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"?

On the verge of death, Queen Ophelia wished— "I want to know who killed me." Then, in accordance with an "ancient promise" given only to the owner of the crown, the Fairy King Leah brought her back to life for just ten days! “I died once, so this time I will do whatever I want.” Ophelia's husband, who tried to use her to seize power... her brother, who is unreliable and tends to be swayed by those around him... a knight of the Royal Guard who has fallen in love with her... the list of possible culprits is endless. Who killed the queen?! A royal mystery begins in the palace with a strong slap that will clear the Queen's name before her death! (Source: ComicWalker)
