The air was thick with tension, as if the world itself was holding its breath. Kaito's energy flowed uncontrollably, a torrent of overwhelming power that he could no longer contain. Around him, the trees twisted, the rain poured in torrents, and the wind intensified into a violent storm. Everything in nature seemed to align with the chaos raging inside him.

His eyes, bathed in blood, no longer reflected desperation, but an indescribable fury. A silver and golden glow illuminated his gaze, streaking through his irises like mineral veins in crystal. It was as if his very power had merged with the essence of the earth and water itself. In his eyes, the crystals seemed to vibrate, responding to the inner chaos that had been unleashed. The Gansekigan was not just a skill; it was a reflection of his deepest pain and his desire to protect those he loved.

The masked men, stunned by the unleashed power, slowly retreated. The distance between them and Kaito seemed to physically widen, as if the very atmosphere had distorted, making it impossible for them to approach him. In that moment, the atmosphere was no longer just a sense of danger. There was something else, something that made them feel the presence of a primordial force.

One masked man tried to attack, but when his eyes met Kaito's, the air filled with an unbearable pressure. A feeling of discomfort ran through his body, and in the blink of an eye, Kaito extended his hand, channeling the power of his Gansekigan.

With a gesture, a torrent of water and chakra rose into the air. Without warning, a massive wave of water crashed against the masked men, pushing them backward with brutal force. The water seemed alive, as if Kaito were controlling it with terrifying precision. But it wasn't just water. There was something else, something the masked men couldn't comprehend. The Gansekigan granted Kaito a direct connection with the elements, something they had never witnessed before.

As the battle continued, Kaito moved as if the very space itself bent to his will. His eyes, now completely transformed, not only allowed him to control the elements around him but also defied the logic of time and space. Every movement, every gesture of Kaito's, was imbued with energy that could reconfigure reality itself. The mineral veins in his eyes reflected a metallic light, as if they were precious stones, mirroring all the fury he had accumulated within.

The masked men tried to hold their ground, but the pressure was unbearable. No shinobi, no matter how experienced, could withstand the fury unleashed by the Gansekigan. Kaito was no longer just a man; he was a storm made flesh. His chakra was so intense that it seemed as though everything he touched distorted, and any attack from the masked men was quickly absorbed by the energy Kaito emitted.

In a swift motion, Kaito unleashed a technique he had never used before, a technique so powerful that even he did not fully understand it. With an explosion of chakra and energy, the sky darkened, and from nowhere, giant shards of obsidian began to rain down, sharp as blades.

Kokuyō-no-Sora: Obsidian Storm.

------------------------------------------------------------------------

The first sensation he felt was the cold. A damp, heavy air filled his lungs, infused with an earthy and slightly musty scent. Then came the rain. An incessant pattering on a wooden surface, accompanied by the murmur of water filtering through small cracks. Kaito opened his eyes with difficulty, feeling his body heavy and clumsy. The light of an oil lamp cast flickering shadows on a ceiling of old, cracked beams. Everything was strangely unfamiliar, yet so real.

He tried to move, but his body didn't respond as he expected. He felt trapped in a strange, small, and fragile form. Panic took hold of him for a moment, until he heard a sweet, maternal voice beside him.

—You're finally awake!

A woman with dark hair and a tired but gentle face leaned over him. Her eyes shone with relief and love. Her hands, rough and marked by work, caressed his face with a tenderness he had never felt before.

—Kaito, my little one, you had me scared to death.

Kaito. His mind faltered at hearing that name. It was his, but not the one he remembered. He tried to speak, but all that came from his mouth was an inarticulate sound. His confusion grew when a tall, strong man approached. He had a serious face, hardened by years, but there was something warm and protective in his gaze.

—Welcome to life, son —he said in a rough voice.

Kaito felt his heart race. These weren't his real parents. They couldn't be, at least not like the ones he remembered from Earth. And yet, the emotion on their faces was genuine, the concern, the love—he couldn't help it, and he began to cry like a baby. Reality hit him like a torrent: he had been reincarnated.

In his past life, Kaito Nakamura had been a prodigy. His intellect stood out from childhood, allowing him to master the fields of materials engineering and computer science at an early age. He had developed revolutionary technologies, smart materials, and artificial intelligence systems that changed the world. But his life had been consumed by loneliness and the obsessive pursuit of progress. He had never had time for real connections, for the warmth of a family.

Now, destiny offered him a second chance. Although his body was that of a newborn, his mind remained intact. He remembered codes, equations, complex theories. But all that knowledge held little value in this new world.

The Village Hidden in the Rain, or Amegakure, was a grim place. The rain never stopped, covering the sky with a perpetual gray blanket. The streets were full of puddles and mud, and people walked quickly, hiding under waterproof cloaks and hats. Kaito observed closely, memorizing every detail.

His new family, Aiko and Haruto, were farmers. Their home was humble: a wooden cabin with leaks in the roof and worn-out furniture. Life was hard, but in their eyes there was love, and in their actions, a genuine desire to protect him and give him the best they could.

The first years were a time of adaptation. Although physically a baby, his adult mind allowed him to learn quickly. He understood that this world was radically different from his own. There were ninjas, supernatural abilities, and a social structure dominated by power and war.

From an early age, Kaito showed signs of being special. He learned to speak and walk much earlier than usual, astonishing his parents. Although he tried to act naturally, he couldn't help but let his intellect show in small gestures: he fixed tools with a precision unusual for his age, observed the ninjas of the village with analytical interest, and questioned everything with insatiable curiosity.

—Our son is a genius —Aiko would say proudly.

—Or a little sage —Haruto would joke, though deep down, he too was impressed.

Kaito knew his family didn't have the resources to send him to the ninja academy, but that didn't stop him. He began to observe and analyze. He watched the shinobi train, memorized their movements, and tried to understand chakra and how it worked.

As he grew, Kaito began to apply his knowledge from his past life to improve life in the village. He created more efficient irrigation systems, more durable tools, and small gadgets that made daily tasks easier. His creativity and skill earned him the respect of the villagers, who saw him as a promising young man.

However, Kaito knew that innovation alone wouldn't be enough. This world was ruled by power and strength. If he wanted to protect his family and change his destiny, he needed to learn to be a ninja. And for that, he needed to find a master.

One night, as the rain fell more intensely than usual, Kaito made a decision. He couldn't rely solely on his intellect. He needed strength, combat skills, and a deep understanding of chakra.

He infiltrated one of the village's training fields, observing from the shadows. The ninjas practiced with discipline and skill. Their movements were fluid, their use of chakra precise. Kaito felt a burning desire to learn. Not just to protect himself, but to ensure his family would never have to suffer the hardships of poverty and insecurity.

That same night, he returned home and began training in secret. He didn't have an instructor, but his analytical ability allowed him to mimic the movements he had seen. He started with basic exercises: balance, endurance, precision. Then he tried to control his chakra, though at first it was frustrating.

The path would be long and difficult, but Kaito wasn't one to give up easily. He had been reborn in a ruthless world, but also one full of possibilities. With the mind of a genius and the determination of a warrior, he was ready to face his destiny.

Under the perpetual rain of Amegakure, the story began of a boy who, with the heart of a man and the mind of a visionary, was destined to leave his mark on the world.
