Rainbow

Rainbow (虹) is the third episode of the ''Love Live! Sunshine!! Season 2'' anime series. It was aired on October 21, 2017.

Summary
Mari gets a call explaining that, due to the rain, the school open house is getting pushed back a week, which causes the open house to fall on the same Sunday as the Love Live! qualifiers. In order to perform at both, Dia explains that Aqours must be the first to perform at the Love Live! qualifiers so that they may rush back to the school. However, the order of group performance in the qualifiers is decided by lottery, and the group ends up being the 24th group to perform. Riko suggests that the girls split up, with Chika, You, Riko, Ruby, and Dia performing at the qualifiers, and Mari, Kanan, Hanamaru, and Yoshiko performing at the open house.

Chika, You, Riko, Ruby, and Dia find themselves on stage at the preliminaries, hesitant to perform. Then, off-stage, the rest of the girls call for their attention and explain that they came to the preliminaries instead of the open house as they feel it would be better if the entire group performed together. Aqours, reunited, then performs MY Mai☆TONIGHT. After the show, Chika leads the rest of Aqours to an orange grove, explaining that they could take a small orange transport vehicle to the open house. The group makes it to the open house just in time, and the episode closes with Aqours performing Kimi no Kokoro wa Kagayaiteru kai?.
