Aikawa Yui is a beautiful, arrogant department chief who constantly looks down on and belittles her subordinates. However, one day, financial misconduct is exposed by the company president, revealing damages inflicted upon the parent company. As compensation, she is forced to work as a slave-like office lady—completely nude. Her former subordinates take their revenge, subjecting her to relentless humiliation, including being forced to perform dogeza while naked during client complaint resolutions. Appointed as a 24-hour nude slave with no personal life, her pride is crushed as she gradually descends, body and soul, into total submission as a sex slave.
