Prologue
The royal capital, Capital City, is abuzz with excitement for the biennial Zilvahard Music Festival.
A suspicious shadow slips into the Royal Music Hall, exploiting the briefest lapse in security.
As the divas' voices intertwine and the audience's cheers reach their peak, something goes wrong.
Six ONGEKI Shooters appear through a door of light:
Akari Hoshizaki, Yuzu Fujisawa, Aoi Misumi, Saki Kashiwagi, Arisu Suzushima, and Setsuna Sumeragi.
Ranan and the others find their shooter outfits and stage costumes have been swapped with the newcomers'.
At the same time, the suspicious shadow undergoes a sudden transformation, and the music festival spirals into unprecedented chaos—
