Naruto: One Eye Tenseigan

Tomaru's journey to the Fire Temple had yielded satisfactory results—beyond expectations, even. Not only had he secured the potent energy of Kyuubi's chakra from Sora, but he also claimed the refined essence of Chiriku's chakra.

Tomaru is interested in Chiriku chakra. Chiriku's chakra resonated with a peculiar harmony—a blend of intense spiritual discipline and raw power, shaped through years of meditative refinement. It was no ordinary energy. The monks of the Fire Temple had honed it over centuries, enabling techniques that balanced spirituality and destruction.

Tomaru had previously absorbed Haku's chakra.

In this world, chakra functions not only as a source of energy but also as a sophisticated repository of genetic, elemental, and spiritual information. The absorption of an individual's chakra involves a profound interaction with this intricate data, encompassing:

Jutsu Blueprint: Chakra encodes the intricate instructions for jutsu formation, detailing the synthesis of elemental affinities and individualized control methods.

Energy Code: Chakra manifests unique energetic patterns reflecting elemental affinities and manipulation techniques.

Haku's chakra, in particular, encapsulated the genetic framework for his Kekkei Genkai, Ice Release (Hyōton), an advanced elemental technique inherited through specific bloodlines. This Kekkei Genkai facilitated the flawless integration of water and wind elements, producing true Ice Release.

Haku's unique genetic composition allowed him to combine water and wind elements with exceptional precision. To create Ice Release, Haku utilized raw chakra, channeling it through the water element as the physical foundation. The wind element was then infused to rapidly freeze the water into ice while maintaining its structural stability and durability. This process was seamlessly facilitated by Haku's Kekkei Genkai, which enabled the natural and efficient merging of these two elements into a cohesive and powerful technique.

The resulting ice, infused with chakra, exhibited extraordinary properties: enhanced strength, resistance to heat, and durability beyond ordinary ice. These attributes rendered it immune to conventional melting and adaptable for diverse applications.

Ordinary ninjas, lacking the Hyōton bloodline, could not replicate true Ice Release. While a Suiton user might freeze water with a wind-based jutsu, the result would be ordinary ice, devoid of Hyōton's flexibility, durability, or heat resistance. 

The strength and sophistication of Ice Release are intrinsically tied to the user's chakra reserves and their ability to control chakra with precision.

When a user possesses greater chakra reserves, they can channel more energy into their Ice Release techniques, resulting in the creation of larger and more durable structures. These ice constructs are not only capable of withstanding extreme heat and high-impact physical attacks but also retain their integrity in intense combat scenarios. With sufficient chakra, a user can create towering barriers, sprawling fortresses, or vast landscapes of ice, each imbued with extraordinary resilience and endurance. The scale and strength of these creations directly correlate to the amount of chakra infused, making chakra reserves a critical factor in determining the overall effectiveness of Ice Release.

The finesse of a user's chakra control plays an equally vital role in the application of Ice Release. Advanced chakra manipulation allows the formation of intricate and versatile ice structures. For example, skilled users can produce ice that moves fluidly, mimicking the flexibility of water, while maintaining the durability of solid steel. This flexibility is invaluable in combat, enabling the ice to adapt to dynamic situations and shift forms as needed. Additionally, high levels of chakra control grant the ability to create ice that is impervious to environmental melting, ensuring its stability even in extreme conditions. Such ice can take on unique properties, from enhanced malleability to heightened resistance, further expanding its utility.

The act of chakra absorption involves more than mere energy assimilation; it constitutes access to a vault of encoded data, including jutsu blueprints, elemental compositions, and even the will of the original user. Despite possessing the Tenseigan, which endowed him with formidable chakra absorption capabilities, Tomaru faced limitations:

The Tenseigan could not interpret or replicate jutsu encoded within absorbed chakra.

Unlike the adaptive bodies of the Ōtsutsuki, Tomaru's human physiology restricted his capacity to integrate foreign chakra seamlessly.

In contrast, the Ōtsutsuki Clan exemplified an evolutionary leap in chakra manipulation, transforming absorbed energy into a component of their essence. This unique adaptability circumvented the limitations faced by ordinary ninjas.

Tomaru's incorporation of White Zetsu's cells granted him access to its unparalleled copying abilities. White Zetsu's biological nature allowed for replication of jutsu by absorbing chakra, extracting its encoded information, and interpreting the will embedded within. Upon absorbing chakra, White Zetsu could:

Decode the user's chakra patterns, elemental affinities, and jutsu blueprints.

Integrate this information into its own systems for precise replication.

Seated in meditative stillness beneath the expanse of the night sky, Tomaru's Tenseigan emitted a subdued luminescence as he focused intently on the foreign energy permeating his being. Chiriku's chakra presented itself as a disciplined and refined construct, shaped by a lifetime of ascetic devotion and rigorous spiritual practice. Unlike the volatile ferocity of the Kyuubi's chakra or the precise lethality of Haku's, Chiriku's energy was imbued with an intrinsic serenity, resonating with the doctrinal ethos of the Fire Temple: balance, spiritual fortitude, and unwavering resolve.

Encoded within this chakra lay the blueprint for the Fire Temple's ultimate technique, Welcoming Approach: Thousand-Armed Murder. This powerful ability relies on mastering the Gift of the Hermit Group chakra, a special energy developed through constant training by the ninja monks of the Fire Temple. This chakra is essential for both performing the technique and unlocking the Sealed Iron Wall to access the Fire Temple.

Tomaru adjusted the flow of this newfound energy within his system. The White Zetsu cells now integrated into his physiology acted as an advanced conduit, deciphering the intricate layers embedded within Chiriku's chakra and translating its latent data into actionable insights. He closed his eyes, allowing his own chakra to harmonize with Chiriku's, creating a synergistic interplay between the two distinct energies.

