(Voiced by Sayaka Senbongi, known for Haru from Beastars and Kikuri from Bocchi the Rock). Aged 15 (at the start of the story), 178cm tall, and the protagonist of our story! She's an aspirant at the Kouka School who stands out of among the rest of the Kouka students, and not just because she's the tallest student in the school. She dreams of playing Lady Oscar one day and strives to aim for the top.

Sarasa has a bubbly personality, being friendly towards those who cross her path and openly affectionate of those she's close with. However sometimes her brashness can sometimes stray into being inadvertently tactless. She's a big fan of anime, manga, and period dramas, and she's always ready with an anime reference in any conversation.

While learning Japanese dance at the Shirakawa household, She aspired to become a kabuki actor, not knowing that kabuki is an all-male form of theatre, and was eventually forced to give up her childhood dream when faced with that reality. She hadn't studied vocal music and ballet for long before entering Kouka, but she made up for her lack of experience with an innate ability to copy other performer's gestures perfectly, using the fundamentals she's developed through Japanese dance as a tool to forge her future.

(Voiced by Yumiri Hanamiori, known for Shin Sato from Cinderella Girls and Ryuji Ayukawa from Blue Period) Aged 16. Nicknamed "Naracchi." She is a former idol who is expelled from her group because of her trust issues with men and she applied at the Kouka School to escape her past. She suffers from androphobia due to childhood trauma.

Ai always had a strained relationship with her mother while growing up, who treated Ai like a burden. Ai withdrew into herself, becoming apathetic and skipping school. Only her uncle seemed to care, and once she confided in him, he took her under his wing. The lingering influence of her trauma means she continues to keep to herself and tries to not get involved with others, a subconscious attempt to protect herself from further harm.

While out, she always wears a face-mask and avoids wandering, abiding by the social rules of any given situation to minimize her interactions with others. She joined JPX because it's an all-female group, while holding no real interest in idols or idol-culture, not realizing she'd have to personally interact with the male fans. After being forced to graduate, she joined Kouka Academy because of the exclusion of male performers and the primarily female fanbase. Over the course of the story she learns to lower her walls to others and develops a deep-felt passion for stage acting.

(Voiced by Sumire Uesaka, known for Anastasia from Cinderella Girls and Lum from the Urusei Yatsura remake) Aged 16. She is the class representative of the Centennial Class. Being a huge Kouka fan (a Kouka nerd, otaku if you will) she enrolls at the Kouka School, skipping her chance to become a prima ballerina.

Sawa is a calm and dependable committee chairperson who passed the entrance examination with the top score. With her steadfast and diligent personality, she makes for a strong class leader and keeps her composure in most situations, except when it comes to Kouka-related issues (to the point of getting a nosebleed when seeing a top star in person).

(Voiced by Riko Sasaki, known for Daia from Kiratto Pri☆Chan) Aged 16. Nicknamed "Aya." She's timid, shy, and plagued with anxiety over her weight. She almost quit the school due to the pressure. Despite that, she is one of the most talented performers in the Centennial Class.

She is arguably the best singer in her class, but isn't very confident in herself, considering that many of her classmates have trained all their lives to be on stage (e.g. Sawa's family running a ballet studio, Sarasa doing kabuki as a child, and Kaoru being a third-generation Kouka applicant). She worries about a difference in abilities compared to her classmates.

(Voiced by You Taichi, known for Ayanami from Azur Lane and Hephaestion from Fate/Grand Order) Aged 18. She is the daughter of a second-generation Kouka actress. Unlike her grandmother and mother, who played female roles as musumeyaku at Kouka Revue, she aspires to play male roles as an otokuyaku. She auditioned for Kouka three years in a row until finally being accepted during her third-year of high school. Because of her repeated attempts to get in and her esteemed family background, she works extra hard to prove herself, striving to maintain a higher level of professionalism than her peers.

She takes her training as a Kouka student very seriously, to the point of scolding her classmates for letting themselves get tanned during the summer instead of taking care of their skin, and snapping at suggestions that might tarnish the prestigious image of Kouka academy.

(Voiced by real-life twin sisters Satsumi and Risae Matsuda, known for Hoshi Shouko from Cinderlla Girls and Hakumei from Hakumei to Mikochi respectively) Aged 16. They've been inseparable since birth, in-sync with everything, including their hopes and dreams. This is in spite of their differing personalities, with Chiaki being energetic and outgoing while Chika is reserved and introverted.

Inspired by the bunny lady twins they saw in a Kouka performance, they auditioned for Kouka together, but initially only Chika was accepted. This devastated Chiaki, so much that she didn't leave her room for three days. To console her sister, Chika decided to defer her admission to Kouka so they could try again the next year. This becomes a source of resentment from Chika towards her sister, as it was a major sacrifice and significant risk, since there's no guarantee they would accept her or Chiaki on their second try.
