Enso naturally absorbed Toba's soul for himself. After all, it would be better than leaving his father in that Endless Void. From his father's memories, he learn of another surprising secret.
Toba Senju was no ordinary Shinobi, as he was the son of Tobirama Senju. No wonder, his Chakra Pool easily matches a pure blood Uzumaki. He always lived under his father's shadow after Tobirama became the Second Hokage. All his hard-earned strength and accomplishments were credited to his father, as people were unaware of the relentless training he had undergone.
Tobirama naturally taught Toba all his signature techniques, except for Flying Raijin and Edo Tensei. The main reason is that Toba Senju's talent is lacking in sealing Jutsu, and forbidden Jutsu is naturally out of question.
His father's relationship with his grandfather is very fragile. It reaches the point that his father decides to leave Konoha and become a rogue Ninja. All their free time was spent on training in Shinobi Art. Tobirama was always frustrated with his son, as he felt the urgency to push him beyond the limit. He never praises him, and keeps drilling him to become stronger.
The stern and hard personality of Tobirama causes the rift between the father and son to open wide, as time passes. Enso can only sigh after looking through his father's memories. Too bad, they could never spend time together in this lifetime.
A profound calmness washed over Enso as he lay in his mother's gentle embrace. His golden eyes blinked open, taking in the world around him in ways he had never known. It was a peaceful moment, starkly contrasting the eternal chaos that had once consumed him.
Here, in this quiet home by the sea, a strange serenity settled within him—a deep stillness that seemed to radiate from every corner of the room.
His tiny body pulsed with life as his gaze drifted upward to the soft, earthy ceiling of their humble home. The fading sunlight filtered through the wooden beams, casting long shadows on the floor and bathing the room in a warm, golden glow.
As his senses expanded, Enso felt the warmth of his mother's embrace, her love radiating through every touch. Enya's presence was as solid and nurturing as the earth beneath them, yet it carried a quiet sorrow for the absence of Toba, the man she had once loved. The weight of his absence lingered in the air, but Enya's unwavering determination to raise her son alone, to protect him and honour Toba's memory.
Her voice was soft, cooing with comfort in her tone, transcending words. The rhythm of her voice soothed him, and her fingers—gentle as the breeze—stroked his soft, infant head. As she did, something stirred deep within him. Her care and love for him reminded him of his parents from his previous lifetimes. Unknowingly, he began to accept his new identity.
Three years had passed since Toba Senju's death. Enso, now five years old, had grown wise beyond his years. He helped his mother with the daily chores of their humble household, learning quickly and absorbing every lesson that came his way.
Enya, though often busy with the medical clinic, found time to teach her son. Together, they maintained a quiet life, far removed from the chaos of the Shinobi world, and Enso was grateful for it. Yet, even at his young age, he knew he could not remain in this peaceful cocoon forever.
Every day, Enso pushed his limits. He ran for miles, strengthening his stamina, building his muscles. His body was already powerful, but without proper conditioning, the energy within him would overwhelm him. Pain became a familiar companion, yet Enso endured it, stretching his limits further each time, driven by the belief that his potential was limitless.
His training routine was simple but demanding—push-ups, sit-ups, pull-ups—testing his endurance and physical strength. Yet Enso constantly broke his records, even at just five years old. Thanks to the endurance of the Doctor, Enso learned to stretch his pain threshold, pushing himself beyond his limits.
But strength wasn't all he focused on. Flexibility was just as crucial. Enso's inherited acrobatic knowledge, combined with the strength running through him, made him a rare child—one whose body, though still young, displayed a level of mastery over itself that few could match.
Enso's training began with an understanding of his body—a realisation that the vast strength pulsing within him wasn't just raw power to be unleashed, but a force that needed to be refined, controlled, and harnessed. Enso would need to build the right kind of muscles—each one tailored to support a different aspect of his strength.
The first step in his journey was understanding muscle anatomy, a concept Enya had taught him with a combination of simple lessons and hands-on training. Enso would begin by focusing on the development of his pink fibres—also known as fast-twitch fibres—those responsible for explosive power and rapid movements.
In the early days, Enso spent hours practising fast, powerful movements—kicks, jabs, and rapid footwork. He pushed his body to its limit with explosive sprinting drills, quick jumps, and sudden direction changes. His muscles burned with the effort, but each burst of effort was a deliberate test of his ability to command speed and agility, building the pink fibres in his legs, arms, and core. As he focused on refining his technique and enhancing his explosiveness, his body adapted. His pink muscle grew denser and more refined, allowing him to execute strikes and movements with startling speed.
Each powerful kick and jab sent a thrill through Enso's body, and with each new movement, he felt his muscles stretch and awaken. It wasn't just physical pain he endured; it was a thrilling discovery of what his body could accomplish.
But speed alone wouldn't be enough. Enso knew that raw power needed endurance to fuel it. For that, he would turn his focus to red muscle fibres, those responsible for sustained, continuous effort. The red fibres were all about endurance, helping the body perform without tiring quickly. These fibres were important for the long-term stamina Enso would need, especially as he moved closer to unlocking more of his vast potential.
To target his red muscle, Enso practised gruelling training sessions that required sustained effort—long-distance running, climbing trees, carrying heavy weights, and doing sets of low-repetition but high-duration movements. He would push through hours of this kind of training without resting, driving his muscles to work with sustained power.
Enso's body slowly became more conditioned to these red fibres, giving him a strong, continuous foundation that kept his body from giving out when tapping into his raw strength. This stage of training also built his ability to recover quickly from exertion, preparing him for longer, harder battles that would eventually come.
