Aikatsu Friends!

During the spring break preceding her second year in junior high school, a regular division student named Aine Yūki encounters the top idol, Mio Minato. With her great talent to make friends, Aine easily befriends Mio, having just one request to her: How about performing together on the Aikatsu! stage.

Upon transferring to the academy's idol division, Aine happens to belong to the same 'Production' as Mio, being excited to get her very first job from her manager, Tamaki. On her place of work, the top idol unit that is ruling the Aikatsu! world, Love Me Tear's Karen Kamishiro and Mirai Asuka, appear.

Taking dress design up as well, Mio announces the reveal of her Premium Rare Dress in a week. However, she gets the feeling that there is something missing and is not sure about approving the dress' design. Meanwhile, Aine becomes Mio's "one-day apprentice".

With the advice given to her by her production company's stylist, Chiharu, the still idol-egg Aine begins her search for a brand that fits her. Although so many brands are around, it seems neither works.

Wanting people to discover the brand only for her, Sugar Melody, Aine thoughtlessly enters an audition to be the MC in Love Me Tear's event. On the venue, she meets Maika Chōno, an idol who loves festivals.

A senior student named Ema Hinata showed off her leadership skills even at a camp that she went to. However, Mio is not fitting in well with this environment, causing a chain on confusions.
