Ha "Hachani" Seung-chan is currently a substitute support for KT Rolster.
Ha "Hachani" Seung-chan joined KT Rolster Arrows in October 2013 as their new support, originally under the name "Renewal". This new KTA team played their inaugural OGN at HOT6iX Champions Spring 2014. They managed to upset SK Telecom T1 K in the group stage and made it to the quarterfinals but they lost 3-1 to CJ Entus Blaze. HOT6iX Champions Summer 2014 was KTA's breakthrough season, where they upset Samsung Blue 3-2 in the finals to win the OGN Championship. KTA managed to qualify for the 2014 Season Korea Regional Finals but they lost 3-0 to NaJin White Shield in the second round. In the 2014 season, Hachani became known for an early-roaming playstyle, sometimes leaving lane as early as level 3. He was considered a somewhat hit-or-miss player, sometimes getting caught out repeatedly while warding, but also sometimes being in the right place at the right time and setting up plays for his team.
Hachani remained with the KT Rolster organization following the Korean region's change to allowing only one roster per organization. He played with them in the Champions Spring 2015 Preseason, where they tied for third with the HUYA Tigers with seven points (though the event was not prized). At the halfway point of SBENU Champions Spring 2015, KT Rolster were in seventh place, ahead only of Samsung Galaxy, with a 2-5 set record and a 5-11 game record. At this point, Hachani requested a break from play, which was granted by the KT organization. His spot was filled by Fixer. Hachani joined Rebels Anarchy as a coach in July of 2015. Anarchy finished eighth in SBENU Champions Summer 2015, missing playoffs but qualifying for the next season of LCK.
Anarchy participated in the 2015 LoL KeSPA Cup but lost 2-1 in the quarterfinals to Ever. Hachani left Anarchy on December 22nd to join KT Rolster as a substitute support.
During the LCK 2016 Spring Season, KT Rolster finished second place in the regular season with a 13-5 match record. For the majority of the split, KT favored starting Hachani as their support, rather than Ignar, who left the team in March. Their regular season placement earned them a bye into the semi-finals of the Spring Playoffs, where they faced SK Telecom T1. Unfortunately, they were swept 3-0, ending their spring split with a third place finish.
