Plot
In the year 2035 when the birth rate has dropped dramatically. Schools were forced to closed down due to a lack of applications, dropping all morale and the all-girl Seioh Private High School is no exception. The all-active and positive Manami Amamiya, transfers to Seioh High, often shouting her personal motto to motivate herself to go forward in life. On Manami's first day of school, the lone student council member and secretary Mika Inamori tries to rally students to join the council, but is initially met with an apathetic audience. However, Manami expresses interest in becoming the student council president. To show the school how much she wants to lead the student body, Manami begins to sing Seioh's school song after hearing it for the first time the day before. At the conclusion of the song, Manami is inducted as the student council president and received well by the entire school. The story that follows Manami working with Mika, and three other classmates—Mutsuki Uehara, Mei Etoh, and Momoha Odori—in student council matters, despite Manami and Mika initially being the only official members. After some remodeling of the student council room, Manami and her friends set forth to plan for the upcoming student festival.
