Secret of Smiles.As the idols have some new promotional photos taken, Ichigo, Aoi, and Ran, along with Seira, are asked to help promote a new camera model by letting fans take pictures of them. After running into each other while practising their candid expressions, Ichigo, Aoi, Ran, Seira, and Kii go shopping together to explore the range of expressions they can make, before stopping by Seira's café. There, they discuss how their best smiles naturally come from doing the things they love. After Ichigo and co finish up their performance at the photo session, Seira ponders how it would be nice to stand beside friends on stage.
