"Sumire-chan," age 31, is a former unsuccessful idol now living as a NEET. After being defeated in the cutthroat entertainment industry, both physically and mentally battered, she spends her days lazing around in a run-down apartment. Her high school freshman cousin, Yuusei, notices her situation and approaches her with a money-making proposition: "You've got a nice body, so why don't we publish an independent gravure photobook?" Can Sumire-chan stage her comeback in the Reiwa era? Stay tuned!
