K/DA (/keɪ diː eɪ/ kay dee ay[1]) is a virtual K-pop girl group consisting of four themed versions of League of Legends characters Ahri, Akali, Evelynn and Kai'Sa.

[3] 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.

K/DA has subsequently achieved significant popularity both within and beyond the League of Legends fandom and received critical acclaim, particularly for their performance during the World Championship and the impact of gaming on the music scene.

[5] During the ceremony, Beer, Burns, Miyeon and Soyeon performed "Pop/Stars" on-stage, whilst augmented reality versions of the characters they voiced sang and danced alongside them.

They eventually decided against a cuter, more-idol group based theme in favour of something "modern and edgy" that combines a "bit of street style with a handcrafted feel.

[12] In Teamfight Tactics, for the game's 10th set Remix Rumble the roster of champions were primarily drawn from the League of Legends music-based skins, including all of the main members of K/DA as well as Seraphine.

[14] "More" is featured in Just Dance 2023 Edition with two different routines, one with the coaches in their All Out outfits and the other with Seraphine in her bedroom backdrop from the original music video.

[5] The creation of K/DA was based in part on the desire of Riot Games, League's developers to "see their company more as a full-fledged music label in the future".

[19] Subsequently, with Ahri being a "beautiful, charming leader"-type character, Evelynn was chosen to contrast to that, by "being the wild and provocative diva of the group".

[19] Kai'Sa was included due to a recommendation from skins lead Janelle Jimenez, as she wanted a "strong but silent loner who expressed herself on stage through her movements".

Writing for Dot Esports, Aaron Mickunas noted that "It didn't take long for K/DA [...] to completely flood the game's fan community.

[7] The "Pop/Stars" music video received 5 million views within 24 hours of its upload to YouTube, breaking the record at the time for the most viewed K-Pop debut group music video within 24 hours of publishing, a record previously held by "La Vie en Rose" by South Korean-Japanese girl group Iz*One.

[29] Benjamin Pu of NBC News wrote that "The song's popularity highlights just how much of a cultural force video games have become in South Korea and around the world.

"[5] Riot's Patrick Morales agreed, noting K/DA's impact goes beyond just that of League fandom, with "one recurring comment that I tend to see on YouTube and social media about the music video is that they're "normally not into League/K-pop/gaming, but K/DA is the exception".

[34] Lucas Lockyer of Dazed called K/DA a mix of "Girls Generation meets Little Mix and Hatsune Miku" and asked if the band was "leading the virtual pop future", where "what was essentially some creative promotional marketing could be the forefront of an interesting new branch of pop [...] Perhaps with developed AR technology, the characters could tour in hologram form without the physical appearance of the singers behind them.
