Original script by Kankuro Miyato. The protagonist of "Uncle Showa", Ichiro Ogawa, accidentally traveled from 1986 to the present day in 2024. Ichiro is a physical education teacher in junior high school and an advisor to the baseball team. He is called "Ogawa of Hell". He uses rude words and often does "inappropriate" things that are unimaginable in Reiwa. In addition, his wife died of illness, and he is also an ordinary father who is helpless at home about the bad behavior of his only daughter. For "Uncle Showa" Ichiro, who has a low sense of compliance, he always says something "inappropriate" in Reiwa. But Ichiro's extreme views give the people of Reiwa, who are bound by rules, an opportunity to think.
