Jin is one of the members of the Shadow Channelers team during the Dark Tournament. The team's true name, however, was the Shinobi of the Spirit World. He is assumed friends with Touya, another member, since one is almost never seen independent of the other, except when fighting, and they stick together after the Dark Tournament. Jin has a cheerful and up-beat personality. Jin speaks with a strong Irish accent (in the English dub) and has a serious disdain for his team-mate, the brutish Bakken. He tells Yusuke that a fighter shouldn't bring outside hostilities and anger into a match, and that they should enjoy themselves - especially when they are battling for their lives. Despite his sunny disposition - or perhaps because of it - Jin is an incredibly talented fighter who throws himself whole-heartedly into a match. Jin's special ability is wind manipulation, being able to float in the air, create miniature cyclones around his fists, or create full-blown tornadoes.

Jin first appeared, along with the other members of the Shadow Channlers, in the Dark Tournament against Team Urameshi. Jin, just as he wanted, ended up fighting Yusuke Urameshi. After a long battle where each of them sent one powerful attack after another to their opponent, Jin finally got knocked out of the arena and lost. Unfortunately for Yusuke, due to a trick made by the team's owner, the battle was counted as a tie. Following the Dark Tournament, Jin later appears in the Makai Tournament. He was recruited by Kurama to work for one of the three Demon Lords, Yomi in the Demon Plane, or Makai. Jin trains under Genkai before entering the Makai Tournament, and goes from an upper C Class to an upper A Class. During the tournament itself, Jin ends up fighting Souketsu, who was a former friend and rival of Yusuke's ancestral father, the thunder god Raizen. A flashback is shown where Soketsu is defeated by the deceased king (Raizen).
