Liberi's childhood is a mystery to all but himself. He has hinted at being born in Konoha and being a part of a black ops group during the war between Konoha ans Iwa, but there is no onfo on him after him that. Sometime during his teenage years, a small UNSC frigate crashed near a battle he had just finished. After showing his skill in a fgiht between himself and a few members of the crew, which resulted in five deaths and ten wounded, a doctor by the name of Leonard Church offered him a place within a new special operations group called Freelancer. Liberi accepted.
