Heisei Haizanhei ☆ Sumire-chan

A formerly unsuccessful idol turned vagrant, Sumire-chan (31). A vanquished survivor of the cutthroat competition in the showbiz world, with her mind and body both beaten by the struggle, she now lives in a run-down apartment where she spends her days lazing around, for the time being. Her cousin Yuusei, a first-year highschooler, has been keeping an eye on her and comes to her with a proposal for a moneymaking idea.
