Synopsis

The story follows Yagami Eiko, a tough detective in the Ueno Central Police Station’s Organized Crime Division. Unafraid to use violence when necessary, she is willing to strike deals with yakuza groups and even the Chinese mafia depending on the situation. Though she frequently clashes with her superiors and colleagues, her results have earned her a certain level of respect within the police force.
 
Behind her relentless drive lies a tragic past; her husband, a freelance writer who fearlessly exposed the underworld, was found dead in a case ruled a suicide. Doubting the official investigation, Yagami Eiko begins to suspect a cover-up. As she digs deeper into the truth buried in darkness, she becomes consumed by a quest for justice – and revenge.
