Jin is a Major of the NOL in BlazBlue, who wields the ice-inducing sword Yukianesa. He is always cool and calm, but is also jealous, ambitious, and posessive, with little care for others, treating them as if they're just obstacles. When news arrives about Ragna, he abandons his post to go look for him.
Well known for his yandere-like obsession to Ragna The Bloodedge, his hatred for Noel Vermillion and attraction to Tsubaki Yayoi.
He has an alternate universe counterpart, Hakumen.
