"Kisame, what I did at the mountain was to protect the survival of the Akatsuki clan! You must understand this, I'm already regretting losing you as a partner. Please do not do this!" Itachi shouted towards his ex-ally. Yagami could see from his Makekyo Sharingan that the fear inside Itachi was beginning to build up; a sign of weakness. Yagami knew this would be the best opportunity to launch a surprise attack, but his chakra was still not enough. All he could do was to let Kisame battle Itachi while he slowly regained and hopefully, catch Itachi unaware.
"You left me to die, along with Sasori and Deidara! I won't forget that and forgive you!" Kisame took out his Samehada and lashed it towards Itachi but missed barely by a few inches. Itachi unsheathed his kantana to block the next strike from the hidden mist tribe missin nin. Kisame was a fierce opponent in battle, Itachi saw his partner's previous encounter when the both of them were in Konoha fighting off Azuma & Kurenai, along with Kakashi and Maito Gai. He was a former member of the Hidden Mist's village 'seven swordsmen of the mist', along with the late Momochi Zabuza. Wielding his one of a kind Samehada made entirely out of shark teeth, even his scary personality seems to develop similarly, he was also nicknamed 'the man with the most chakra' as his Samehada ate up his opponent's chakra.
"Suiton: Suikodan no Jutsu!" the blood left by Yagami took the form of a shark and went towards Itachi, barely knocking him to the wall. . This jutsu utilizes any liquid to attack the enemy with strong water bursts in the form of a shark. Before his opponent could recover, Kisame unleashed another.
"Suiton: Goshokuzame!" five sharks swam beneath Itachi's feet before exploding into powerful blasts of water. Itachi had hardly even laid a scratch on Kisame and was beginning to feel exhausted. Yagami, still in the midst of recovering, taunted the downed opponent. "What's the matter now Itachi? I see fear has come to your senses! You're becoming weak!"
"No! I'm the ultimate!" Itachi got up and focused his chakra as fast as he could but Kisame swung his Samehada across and in an instance the blue chakra flame around Itachi was gone. Realizing that his chakra was eaten up by the blade of Kisame, Itachi than went for his Sharingan. Anticipating, both unleashed the same jutsu just at the right time. "Suiton: Bakusui Shoha!" Two massive blast of blood came pouring at each other but did not cause any damage to the two contenders. As the rain of blood poured over them, Yagami was already fully charged, but he didn't want to ruin this fight between the two former comrades, instead he signalled to Kisame for the final strike. He raised the Samehada and striked at the downed Itachi, leaving a big wound with tremendous amount of blood gushing out. The sound 4, trembling at the sight they saw, immediately released the seal and went to attack Yagami & Kisame. Sasuke could not bare to see his brother get harmed anymore and joined the fray. In the end Yagami, Sasuke and Kisame were left victorious but suddenly Kisame was stabbed in the chest; the blade of the kantana held by Itachi. Shocked at his amazing recovery, he pulled the blade out to see his former partner dead again. Realizing that the deceased was a clone, Itachi gained back his confidence.
"You really underestimate me brother, I am the real master of the Makekyo Sharingan! I know no FEAR, only HATRED!" Soon a storm began to brew. Heavy drops of rainwater immediately drenched the whole village. And there stood the three Uchiha brothers, all soaked and wet, among the bodies of dead and injured shinobis. It was down to three brothers, no interference was there to disrupt their personal dispute, for the vengenace of the late Uchihas, Yagami & Sasuke represented and for the existence of Akatsuki, all left for Itachi.
"This would be interesting, you ready Sasuke?" The determined Uchiha nodded in agreement as all three activated their Makekyo Sharingan, the highest level of their clan bloodline limit jutsu. Three powerful fighters were about to be engaged in the most historic battle in Konoha village; Sasuke with his determination and series of skills were aided with his long-lost brother Yagami, the shinobi who knew every technique there is to know, and Itachi; the individual with the ability of hyposis. As a flash of lightning and sound of thunder followed, the three rushed towards each other.
