It is now two years later and the girls are just about to graduate from high school. Everyone is reflecting on the past few years at Seioh and are looking toward the future to where they are going. Mika decides to go to America after graduation and study abroad and her friends are there to see her off.
The principal of Seioh High School announces the merger of Seioh and Aikoh High School and the cancellation of the Seioh School Fair. In order to try to change the minds of the administration, Manabi and the student council begin a petition campaign. Later, Manabi returns home to find her brother with his girlfriend, Kyoko Kiyokawa — who happens to be the superintendent of Aikoh High School.
Manami has come down with the mumps and thus cannot attend school for one week. In the meantime, Mika tries to become closer friends with Mei while they try to decide before Manami's return what the theme for the school festival shall be.
The student council plans to release a promo video led by Mei to promote the upcoming school festival. However, Mei soon drops out of the project due to trauma from her past related to being a class representative in elementary school, which left her emotionally scarred.
Manami and Mika start to clean up the student council room but after initially finding it a daunting task, Mutsuki, Momoha, and even Mei help out to turn the room into a café where the students in the school can hang out.
Manami Amamiya transfers to the all-girl Seioh Private High School and arrives with a bang. Before long, Manami is elected the student council president due to her vigorous personality.
The year is 2035 and schools have been suffering due to declining birthrate, having forced many of them to close. An energetic girl named Manami Amamiya transfers to a new school where she quickly becomes the student council president and starts to bring back vigor in the students' lives.
