Fugirl 腐ガール

Rotten Girl is a female employee of the Horse's Bone bookstore.

She received her nickname "Rotten Girl" not because she is a fujoshi/yaoi fan as the name would imply, but because she's a huge fan of zombie media. Rotten Girl is obsessed with zombies to the point of sometimes attacking others whenever they display zombie-like behavior. She frequently pairs up with Sommelier despite the glaring difference in height.

Appearance-wise, she is short and has short red hair. She is still in high school and lives together with her family.
