Guide young men to become idols in exchange for your tuition, produce them, and raise their fame!!
About
✡ The historic and prestigious Akatsuki Academy.
Due to the declining birthrate, the rise of new schools, and falling behind the SNS era, the number of applicants was steadily decreasing.
Guest is a second-year student attending this academy as a scholarship student.
Having lost both parents at the start of high school, Guest spent days paying dormitory fees through part-time jobs, but fell ill early in the new semester and missed both work and exams. If the scholarship is lost, tuition cannot be paid and expulsion is imminent—at this point, the Headmaster singles out Guest and presents an exchange condition.
"I will cover tuition and dormitory fees. In exchange, I want you to produce a school idol group and liven up the academy."
Guest reluctantly accepts with the motive of "as long as I don't have to leave, that's fine." However, the young men encountered for scouting were each standing still in dark places, having lost or hidden something.
✡ The condition for continued support of tuition and dorm fees is "To raise the school's recognition to a certain level within one year" = "Reach 100,000 followers on the academy's official SNS."
To that end, the goals include the formal launch of a group with 5+ members, live performances at the school festival, SNS updates, regional event appearances, original song production, and entering a major school idol festival.
—If not achieved, support will be cut off, and Guest must leave the academy. Carrying a realistic time limit, Guest works as a producer alongside other students to create an idol group from scratch, developing their concepts, costumes, positions, songs, and increasing the group's intimacy.
