The debut of K/DA, the virtual girl group of four characters from online arena video game League of Legends, in 2018 could have ended as just a one-time gift for devoted fans of the game.

However with the release of the group’s first single “Pop/Stars” and their real-life stage performance at the 2018 World Champion Finals opening event in South Korea that year, the song, in addition to the four members– Ahri, Kai’Sa, Evelynn and Akali– received recognition even beyond the initial gamers, building their own fan base. The song topped the K-pop category of Signboard’s World Digital Tune Sales chart and its video racked up over 20 million views in simply four days.
