For April Fool's in 2023, both the Kamiyama High School and the Miyamasuzaka Girls Academy have been replaced with a single academy, the All Music MIKUdemy and its headmaster is Mikudayo! The characters have also all been shuffled into 4 different classes. Alongside this change, new area conversation have been introduced and the virtual singers have been let into Shibuya? once more. Unlike last year, instead of covers, all characters now sing in the song Be The MUSIC! by kinoshita.
