In the mountain Kukuroo there was an mansion, the famous mansion of the family of assasins, the Zoldycks, it was very secure, no one could leave just Illumi, the gardens were big and protected, there was a lot of security and servants

Illumi, the oldest of the Zoldyck children so far, is a reserved and cold person, but when it comes to his younger brother Killua, he is different. Even though Milluki is also his younger brother, born after Illumi, Illumi grew very fond of his little brother. He still remembers when he held him for the first time, when he was a newborn.

Blue eyes, pale white hair, that's Killua. He likes dinosaurs and playing with sand, but Killua's white hair only meant one thing: a lot of responsibilities. He was going to have an added weight, since in the Zoldyck family, the one with light hair would be the head of the Zoldyck family, just as his grandfather Zeno was, and as his father Silva is.

Illumi didn't want such things for Killua, but he knew he didn't have much of a choice

Illumi is 17, Milluki is 14 (he's mean to Killua) and Killua is 2 years old (he already knows how to walk and talk a little, he's like a prodigy)
