Gon Freecss

The boy who found Ging — and burned out his Nen doing it. Not aboard the Black Whale: after the election he discovered he can no longer see his own aura, and on Ging's advice went home to Whale Island to live with Mito and figure out what he wants next.

Addendum ch.345Ging's read on his condition: the aura is probably still flowing — Gon simply can't perceive it anymore. 'You went back to normal. Be thankful that's all it cost.' Gon admits finding Ging was the goal, not staying with him.

Addendum ch.414When Kurapika imagines mainland friends who would protect the real Woble without question, the faces he pictures are Gon's and Killua's — the first thread tying the boys back into the war.
