Monstar KittenZ climbed the Ranked 5's ladder, and qualified for the LCS 2015 Season Expansion Tournament but then lost to compLexity.White 1-2 in the first round of the tournament. After the Expansion Tournament, xSojin left Monstar Kittenz.
xSojin joined TSM Darkness before the start of the third week of the NACS Spring Season, replacing Azingy as their starting jungler after his move to Team Dignitas. He jungled for one week, then didn't play in the fourth week, and then started as AD carry in the last week after t3azer was revealed to have leaked scrim footage to Team Fusion. The team finished fifth overall in the season, after winning a tiebreaker game against CLG Black. After multiple renamings of the team, xSojin left shortly after the start of the 2015 NACS Summer Season.
