibility of tracking down his opponent were vanished and he only had to rely on his hearing and smell. With Naruto out of sight, Yagami took out a shuriken before doing the 'Shuriken Bushin no Jutsu' technique where it multiples a thrown object into many exact replicas of the original, that all do real damage. Not knowing where his opponent would ambush from, it was too late as the shurikens all struck Naruto from the back. Heavily injured, Naruto hid himself within the trees as he watched the fog disappearing, revealing the Akatsuki boss standing in the middle of the forest. As the Kyuubi's spirit began to heal Naruto's wounds, he leapt out from his cover, alerting Yagami but instead he stood with his back faced towards Naruto. The arrogant and brash genin took out his kunai, ready to stab his opponent, but in a spilt second, time seemed to stop. There at Naruto's abodmen was Yagami's hand with the back flame surrounding; it was the five element seal(Gogyou fuuin) where Orochimaru had used the same technique on Naruto before. Using an odd number seal against the Kyuubi's even numbered seal, it causes the spirit to lose effect. As a result Naruto becomes unable to control his chakra, and cannot tap into the chakra of the Kyuubi. It was the end of the line for Naruto, with both his normal and Kyuubi's spirit chakras disabled, and with a limited skill of Taijutsus he had, all Naruto could hope for was a miracle...
