i solemnly swear

Killua was born as the middle child to a pure-blooded wizarding family of infamous assassins, the Zoldycks. Showing great promise from birth, Killua followed the traditional training to strengthen himself in the ways of magic for the next twelve years, set to be one of the best assassins the family has ever produced. Bored and tired of killing, he desperately wishes for something more in his life and to escape the responsibility of being the Zoldyck heir. Upon discovering Hogwarts acceptance letters hidden from him by his family, Killua unexpectedly rebels and runs away from home to attend Hogwarts. It is there where he meets Gon, a boy who changes his life forever.
