Lee "Kuro" Seo-haeng (이서행) is the MidLane Icon.png Mid Laner for Afreeca Freecs.


Season 3
Lee "KurO" Seo-haeng began his career in professional gaming in March of 2013 with Incredible Miracle 2. This team was unable to make it out of the quarterfinals of the HOT6iX Champions Summer 2013 league, but were able to place 2nd in the GIGABYTE NLB Summer 2013 league with a 1-3 loss to NaJin Black Sword.

Season 4

KurO remained with IM2 to attend PANDORA.TV Champions Winter 2013-2014, where the team was again knocked out in the quarterfinal round. Then, after IM2's even poorer performance at HOT6iX Champions Spring 2014, KurO left to join NaJin Black Sword. He played with NJBS in the HOT6iX Champions Summer 2014 series where, unfortunately, the team was defeated in the quarterfinals in a 2-3 loss to SK Telecom T1 S.

Season 5

On October 31st, 2014, KurO's departure from NaJin Black Sword had been announced. Shortly after, on November 14th, 2014, KurO joined the HUYA Tigers along with Smeb, Lee, PraY, and GorillA. This team played in the 2015 LoL Champions Korea, where they renamed the team to GE Tigers. This team far surpassed KurO's past teams' history of mediocre performance, doing well at the start of the 2015 season and earning an invitation to the IEM Season IX - World Championship. It was there that the team fought their way to the semifinals, losing only in a 1-2 reverse sweep to Team WE who, in turn, were defeated by Team SoloMid. After returning home, the team proceeded to play in the Champions playoffs due to their first place standing in the regular season. The Tigers made it to the finals where they lost to SK Telecom T1 in a 0-3 sweep and placed second in the entire tournament. The Tigers then played in the 2015 LCK Summer series under a slightly changed name, the KOO Tigers. It was there that they placed fourth in the regular season and qualified for the playoffs but lost in the semifinals to KT Rolster in a 2-3, back-and-forth match. After the summer playoffs ended, KOO was picked as the second seed to the 2015 World Championship due to circuit points. There, KOO performed well in their group, losing twice only to the yoe Flash Wolves. In the bracket stage, they knocked out KT Rolster 3-1 and swept Fnatic 3-0 in the semifinals. Unfortunately, they were unable to wrest the world championship cup from SK Telecom T1, losing 1-3 in the grand finals.

Season 6

Prior to the 2016 season, KOO Tigers changed their name to ROX Tigers. The ROX Tigers finished the LCK Spring 2016 Split in first place with a 16-2 record. In the finals of the LCK Spring Playoffs, ROX Tigers were defeated by SK Telecom T1 in a 3-1 fashion. In the regular season of the summer split, they were once again able to finish 1st with a 15-3 record. This time around, their opponent in the final wasn't SK Telecom, it was KT Rolster. In a very close series that became a classic, ROX was able to win it (3-2) and capture their first LCK title since they were formed.

ROX Tigers went to the 2016 World Championship as the #1 seed from the Korean region. This is Kuro's 2nd Worlds appearance, unfortunately, they did not make it to the Finals this time, as they faced their 2015 Finals opponent in the Semifinals round of the bracket stage. Kuro made it out of the group stage as #1 seed with a 5-2 standing. They were then seeded against EDward Gaming in the Quarterfinals, beating the Chinese team in a 3-1 victory. However, they faced SK Telecom T1 in the Semifinals and although the games are close, they were still overpowered by their rival, ending their Worlds run at 3rd-4th place.

Despite losing at Worlds, Kuro was able to take home another trophy. They won the 2016 LoL KeSPA Cup after beating SK Telecom T1 in the Semifinals and Kongdoo Monster in the Finals. Then again, this victory was followed by the news of the Tigers' disbandment. On November 24th, the team announces the free agency of Kuro along with his teammates and Coaches. Weeks after, Afreeca Freecs made an announcement that the team signed Kuro as their starting Mid Laner for the 2017 Season and he will be teamed up with MaRin, Kramer, TuSin, Spirit and Mowgli.
