The Ms. Sakuragawa Power-up Operation!

Overview

Sakuragawa-sensei, the homeroom teacher of Class 1-5, looks more nervous than the students before Class Observation Day. To everyone's surprise, her father will also be there to observe the class. Manatsu and the others wonder if he has come to assess Sakuragawa-sensei's ability as a teacher, so Manatsu gets her class together to support their teacher.
