Yamegoku - I Will Quit Yakuza(2015)

Nagamitsu Bakushu is a mysterious police officer who mans a hotline within the Tokyo Metropolitan Police’s Organised Crime Department for breakaway yakuza members. After receiving a phone call, the detective in charge has to make contact with the yakuza, protect him, fix things up with the organised crime group which the yakuza belongs to, and finally place the yakuza in a respectable occupation. Although Bakushu ended up supporting the rehabilitation of yakuzas, she somehow treats them like enemies and gets the people around her involved.
