[Naruto] Saga of Tanya the Kunoichi

'Yoru, proceed'.

Danzo, however, was overthinking it… he was too much of a cautious person and always assumed the worst scenario and had backup plans ready.

In reality, Minato wouldn't mind Danzo helping Tsuyu at all and even preferred it. Minato had observed Tsuyu all this time himself and seen that Tsuyu was capable of it - even if it was such a shocking sight. To begin with, he had intended for both Tsuyu and Naruto to use 9 tails chakra for the sake of Konoha and to fight the mysterious enemy of Konoha back then.

Yoru relayed the instruction from Danzo, from which Tsuyu continued. The outer seal was peeled off, revealing a spiral-patterned circular lock on the red gate. 

'To interact with chakra, you will have to use chakra. Let me guide you'. Yoru placed her hand on Tsuyu's back. Tsuyu felt most of her chakra was mobilised in herself, creating an apparition of her image.

Already feeling the way it was created, Tsuyu didn't need Yoru to guide her anymore.

'Now send your chakra through the gap in the seal to connect it with Kyubi's. You then can take away his chakra as allowed by the gap. However, just as you can take his, he can take yours through the connection. Immediately retreat and cut the connection if you cannot withstand its will and hatred'.

Tsuyu understood and proceeded. Her apparition passed through the gap in the seal and latched onto the Kyubi, who couldn't do anything about it since he was inside the seal. 

Now, Kyubi had originally intended to give her his chakra to weaken the seal. But due to a spectator, it would be too shameful for him to look so willing. Therefore, he resisted as much as he could because of his pride.

As the connection was made, Tsuyu felt a tugging pulling her chakra. But Tsuyu's will was stronger, and Kyubi couldn't syphon her off. 

She looked at Kyubi with a cold glare. All this time, Kyubi had been cursing by the way, but everyone pretended he was talking to air.

"Kyubi-san; I apologise for my intrusion, but I hope we can cooperate to make it easier for both of us".

'HAH?! YOU DARE ASK FOR MY COOPERATION? I KNEW IT! YOU TOO ARE LIKE OTHER HUMANS. GREEDY FOR MY POWER! ONLY SEEING ME AS A WEAPON FOR USE!'. 

"While I do admit I am trying to harness your power, I have never seen you as a weapon. I see you as any other person. Every human relationship was based on giving and taking. And you have something I may need in the future. I apologise for not having your permission, but I acknowledge I am merely borrowing. I owe you for using your power. I promise I will pay you back in the future once I can give you what you need, Kyubi".

Tsuyu was honest about this, but she clearly stated that 'if she can', she would. But she couldn't right now.

Kyubi wanted freedom the most. But letting him free means her death. And even if she can just live well; Kyubi was a part of Konoha's 'property', and it was not up to her. 

If anything, she could consider it once she reached the top and see if it was possible to have an alternative that give everyone their benefits like having Kyubi living freely within the boundary of Konoha or its perimeter like some sort of Guardian Beast or something and reach an agreement. Kyubi would also gain the protection of Konoha from other enemy villages. If Kyubi escaped now, Konoha would just dispatch a team to catch him. Even if he can escape from Konoha, the other Nations would try to get him. Kyubi then would have to live in hiding and constantly have to fight - what kind of freedom was this? Kyubi did not seem to understand this and never saw the long term solution - Tanya sighed inwardly.

'YOU LIAR! YOU-', Tsuyu ignored Kyubi's complaints and started to siphon Kyubi's chakra. A small stream of red chakra flowed through the seal and into Tsuyu's body. The dark red viscous chakra starts to mix with hers.

I hate you! I will kill you! It's painful! Please stop!

The voices and emotions crept up to Tsuyu's mind. Her left eye turned into a demonic pupil with a red iris on the dark black sclera. She can feel the hatred and anger contained in such power trying to consumed her mind. 

Alas, Tsuyu's willpower was far stronger. She couldn't push the hatred completely out of her mind, but her rationality still won over the feelings. Some shitty being had forced her to feel 'faith' before but it's her mind that never let her bow down to that shitty being. This was nothing at all. If Tsuyu had to equate it, it was akin to feeling starved but refusing to eat.

Danzo saw evil red chakra inside Tsuyu's chakra network through his sharingan. The chakra leaks out, forming a layer of translucent bubbly red chakra cloak around Tsuyu's body.

'Vital signs within safe limit. Cellular activity improved by…', the Root member monitoring Tsuyu's body keep checking the devices and readings the data to Danzo.

'Increase absorption by half a point'. Danzo ordered.

Tsuyu received the order from Yoru and did as told. The data were observed and recorded as the test was ongoing.

Tsuyu eventually reached 3 tails state. Her chakra was so massive it caused constant pressure outward from her body; the deep, dark translucent chakra cloak caused scorching heat in and out of Tsuyu's body, but she endured. 

But now it was the seal that prevented her from taking any more chakra unless 

Kyubi willingly poured it out as well, or if the seal gap widened for more chakra to pass.

'Danzo-sama. The hard limit has already been reached. No more Kyubi chakra can pass through the gap of the seal', Yoru pointed out.

