Selection Project - Season 1 (2021)

With Suzune and Rena already through, Hiromi, Nagisa, Nodoka and Ao's group are under pressure to get the yells they need before the deadline. While Hiromi wants the group to perfectly replicate an existing choreography, Nagisa clashes with her, saying they need to express their individuality more.

The music team is the last team set to perform, but there's one problem--they aren't set to perform. When Uta wants to get it over with, and Shiori wants to polish her bass line, what's mild Mommy Mako to do?

The second round tasks the girls with performing together in swimsuits, but Suzune is reluctant to wear anything revealing.

As Suzune feels guilt over the donor who gave her their heart, she starts to avoid practice.

As the impending vote leaves everyone conflicted, Rena receives a package from her mother containing a bunch of letters sent to their family, including the one that Suzune wrote. Upon chasing after Rena as she refuses to take part in an interview about the vote, Suzune learns what Rena had discovered; that the heart she received was given to her by Akari following her death.

Feeling guilty over what she said to Suzune, Rena apologizes to her, saying that she got her with her own talent and always wanted to meet the one whose life Akari had saved. In her subsequent interview, Rena states that she does not deserve to stand up on stage, effectively declaring her intention to drop out. After the others give this matter considerate thought, the day of the vote arrives.

To the shock of Sumipanda and the viewing public, the vote ends up as a tie as everyone chooses to vote for themselves, stating that they want to perform as a group of nine. The girls' refusal to vote again results in everyone getting disqualified and the seventh season of Selection Project ending with no winner. In the weeks that follows, the girls meet up during weekends to discuss plans of forming their own group, but Rena takes a backseat role, feeling she does not have a reason to sing.

9-tie begins performing weekly but struggles to get much in the way of an audience.

Just as the girls prepare for the final round, Suzune falls unconscious after she collapses from over exhaustion.

Akari appears in Suzune's dream and they talk about singing.
