Disclaimer: I do not own Naruto.
A/N: Alright, I give up. Seems my reasoning for Death Reaper Seal is flawed. Well I am human and prone to mistake. That's it. Sorry if I'm not perfect and if people can't accept my reasoning guess it's my fault as a silly writer. However, I can say Sir Kishimoto didn't give much info on sealing Tailed Beasts into people on my defense and as a Naruto fan I will try to improve my writings and make things more believable. Enjoy!
Naruto went to the training place and found Minato with Jiraiya. They worked with Naruto for a better chakra control for the day and at the end of the day Minato showed hi something.
"Naruto, from tomorrow I want you to work on two techniques. Master Jiraiya will help you with them, the first one is called the Summoning Technique. And for the second..." Minato said as a blue orb appeared on his palm. "I want you to master my prized creation, the..."
"Spiraling Sphere" Naruto finished for him "Wo-hooo...I am gonna own the matches with that" Naruto was really happy.
"Now Naruto, I would like if don't use on an opponent who has almost no defense as it can be lethal. It is an A-Rank Technique." Minato lectured. "Other than that use it as much as you want."
"Promise Father" Naruto said and they all left for their home for the day.
[Next day]
"Alright Naruto. First I am gonna show you the summoning technique, then your father's technique. Use your clones with those techniques." Jiraiya said. "It will be a lot faster"
"Yes Pervy Sage" Naruto said.
Jiraiya pouted, "Naruto! If you keep saying that I will not teach you."
"Alright! Sorry Masted Pervy Sage"Naruto said bowing.
Jiraiya sighed. He was gonna have no luck with this kid. "Alright, you know about the Tailed Beast that lives within you" Jiraiya received a nod. "Well you do have unrealistic large chakra reserve thanks to him but you can't seem to draw out his power. I am gonna teach you that too."
Jiraiya bit his thumb and made some quick seals and cried, "Ninja Art: Summoning" and a large toad came into existence who had a scroll wrapped with his tongue and Jiraiya was riding on it's back. The toad gave Naruto the scroll and Naruto bit his thumb, writing his name with blood right beside Minato's and pressed down his hand with blood on all of his fingers. Naruto made some seals and cried, "Ninja Art: Summoning". A tadpole appeared.
Naruto, Jiraiya and the one Jiraiya summoned all sweat dropped.
"Concentrate Naruto! Unlike your wind techniques this needs a bigger amount of chakra."Jiraiya advised. "Alright, I'll show you the Spiraling Sphere now."
Jiraiya told him the first step of that technique and Naruto created 50 clones to work on it while he himself worked on Summoning. After some efforts he was able to summon Gama in an armored attire by the end of the day and after some days, he was able to summon Gamabunta the toad boss although it took almost more than half of his chakra reserves to summon him. When Gamabunta was first summon he did not accept Naruto at all.
"Cheh a mere kid able to summon me? I will not believe that. You have to prove it to me that you are worthy of me. Even if you did summon me only if you can prove yourself to me then and only then I might think of you as my minion" Gamabunta said. "You have to stay on top of me for this whole day".
"Fine Toad Boss." Naruto said and he jumped right on top pf his head. "My name is Naruto Uzumaki Namikaze. I will prove it to you that I am worthy of you."
Gamabunta jumped all day long and Naruto stayed on top of him with all his might. At the end of the day, just when he was about to fall he managed to create some shadow clones and pulled him to his head and he almost made it had the fatigue did not come, he mistakenly dispelled his shadow clones that were working on Spiraling Sphere. As he was about to fall, Gamabunta caught him with his tongue. Jiraiya noticed this development.
"So he finally did manage to get Gamabunta's approval, huh?" Minato said as he came right behind Jiraiya out of nowhere.
"Yes Minato. Seems Naruto did it" Jiraiya said.
Gamabunta jumped at them. "You know Fourth, your son might really surpass you. He merely wants acknowledgement as a splendid shinobi. I know that he summoned me completely on his own. To top it off, he had enough stamina to be on top of me the whole day."
"Thank you for your co-operation, Bunta" Jiraiya said.
"Yeah, having you as his summon, I'm sure he's thrilled." Minato said. ''Can you please take him to my home?" Bunta left with Naruto on his head and Minato said, "Alright Master Jiraiya, I know you have something on your mind. So what's up?"
"Fine, I won't beat around the bushes. Does the fox care for your son?" Jiraiya said.
"Yes I believe so." Minato said. "Although he won't give Naruto full access to his power yet."
"It has something to do with when he was sealed. Doesn't it?" Jiraiya asked.
"Let's just say the fox knows that Naruto is someone he can really put his faith on."Minato said."Even the beasts have feelings, they aren't some tools. When Naruto first accepted the fox as something good which I trusted him with, the fox granted him his enhanced senses and bonded their chakra. Naruto just have to earn his trust to draw out his full power."