Yet, despite this newfound endurance, Enso could still feel the weight of his power straining his body. He needed to develop a third type of muscle—a type that could provide explosive bursts of force when required. This was where white muscle fibres—the slow-twitch fibres—came in. These fibres were dense, thick, and more resistant to fatigue, capable of producing immense power over extended periods. While Enso's body could now exert controlled bursts of strength and power, his ability to access sustained raw power was still lacking. He needed to strengthen these white fibres to handle the deeper, more powerful levels of force.
For the white muscle, Enso would train with strength-focused exercises. He worked with heavier weights, focused on slow, controlled lifts, and performed resistance training designed to build the explosive power required for his later forms of combat. Every movement became deliberate, an effort to unlock the deepest well of power within his body. These white muscles would form the foundation of his raw might—the reserve he could tap into when he needed sheer strength to overcome his limitations.
As the months passed, Enso's body adapted in ways he hadn't expected. The pink fibres gave him the quickness of a snake, allowing him to deliver fast strikes and evade incoming attacks. The red fibres granted him the endurance of a wild stallion, allowing him to run for miles or hold a position for hours without tiring. The white fibres, still in the early stages of their development, slowly began to bulk up, making his raw strength feel almost limitless.
But it wasn't just the individual fibres that made him so formidable—it was how these three muscle types worked together in perfect harmony. Enso's muscles didn't just function in isolation; they complemented each other, each type supporting the others.
When Enso moved, the pink fibres would initiate the motion, the red fibres would sustain it, and the white fibres would provide the deep power needed for an impact or defensive movement. As each fibre worked in conjunction with the others, Enso's body became a finely tuned machine, one capable of handling the strain of his enormous potential.
As the seasons passed and the years slipped by unnoticed, Enso grew. Though the days were simple and quiet, a restless energy stirred within him, one he couldn't yet explain. The gentle hum of his early life began to transform, and the world outside called to him more insistently than ever.
By the time Enso reached his fifth birthday, he had learned to tap into approximately 5% of his total physical strength. Each movement, whether a strike, a dodge, or an evasion, was a testament to the deep training and mastery of muscle fibres working in unison.
Enso still had much to learn, and his strength was only a shadow of what it would one day become. It was a long process, one that would require patience, perseverance, and dedication. But every day he trained, Enso knew he was one step closer to unlocking the true depth of his potential.
Enya, watching her son's relentless training, felt a mix of awe and concern. He was still just a child, yet the intensity with which he trained surpassed that of even the most seasoned adults. His determination was inspiring, but it also broke her heart. Each time he reached his physical limit, Enya used her Mystical Palm technique to heal him, easing the strain in his muscles so he could continue.
Enso's curiosity about the Shinobi world finally emerged. Though Enya had hoped to delay this moment, she saw the quiet resolve in his eyes and knew it was inevitable.
"Mother, teach me about chakra control," Enso asked, his golden eyes filled with determination. "Teach me the ways of the Shinobi."
Enya hesitated. She had kept Enso far from the dangers of the shinobi world for so long, but she knew his potential. He had already demonstrated remarkable chakra control, even without formal training.
"We must leave the Land of Waves," she said. "This village is too far removed from the shinobi world. We cannot risk drawing attention."
Enso understood her reluctance, but his resolve did not waver. He demonstrated his growing mastery over chakra, using Mystical Palm with ease, leaving Enya in awe. Realising the inevitability of his path, she decided they would go.
They would journey to the Hidden Leaf Village. The decision was bittersweet. They had lived in the Land of Waves for five peaceful years, building relationships and establishing themselves in the community. But Enso's future was calling, and there was no turning back.
Over the next month, they prepared for their journey. Enya taught Enso the basics of Fuinjutsu, sealing their belongings into scrolls to make the journey more efficient and inconspicuous. When the day of departure arrived, they were ready. They sealed everything they could into scrolls, leaving only the essentials.
Their journey took three months. During this time, Enya continued to teach Enso chakra control. He quickly surpassed her, mastering techniques like tree climbing, leaf concentration and water walking exercise.
Enso was so talented that he could maintain 6 Leafs while tree climbing and water walking. By the time they reached the Hidden Leaf Village, Enso's chakra control had exceeded most adults, including Enya herself.
It would take less time if they were to focus on travelling, but Enya makes use of the environment and drills the basic training into her child. Enso had already watched his father's memories, so his understanding of the foundation techniques is pretty solid. He learn everything so quickly that he would try to increase the difficulty to train, challenging himself to the extreme.
She had witnessed his relentless discipline firsthand: the tireless physical drills, the razor-sharp focus in chakra control. Back in the Land of Waves, her work at the clinic kept her too busy to truly notice how seriously Enso trained. But now, with nothing to distract her, she saw everything.
The strange exercises he performed along the way—many of which would push even a trained Jōnin to their limit—he completed with unsettling ease. It made her realise just how far he'd already come. Come to think of it, she'd never seen a five-year-old with a shredded physique before. Not like this.
It was almost painful to watch. Enso had a habit of driving himself to the edge of exhaustion—pushing through his physical limits until he collapsed. Then, with the calmness of a practised medic, he'd heal his own body using the Mystical Palm Technique to ease muscle fatigue... and begin again.
What kind of five-year-old tortures himself like this? she often thought, her heart aching at the sight.
Throughout the journey, Enya did her best to support him. She stepped in to help with healing when needed and taught him more about human anatomy—how the muscles work, how to avoid long-term injury, how to listen to his body.
And still... he kept pushing.
The road ahead was filled with challenges, but Enso knew one thing for certain: his journey had only just begun.
