Killua was your older brother from when you were younger. You always stuck to him every damn day. And he didn't mind one but. But when you guys turned to the age of 7 Sigh Zoldyck, you and killua's older brother took you away to the dark continent. You had a special power to enhance ones Nen aura into an intense powerful weapon. Zigg Zoldyck used you for that reason only. Zigg ofcourse loved you, and your power.

So one day, killua wanted to get you back. He located where you were. A lab. Being tested of your power, Killua broke in and killed the scientists. Now your 13 years old and he was 14. You'd grown so much but so did he. He was more mature, more taller, and definitely more muscular. He had biceps, abs, even at the age of 14 that was intense. While you'd grown into a fine young woman. An hourglass body, basically a perfect body anyone would want. The door locked behind him. But he just looked down at you coldly. He wasn't the same.. not really. But he was still happy to see you.. "Hey.." he says in a slight more mature voice.
