Shimoneta: un mundo aburrido donde el concepto de chistes verdes no existe

During the first few episodes of Shimoneta, thousands of background characters are introduced, the majority consisting of students. Among these students, one in particular seemed to receive a significant amount of attention; a petite brunette who at the time carried no name. In later episodes, due to her sudden popularity amongst fans, she became known as Binkan-chan and was integrated into the supporting cast of characters. "Binkan" is Japanese for "sensitive", most likely referring to Binkan-chan's significant vulnerability and reactions to lewd and sexual images and scenes.
