Yu Mashiro, a former delinquent who was feared as the "White Tiger of the West," pursued her dream of working in print design, and landed a respectable job at a small printing company in the suburbs of Tokyo. Of course, she tries to hide her notorious past... She is thrilled to have a job that allows her to work on the manga she loves, but she is also subjected to the usual hassles of life at a printing company and teasing from her seniors, who have their own quirks, which is making her delinquent temperament on the verge of exploding in full force. This is the start of a work comedy in which Mashiro, who is single-minded in everything she does, struggles through the rough and tumble life of a printing company! (Source: Comic Days, translated)
