Fugirl

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. ~! Her real name is revealed to be Haru, the older sister of Taishi Yatsu who attacks Umio one day at work. !~
