Meeting the Kyuubi

Meanwhile, deep within Mito's body, in the dark recesses of her consciousness, a pair of red eyes filled with malice snapped open, casting a crimson glow.

Chains shattered, and a torrent of bloody red chakra surged forth, accompanied by the menacing roar of a savage beast. Mito's expression contorted in agony as an evil and violent red chakra erupted from her body, forcibly ejecting Kirito and the others.

Above Mito's head, the red chakra coalesced into the form of a fierce fox head.

A chilling voice reverberated in Kirito and the others' ears, emanating from the ominous apparition. "Mito, these are the people you cherish the most. Just wait. Once I'm free, I'll slaughter them all. Hahaha~"

"Nine-Tails demon fox!"

Tsunade exclaimed with a grim expression upon seeing the fox head made of red chakra.

Though she wished to intervene, Tsunade realized she lacked the expertise necessary to tackle the situation.

Her proficiency in sealing techniques was lacking. Like Nawaki, she hadn't applied herself diligently in the past, and her ability to learn sealing techniques was still inadequate for this situation.

"Grandmother!" Nawaki noticed Mito's discomfort and, despite his own fear at the sudden appearance of malicious chakra, summoned multiple shadow clones using his strong willpower.

A series of impacts resounded as several clones rushed forward, only to be repelled by a shockwave when the fox head emitted a roar, dispersing Nawaki's shadow clones.

"Frustrating." He expressed his disappointment, ready to employ the multiple shadow clone technique again.

"Stop ! " However, Tsunade intervened, urging him to remain calm and avoid causing further trouble.

"But—"

Nawaki began to protest instinctively, but Tsunade's serious demeanor, coupled with Kirito's swift execution of hand seals, persuaded him to comply.

Kirito's rapid sealing actions drew the attention of the Kyuubi. Having remained within Mito's body, it was well aware of Kirito's proficiency, recognizing his preparations to confront its malevolence with powerful sealing techniques.

Having seized an opportunity to launch a sneak attack on Mito during her vulnerability, the Kyuubi was determined to thwart Kirito's attempt to nullify its escape.

"Brat, you should die ! " the Kyuubi bellowed, lunging toward Kirito with its jaws wide open.

Tsunade acted swiftly, employing a Chakra Scalpel to counter the Kyuubi chakra , but her efforts proved futile in halting its advance.

Similarly, the coming Momoka's attacks failed to hinder the Kyuubi's aggression.

Just as the Kyuubi poised to strike, Kushina intervened, emitting a massive golden chakra chain from her abdomen, pushing back the Kyuubi's chakra-formed fox head.

"Here we go," Nawaki exclaimed.

Thanks to Kushina's brief delay, Kirito successfully executed his meticulously prepared sealing technique.

In an instant, three azure chakra chains, adorned with numerous sealing techniques, emanated from Kirito, swiftly binding Mito, who was ensconced in the Kyuubi's chakra.

Sealing Technique: Titanium chain's !

Derived from the Uzumaki Clan's distinctive sealing technique, the Adamantine, this technique eliminated the prerequisite of an Uzumaki's physique, enabling its use by ordinary individuals. While it may have diminished the restraint on tailed beasts to some extent, it still presented an effective method of confinement.

In addition to the prerequisites, Kirito incorporated numerous binding sealing spells into the chakra chains, enhancing their restraining capabilities further.

As the blue chakra chains secured Mito, the Kyuubi's fox head emitted a reluctant roar. "No, no, no!"

With its final cry, the fox head dissipated into unconscious Kyuubi chakra, dispersing into the air. Simultaneously, the Kyuubi's chakra within Mito swiftly retracted into her body, restoring tranquility.

Subsequently, Mito opened her eyes, expressing gratitude toward Kirito before succumbing to unconsciousness once more.

"Grandmother!"

"Grandmother!"

"Mito-sama!"

Observing Mito's condition, Tsunade, Nawaki, and Momoka rushed forward to ensure her well-being. Their relief was palpable upon discovering Mito's unconsciousness was merely temporary.

"Kirito, Great job ! ," Tsunade reassured him with a smile, acknowledging his pivotal role in averting disaster.

Nonetheless, Tsunade couldn't shake the foreboding in her heart.

Her grandmother's condition was even more dire than she had anticipated, signaling the inevitable end of her life. Despite Mito's formidable abilities, the weakening of her seal's power reflected her deteriorating health. Otherwise, with Mito's expertise, the Kyuubi would have had no opportunity to cause trouble.

