How can one hope to survive, if they were hated from the start?
This young child had the world against him before he was born. Created to be a monster, by having a monster implanted into him while he was still in his mother's womb.
He never had a choice.
When he came into the world, the boy arrived earlier than anyone expected. He was so tiny that he could fit into the palm of a hand. It was a miracle that he was able to breathe without any trouble.
That had to be the only good thing about having a demon inside him.
Due to the complications during the early childbirth, the boy lost his mother just after she able to greet and hold him. His big sister and brother blamed him for their mother's death.
Only a few minutes old and his siblings already loathed him.
Despite the rough beginning of his life, the boy had a positive and hopeful outlook on life, because he had one person that cared for him. Adults mistreated him verbally while children ran away when the boy was only offering his assistance. He was shunned as the outcasted son of the Fourth Kazekage.
But at least he had his beloved uncle. The boy's uncle—who was his mother's brother—always treated the boy with the love and respect he needed to grow. No one else treated him the way that his uncle would and that kept him as the hopeful child he tried to be.
Then the boy's life changed forever on that fateful night—
Where his uncle tried to take his life.
The boy has been harmlessly gazing up at the full moon on a roof top when the sand suddenly lunged at something behind him.
Now, in all honesty, the boy only had partial control of the sand that surrounded and followed him. The monster inside him controlled it the rest of the time to protect the boy. If he were to die, the monster would potentially die too. They were tied to each other, whether the boy liked it or not.
Anyways, the boy couldn't hide his surprise at seeing his uncle now laying on the ground, hanging to his last few dying breaths thanks to the sand. The boy was completely horrified at what he saw, demanding to know why his loved one tried to hurt him.
His uncle's dying words claimed that he and the boy's mother never loved him. The uncle was ordered by the Kazekage to kill the boy, because he was a monster that could and would never be loved.
Outraged by the declaration, the boy decided to let the monster inside him roam free. It has been harassing the boy for years about how it would take over his body if he were to sleep for even a moment. The boy cautiously stayed awake to prevent that from happening.
But now, the boy no longer cared.
Using the boy's body as his puppet, the monster rampaged through the village. Destroying everything in its path and anyone that got in its way, the monster was indestructible—
Until the Kazekage somehow managed to tame the monster and force it back inside the boy, not that it really mattered anymore. That day caused the boy's heart to grow black with hatred and despair. He was now determined to destroy or to kill anyone that got in his way.
The boy believed he would always be a lonely jinchuriki.
That is . . . until he met the moon-eyed princess and her fox of a friend—
Who was just like him.
