"Bwahahaha! Good! Otherwise I would have to beat you up until you agreed like a good fox! Bwahahaha!" Kushina laughed loudly.
Kurama sweat dropped at her response, it's not everyday it is threatened by a child.
"Hold on! I think there is one key factor we are forgetting here, jinchuuriki die once the tailed beast is separated from them." Mito spoke up.
"Again, do you think I would even bring this up if I knew it would result in your death Mito? Come on, please have more faith in me." Kushina rolled her eyes.
"So what's your solution?" Mito ignored the fact she asked another stupid question.
"In normal instances you would be right, but you and many others underestimate the strong life force we Uzumaki have. Unless they are in the later stages of their age, Uzumaki can survive the extraction. We just need immediate medical attention so we don't end up dying from the massive loss of chakra in our vitals. Pure-blooded Uzumakis have a higher chance of survival than non-pure blooded Uzumakis. Senjus should also be able to survive, as for others who are not Senju or Uzumaki. They may have a much lesser chance of survival, but as long as they get immediate and proper medical attention, all jinchuurikis should be able to survive the extraction of a bijuu." Kushina explained.
It's rare, but the canon series of Naruto showed it is not impossible for jinchuuriki to survive a tailed beast extraction.
"I'm not even going to ask how you know this." Mito sighed.
"Yeah it would be a waste of time since I wouldn't tell you anyways. But since you've known me, have I lied to you once?" Kushina looked at Mito.
The older woman shook her head. "No, you haven't, I have no reason to doubt you now. Not that I did in the first place."
Kushina nodded with a grin. "Please release the seal, afterwards Kurama, do your part and no funny business. I better not sense a hint of hatred in your chakra." She warned.
Kurama snorted. "I'm not a fool, child. Petty revenge isn't worth my freedom from this unwarranted prison.
Kurama's words made Mito feel extremely guilty, this whole time she only saw the fox as an evil nuisance full of anger and hatred. A power meant to help Konoha against their enemies. Yet what right did humans have to use the tailed beasts as weapons? The answer is none, truthfully humans are no less dangerous than the tailed beasts they fear.
"I…I am sorry for my treatment of you. I had no right to seal you away for so long, at the time I only was thinking of helping my husband in his battle against Madara. I know my apology likely means nothing to you, but I still would like to apologize to you Kyuubi." Mito bowed sincerely to Kurama.
Kurama growled in anger. "I don't care for your apology Mito, your sudden change of heart doesn't change anything between us. You should be grateful to your granddaughter that I don't use this chance to seek revenge against you. It's already bad enough I can't get revenge against Hashirama or Madara!"
"Hate to burst your revenge fantasy, but even if you could you would still lose. Wood release and Mangekyo Sharingan can be used to subdue you, plus Mito can still seal you away again if necessary. Before you start talking a big game, get stronger first. You're a Sage, actually you should have a much higher resistance against genjutsu than you normally do when using senjutsu. How in the world do you get caught in Madara's genjutsu Kurama? I can understand the other tailed beasts since as far as I'm aware they aren't Sages, but you on the other hand…" Kushina was quite curious about this.
Kurama unexpectedly felt a rush of embarrassment well up in its chest. It looked away with a snarl on its face. "It takes time for even someone like myself to gather enough natural energy to empower myself. It also doesn't help that I was caught off guard, and we tailed beasts are naturally susceptible to Magekyo Sharingan or Rinnegan level genjutsu. I myself have a higher resistance to Mangekyo Sharingan level genjutsu compared to the other tailed beasts. Only someone with a powerful and skilled Mangekyo Sharingan user like Madara can affect me through genjutsu."
"Sounds like a bunch of excuses to me." Kushina teased.
Kurama growled in frustration. "Shut up! What I say is the truth!"
"Yeah that's true, still doesn't change that you're giving excuses. The great, powerful Nine-Tailed Demon Fox, most powerful out of the 9 tailed beasts by a huge margin, is weak against high-level genjutsu. How embarrassing for someone of your stature bwahahahaha!" Kushina pointed and laughed at Kurama.
"FOOLISH HUMAN CHILD! YOU DARE TO MOCK ME?!" Kurama erupted in strands of powerful tailed beast chakra.
"Awwww, is someone upset I spoke the truth? What a pitiful fox, all this strength and chakra and yet you find yourself at the mercy of ignorant humans. Madara had the balls to not only force you to help him in a battle against his rival that he could never beat. He even made you his personal summoning as if you were his pet! Truly a pitiful fox! Bwahahahahahaha!" Kushina continued to tease Kurama.
Kurama looked as if it was ready to bomb Kushina with a Tailed Beast Bomb.
