permission. Mito, his Aunt-known-mother didn't allow him so they made a
condition. Once Gon catches the GIANT fish in the lake, he gets to go to
the hunters test and find his father. Gon did catch the fish and Mito
lets him go ad tells him that all she told Gon about his father leaving
him is a lie. Gon sets off, meets Leorio then Kurapika. They become
friends in a situation in the ship and went off together helping each
other in the test. He also meets Killua Zoldick during the test and
Killua, considering that he is the same as his age and Gon's sense of
friendliness, became interested in him and became good friends. They
pass the test except Killua. After the test, Killua was forcefully sent
back to his home and Gon, Kurapika and Leorio went to save him and
successfully did the mission. After that, they went on their own lives.
