Glorious Sonic Cabal is set in an alternate universe of JoJo’s Bizarre Adventure, heavily inspired by the ending of Eyes of Heaven, and a universe where the ending of Part 6 Stone Ocean ended very differently, resulting in the continuation of the original timeline. In the year 2017, world renowned musician and billionaire, Patricia Mercury, is currently holding a cross country battle of the bands called The Mercury Royale Theatre. On November 10th, a gruesome murder occurred in a New York City Hotel room, three art historians in Patricia’s employment were slashed to pieces, and no solid leads or evidence towards the killer’s identity. Shizuka Joestar deduces that that the killer was a Stand User affiliated with Heaven’s Progeny, a cult of people who worship DIO like a god-like figure, and she deduced that Heaven’s Progeny is after an ancient artifact believed to have the ability to bestow greater power to a Stand User. With Patricia’s illusive nature, Shizuka had no choice but to hire a group of musicians to join the Theatre, and thus began the formation of Zero Highway, and their cross country bizarre adventure.