As the integration deepened, a vast repository of encoded knowledge became accessible to him. Unlike elemental chakra manipulations such as Fire Release or Water Release, the Fire Temple's techniques emphasized profound spiritual modulation, underscoring the importance of intent and the practitioner's internal equilibrium.

Chakra stored specific "instructions" for performing a technique, including the flow, control, and molding of chakra necessary to execute it. The Welcoming Approach: Thousand-Armed Murder was no exception—its intricacies were encoded in Chiriku's chakra. Yet, it was more than a mere technique; it was a manifestation of spiritual energy, requiring the summoning of a spectral construct that embodied the practitioner's spiritual strength and discipline.

The Thousand-Armed Kannon Spirit wasn't conjured through brute force or raw chakra reserves. Instead, it required an intricate weaving of spiritual intent and chakra flow, guided by the user's will. Embedded within Chiriku's chakra was not just the methodology, but also the will of its original owner. Chiriku's chakra carried a quiet yet unshakable resolve, the byproduct of his years as a guardian of the Fire Temple and his spiritual devotion. This resolve served as the final key, a bridge between technical mastery and spiritual embodiment.

Tomaru began to manipulate the flow of chakra, feeling the beginnings of the Kannon Spirit taking shape. A faint golden aura surrounded him, illuminating the clearing with a soft, ethereal glow. Then, with a flash of light, the Thousand-Armed Kannon Spirit materialized. Its form was ethereal yet imposing—a massive, serene figure with an otherworldly calm radiating from its every movement. Its translucent arms shimmered like liquid gold, extending into the night sky.

Tomaru's eyes widened slightly as he took in the sight. Despite his calm exterior, he felt a flicker of awe. The spirit's sheer presence distorted the air around him, its tranquil visage masking the immense power it harbored. It was a testament to Chiriku's legacy and the culmination of the Fire Temple's teachings.

But admiration quickly turned to focus as Tomaru began testing his control. He moved one arm. Then another. The spirit obeyed, its movements smooth and precise. Encouraged, Tomaru tried to move more arms. Ten. Twenty. Fifty. The strain began to build, and he felt his chakra reserves depleting at an alarming rate.

By the time he reached over a hundred arms, sweat poured down his face, and his breathing grew labored. His chakra reserves, twelve times that of an average jonin, were formidable. But even they paled in comparison to the demands of the Thousand-Armed Kannon. Chiriku's chakra was a necessary component, acting as the catalyst for the technique, but the burden of maintaining it fell squarely on Tomaru's own reserves.

As the spirit began to fade, Tomaru let out a deep breath. The night air was cool against his skin, but his body burned with exhaustion. The Thousand-Armed Kannon had not been fully realized, but this attempt had been a success in its own right. He had taken the first step in mastering one of the Fire Temple's most sacred techniques.

Tomaru also intended to experiment with the formidable Kyuubi chakra, but exhaustion weighed heavily on him. His chakra reserves had diminished by more than half. This was the first time he had pushed himself to such an extent.

Tomaru's natural chakra reserves, already twelve times those of an average jonin. Yet, the Kyuubi chakra he had recently acquired dwarfed his own reserves, its magnitude approximately 70% greater than his own reserves—a precise yet humbling contrast that underscored the formidable nature of the Kyuubi's energy. Remarkably, this was only a fragment of the Kyuubi's true chakra—merely the portion that had been sealed within Sora's body. Tomaru couldn't fathom the full extent of Kurama's energy, and the thought alone served as a humbling reminder of the immense forces that existed in this world.

Managing this immense power was made possible only through the Tenseigan—a divine ocular ability that granted unparalleled mastery over chakra. The Tenseigan's precise control allowed Tomaru to regulate the chaotic storm of Kyuubi chakra with a deftness that few could achieve. Without it, he might have succumbed to the overwhelming hatred and corrosive negativity imbued within the chakra, as these emotions were an intrinsic part of the Kyuubi's essence.

The legacy of the Kyuubi, one of the nine Tailed Beasts, was steeped in conflict and tragedy. Its chakra was both a blessing and a curse, capable of bestowing immense power while eroding the will of those who failed to harness it.

As he sat beneath the starlit sky, Tomaru recalled Uzumaki Naruto, the Seventh Hokage, who had forged a unique bond with the Kyuubi, known as Kurama. Unlike Tomaru, Naruto had achieved harmony with the beast through empathy and trust, transforming a relationship of animosity into one of mutual respect. This union had unlocked unprecedented strength, allowing Naruto to shape the course of history and bring an end to the Fourth Great Ninja War.

Imagining the colossal scale of Kurama's full chakra brought Tomaru back down to earth. Lately, he had indulged in a sense of superiority after defeating formidable opponents like Chiriku and Zabuza. However, the concept of "Shinobi God"—a term used to describe power levels akin to that of Hashirama Senju—reminded him of his current limitations. Hashirama's mastery over chakra, wood release, and the ability to suppress Tailed Beasts stood as a benchmark that Tomaru was far from reaching.

This reflection also brought Nagato to mind, a looming threat in the shadows. Wielding Madara's Rinnegan, Nagato was perhaps the strongest ninja alive, commanding devastating abilities like the Six Paths of Pain. The prospect of confronting such a foe underscored the gap between Tomaru's current strength and the pinnacle of shinobi power.

The realization tempered Tomaru's ambitions with humility. He recognized that while his progress was commendable, the path to true mastery would be long and arduous.

In the quiet of the night, he closed his eyes and reached inward, not just for chakra, but for the resolve to face the trials ahead.
