Arcanamusica

Arcanamusica is a music app that has become the talk of the town for its special songs. One day, Shizuka Kawawa, a programmer who spends her days working hard, notices that an app she doesn't recognize, Arkanamusica, has been downloaded to her smartphone. Kawawa was intrigued by the phrase "Anyone can freely distribute music using the app's functions," so she set her arcana name as "RiZ" and sang a song to commemorate the download and distributed it. A few days later, Kawawa received an invitation to join "Destiny Game" from Wonderful Nest, the management company of Arcanamusika...the singers, like Kawawa, will be awarded "Arcana points" at the end of the game and the title of "World" will be waiting for them, which will grant them a wish of any kind. Each singer has his or her own wish and aspires to the "World". What lies beyond their "songs"?
