A chubby, shortstack office worker. Fenneko's appearance is based on a Fennec Fox. She has light fawn fur across her entire body except for a dark fawn tripoint stripe down her forehead. She has a noticeably short height. Fenneko is quiet, perceptive, and can easily figure out what her co-workers are thinking just by watching their mannerisms. Fenneko thinks it's hilarious when Retsuko puts herself in embarrassing situations at work and is rightfully angered by how the higher-ups treat Retsuko.
