Chapter 1: The First Link of the Chain and Loneliness in the Shadows
In the cheerful mornings of Konoha, as the sun filtered through the broad-leaved trees and struck the windows of the Academy building, every day was the beginning of a war for the seven-year-old boy. It was only the first few months of the first grade, and the children in the class had already split into cliques. The popular ones, those from powerful clans, and the "normals"... And then there was him; the boy no one could quite figure out, but who made everyone feel uneasy just by standing near him.
His story had begun far from Konoha's famous warmth, in a pale house in the most remote corner of the neighborhood. The only thing left to him by his family was an ambiguous bloodline and a heavy exhaustion resting on his shoulders. When he was only four or five years old, strange things began to happen when the other neighborhood children wanted to play with him. Once, during a game of hide-and-seek, in a moment of excitement, the air around him suddenly grew heavy; a nearby cat bristled its fur in fear and fled. After that day, the neighborhood mothers began to keep their children away from him, whispering "cold-breathed" behind his back.
When he started the Academy, this exclusion grew exponentially. No one wanted to sit next to him in class; while Iruka-Sensei gave his lectures, he always sat in the very back row with his head bowed. While other children tried to hold a leaf to their foreheads in basic chakra control lessons, he focused on stopping that wild flow within his body. Because he knew; the energy inside him was not a river, but a dam ready to burst.
"Hey, look at this guy! I bet he's talking to himself again."
Takeo and his friends appeared under the cherry blossom trees at the corner of the training ground. Takeo led the classroom bullies and had chosen this silent boy as his target. Our character had his eyes closed at that moment, trying to meditate to restrain that uncontrollable chakra (Nen). For a seven-year-old boy, this was a task as impossible as trying to empty the ocean with a cup.
"I'm talking to you! Why aren't you answering?" Takeo approached fiercely and kicked the training bag in front of the boy. "Iruka-Sensei said he'll do a kunai throwing test today. I wonder how a 'loser' like you is going to hold a kunai with those trembling hands."
The boy slowly opened his eyes. His hands were indeed trembling. This was not fear, but a shudder caused by his body's chakra pathways failing to adapt to this heavy and dark energy (Otsutsuki remnant: Satsujin-no-Nen). His chakra reserves were quite limited for a child, but the existing chakra was so dense and intense that his body struggled to carry it.
"Please go away, Takeo," the boy said, his voice shaking. "Right now... I don't feel very well."
"Oh, are you scared?" Takeo laughed, throwing his hand over the boy's shoulder and shaking him hard.
At that moment, the first crack formed in the dam. The "Stagnant Lake" in the boy's mind instantly turned into pitch-black mud. An icy energy, too intense to be explained by a child's chakra level, leaked out of his body. This energy wasn't even a technique yet; it was just a raw will bursting out uncontrollably.
"Let go of me!"
A black, smoky ribbon suddenly rose from the boy's shadow. Before this ribbon could take a full form in the air, it turned into a misshapen but eerie mass resembling a piece of a rusty chain. It was just a single chain link; weak, flickering, and unstable. However, it carried such a heavy killing intent that Takeo's hand went numb as if he had touched a block of ice. The chain only managed to push Takeo back a few centimeters before dissolving into smoke.
The boy collapsed to the ground, gasping for breath. Just manifesting that single link, and doing so uncontrollably, had exhausted all his chakra. Blood began to flow from his nose in a thin trickle. This was proof that a seven-year-old body could not handle this power.
Iruka-Sensei had entered the training ground at that moment. What he saw was not a display of "genius." The emotion awakening in Iruka's heart was not fear, but a deep pity. He ran to the boy's side and took him in his arms. The boy's body was burning with fever, but his hands were ice cold.
"It's over, Takeo, go back to class!" Iruka said sternly. Then he whispered to the boy in his arms: "Foolish child... You shouldn't push yourself this hard. This power is consuming you."
An hour later, when he opened his eyes in the academy infirmary, he saw someone in an orange jumpsuit by his bedside. Naruto Uzumaki was sitting on the edge of the infirmary bed, looking at him with curiosity.
"Whoa, you're awake!" Naruto said in his usual loud manner. "Iruka-Sensei said you were very tired, but I saw that black thing! It was so weird, like your shadow came to life!"
Shikamaru stood right behind him, sighing as he looked at his friend over the book in his hand. "Whatever that thing is, it's wrecking your body. Having your chakra flow so irregularly... It's a real drag."
The boy tried to hold the glass of water Shikamaru held out with trembling hands, but the water spilled. At that moment, a deep sadness appeared on his face. "I... I just want to be normal. But this thing inside me... sometimes it just wants to come out."
Naruto smiled and slapped his shoulder. "Being normal is boring! I'm going to be the greatest Hokage of Konoha, but everyone calls me a 'failure.' Look, we're outcasts too, but we forget everything when we're eating ramen!"
That evening, as our character walked towards Ichiraku Ramen with Naruto and Shikamaru, he felt a small darkness wrap around his arm. Nen-Hebi, that tiny snake in smoke form, had appeared for the first time. No one else saw it, but when the snake's red eyes met the boy's eyes, the boy felt a sense of "acceptance" for the first time. Whether this power was a gift or a curse, he didn't know yet. All he knew was that he carried a burden on his tiny seven-year-old shoulders that would shake the world.
Returning home after dinner, he whispered to the little snake emerging from the collar of his cardigan: "One day... will I be able to control those chains?"
The snake only hissed. The answer was hidden in the dusty roads of the future. When our character lay in bed 그 night, his hands were still trembling slightly, but for the first time, he felt the warmth of the friends beside him. A legend was being born in the shadows of Konoha; with pain, trembling hands, and a black chain of which not even a single link was fully formed.
