Ep. 21: PTA evaluation prompts class 1-C to recruit Akane Serizawa as a substitute teacher
Aired on November 21, 2005

The Parent-Teacher Association intends to assess Becky's instructional capabilities, but she disappears before the inspection can occur. In response to this sudden absence, the female students of Class 1-C urgently search for a suitable replacement to maintain order. They successfully persuade Akane Serizawa, a member of the drama club, to temporarily impersonate Becky. This arrangement allows the school to proceed with the evaluation while the girls manage the situation behind the scenes. The narrative focuses on the immediate logistical challenges faced by the students as they coordinate this deception to ensure the PTA's requirements are met without revealing Becky's whereabouts.
