Unable to meet the quota, he rushes to get a job at the nearby Seitō Sannomiya Private School to apply for a position. He is rejected employment because of his sex, so with the help of his landlady Lulu Sanjō, Hibiki disguises himself as a woman to get the job.

A mysterious voyeur begins to frequently appear on the dormitory property so to keep the girls safe, Hibiki is instructed to temporarily live with them.

Dissatisfied with the long pleated skirts the girls wear during athletics class, Hibiki tries to introduce buruma as an alternative.

It's parents weekend and when it's Hibiki's turn, the parents are asked to join the class. But who will be there for Fūko? Mori and Tofu attempt to enter the school as parents.

The school schedules a physical examination of all students, and suspicious of Hibiki's identity, Vice-principal Reiko Mukogawa makes him take one too.

Hibiki is worried that he's become more of a woman since he's disguised as a woman. A fight starts between the children. But who started it? Meanwhile Tofu and Mori try to dig under the school.

The school's director wants Hibiki to marry his nephew. The students hear about this and decide to spy on his nephew. Can Hibiki stop this marriage in time?

The male students become very unhappy when Shiro Naruo, a friend, is accused of stealing Reiko Mukogawa's salary. They rebel against the school and protest by threatening the safety of a priceless statue in exchange for equal rights.

Fujio Himejima tries to confess her feelings to Akira Fukae with the help of Miho Umeda, but things do not go as planned.

When Hibiki is taken to a hospital to recover from burns the day before, Fūko and Akira visit him. Reiko Mukogawa visits too, hoping to photograph Hibiki out of drag.

Reiko Mukogawa exposes Hibiki's identity with photographs from her visit to the hospital. With this evidence she calls upon the parents and students of the school to promote its change to an all-girls institution. Fūko takes a stand against this and rushes after Hibiki who is shamefully departing from the city.
