After the Expansion Tournament, Kez was going to retire from competitive play.
Instead of retiring, Kez joined Team Dragon Knights in January 2015. They qualified for the spring season of NACS, beating Team Frostbite and Storm in the qualifier. They placed second in the season with a 7-3 record, behind Enemy eSports. In the playoffs, they beat Team Fusion 2-1 before losing to Enemy 1-3, sending them to the Summer Promotion Tournament. Despite the fact that they had placed higher than Fusion, Winterfox chose to play against them. TDK used substitute mid laner Alex Ich in their promotional matches and won 3-1, successfully qualifying for the NA LCS Summer Split.
Due to visa issues, Team Dragon Knights were unable to use their full roster for the first four weeks of the summer split, as Emperor and Ninja were unable to travel to the United States to play with the team. They instead substituted in LattmaN for Emperor and Bischu and mancloud for Ninja; Baby also substituted for Smoothie for their first three games. The substitute rosters went a combined 0-9, but when Emperor and Ninja finally joined the team for the second day of the fifth week, the team defeated first-place Team Dignitas. Despite that initial success, Team Dragon Knights were only able to secure two more victories over the next four weeks, and they finished in last place with a 3-15 record, one game behind Enemy. As a result, they were automatically relegated to the 2016 NA Challenger Series Spring Season.
From September to December 2015, Team Dragon Knights briefly renamed to Team Arena Online; they changed their name back due to concerns from Riot about the title sponsor Arena Online fulfilling their promises to the community regarding a million-dollar tournament circuit. Kez, Seraph, and Ninja stayed with the team through both renamings; however, Ninja was suspended for two months for his role in an attempt to recruit Samsung AD carry Fury while he was under contract.
