In a heavily forested area a good distance away from Konoha stood 4 figures with a man and a woman lying unconscious in the ground beside them.
The 4 standing figures were all males and consisted of a man, a teenager, and a kid and they all have the usual Uchiha appearance of black hair and black eyes but with different hair styles, while the last one; another kid had short blond hair and blue eyes.
They were Fugaku, Shisui, and Bakorio surrounding Naruto as if waiting for something.
As for the unconscious man and woman, they are prisoners they brought with them for a very important purpose!
"Minato, Kushina let's begin" As soon as I said this, inside Naruto's seal space both Minato and Kushina started making hand seals.
To be specific they did the hand seals for The Spirit Transformation Jutsu!
Tiger → Ram → Rat → Horse → Boar → Hare.
When they finished, their souls became covered in a blue aura and they felt they could leave the seal space without getting pulled inside the afterworld, better known in the Naruto world as the pure land.
Soon Minato and Kushina left the seal space and appeared in front of us.
Fugaku and Shisui stared at them in a daze still finding the situation unbelievable but they quickly nodded at them in greeting and Fugaku said "Minato, it's nice to see you again"
Minato gave his usual sunny smile since he was really happy to meet this old friend that always supported him when he was a Hokage "It's good to see you again Fugaku-san" then he turned serious and asked "Are these the criminals you chose for the mission?"
Fugaku nodded back to reassure him "Yes, we carefully picked these two for their heinous crimes of kidnapping villagers from the land of fire and selling them to nobles of other lands as slaves so you don't need to worry about using them"
What Fugaku meant by using them is related to the use of the Spirit Transformation Jutsu, This S Rank Jutsu created by the second Hokage Tobirama has many uses.
From allowing its user to leave his body and become a spirit impervious to physical harm or transmitting information regardless of the distance or transferring chakra from one person to another the way Dan Kato did on Tsunade during the fourth great ninja war.
It also allows the user to locate anyone as long as they have seen them before and know their chakra signature regardless of the distance.
However, there's another application of this Jutsu and that's it allows the user to possess the body of a target. While inside, the user is able to suppress and collapse the victim's spirit, killing them or simply gaining control of the said body for a period of time.
The downside of this Jutsu is that you can't possess a dead body or kill your possessed target by suicide or something similar because you will die with him.
Also leaving a possessed body isn't as easy as leaving your own especially when in physical pain or emotionally compromised so it could leave you vulnerable to enemy attacks.
The story has been taken without consent; if you see it on Amazon, report the incident.
And then there's the difficulty of learning this Jutsu which makes it almost impossible to learn and if it wasn't for the very high talent both Kushina and Minato possessed as well as already being in a spiritual form.
It would have taken them waaay longer to learn it!
Minato still frowned a little while looking at the prisoners since he doesn't like to use such methods but he knew it was necessary and decided to just go with it because of the urgency of the situation.
"Okay, let's start" Said Minato as he nodded at Kushina and they both possessed the unconscious duo.
As they stood up with these two new bodies, they first tried to get used to them before they walked near Naruto and Minato said "Are you ready, Naruto?"
Naruto was feeling hesitant and looked at them weirdly because they were in different bodies, then he looked at me and when he saw me nod at him, he became determined and said "Um, I am ready".
"Good" Minato warmly patted him and under Kushina's worried look, he raised his right hand as each finger started glowing blue with chakra before he lifted Naruto's shirt and placed his hand on his abdomen, and soon markings started appearing on Naruto.
When the seal fully appeared on Naruto, Minato started rotating his hand clockwise and it felt as if he was opening a lock, and that's indeed what's happening as inside the seal space Kurama was looking as the paper that was hanging on the door imprisoning him quickly burned into ashes and a circular lock made of many connected sections appeared.
The lock slowly started opening one section at a time clock wise, the same direction Minato was turning his hand and Kurama's chakra quickly started leaving from it and trying to cover Naruto putting both Shisui and Fugaku on guard since they didn't feel safe around Kurama yet.
However, at this moment Minato simply gestured for Kushina and she quickly rushed beside Naruto and started helping him suppressing that chakra and not allow it to get in contact with his own to make the extraction process safer.
Kushina was perfect for this as she was the previous Jinchuriki of Kurama so she had experience in controlling some of Kurama's chakra.
'Some' is the best anyone could control before Naruto as the huge volume and Kurama's unwillingness to cooperate with people trying to use him never allowed for any of his Jinchuriki's to achieve anything with him.
More and More of Kurama's chakra started leaking from the seal even though he was trying his best to control it but it was still manageable for an Uzumaki like Kushina who is used to controlling her huge chakra reserves so she barely suppressed it until finally the seal was completely opened.
During this whole process, Naruto felt some pain but he did his best to endure it, but soon it became too much for him because once the seal was completely opened. Minato's
hand motion changed from a rotation to a pulling one causing Naruto to scream in pain but it went as quickly as it came.
The moment Minato used that pulling motion, Kurama felt a tug as if something was pulling at him and he quickly used his fastest speed to leave the space to not cause too much pain to Naruto and just like that; an almost 100 meters tall nine-tailed fox appeared in front of the group with Fugaku and Shisui quickly activating their Mangekyo Sharingan in preparations for the worst.
Something worth mentioning is that Minato never used the key to open the seal because he was the caster of this seal and doesn't need a key to open it.
"ROAAAAAAR" Kurama raised his head and roared at the sky in excitement, a roar that sent a huge shock wave through the air while his tails swayed around causing destruction everywhere they landed in the forest.
This is the might of the nine tails, a casual swing of one of his tails is enough to cause most ninja to despair and it indeed caused Fugaku and Shisui to worry even more.
"HAHAHAHAHA, I am finally free!" Said Kurama before he felt something hit him in the hand and heard someone yelling at him "Shut up you idiot can't you see Naruto's still in pain"
Kurama was about to lash out but he held it back after he saw Naruto in Kushina's arms frowning and unconscious, clearly still in pain. So he simply laid down while Shisui kept looking at him in awe 'So this is the nine tails! It's huge'.
Meanwhile seeing me hit Kurama; Fugaku almost had a heart attack but ended up heaving a sigh of relief when he saw how tame Kurama was.
'This kid will give a heart attack one day I know it' thought Fugaku while looking at me.
I looked at Naruto with my Sharingan and seeing that he was quickly going back to normal I heaved a sigh of relief before I turned my attention to this huge fox and smiled.
'Finally, I got a strong ally'.
