Thanks to the Moon I transformed into my Oozaru form first to distract the Kyubi and to test its power. I fired a Ki blast from my mouth at Kurama but he dodged it. Feeling that I was a threat, Kurama started charging a bijudama, at the same time I teleported right in front of him and shut his mouth up as he discharged the blast into his stomach. Kurama spat out blood as it was gravely hurt and simply fired smaller versions of the bijudama at me. I couldn"t dodge them all in my current form so I had to mostly block them with my arms. Little wounds were present on my arms and body. I threw a few boulders and trees at him to get Kurama to move towards Kushinas" direction. Angry at my persistence, Kurama tried firing another charged Bijudama. I wanted to try my power against the attack with my own. I put my hands together in Son Goku"s signature move.
Oozaru Sage: KME, HME, HAAAAAA!!!!!
A gigantic flash of light was all that could be seen by those looking in but to me, in this form, made my blood boil. My Kamehameha was still fighting it out with Kurama"s Bijudama. I yelled and put more power into my blast and started to push the Bijudama towards Kurama. The energy fight ended, the landscape drastically changed and Kurama was blasted back as he was on the ground losing blood and his chakra started dissipating rapidly. I grabbed Kurama by it"s scruff but was immediately attacked. Kurama bit me on the forearm. I yelled, gritted my teeth and I quickly uppercut Kurama in the jaw and gave him a few jabs with my other arm for good measure. I finally knocked out Kurama and dragged him to Kushina. Luckily for me Minato also repelled Obito away. Scared out of his mind from being in the presence of my Oozaru form, Minato covered Kushina. I condensed my form into a True Saiyan to keep watch over Minato while he performs the seal.
Sage: Nii-chan, stay your weapon, keep calm and re-seal half the Kyubi back into Nee-chan and the other into Naruto.
Minato, hearing my familiar voice came back to his senses, while still trembling.
Minato: Sage-kun is that really you?
Sage: Now is not the time to be asking me this Nii-chan.
Minato:(Nodded in agreement) But why seal half into both?
Sage: Nee-chan lost too much vitality, the whole Kyubi can hurt her further so by splitting it you can also minimize the damage and keep her alive.
Minato used the Eight Trigrams Sealing technique on Kushina and Naruto. By the end of the night, Konoha had 2 Jinchuriki, kept their 4th Hokage and a monster that appeared out of nowhere. I returned to my normal state. Looked at the conditions of Kushina and Naruto before I teleported to my parents location with the last bit of my strength.
Satsuki: Sage!!! Where were you? Why are you hurt?
My mother held me tight as I started to lose consciousness. My father ran up to confirm how I was and that was the last thing I remember from that night.