Meanwhile, the Root member monitoring Tsuyu's body kept muttering her data.

'Cellular activity reached above its functional limit. Her body tissue was receiving constant damage and repair… but overall her tissues received more damage'.

Danzo listened with focus to the report on Tsuyu's body condition while observing carefully with his Sharingan. He figured Tsuyu's chakra was unable to completely suppress Kyubi's, which was volatile, and they were fighting each other like fire fighting water—they were forcefully mixed like water and oil in a shaker. 

The shaker in question would be Tsuyu's mind and body, and this took a toll on her, causing damage to her tissues, chakra loss, and overall major performance waste with incompatibility between the two chakra's fighting to separate or consume, and even reduced Tsuyu's 'lifeforce' through the continuously regeneration and destruction of body cells.

'Maintain the form as long as possible. Terminate if Tsuyu is unable to handle it anymore. We have to know her limit'.

Yoru passed the order, and Tsuyu followed. Kyubi screams were like atmosphering noise. Yoru constantly monitors Tsuyu's spiritual fluctuation to estimate her spiritual energy.

After 23 minutes, Tsuyu's body cannot take the toll anymore. Her sitting posture slanted from losing strength to carry itself.

The connection between her consciousness and Kyubi's was cut off, causing Tsuyu to return to her body.

Tsuyu winced in pain and soreness all over her body. As if her entire body had just gone through 6 hours of continuous sprinting. She couldn't move a single muscle now. But her mind and will were still good, albeit a little tired, but nothing compared to her body condition. Yoru helped Tsuyu to stand.

'Give Tsuyu a thorough checkup. I want the result as soon as possible'. Danzo ordered his men.

Danzo reads the data and can come to conclude that Tsuyu had extremely uneven high spiritual energy, or rather Yin part, compared to her physical energy, the Yang part. Despite being of Uzumaki lineage, it was not enough, somehow. Danzo theorized it's due to the Yin half constantly supplying mostly Yin chakra overall.

On the other hand, in theory, Naruto would instead have had more Yang chakra and rigorous physical energy and body compared to Tsuyu. That also explains why Naruto was seemingly untalented in chakra manipulation due to the uneven ratio between the amount of spiritual energy and the physical energy.

Now that Danzo figured out what was wrong with Naruto; it also meant Naruto had certain advantages. Just like Tsuyu's chakra manipulation and mastery comes from her high spiritual energy. Naruto would then have high vitality, endurance, and anything physical.

In theory, Naruto should be able to master 8 Gates even better than Might Guy and become an even better Taijutsu specialist. He can also use forbidden techniques that take a toll on the body of the user. Danzo made a note on his mind in case he had a chance to bring Naruto as well to his side.

As for Tsuyu, she was almost a hexagonal soldier. If only her body was on par with her spirit, she would be a true demon. Danzo was certain Tsuyu would not be able to handle all of 9 tails chakra for now.

To fully control the 9-tails power, she would need to improve her physical condition and therefore increase her chakra potency and true volume to overcome 9 tail's. That requires physical training and time for Tsuyu's body to grow to become an adult.

But that would be slow… 

Danzo may be patient, but he was too old now. He wanted results faster.

As for other methods to boost her physical body, Danzo could not think of any method that did not have any side effects. Hashirama cells were a perfect solution if and only if Tsuyu could take it, but a mistake would cost Tsuyu her life. He couldn't take the gamble.

As for alternative solutions, natural energy can strengthen her overall chakra as senjutsu chakra and allow more control over Kyubi as well.

Danzo made his decisions and plans. 

First, he needed the Key for Tsuyu's seal for the future eventual event. Jiraiya would know where it was. And knowing him, there was a high chance he would agree since Tsuyu was his student's daughter. 

Second, Tsuyu can learn Senjutsu from Jiraiya. Minato was able to learn Senjutsu, although it was unfortunate he did not manage to master it before his eventual death. It's reasonable for Tsuyu to be able to do it with her talents and genetics.

Thirdly, as a temporary measure, he could give Tsuyu one of the forbidden regeneration techniques to repair her physical body and allow extended usage of Kyubi chakra. This would further shorten her lifespan. But in a battle, a day of life was worth nothing compared to dying in that moment.

As for bodily modification, he knew of one capable person. Naturally, it was Orochimaru. The last contact he made with Orochimaru was to help him establish his place in Otogakure after his defection.

While their cooperation was stopped after that, they were never personal enemies. It was still possible. Danzo, at this point, did not believe Orochimaru would harm Konoha. Perhaps revenge towards Hiruzen, but if that was only it, then Danzo was more than willing to give a helping hand to get rid of that old man. After all, he knew Orochimaru would be more occupied with his desire and thirst for knowledge compared to revenge and sentiment.

Danzo decided to write a letter and send it to Orochimaru through Akatsuki. Akatsuki was easily reachable, given they were a mercenary organisation; this would be no problem. As for what he was willing to trade. He had money to fund his experiments. That would be enough, certainly.

Though… Danzo wouldn't expect that letting Orochimaru see Tsuyu was akin to offering the forbidden fruit to the snake himself…
