Lee "Kuzan" Seong-hyeok (Hangul: 이성혁) is the mid laner for Hanwha Life Esports.
Lee "Kuzan" Seong-hyeok joined the Jin Air Green Wings as a mid lane sub in January of 2015. He played his first competitive game in a set against Samsung Galaxy. He currently is the Green Wing's starting midlaner since GBM has left the team.
Jin Air played in the 2015 LoL KeSPA Cup where they lost 2-0 in the quarterfinals to CJ Entus. Jin Air also competed at IEM Season X - San Jose but they lost 2-0 to Counter Logic Gaming.
Jin Air started the 2016 LCK Spring Split strong, notably upsetting reigning world champions SK Telecom T1 on the first week. For the majority of the split, Jin Air held onto second place only behind the ROX Tigers, but fell down to fourth by the end of the season. Still qualifying for the Spring Playoffs, they beat the Afreeca Freecs 2-0 before falling 3-1 to eventual winners SK Telecom T1. This gave them a fourth place finish for the split.
During the 2016 LCK Summer Split, Jin Air went 7-11 in series score, netting them seventh place overall in the split. Kuzan shared the starting mid lane spot with Blanc. This made them barely miss the 2016 LCK Summer Playoffs for the season. However, their fourth place finish from last season gave them a berth into the first round of the 2016 Season Korea Regional Finals. In a close set against the Afreeca Freecs, Jin Air was defeated 3-2, ending their season.
