The girls' class has to decide on a class representative for the second semester. The first semester class representative, Tachibana Mamiko, instantly raises her hand as a candidate. However, the entire class is in a state of unease. The reason? Mamiko is a quick to nag and really strict class representative who is feared and called Nag-iko. Everyone thinks her continuing as class representative spells trouble. Suddenly, Saotome nominates Ringo for class representative; a move that surprises Ringo. Ringo claims her being class rep is impossible, but the class is so excited that they won't listen to her. Seeing the situation, Mr. Atsui proposes to let Ringo be class rep for three days as a test.
