There were delinquent students at Fukuoka Mentai High School.
They were known as class-skippers, and more often they were on the rooftop killing their time than a sitting in the class. Finally, teachers took action trying to convince them,
but their efforts were close to nothing.
Then the delinquents took out cigarette to smoke.
At the moment, Onara Goro appeared and out of blue,
began to explain about the mechanism of the fart.
As a result, strangely, delinquents were deeply moved by the story and mended their ways.
