In Chiba, Masking and Rokka search for PAREO by visiting her school. When they show her classmates a photo of her, they learn of PAREO's true identity as Reona Nyūbara. The two spot Reona as she is walking home, prompting her to run away and them to give chase. Upon catching up to her, they learn of her background as an academically successful but meek girl who regularly posts keyboard covers of Pastel＊Palettes songs online. Despite Rokka and Masking's efforts, a disillusioned Reona proclaims PAREO no longer exists until she spots CHU2 and Rei running up to them. After CHU2 asks for forgiveness and is accepted, the band performs a song for her birthday back in the studio. Eventually, the Girls Band Challenge voting closes with Roselia leading, while Poppin'Party and RAS are tied for second.