"I hope you know what you are doing Minato" Jiraiya said. "I guess I'll trust the fox too if you and Naruto both do."
"Can you help him with that too Master Jiraiya?" Minato asked. "I will send in Tenzou"
"I will see what I can do" Jiraiya said.
After that day Naruto gave all his concentration to Spiraling Sphere. He did the first two steps within three days but he could never maintain it for some reason. Minato came up with an excellent idea. Minato created a shadow clone and both of them concentrated chakra on their palms and wielded a ball that was almost one third of his size.
"Aaah use a shadow clone to create it. An excellent idea"Jiraiya said.
"No! That was not it." Minato said. "I showed you that technique as it takes a lot of chakra and much more destructive than an average Spiraling Sphere. It seems your rotation and power aren't on the same level. Your power seems to be more so rotate it more and cover more area."
With that Naruto was able to master Spiraling Sphere and it was almost half of his body's size and more devastating than Minato or Jiraiya's. The weird thing was his Sphere was made of bright red chakra. Only three days were left, Yamato arrived and Jiraiya said, "I have one last thing I want you to master. I want you to contact the fox...to draw out his power. Your seal was made for that."
Yamato sat in front him and cried, "Wood Release: Foo Dog Heads". A series of wooden pillars emerged from the ground infront of him which had lit wicks on them. "Very well" Naruto sat down taking a meditating stance. Yamato cried once more, "Hokage Style Elder Jutsu: Tenth Edict On Enlightenment". Ten pillars shot from the ground around Naruto which had spikes on them. Naruto closed his eyes and found himself at his mindscape. He went to the gate.
"Hello foxy" he greeted.
"Hmph" Kurama said. "So you've finally come to claim my power, eh boy?"
"Well..er.." Naruto thought to be straight forward. "Yes I need your help"
"And why should I help you?" Kurama asked.
"Cause I need your help" Naruto said. "Like it or not, we share the same body and I need your chakra. If that's not enough, think of it as rent that you owe me and I will take your chakra as payment."
Kurama's eye widened. Can it be? It's almost just like before. "Very well foolish boy I will give you some of my power but you have to prove yourself to me that you are strong. Strong enough to wield even a speck of my power."
Naruto created a shadow clone and Red chakra emerged from the gate and enveloped the clone. The clone screamed in pain but did not dispel, skin peeled off it and a dark red chakra emerged. The clone looked like a miniature Kurama with red chakra skin, his eyes were glowing white.
"This is the jinchuriki form although it only has one tail worth of power. Now then defeat this and I may give you a bit of my power. You already wield the same amount of chakra as this one but you want this power right? So defeat it." Kurama said. "Or if you are afraid, leave me be and do not show your face."
"Oy fox! I told you not to underestimate me." Naruto said as he jumped at the miniature fox clone after making two clones. They both seemed to have same speed the but the fox clone had immense strenght. His punches would make Lee's mere scratches. The fox clone acme at him and swiped his hand which was sharper than a kunai. It kicked him followed by another swipe and flipped in the air hitting him with his tail and Naruto was thrown away. A red hand made of chakra shot from it's hand and hit Naruto crashing him into the ground. Naruto immediately coughed up blood. Naruto got up panting and shot forward after making some clones. He ducked when he was about to be swiped and jumped just when it's tail was about to hit.
Naruto immediately kicked him, followed by another kick and did a series of kicks while he dodged and kept him busy with the other clones as his hits landed. He kicked it away and cried, "Wind Style: Great Breakthrough" pushing the clone very far and made a almost 30 clones who all threw their shurikens and made the clone seal making a barrage of shurikens coming at the the clone. The fox shot forward and the thrown projectiles made little damage and all of the clones cried, "Wind Style: Vacuum Bullets". As the fox was slowed down for a bit, two Naruto's came from both sides and both had Red Orbs which were almost half size of their body. Both cried, "Spiraling Sphere" as they hit and the fox was crushed by such an immense force.
Naruto ran at him and kicked him upwards and two more clones and kicked him even higher and they jumped on top of him, hitting him with butterfly kicks and elbow stike and another jumped and did an axe kick. Just as the clone was about to hit the ground all of the clones made spiraling spheres and hit him and Naruto made one as the fox crashed on it and he dispelled and the fox crashed at the ground. Naruto was panting hard. Using so many techniques at once almost drained him dry, he couldn't even move should something happen.
"Impressive. Very well." Kurama said. "You from now this day will be able to access this power worth of two tails. Beware though if you attempt to use more, you will lose control to your instincts. Now go and let me sleep."
"Thank you very much for your help Fox"Naruto said. "I promise I won't use this power for evil." With that he left from the dreamscape.
