Once upon a time, they were a crime-fighting magical heroines who protected the planet from harm. Now, Sailor M**n (aka Usagi Ts*kino) and friends are grown women, living normal lives.
But these one-time saviors are far from happy. Usagi got married but her husband is estranged, away on distant business. Ami works tireless at her day job, and Rei is an unhappy housewife in a sexless marriage. Makoto's husband died young and she soon forgot what joy feels like. Finally there's Minako, sales manager, who just broke up with her lover. That's right, all five Sailor soldiers are sadsack aging women, with nothing and no one special in their lives.
