Plot

At first glance, it looks like an ordinary junior high school. However, it is a horrible black hole where boys are forbidden to urinate. One day, a good and decent boy is suddenly struck by a fierce urge to urinate... The story brings to light the hidden traditions of the school and the history of power struggles among the students, while the boy's lonely and cruel battle is finally described. The verbal and visual shoot-out with its overflowing spirit of parody is noteworthy.