This incident would surely be relayed to their teacher.

Before long, their teacher might need to initiate the transfer of the Kyuubi.

There was no alternative; the Kyuubi's power was too immense.

In the absence of her grandfather, who could have effortlessly subdued the Kyuubi, Konoha lacked a formidable individual capable of restraining it.

Should the Kyuubi break free from its seal, its profound animosity toward Konoha would provoke a relentless onslaught.

At that juncture, even if the Kyuubi were resealed, Konoha would suffer catastrophic losses.

"Ah~"

In the end, Tsunade could only sigh inwardly.

As much as she wished to forestall her grandmother's passing, death was an inevitability. Regardless of her prowess in medical ninjutsu, she was powerless to alter this fact.

Upon hearing Tsunade's words, Kirito swiftly withdrew the chakra chains binding Mito.

However, at that moment, the Kyuubi's voice resounded in his mind. "Boy, I will remember you."

Kirito suddenly found himself enveloped in darkness, with water rising around him. A pair of colossal red eyes materialized in the gloom, fixing him with a murderous glare.

"Roar!!!"

A terrifying roar reverberated, accompanied by an overwhelming chakra impact. Kirito screamed before vanishing from the darkness.

In reality, Kirito awoke drenched in sweat, his complexion pallid.

"Is that the Kyuubi? Its power is truly formidable. Restraining even a fraction of its chakra is proving challenging. If it were to break free from Mito's body, I'd have no choice but to flee. With my current abilities, the titanium chains wouldn't suffice to contain its full power, not even one-tenth of it."

Kirito panted heavily, reflecting on the recent encounter. Although he had successfully bound the Kyuubi's chakra, the magnitude of its power had left an indelible impression.

With the chakra chains formed by the sealing chains against it, it was akin to restraining a behemoth with a thread. Such was the overwhelming might of the Kyuubi.

Fortunately, Kirito had faced only a fraction of the Kyuubi's chakra this time, enabling him to reseal it within Mito's body.

As the group of ninjas proficient in sealing techniques arrived and witnessed Kirito's successful suppression of the Nine-Tails, Momoka promptly exercised her authority as a Hokage advisor, instructing them to stand down for the time being.

"It's all right, return to your posts. I don't require your assistance at the moment," Momoka directed, easing their worry.

The leader, a Jonin from the Sarutobi clan, acknowledged the order promptly. "Understood. Should you need anything, do not hesitate to summon us. We'll be stationed outside," he assured before departing with his team.

However, a few sealing class ninjas remained, producing sealing scrolls to contain the residual Nine-Tails chakra lingering in the room.

Meanwhile, Kirito was actively engaged in the same task, his efficiency far surpassing that of the sealing class ninjas. Employing the chakra chains of the derivatives chains, he regrouped the intangible Nine-Tails chakra, swiftly drawing it toward himself.

Ultimately, Kirito gathered the dispersed Nine-Tails chakra into a bottle inscribed with numerous sealing techniques, then transferred it into an empty scroll.

Observing Kirito's actions, the sealing class ninjas eyed the chakra chains warily, recognizing their potency.

They were well-versed in the capabilities of this sealing technique.

Undoubtedly, it was an offensive sealing technique capable of restraining chakra and disrupting an opponent's ninjutsu by manipulating their chakra flow.

"Kirito-san, What time name of this ability ? "

Sealing Technique: Titanium sealing chains !

The name resonated in their minds as they noted the distinctiveness of Kirito's chakra chains.

Traditionally, the chains associated with the Uzumaki clan were golden, starkly contrasting with the ones currently employed by Kirito.

Evidently, these were a modified version, crafted through Kirito's innovation of the original one.

Moreover, Kirito, not hailing from the Uzumaki clan like themselves, demonstrated that they too could potentially master this enhanced sealing technique.

Impressed by Kirito's prowess as Master Mito's esteemed disciple, they recognized him as the most exceptional sealing art prodigy since Konoha's inception, having successfully refined even this formidable sealing technique.

"Kirito, is the sealing technique you're utilizing now a variation of the Adamantine chains?" one of the ninjas inquired, intrigued by Kirito's adaptation of the technique.

With a knowing smile, Kirito confirmed the ninja's assumption. "That's right, it's an improved version, and you can learn it without the blood of the Uzumaki family."

Anticipating the older ninja's intentions, Kirito calmly addressed the unspoken request before it was voiced.

"Then can you..."

