Kazuko Utsumi

A war widow determined to clear the name of her disgraced husband, who was court-martialed for desertion and executed. Official records have been destroyed, and the ministry that distributes benefits continues to deny her a pension. Twenty-six years after the war, she seeks out four survivors of her husband's garrison. Each tells a dramatically different story about her husband's conduct, but she is determined to learn the truth.

The story revolves around a hardcore Onyanko Club fanatic who decides he wants to kill the girls to prevent the young, cute idols from getting old and married - in a sense, to preserve their youth for eternity.
