This is not a real K/DA cover. It's just a fanmade video for entertainment purposes.
The choice of singer/character is my own interpretation as you might've seen in the past. Sometimes I swapped the characters my (G)I-DLE - K/DA lineup is:
Akali - Soyeon
Ahri - Miyeon
Evelynn - Minnie
Kai'sa - Yuqi
Seraphine - Shuhua
All the videos, songs, images, and graphics used in the video belong to their respective owners and I or this channel does not claim any right over them and will be taken down upon request.
