Not entirely sure if I’d classify her as a “waifu”, but:
Yennefer of Vengerberg, from “The Witcher 3: Wild Hunt” <3
She truly ranks as one of my all-time favorite videogame characters. First off, she is GORGEOUS, in pretty much every way (in my book); and I also find her personality very alluring. It also helps that, if they were to make a “Witcher” movie or TV series, Eva Green is THE actress to play her XD With all those points in mind, she was what compelled me to actually first buy the game and get into such an awesome game series ^^
