Starring Sadao Abe and written by Kankuro Kudo, a hopeless Showa-era old man time-slips again! It is back! A low-awareness time-slip comedy!! The Friday drama "Extremely Inappropriate!" aired on TBS in the January 2024 season returns as a special drama in January 2026! In the Friday drama "Extremely Inappropriate!," Ichiro Ogawa, a junior high school PE teacher and Showa-era middle-aged man played by Sadao Abe, accidentally time-slips from 1986 to the present day of 2024 and unleashes compliance-ignoring remarks that are considered "inappropriate" in the Reiwa era. It is a low-awareness time-slip comedy that gives people in Reiwa, bound by compliance, a chance to think. Rather than judging whether Showa or Reiwa is right, it depicts people who live earnestly in any era, always valuing family and work. In the final episode of the series drama, the time machine bus becomes unusable, and Ichiro returns to the Showa era. Then Professor Inoue appears before Ichiro from the future and invites him into a time tunnel, saying, "Let's go to any era you like!" The special drama depicts what happens after the series drama. Will Ichiro, the Showa-era middle-aged man who can now go to any era he likes, stir people up again with inappropriate remarks in the time he time-slips to!? The 93 minutes of bonus video contains a production announcement press conference, the complete edition of "Maruwakari SP," a collection of crank-up footage, and a PR collection. A special booklet (eight pages) is enclosed.
