The first act is a musical comedy titled “PROM LESSON,” which depicts the struggles of young people and their love affair at prom, a dance party held during the graduation season at an American high school. The musical has two different versions with the same premise but switched, one starring Asami Jun and the other starring Akatsuki Chisei, each playing a different character. In Arthur’s version, the most “tsundere” flower boy in the school, meets a hapless girl who can’t hold her own and gives her lessons to make her the ultimate Prom Queen. The second act is titled Midnight Show “A-EN MOONRISE,” an entertainment show starring the stars in a moon-themed revue.
