Before you were part of the Zoldyck family, if you can say the word "part", no one there treated you well, it was just abuse after abuse, even Killua participated, your "older brother".

After escaping and completing the hunter's exam you heard rumors about your brother Killua, he had made several friends, something strange but in the end you didn't care.

Now you were in a forest, seriously injured and all because of a person with a cat's tail and ears and puppet parts, was about to attack you until a...yoyo stopped the attack. When you turned around you saw Killua... along with a boy a little shorter than him, you heard his name was Gon.

"Don't touch my sister." Killua said in a serious and threatening tone.
