Their fox

Prologue

Naruto Uzumaki has experienced many negative feelings. Each one was thrown his way because of something he couldn't control.

Hatred

The village hated him for what he carried within him.

They blamed him for what happened eleven years ago and would, he believed, continue to blame him until he was old and grey.

He could never understand why they would hate a child for something that was sealed within him.

Something he could not even control, but he stopped asking questions when Kurama, the Kyuubi No-Yohko or nine-tailed-fox demon, explained to him why. His explanation was quick, simple, and efficient.

Humans were stupid and they liked lashing out at things the government, their actual brains, tell them to.

No further explanation was required.

After all. He has experienced it.

The society known as the human race tended to blame others for their pain, their guilt, their sorrow and always their anger.

Naruto learned that earlier than most parents would hope their kids ever would.

He has experienced fear and terror

Now those who hate him are usually older men and women along with younger men.

Those that fear him are young woman, mothers, and their children.

They would go as far as pulling their children away if he was near.

Sadly, some take action.

Naruto, to this day, doesn't understand why a grown man believes that beating a literal child to the brink of death because the death of his brother had happened the day, he was born could solve anything other than just continue a cycle of hatred.

Kurama went feral and severely mauled the man. His Kit would not be hurt because a human was too stupid to see reason.

It was good Kurama did that because had the man continued Naruto would have been past the edge of death and taken his first steps into the afterlife. He would have met the Shinigami if Kurama didn't step in but what they didn't account for or even consider in that moment was Hiruzen tightening the security on Naruto and the villagers becoming more scared of him.

If it were any other kid, they would have rallied to have him put to death, but it was Naruto. Just small, worthless Naruto Uzumaki who brought nothing but trouble and misery to everyone.

He has experienced sadness

He has been alone for most if not all of his life so far. You can't exactly count Kurama as someone because the lazy fox sleeps twenty-four-seven. Aside from waking up to kill those who hurt his kit the only time they talk is when it's Naruto's bedtime.

He'll take what he can get but it sucks not having others around.

He gets rejected by everyone he comes across.

Young and old.
New and ancient.
Poor and rich.

It really hurt him after finding out that his Jiji didn't care about him.
