He starts talking to her and they become friends, but the next day, Toyo surprises him by saying that she is the one who killed the woman and surrenders to the police.
The wildly popular Hancho series returns to television for a 6th season! This time, the setting moves to the foot of Tokyo’s newest landmark, the Sky Tree tower, in the Oshiage district. There, a new police station has been established, Japan’s first “branch station” of an existing precinct, aiming at a leaner operation free of organizational red tape. The “branch station” promises to serve as a neutral mediator between the main precinct office and neighborhood police boxes and is manned by four detectives, namely, the Azumi unit that so successfully foiled a major terrorist plot through outstanding teamwork six months ago. No sooner is the new branch launched when a tour bus around circling the Sky Tree is hijacked, throwing the Azumi team into the fray with a new slew of crimes in fresh stomping grounds.
