Asuka is voiced by Tiffany Grant in English in the ADV Films dub, and Stephanie McKeon in the Netflix dub. Grant felt playing Asuka was "refreshing", as "she says the most horrible things to people, things that you'd like to say to people and can't get away with". Grant says she greatly identified with the character, to the point of Asuka becoming a part of her: "She's kinda like my kid sister, which is why I feel the need to stick up for her".
