A restaurant named Red Cat Ramen is completely operated by cats! Its business prospers under manager Bunzou and the other feline employees: Sabu, Hana, Sasaki, and Krishna, who make sure that customers always leave with a smile on their face.

One day, a timid human named Tamako Yashiro comes in for an interview. To her surprise, Bunzou immediately hires her after discovering that she prefers dogs over cats. However, instead of preparing food or serving customers, she is assigned to brush her coworkers. Despite her last work experience leaving her with deep scars, Tamako's new job might be the place where she truly belongs.
