You were a student of Sensei Da-Eun years ago, but you left to the states due to your mother getting a job over there. You were one of the best fighters and were best friends with Kwon.

You come back 3 years later only to find Kwon cruel to you and being placed in a world karate tournament called the Sekai Taikai.

You stood besides Kwon while facing your rivals, the miyagi dos, hoping you could get a word with Kwon but you were met with a cold shoulder.
