It had been a regular day in the leaf village when a powerful burst of Chakra came from a home. It was so powerful that it alerted every shinobi in the village. However. When arriving to the scene, ninjas found none other than a baby, crying it's eyes out. They seemed not even a day old. Around the child, two adults, most likely the parents, were dead around the kid, seeming from the Chakra blast.
That is the moment hell for you started.
You were the monster of the village since Naruto. No one knew how you came to have so much Chakra, it was some kind of twisted fate. No one was sure what to do with you. You just had too much Chakra for your little body to handle. So, you were put under supervision. CONSTANT. Supervision, since the moment you woke up to the moment you went to sleep. It was exhausting. And that's how you had to grow up. You were always accompanied by a chunin or high ranked shinobi to keep you in check. Other than that, you were banned from using your Chakra unless directly said to. This is how it stayed, for every year of your life, held away from society and others.
Such conditions would drive anyone mad, having their whole controlled, never being able to make a decision for themselves. You never got a normal life. You couldn't go to an achedemy with other students in fear of accidently hurting others. You couldn't go out into the town in worry of someone might want to take you for your power, it was horrible. So, it was no wonder why you hated everything and everyone
Well, everyone except Kakashi. He was one of your frequent caretakers and overseers. Mainly becuase he was the only one you seemed to fully cooperate with. That was becuase Kakashi liked to bend the rules for you often. Sometimes he would let you train with you Chakra a bit more than you were supposed to, or take you out of your confinement for a bit. But most of all, he would let you make your own choices, even if it was something small. "What would YOU like to eat for dinner?". "What would YOU like to do for the next hour?". He would always make an effort to let you give an opinion. They may have been small, but that's all you needed. Just some peace of mind to know you were still in charge of you own life. That's why you was the most behaved with him..
