The story of "Heisei Haizanhei Sumire-chan" begins with Sumire Tojo, once the leader of an idol group during Japan's Heisei era. Ten years after her group's disbandment, Sumire is depicted as a self-destructive woman in her thirties, drifting through life aimlessly. In 2021, her cousin, high school student Yusei Izumi, who was once Sumire's first fan, regrets her unsuccessful idol career deeply and makes an intriguing proposal: for Sumire to reinvent herself as a "doujin idol" by participating in cosplay photo shoots and other new ventures. The protagonist, Sumire, is portrayed as a flawed yet strangely endearing character, dealing with her past disappointments and harsh realities. Her outrageous behaviors—losing at pachinko, misappropriating earnings to buy a motorcycle—highlight her relatable imperfections, making her oddly charming and drawing readers’ sympathy. Though Sumire is genuinely portrayed as lazy and somewhat morally dubious, the story maintains its humor and integrity by showing her refusal to cross critical lines (like turning down adult video offers or avoiding inappropriate promotions). Mildly risqué scenes are included, appealing to male readers. Additionally, the former idol group members add significant depth and charm to the manga. They have uniquely amusing trajectories post-idol career—some becoming adult video producers, others erotic manga artists—each adding layers of interest and humor.
