KuroKy grew up in Berlin, Germany.KuroKy suffered from disabilities to his legs, and would struggle to use his legs. He stated that this weakness was what led to him to play video games.
KuroKy played for a few German DotA teams before joining his first international team, mousesports, where he played with players such as Drayich. This mousesports lineup attended DreamHack Winter 2008 with Puppey acting as stand-in; this was to be the beginning of a long relationship between KuroKy and Puppey. KuroKy then joined Ks.int, which at one point had a total number of 9 players and looked more like a mix than an actual team. Some well known players in the DotA scene were on the team, such as Puppey, Vigoss and LevenT.
2011 - 2012: Early Days
KuroKy's first public appearance in Dota 2 was The International 2011 along with the game's debut at Gamescom. He participated in the tournament under GosuGamers.net with teammates Kebap, Azen, and Mirakel. Unfortunately for them, they dropped all three group stage games and were eliminated by MiTH.Trust in the first round of the losers' bracket.
After the unsuccessful run at The International, KuroKy went on to play in several other teams with him as the star player; the teams included PANZER and 10,000th, which were also jokingly called KKy + 4. In May 2012, he joined Virtus.pro in the hopes to qualify for a spot to play at The International 2012. They won their first round match of the West Qualifiers against mTw but were eventually eliminated by mousesports and zNation. However, he got his chance to play at The International 2012 when ComeWithMe ran into visa issues and mousesports invited KuroKy to the event in his place. A stroke of luck for KuroKy and the other mouz players happened when MUFC ran into visa issues and could not make it to Seattle, leaving an extra spot for the backup teams. mouz played a best of five series against World Elite to determine who would replace MUFC in the main tournament and they took the wildcard match handedly with a 3-0 score. The main tournament itself was not a success for KuroKy as he was knocked out in the first round of the playoffs and could not improve upon his results from The International 2011.
KuroKy joined mousesports on September 16 as a temporary member, along with Alex and Kebap, to fill their roster for SLTV Star Series Season 3.
Originally intended his nickname to be pronounced kuːroʊkaɪ, but is fine with people pronouncing it differently.
