|Occupation(s):||Amateur Contract Hunter|
Lin Koshi is a member of the team who come to the country of Kakin with Kite to conduct a zoological survey for its government. He is a short, bespectacled man who looks somewhat nervous and usually speaks with a slight stammer. In the team, he is the one who has discovered the most species for the survey. When he meets Gon and Killua in Kakin the number of species he has discovered is 1089. Kite says that Lin and his fellow amateur Hunters in the Kakin Exploration Team have excellent potential to be pro-hunters.
After the election for the 13th Hunter Chairman, Lin, together with Kite--now a female Chimera ant, a koala Chimera ant, Gon and the other 5 members of the Kakin Team, is seen in Stick Dinner and Spinner Clow's hometown, watching large herds of small-billed swans flying into the sky at sunrise.
