His true identity? A pampered heir to a fortune worth hundreds of billions. Spoiled rotten since childhood by his parents and his top-tier star older siblings, he has a mind that works in mysterious ways. Instead of living the life of a rich second-generation star, all he wants is to start a gang and become its boss! To recruit underlings and claim territory, he kicks open the doors of the nation’s top star-making institution: “Demon Slayer Arts High School.” Watching the trainees in the hallways viciously compete for center positions and debut slots, Inosuke throws his head back and laughs: “Whether it’s Infinity Castle Entertainment or Fujikasane Stardust, I’m taking over this school’s underground scene today!” From then on, this prestigious arts school, dedicated to producing top-tier stars for the entertainment industry, goes completely off the rails: Homeroom teacher Himejima weeps bitterly: “Such promising idols, and they want to become gang bosses instead.” The award-sweeping actor Kokushibo personally joins the cutthroat auditions, determined to crush his retired younger brother Yoriichi in the financial reports. Meanwhile, on the top floor of Infinity Castle Entertainment Group, ultimate capitalist Muzan watches the campus surveillance footage and smashes antiques in despair: “This school is supposed to train idols! Who told him to collect protection money in the studio every day?! Slap an S-rank contract right in his face! Even if we have to package him as a delinquent gangster, he has to debut in the center and make me money!!!”
