Naruto's growth..
"Are you kidding me! How could you possibly think I would s-" Jiraiya cutoff Tsunade and continued "he's no more a kid you used to know, he's strong now."
"But Jiraiya we are talking about Akatsuki they are S ranked criminals. Last time when Itachi and his partner came to the village they took down three jounins like they were nothing" Tsunade tried to make her point.
"Tsunade whatever the report Kakashi may submit about Naruto, know one thing he is strong" Jiraiya said in a serious tone "and one more thing. Two months ago we came across Itachi Uchiha and Kisame Hoshigaki, and Naruto went toe to toe with Kisame"
"What?!" Tsunade was shocked to hear this "h..how's t..this possible .."
"Yesterday I had a spar with him and he overpowered me. I had to use my sage mode to defeat him and even in my sage mode he held battle for an hour or so.."
"Wh..What? A..are yo..u serious?" 'To take on Jiraiya in his sage mode, that's..' "ok so how strong Naruto is?" Tsunade asked Jiraiya with curiosity.
"Well to be frank there is no person alive in this village to defeat Naruto, that includes you too" Jiraiya said proudly.
"What about you? You defeated him.."
"But that's because of sage mode and within 5-6 months he will surpass me or even the fourth Hokage Minato, his father!"
With Naruto..
"Your task is simple! you both have to get these bells before sunrise"
"Kakashi sensei you sure you want to fight me and Sakura at the same time ?" Naruto asked before their test began.
"Yeah!" Kakashi said lifting his head band and revealing his sharingan "I warn you, come at me with intent to kill or else you'll never get these bells"
After a moment ..
"Here I come" Naruto shouted throwing some shuriken at Kakashi who simply dodge it by ducking and replied with some of his shuriken. Naruto simply jumped in air to avoid it. To get Naruto, he threw some more at him, since Naruto is in the air he can't dodge it. He simply made a clone to move himself out of the way. As soon as he landed the clone transformed into giant shuriken and was just going to hurl it at Kakashi but he caught him.
"Your haste hasn't changed" 'He's improved from back then' Kakashi thought 'and not only that'. There stood one more Naruto holding kunie at Kakashi at point blank range, ready to poke him. "Alright start!" Said Kakashi and puffed out in smoke.
"Argh! You big dummies! You lost him!" Sakura shouted at Naruto. Before Naruto could say anything she started searching for Kakashi
"left.." she tried finding his presence on her left after five minutes she turned right "right.." after sometime she again turned "behind.." and then she looked above "above.."only to find blue sky and nothing else.
At this time Naruto gave a confused expression "Sakura?! What makes you think he'll be above us?"
"Don't act smart, you idiot! if you know where he is, then just spit it out" Sakura said with an irritating tone.
Hearing Sakura's words, Naruto's head went down and like in a depression tone he pointed to Kakashi who was hiding underground.
"What?! There's nobody.."
"He's hiding underground.." Naruto again said in the same tone of depression.
"What.. below!" Sakura shouted and punched the ground and *BOOM* everything shattered, the ground was destroyed (same as that shown in series).
"Gyahh!" Naruto shouted controlling himself "Eh?!" Naruto's doomed expression changed to shocked one.
'w..what insane power.. I don't think granny just taught her medical ninjutsu.. i think i should stop playing around Sakura or she'll kill me'
"Found you! Kakashi sensei!" Sakura smiled at Kakashi.
Kakashi wasn't shocked at this, he had known her strength all along because he went on many missions during these years.
Kakashi jumped and stood on a plane surface "since when did you figured I was hiding underground and how did you know my location?" Asked Kakashi.
"I knew it all along. Since we came here, you went underground using Earth style, leaving aclone to fight and since you used earth style, it didn't left a hole.. am i right sensei ?" Naruto explained everything.
"well done Naruto, you really have matured!" Kakashi Appreciated Naruto "alright then.. this time I should do something on my end too"
Kakashi was forming a hand seals for preparing a offensive technique but in an instant Naruto appeared in front of Kakashi and punched him 'so fast.. there's no time to avoid it.. must block' Kakashi thought
"What?! So fast!" Sakura was shocked, she didn't even see him moving.
Kakashi barely blocked by his right hand. Naruto started punching and kicking him which he managed to block, then Naruto side kicked him with his full strength, Kakashi saw through this so he brought his both the hands to his side to block it. Just as he blocked his kick, he was thrown crashing several yards.
Kakashi got up and felt pain in both of his arms "ahhh!"
"you should have taken me seriously" Naruto taunted Kakashi "I told you to take Sakura by your side sensei.."
'He's strong!.. even though I blocked his attacks, they were too strong and inflicted me more damage than I thought' Kakashi stood up "fine then, I think I should get serious too.."
