The group was created to promote the League World Championship and to sell in-game K/DA skins of the characters in League of Legends. The conception of K/DA was based on Riot's expressed desire to create more musical content, with the characters chosen based on K-pop archetypes. In 2022, "Pop/Stars" was certified platinum by the Recording Industry Association of America (RIAA), making K/DA and (G)I-dle the first K-pop girl groups in history to achieve this milestone.

In 2020, K/DA released their debut five-track EP All Out, which includes the pre-release single " The Baddest" and the lead single " More". A music video of the song uploaded to YouTube subsequently went viral, surpassing 100 million views in one month, reaching 525 million views as of August 2022, and topping Billboard 's World Digital Song Sales chart. K/DA was developed by Riot Games, the company behind League of Legends, and was unveiled at the 2018 League of Legends World Championship with an augmented reality live performance of their debut single, " Pop/Stars". (G)I-dle members Miyeon and Soyeon as well as American singers Madison Beer and Jaira Burns provide the voices of Ahri, Akali, Evelynn, and Kai'Sa, respectively, though the characters have also been voiced by other artists.

K/DA is a virtual K-pop girl group consisting of four themed versions of League of Legends characters Ahri, Akali, Evelynn and Kai'Sa.
