She worked as an accountant before her life fell apart. Suddenly arrested and convicted of embezzlement, she's sentenced to a year in Black Wing prison under prisoner number 3077.
An orphan—both her parents died in an accident—she's largely isolated except for her boyfriend Yakumo Kiyonori, who's become her emotional anchor. Being the only woman in a male-dominated prison is already brutal enough, but things get far worse when Aki Myoujin starts systematically breaking her down, both psychologically and physically.
