BanG Dream! Episode Rating Graph

RAS and Roselia prepare for the band battle that is held at Dub Live House. Despite Roselia preparing for the "Over the Future" concert, a precursor event to FUTURE WORLD FES, Yukina still wants to perform with RAS as soon as possible. Sayo leaves, believing that Roselia are overloading themselves practicing for two events at once. However, after talking to CHU2 and finding out why she wanted to set up RAS, Sayo comes back, intent on beating them. On the night of the band battle, RAS and Roselia perform. Announcing the verdict after the performances, RAS wins the band battle with CHU2 exclaiming that RAS is better than Roselia.

Reeling after their defeat to RAS in the band battle, Roselia reflect upon their performance and prepare for the "Over the Future" concert. Sayo practices intensely for the concert but collapses during a break from practice due to overwork and fever. Sayo recuperates in her bedroom with Hina and the other Roselia members visiting and preparing a meal for her. Yukina chats with Sayo about why she accepted CHU2's band battle challenge: to learn something from other bands such as RAS in order to grow as a band. After Sayo recovers and doing one last practice session, Roselia performs in the "Over the Future" concert. Yukina thanks the fans for their ongoing support before starting their performance.

All the old shopkeepers from the Jizo-dori shopping district break their backs just before their trip to the hot springs, so everyone (except PAREO and CHU2) go in their place. After settling into their rooms, the characters from different bands interact and socialize with each other. In particular, Rei and Kasumi meet, where they praise each other's performances as RAS and Poppin'Party respectively. Some of the characters also rest in the hot springs with some staying on for too long, resulting in them overheating. In the end, Afterglow inform Kasumi and the others that Poppin'Party's music video gained over 10,000 views which they celebrate before tending to the overheated characters.

After Masking leaves the impromptu RAS meeting, Rokka looks for her but to no avail. The next day, after receiving advice from Kasumi, Rokka searches for Masking again, finally finding her in her school. Meeting in front of the Budokan, Rokka praises Masking for helping her and tells her to meet with CHU2 to make up which Masking initially becomes hesitant before agreeing. Meanwhile, Rei meets Tae where she talks to her whether she still cares about RAS; Tae tells her that as the vocalist of RAS, she has the power to change what RAS will do in the future. RAS (sans PAREO) reunite as a band to perform, but feel anxious and distracted due to PAREO's absence and do not perform well. While Rokka and Masking head to Chiba to find PAREO, Rei talks to CHU2 about needing to work together in the best interests of the band. After finding out that CHU2 wrote off PAREO for being useless, Rei and CHU2 also head out together to find her.

After not performing in RAS' encore, Rokka is chased by CHU2 and PAREO in school and around town the next day, wanting to scout her for RAS. In the meantime, CHU2 meets with Yukina, reiterating her challenge to Roselia. Seeing similarities in the bands' philosophies, Yukina decides to have Roselia enter in the BanG Dream! Girls Band Challenge competition. Later in the night, after seeing Rokka practice her guitar in the Galaxy live house, Masking takes Rokka to CHU2's studio, where she performs alongside RAS. Unimpressed with Rokka's lackluster performance, CHU2 decides not to include her in RAS, explaining she cannot accept those withholding their skills to satisfy her.

The preliminaries for the BanG Dream! Girls Band Challenge begin with the top two teams in vote count going to the finals at the Budokan. Roselia and RAS begin performing their live shows while a zoned-out Rokka comes to terms with her failed RAS audition. Meanwhile, Poppin'Party write a new song for their first live show in the preliminaries which they perform in front of a live audience and Rokka. Motivated by Poppin'Party's new song, Rokka quickly rushes to RAS' studio where she is given one last chance to audition. Impressed by Rokka's passionate performance, CHU2 adds her as a (temporary) guitarist, ordering Rokka to become a guitarist worthy of RAS.

Inspired by RAISE A SUILEN's music video (MV), Poppin'Party decide to make a MV of their own (dubbed PoPi-V). Taking cues from Pastel＊Palettes' MV and Rokka's ideas, Poppin'Party take random photos and videos with Rimi and Arisa putting the video together. After many sleepless days and nights, Poppin'Party are amazed by the MV they produced. They nervously upload the MV on the competition website but are excited by the likes they receive straight away. Later in the night, CHU2 confronts Roselia and proposes a band battle with RAS, which Yukina accepts.

Hoping to gain more votes, Poppin'Party plan a three-week schedule of live performances. In addition to Galaxy, they play at CiRCLE and Dub alongside Roselia and RAS respectively. Despite having fewer votes than both bands, they enjoy their newly-gained momentum as they reach sixth in the polls. Although RAS offer their support to Poppin'Party, including baking a cake for Tae's birthday, they fall behind Roselia in the voting. In response, CHU2 calls an impromptu meeting in which she announces that RAS will play in other venues to force other bands to withdraw. She also takes control of everyone's calendars and instructs the band members to follow her orders and to not socialize with other bands. After an argument where CHU2 questions everyone's commitment to RAS, an incensed Masking walks away. PAREO attempts to console CHU2 but is harshly criticized as being useless.
