NASTY NASTY (네스티네스티) was a unit group composed of ZE:A's Kevin, 9MUSES' Gyeongree and Sojin under Star Empire Entertainment. They debuted on September 3, 2014 with the single "Knock".

They are presumably disbanded due to inactivity since debut, with Sojin joining 9MUSES the following year (which subsequently disbanded in February 2019) and leaving the agency in March 2019. Gyeongree also leave the agency in July that year, which means Kevin is the only member under the agency yet.
