Manager Buffalo is an office worker and a supporting character in the 1-minute TBS Television shorts. He makes a short cameo in the Netflix Original series while trying to open up one of Tsubone's impossible jars. Buffalo is based on a Water Buffalo. He has black fur and hooves, and a gray nose and horns. His office attire consists of a white dress shirt with a red tie, black pants, and brown dress shoes. Buffalo is a terrible shift manager who is often late and makes sloppy schedules. He spends his days leisurely chatting away and ignoring all work that needs to be done until the last minute when he passes it off to other accountants, mostly notably Retsuko.

Some offices have stereotypical dynamics: the chauvinistic pig of a boss who never does any real work; the employees whose goal is to suck up to the boss; the ones whose lives seem perfect; and the individuals who have all the actual work pushed onto them. Retsuko the red panda is in the last group, as she stays late most nights to make up the work her coworkers are too lazy to do themselves. Her relief from the stress of her everyday life comes in the form of singing death metal at a local karaoke club. Night after night, Retsuko channels her grief into a microphone and considers the place to be her own personal sanctuary. But as she moves further away from her comfort zone and the ideas people have of her, she discovers that letting others into her world of death metal may not be such a bad thing.
