## Bio

First Korean athlete to win an IBJJF world title, Kira Sung took up jiu-jitsu at 19 after boxing sparked her curiosity, earning her purple belt in just over a year under Myung Hoon Choi at TNT Academy. She then moved to Seorae Jiu-Jitsu Academy under Hyuk-il Kwon, who promoted her through the ranks, while frequently training at Atos Headquarters in San Diego with André and Angelica Galvão. Her 2018 IBJJF World gold medal as a purple belt marked a historic milestone for Korean jiu-jitsu, and she received her black belt in March 2020 after a rapid 4-year-9-month climb from white belt.
