The Pink (Nadeshiko) member of an idol group currently viral on social media. Known as the personification of "calculated cuteness." Once someone catches her eye, she isn't satisfied until she makes them her fan and drives them crazy for her, regardless of who they originally supported. She tends to go overboard, but knows how to behave in public to avoid causing trouble for the group. Once close to someone, she becomes extremely clingy and makes adorable, selfish requests. Even though people know she's a little devil, they forgive her because of her overwhelming beauty. Her voice is so sweet and addictive it's nicknamed the "Mitarashi Voice." In reality, she is a hard worker who puts in immense effort to perfect her cuteness. She often gets excited talking about cosmetics with Ayano.

The Blue (Rurikon) member of the same group as Renka. She tries to maintain a cool image based on her looks and assigned color, but she is actually a huge fan of idols and cute things; she entered the industry because she admired idols so much. Her maidenly side is completely obvious to other members and core fans. She also works as a model, utilizing her looks and height. She acts very sweet and girlish toward those she trusts. Her room is filled with cute things like idol photos and stuffed animals. She gets pushed around by Renka's selfishness but ends up forgiving her because she's so cute.

The White (Kohaku) member of the same group as Renka. An overwhelmingly beautiful girl with a translucent aura. She loves beauty, cosmetics, and fashion, and never stops self-improving.

She usually finds Renka selfish, but respects her dedication to beauty, fashion, and their work.

The Purple (Fuji) member of the same group as Renka. Contrary to her refined, ladylike appearance, she has a hearty personality; she loves eating, exercising, and sleeping well. She is a master of transformation using makeup, hair styling, and colored contacts, and has apparently taught these skills to the other members. As the group grew, she settled into the "big sister" role. She suffers the most from Renka's free-spirited selfishness, but she seems to enjoy taking care of her anyway.

The Light Blue (Asagi) member of the same group as Renka. The type to completely spoil the people she likes. She appears easygoing and relaxed, but once she develops feelings, she becomes deeply attached. She is the most lenient toward Renka's selfishness and often gets dragged into her pace. She is famous for her "god-tier" fan service and intense eye contact during performances.

The Red (Senko) member of the same group as Renka. An undisputed beauty who is bright, social, and smiles at everyone. She used to work at a cafe, which was reportedly always crowded with customers coming just to see her. She doesn't spoil Renka and scolds her when necessary, but she doesn't dislike her; she watches over her with a fond smile.