Mito did not know how to react, she couldn't hardly believe how Kushina is blatantly mocking the Kyuubi in front of its face. Granted the seal is still in place, however knowing Kushina the way she did, the child will likely do the same while fighting the Kyuubi head on with a smile. "She's too crazy." She murmured to herself while shaking her head.
"Alright I'm done hehehe." Kushina wiped her eyes. "Mito, release the seal."
The older Uzumaki woman nodded, and within moments the seal started to unravel, releasing the Kyuubi from its cage.
Kurama said nothing but strode forward before stopping in front of the two women, holding out its fist towards Mito.
Mito was confused until Kushina spoke up. "Bump your fist against Kurama's, it will transfer its chakra to you this way. I'll handle the rest and seal the chakra in a separate seal for you to access it at will."
Her seal is not like Naruto's, it doesn't have a specific function to allow Kurama's chakra to be sealed in a separate space within her seal. Naruto possibly had the most unique seal of all jinchuuriki in history.
Mito followed Kushina's instruction, bumping her fist against Kurama's. She was shocked by the amount of chakra she can feel invading her chakra network. Never in her wildest dreams did she believe the Kyuubi had such pure and powerful chakra. It was as if she's being flooded with a massive influx of life force.
As this was going on, Kushina helped Mito direct all of Kurama's chakra into the new seal she just created. Kushina can create most of the seals to her knowledge within seconds.
At the same time, she was flooding Mito's cells with extremely potent life energy. This energy was essentially de-aging Mito and making her young again. Currently, Mito's body is covered in a golden aura as she focuses on accepting Kurama's full chakra.
Kurama was a bit surprised by Mito's change before ignoring it, its attention was more on how Kushina can control such pure life energy. The life force she generated far exceeded its own! It was absolutely mind-boggling to Kurama.
After some time, Kurama finally finished giving Mito all of its chakra. Not only was Kurama's body much thinner, it had to keep itself from falling into a deep sleep.
Kushina sent one of her Adamantine Sealing Chains from her body to touch Kurama. She wasted no time in replenishing its chakra with tailed beasts chakra.
"T-This is…h-how is this p-possible…?" Kurama was stunned, Kushina was giving it tailed beasts chakra. How can a human have tailed beast chakra without being a jinchuuriki?
Suddenly, Kurama found itself inside Kushina's sealed space. It looked around before seeing a giant, white ten-tailed version of itself sleeping. At least the white fox seems to be sleeping.
"I-Is this supposed to be me?" Kurama was even more lost.
"Pretty much." Kushina said as she suddenly appeared beside Kurama.
"Ten tails…you're a jinchuuriki? But I've never seen or heard of this particular tailed beasts before." Kurama asked.
"Technically I am indeed a jinchuuriki, but the fox you are looking at Kurama is more so my chakra than an actual tailed beast. See, I'm an Uzumaki and Otsutsuki. But my whole genetic makeup is weird, I was pretty much born a jinchuuriki of a ten-tailed beast that's different from the one you were a part of. As you can see my ten-tails is not only bigger in size but way more powerful with a much higher chakra capacity than the original Ten-Tails. It has no consciousness of its own unless I put my own consciousness into it. Different from Kaguya and the God Tree. By the way no one knows about this but you, I don't plan to show my tailed beast chakra until I'm in the war." Kushina explained.
Kurama didn't know what to say, honestly it is pretty terrified right now. If what Kushina says is true, then all of this is truly just her chakra. She has her own set of two different chakras within her. Human and Tailed Beast chakra born into one random Uzumaki and Otsutsuki hybrid?
"You said you were a pure-blooded Uzumaki…how in the world are you an Otsutsuki then?" Kurama was too confused and frightened at the same time.
"Honestly? I still have no idea. I just know I was born this way. The knowledge of me being an Otsutsuki was something I inherently knew, as if the knowledge was there since I began to grow conscious of my actions. Both of my parents are Uzumakis, I am a full-blooded Uzumaki and a full-blooded Otsutsuki. It won't come up like that on a blood test, however I know for a fact that's what I am." Kushina shrugged nonchalantly, she came to terms with her odd biology long ago. If anything she's grateful because of it, she's Kaguya with Whitebeard's powers.
There's no sense in mentioning her One Piece physique also being mixed since Kurama wouldn't fully understand what it means.
Her Haki can be passed off as a weird Otsutsuki ability.
"…..Brat, you have one messed up body…" Kurama said.
"Bwahahaha! Who are you telling?! But it's no use constantly dwelling on it. I was just born extremely lucky." Kushina laughed.
Kurama wasn't sure what to think anymore, all it wanted was its freedom and to get away from this insane human child.
Eventually they returned to Mito's sealed space as Kushina finished replenishing all of Kurama's chakra.
