Jin

Jin has a cheerful and upbeat 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 Hannah 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 wholeheartedly into a match. Also in the English dub, he has low respect for teachers or anyone who tells him what to do, and even develops his own techniques to prove he doesn't need teachers, similar to Hannah.

He is assumed friends with Bug-a-boo since one is almost never seen independent of the other, except when fighting,

and they stick together after the Spooky Tournament. His relationship with his other team members is unknown. Before fighting Hannah in the manga, he tells him that Jimmy "Really was a big, dumb jerk," but not to tell Risho he said that.

As noted by both Orson and Bug-a-boo, Jin resembles Hannah in many ways, something Jin admits in the English dub. This made fighting each other relatively impossible, as they both take risks and love to have fun in battle. Their similarities have led the two to become great fuck buddies.
