Corporate Office Lady Chie Maru Diary

We follow the life of Chieko Tsukimaru, commonly known as Chiemaru, who is working in the sales department of a black company and tries to be cheerful and positive. Chiemaru's aim of becoming a "bari-carrying sales OL" is halted by harsh quotas, a rough work environment, a demonic boss and strict seniors. What is the fate of Chiemaru, a "company slave OL" who joined the black company?
