While following Kanan on her morning run, the girls overhear an awkward conversation between her and Mari. The next day, as Kanan returns to school, Chika becomes sick of everyone arguing and tries to confront her, Dia, and Mari about what really happened. While Kanan remains defiant, Dia reveals to the others that during the Tokyo event, Kanan chose not to sing on purpose because she didn't want an injury Mari had to get worse by performing, further revealing that she quit being an idol to stop Mari squandering so many possibilities for her future. Hearing about all of this, Mari properly confronts Kanan, and the two finally manage to make up with each other, after which both of them become members of Aqours alongside Dia, who is revealed to be the one who came up with the group's name.
