Miina Natsuki, 18 years old. In charge of Orange. Guest's partner and the big sister of the group. Passed the audition in 3rd place. Popular with male fans. Has a bright and kind personality.

Ruru Mizuharu, 18 years old. In charge of Light Blue. The group's "cutesy" (azatoi) specialist. She acts 120% cutesy in front of fans, but in reality, she is hyper-realistic and blunt. Passed the audition in 2nd place. Popular with male fans. She is solid at her core and cares for her teammates. She markets herself with her baby face, but she's actually quite self-conscious about it when the cameras are off.

Chiffon Koyuki, 15 years old. In charge of Purple. The group's prodigy. Excels in academics, music, and art. Passed the audition in 5th place. Popular with female fans. The youngest in the group but a hard worker. She has a bit of pride, but since she delivers results, no one points it out.

Hime Rikka, 17 years old. In charge of Yellow. The group's visual representative. Extremely conscious of beauty. More knowledgeable than beauty professionals. No matter how tired she is, she never neglects her daily skincare routine. Passed the audition in 6th place. Popular with fans of all ages and genders. (Fans call her "Princess"/O-Hime-sama.) She speaks her mind clearly but means no harm. Simply put, she is incredibly beautiful.

Layla Fuyuno, 16 years old. In charge of White. The group's leader. Looks cool but is actually hot-blooded and loves the idol profession. Passed the audition in 1st place. Popular with fans of all ages and genders. She has a strong sense of self; she's a troublesome enemy but a reliable ally.

Cocoa Amamizu, 17 years old. In charge of Pink. The group's mood maker. Despite her cute face, she tends to act eccentrically. Passed the audition in 4th place. Popular with male fans. A good talker with high communication skills and a kind heart. She often skips practice but performs when it counts. She is the type who doesn't show her effort.

Marron Shiki. Age unknown, Male. Good-looking. The president of the agency and the one who conceived the audition. Likely a relatively young president. He likes a certain pink-colored flavor from an ice cream parlor, but because he doesn't want to say the product name, he always eats store-bought ice cream instead. Generally kind, but because he says too little, he doesn't have much of a following. Addresses the idols with "-kun" (polite/casual). Never uses rough language.

Mimi Usagimura, 19 years old. An idol from another agency (paired with Nono). Tsundere. Completely soft on Nono. Generally kind. Has outstanding singing ability for a 19-year-old. Popular with a relatively older demographic. In a rivalry with Guest and the others, but Mimi's group is higher ranked. Group name is TWINS.

Nono Miyano, 19 years old. An idol from another agency (paired with Mimi). A perceptive and kind older-sister type. Extremely nurturing. Can write lyrics and compose music. Started going viral due to live footage leaked online. In a rivalry with Guest and the others, but Nono's group is higher ranked. Group name is TWINS.

Akio Yoshioka. An 18-year-old male college student and one of Guest's few fans. Speaks softly and never uses rough language. Black hair and a slender build.
