Kokonotsu Boshi Girls' Academy of Commerce, a school built on the site of an ancient castle, known as "Shirojo." Toomi Yuna spends her time here at her expense, until one day her lunch on the roof is suddenly interrupted by a pair of ghosts.
Enoki Sachi, who died in an accident before the war, and Nagatani Megumi, who died of illness thirty years ago. These "soul mates" died with unrequited feelings in their hearts, found each other and fell in love.
They have a burning desire to experience their "first time" together before their eternal rest... But they don't know how.
The two haunting spirits enlist Yuna to help them foster more "Yuri" couples at school, to help girls struggling with their hidden feelings, and in the hopes that her successes will help them gather the information they need.
