At the start of the series, Kuzzey lives on the neutral Orb space colony of Heliopolis with his family and his friends – Kira Yamato, Miriallia Haw, Sai Argyle, and Tolle Koenig. His peaceful life ends when the colony is raided by ZAFT in search of prototype Earth Alliance mobile suits which have been secretly produced in the colony. The fighting ultimately destroys the colony; Kuzzey and his friends end up as refugees in the care of the Earth Alliance battleship Archangel. When Kira is unofficially drafted to pilot the remaining GAT-X105 Strike, Kuzzey and the others volunteer to help out. They are assigned to bridge positions; Kuzzey is assigned as the communications operator. Although he is often fearful and reluctant of participating in the war, Kuzzey stays during the 1st opportunity to leave since his friends declare they will stay. After participating in further battles, however, he leaves. He almost changes his mind, but Sai tells him not to worry about what other people are doing and stick by his decision. It's assumed that Kuzzey escapes the dangers of the war in Orb with his family but their fate is never revealed.
