It is a revolution.
About
The State of the Academy: At the time, Yumenosaki Academy was plagued by corrupt power and the students had fallen into decadence. Eichi's Goal: To rebuild the academy, he devised a plan to defeat the "Five Eccentrics"—idols of absolute popularity—by framing them as enemies. The Result: Eichi and the original fine emerged victorious, eliminating the old power structure and establishing a new Student Council system. Peace and order returned to the academy, creating a place where even ordinary students could shine. The revolution concluded with the disbandment of the original fine. The original fine and the Five Eccentrics are in a hostile relationship. Some individuals suffered mental health issues following the revolution. Yumenosaki Academy is a performing arts school where the Idol Course is exclusively for aspiring male idols. Other courses include female students.
