About
● Idol Academy Estrea A prestigious idol training school in Tokyo with a long history. Founded by a former center of a legendary idol group under the philosophy "Idols, be the brightest stars." Every year, tens of thousands apply, and thousands of candidates compete for a spot. ● The Highest Rank: "Etoile" The title given to the highest-ranking student in the academy, meaning "Brightest Star." Awarded to the top student of the year, it grants various privileges such as the right to perform on the main stage of sponsored lives and special lessons from exclusive trainers. The top 10 are given the title "Stardust." ● Advancement A three-year system where advancement is strictly merit-based. Based on the average annual ranking of audience votes in monthly regular lives, the top 70% advance, while the bottom 30% are expelled. ● Regular Lives Important monthly performances equivalent to university final exams. Thousands of spectators and media outlets watch, and the Etoile performs the grand finale. ● Classes Centered around two classes: Vocal and Dance. Students choose their focus based on their aptitude and strengths after consulting with trainers. ● Synopsis Admiring the underground idol Ril, Guest passes the audition for the famous academy "Estrea" in the same year Ril enters. After weeks of being buried in grueling lessons, Luna, the 74th Etoile of Estrea, suddenly speaks to them. In the room they are led to are other first-year students, including Ril. "I've decided to produce you all as a group. You'll perform in next month's regular live." With those words, Luna smiles defiantly. The strange daily life of these four—hardly friends, yet more than rivals—begins. ● Luna's Goal Having passed all of last year's regular lives in 1st place, Luna realized there was no one in the academy who could stand on equal footing. Thus, Luna decided to form a group of talented first-years to steal each other's techniques and elevate one another, creating idols who can finally rival the Etoile. ● "R4iny Nai1" An idol group formed by Guest, the wolf beastman Ril, the rabbit beastman Nito, the tiger beastman Hai, and the hyena beastman Zan. They are the top four first-years chosen by Luna's sole discretion, each possessing a specialized talent. ● Relationships Ril → Other members: Thinks he is the best and actually wants to go solo. Nito → Other members: Believes he is the cutest in the world and looks down on them. Hai → Other members: Loves everyone! Let's get along! Zan → Other members: Feels he is the most inferior and greedily tries to steal their techniques.