Before the senior seal class ninja could articulate his true purpose, Kirito preempted him, nodding in affirmation. "No problem, I will announce this sealing technique later, and you can all learn it, but it requires two conditions. One is you cannot teach it privately; you must be initiated into the technique by me. And secondly, you must fully participate in the next Nine-Tails inheritance."

The older ninja from the sealing class readily agreed, without a moment's hesitation.

Kirito's conditions were lenient, yet practical. The first condition, requiring direct initiation by him, ensured the technique's controlled dissemination, preventing unauthorized spread. As for the second condition, participation in the Nine-Tails inheritance was essential for understanding the gravity of the technique and its significance in combating threats like the Nine-Tails.

As the older ninja of the sealing class agreed, the other ninjas of the sealing class also happily assented.

"Okay, I'm here to thank you on behalf of my teacher."

Seeing that the ninjas of the sealing class present all agreed to his conditions, Kirito said gratefully.

This thank you was genuine.

Only those who had faced Kyuubi directly knew its power. Once Kyuubi broke free from the seal, these ninjas from the sealing class who participated in sealing Kyuubi would be its primary targets and face a huge threat. One misstep could mean death.

These people had come here at great risk, and Kirito felt it was right to entrust them with this improved King Kong seal. If they could learn it, it would increase the safety of sealing Nine-Tails.

There is power in numbers.

The original plot did not delve into Kushina's success in becoming the Nine-Tails Jinchuriki, but after experiencing the power of Nine-Tails firsthand, Kirito realized that the process was no easy feat. This made sealing Nine-Tails even more daunting.

Although Konoha was not as weak as after World War Three, sealing the Nine-Tails would still be challenging.

Moreover, Mito's current condition was precarious, and her ability to aid in sealing Kyuubi was uncertain.

Hence, he needed more people to learn the sealing technique, which could effectively help trap Nine-Tails.

Kirito wasted no time, retrieving a scroll from another sealing scroll, and calling for the ninjas from the sealing class to teach them the improved version of adamantine chains.

The sealing class ninjas present were all elite practitioners, possessing solid foundational knowledge of sealing techniques. With Kirito's guidance, their learning progress would skyrocket.

However, Nawaki's sudden interruption interrupted Kirito's teaching. Rushing over, he addressed Kirito urgently. "Kirito, grandma is awake. She told you to come over."

Kirito immediately halted the teaching session and hastened to Mito's side.

"I'm here, teacher."

Kirito held Mito's hand tenderly and spoke softly.

"Kirito, you've done well. You've completed the last task. Now, you need to work harder to seal Kyuubi."

Mito patted Kirito's head affectionately with her free hand.

"Teacher, I just witnessed the power of Nine-Tails. With my current abilities, I fear I won't be able to subdue it."

Kirito voiced his concerns as he heard Mito's reassurance.

This was the truth. With his current strength, escaping from Nine-Tails might be manageable, but subduing it was another matter altogether.

"Don't worry. As long as I'm here, how far have you progressed with your Yin Seal cultivation?"

Mito's tone was calm and reassuring.

Though her physical condition was dire, she was determined to assist Kirito before her time was up.

"At my current rate of chakra accumulation, it will take about half a year to complete."

Kirito's response was honest.

He had commenced Yin Seal practice a year prior.

However, amassing chakra was a painstaking and time-consuming endeavor. Despite having a chakra replenishment "power bank" in the form of the zetsu clone, completion remained distant.

Moreover, his aim was loftier than that of Tsunade or Sakura.

To achieve the Immortal Mode and succeed in the blood fusion experiment, he needed the Yin Seal to create an extensive chakra reservoir within his body, maximizing his chakra control. Once completed, his Yin Seal would contain chakra comparable to that of a tailed beast.

"That voracious appetite of yours remains undiminished. No matter, before you depart, let me lend a hand."

Mito flicked Kirito's forehead playfully and smiled.

Before Kirito could protest, a surge of warm chakra flowed from Mito's hand into his body.

"Teache---"

"Quiet now, and accept it willingly."

Kirito was about to interject, but Mito's firm tone silenced him.

Gazing at Mito's familiar yet determined expression, Kirito's eyes welled with tears. He closed them briefly to suppress the emotion, then focused on accepting Mito's chakra. Channeling it into the chakra pool formed by his Yin Seal, he felt a gentle rain of blue chakra cascading into the pool, rapidly replenishing it.

After a while, a blue diamond-shaped mark manifested between Kirito's eyebrows.

Yin Seal : successful!
