Sadako runs Sophie's fan club and takes the role seriously—she's basically dedicated to looking out for Sophie. She's got long, layered dirty blonde hair with bangs and blue eyes, and she's pretty recognizable thanks to the pink headband with an "S" she wears. You'll usually spot her in her Sophie's Fan Club jacket over her school uniform.
She attends Paprika Private Academy. Whether she's an active idol herself or mainly uses PriPara as a way to manage her fan club duties isn't entirely clear, but either way, that's where she spends her time.
