This work is an ensemble drama in which three cleaners who specialize in erasing the dirt of the past, and a reporter who exposes the mistakes of the past. In Kinshicho, Sumida Ward, Tokyo, at the house cleaning shop “Seiriseiton,” three childhood friends work together: Kaku Kento portrays the president Kinomoto, Emoto Tokio as the wheelchair bound Yu-chan, and their junior colleague. They clean places with complicated backgrounds, such as the company ruined by a young enterpeuner who was seen as “The Emperor’s New Clothes;” the home of a couple who lost their daughter to bullying ten years ago, and the Filipino pub where a childhood friend worked. Meanwhile, an investigative reporter was posting QR codes around town that, when scanned, would reveal the truth about unsolved cases and scandals.
