| While listening to Happy Around!'s winning song, Photon Maiden's Saki Izumo senses a new, calmer color in their music rather than the usual bright hues. She enters the upcoming remix contest and fails to win, but her track catches Maho's attention; after Saki follows her and is caught, Maho explains although she enjoys the remix, it is too disorganized. Maho expresses surprise at Saki's inexperience with remixing, to which she reveals that Photon Maiden's songs are selected by their producer to align with their persona, though she wants to create her own music.

Later, Muni confides in Rei that she feels guilty for breaking her own promise with Rinku to write each other letters after the latter moved to Africa.

Muni begins by expressing her frustration with Rinku prioritizing her popularity over her, to which Rinku answers she had always kept Muni and the group in mind; when Rinku mentions the broken promise, Muni admits she had stopped writing as the letters made them feel more distanced and was too afraid to apologize; as the song transitions into musical verse, the two confess their desires to reconnect and make amends. |||||

## Reception

Anime News Network reviewer Christopher Farris considered First Mix "as one of [Bushiroad's] best [idol franchises] so far" and that its animation was quite polished, though saying that it did "not [succeed] particularly well" at implementing the technical DJing elements of the show. Anime Feminist author Brock K praised the series' explicit representation of a healthy lesbian relationship between Kokoa and Hayate, as well as Tsubaki's crush on Aoi, while also discussing the nuanced approach of the game's storyline and other characters towards Aoi's exploration of her gender presentation.
