Starlight Mayhem is a Friday Night Funkin' mod that runs for two weeks. The Masked Chris created the mod Starlight Mayhem. This week's opponents are two new originals, CJ and Ruby, members of TheMaskedChris' band On Command.
The mod recently received an update called Starlight Mayhem: Rebooted. There are many new features in this update, including CJ and Ruby's new vocals, a new background character, four new songs, and an extra week.
Boyfriend takes Girlfriend on a date to a Starlight Mayhem concert, only to be recognized by CJ, who requests a friendly song battle. After that, he congratulates BF but admits that he wasn't the band's best vocalist anyway. Ruby then runs in, apologizing for being late, but CJ tells her she's just in time and encourages her to sing against Boyfriend despite her shyness. The week concludes with a final duet number in which Boyfriend and Girlfriend (who joins in because she believes a 2v1 battle isn't really fair) compete against CJ and Ruby.
The bonus week has no story, just a friendly little rap battle.
