Kolme, originally known as Callme, is a Japanese idol trio formed in 2014 by former members of Dorothy Little Happy: Ruuna Akimoto, Mimori Tominaga, and Koumi Hayasaka. The group debuted with the single "To Shine" in 2015, and all three members left Dorothy Little Happy later that year to focus on the new project. Their debut album, Who Is Callme?, was released in 2015, followed by This Is Callme (2016) and a string of singles, which all appeared on the Oricon charts, including "Can Not Change Nothing", "Confession", "Bring You Happiness", "One Time", and "Hello No Buddy." In September 2018, the trio adopted the name Kolme and continued releasing music with the albums Hello Kolme (2019) and Do You Know Kolme? (2019). They later issued their first EP, Hajimete no Mini Album, in 2022.
