Black Cat Cafe is located in the fifth ward of the Imperial Capital. Having lost their purpose after the war ended a few years prior, advanced mechanical dolls known as Automata have been restored and now work at the cafe wearing elegant kimonos. While they adjust to the peaceful world, events of the past continue to haunt the Automata, preventing them from letting go of the responsibility they once held.
Among the Automata working at Black Cat Cafe is the recently restored Haizakura, who has lost her memories during a reset. Her identity and role in this unfamiliar world are a mystery to her, but one thing is certain—she loves to sing. With never-ending curiosity and beautiful songs to guide them, Haizakura and the Automata search for their new purpose together, supporting each other no matter how rigorous that endeavor might be.