"Sakura go and help him.. fight from his side" Naruto said "and don't argue, I'm dead serious"
"Fine but don't regret it!" Sakura said getting angry at Naruto.
After healing Kakashi, Sakura took her stance to fight "that won't be necessary Naruto. Sakura join him, this is going to be little bit messy around here.. GO NOW!" Kakashi said sternly.
She has seen Kakashi fight seriously, so without a question she went to Naruto's side. Kakashi stood there and did a hand sign, Naruto could fell that he was concentrating chakra in his left eye.
"Could it be.." Sakura was shocked to see Kakashi activate his mangekyou sharingan.
"Don't worry Sakura, I won't use it, this is just to anticipate Naruto's attacks"
"Hehehe.." Naruto laughed a little
"Get ready Naruto!" Said Kakashi and formed hand signs "FIRE STYLE: FIRE BALL JUTSU" a giant fire ball shot out of Kakashi's mouth. Naruto also went through hand signs and raised his hands in front of him "WIND STYLE: JADE WIND HURRICANE" a wide current of wind with great speed shot towards fireball.
Both Justus collided and exploded forming a giant sphere of fire engulfing whole area, but the collision seemed to be more towards Kakashi while the place where Naruto stood was not even touched.
Seeing the incoming blast Kakashi immediately formed hand signs "WATER STYLE: WATER VORTEX JUTSU". A vortex of water big enough to engulf the explosion shot towards Naruto and Sakura. Evaporation of water decreased the visibility and before they could even see it vortex hit them, they were sent back crashing into woods clearing the whole area.
After a moment when everything settled down Naruto and Sakura stood up taking support of tree. There was a blue aura in front of Sakura, it was a wind shield created by Naruto to protect her. Even after use of wind shield, jutsu inflicted too much damage.
Sakura started healing Naruto without caring about herself "don't Sakura! Heal yourself first, don't worry about me I'm just a clone" said Naruto grabbing her hand.
"You protected her at the last moment, Naruto! But you shouldn't have used that wind style jutsu in the first place because wind is inferior to fire, it only made flames more intense.." Kakashi explained
"That's precisely why I used more stronger jutsu, as you can see it was much more intensified and was directed towards you, but I never thought you would use a giant vortex.." after saying this Naruto vanished in smoke and the two Narutos came to Sakura's side "knowing you Kakashi sensei, you would have interpreted the same thing if it wouldn't have been me, right sensei?"
'He's getting more like you.. sensei' Kakashi thought
"Take care of Sakura, I'll get the bells" Naruto said to the clone and dashed towards Kakashi 'i'll have to finish this before I run out of chakra' naruto thought as sun was going down.
After a while of taijutsu fight between kakashi and Naruto, he came to know that this was a clone too. He had to dodge his every attack cause blocking caused damage. Naruto pushed him at one end and they were standing on water "WATER STYLE:WATER DRAGON JUTSU " Kakashi shouted.
A dragon formed out of water, shot towards Naruto. He jumped in air to avoid it and took out some shuriken in both hands. He threw shrunken in left hand, in a parabolic path to hit Kakashi from his side, he then threw another pack of shuriken straight at him which was in his right hand. Immediately he brought out some kunie and threw them too aiming nowhere in certain.
Kakashi anticipated Naruto's attack. Naruto blocked his one side and he can neither jump back to dodge it as second wave was just straight on him. Kakashi jumped to the other side on ground. He then noticed that there are some kunie coming towards him. Kakashi had no other choice but to break his jutsu and block the incoming cause there were too many that spread across wide area.
After the attack died, Naruto stood in front of Kakashi, panting. Both of them were tired after an hour of fighting. Sakura and Naruto appeared from the forest and attacked Kakashi, their attacks were synchronized and Kakashi was having having problem dodging them. However Naruto took it slow very slow on Kakashi this time he didn't hit him hard but he was fast to attack.
"Just.. one.. clean shot"Sakura was trying to get a clean hit on him but she wasn't able to, she tried to punched him in face but he just moved sideways only to get a kick from Naruto. Kakashi grabbed his leg, pulling him a little, Kakashi swing him. Naruto collided with tree and puffed out in smoke, suddenly Naruto came to place where his clone was hit, grabbing something he walked to Sakura's side.
Elsewhere...
Naruto was walking down the streets of konoha "wow that was amazing! Ichiraku ramen after these many years.. I'm stuffed... I don't know how my test is going on but I suppose he'll do it.. he does have more than half of my chakra".
After a while of walking "I didn't get any update after the clone was dispelled, there were two of them but still.. may be I should go and check myself.." Naruto suddenly felt a person that seemed to be following him "eh?!". He disappeared in a blurr and reappeared behind that person who was hiding behind a pole.
