Princess-Session Orchestra

Princess-Session Orchestra centers on Alicepia Channel, a glittering video-sharing space where girls upload singing, makeup, and dance performances, and on Alicepia itself, the hidden country tied to it. Time moves more slowly in Alicepia than in the real world, allowing its users to sink deeper into music, idols, and fantasy. For Minamo Sorano and her best friend Natsu Hinomoto, that world is more than entertainment: it is where they watch the princess idol Kagari Shirube perform live and hold onto a dream that feels far beyond ordinary life. That dream changes when monsters called Jamaocks attack Shirube's concert and throw the audience into panic, exposing how fragile Alicepia's peace has become. The crisis reveals that only princesses who keep a song in their hearts can fight the Jamaocks and protect the realm from collapse. Drawn into Alicepia's defense, Minamo stands alongside Kagari Shirube and Nagase Ichijou in a conflict where performance and battle are inseparable, and where friendship and unwavering resolve matter as much as raw talent. Across the franchise, the struggle to save Alicepia turns its musical wonderland into a larger fight to preserve hope, harmony, and the fantasy that define the realm.
