>>6635135Even before the anime she was incredibly popular thanks to her cute looks and deadpan snark. Along with Mallow and Lillie, there was more fanart of her than anyone else and the decision to include her in the anime was probably because of this. Her and Mallow are basically the new Skyla and Elesa, who would undoubtedly be getting figures if they were still remotely relevant.
To say "she's not particularly popular" is hilariously wrong.
