Brand (ブランド) is the general term that identifies the distinctive product of a company. In the Aikatsu! universe, the term "brand" is used to describe the company in which the Aikatsu Stars! cards are from.
Each brand is based on one of the four idol types: Cute, Cool, Sexy, or Pop and from there create designs with themes and styles unique to that brand. There are currently nine known brands.
Different from the brands from the original Aikatsu! series, in Aikatsu Stars! series, brands are not founded by designers, but instead by "muses", meaning top idols, who represent the spirits of the brands and allow designers to work under the brand project. Only brand muses can wear the premium dresses of that brand.
In the system of Four Star Academy, students who win the S4 Selection match and become a part of S4 can automatically gain the right to found their own brands. Outside the schools, there are also designer companies who voluntarily sponsor idols to do their brands as well.
