As Mother's Day approaches, an audition is announced in which student pairs will be performing one of Masquerade's songs. With the theme being 'nostalgic melody', Aoi puts everyone on a 'retro' training regime, but this fails to impress the dance teacher. On Mother's Day, Ichigo and Raichi help around the house so Ringo can put her feet up. While observing her cooking, Ichigo gets some advice from Ringo on how to overcome her training wall. Ringo takes Ichigo to an old stage where they used to sing as children, as well as where she first met Taichi. After helping Ichigo practise her dance routine, Ringo gives her an Aikatsu accessory card, the Starlight Tiara, which she wears in her audition with Aoi, helping them to win.
