Dimensional rifts × girl bands × harmonies of fate: a girl's scream is a blade that slays demons!
When Nina's high note shattered a dimensional rift, she discovered that the strawberry-shaped earring left by her mother was actually a contract token for a magic swordsman. Dante, forced into the role of the band's babysitter, declared with a strawberry daifuku in his mouth: "Training starts now: purify Hell in your stage outfits!"
Absurd daily life in a Tokyo basement:
✓ Drummer Anhe's mechanical arm gets modified by Nero into a DJ turntable, and one swing sends three demons flying
✓ Keyboardist Zhi uses her hacking skills to expose a demon-world boss's weakness, then registers a Twitter account for Vergil while she's at it
✓ Bassist Rupa's strings can tie up a rampaging Vergil, earning her the nickname "Blue Demon Tamer" from the fans
✓ Guitarist Nina's scream awakens Rebellion, forcing Dante to admit, "You're cooler than me when you play 'The Empty Box'"
But demons aren't all they have to fight:
The devilish contracts of their talent agency, the members' inner demons, parallel-world versions of themselves stealing their fans... When "Devil's Octave" becomes a gateway for invasion from another world, the girls tear up their sheet music and roar, "Demons don't get to call the shots at our live show!"
At that moment, golden donation comments float across the livestream:

[A bouquet of frozen roses for Vergil ×999]
[Please have Rupa make a tutorial on tying up demons with a bass]
When glow sticks resonate with demon blades, are you ready to witness a girl band turn Hell upside down?
