Three weeks after the events of Rainbow Rocks, the sirens are desperate. Without their hearts—the jewels that hold their magic—they have no power. They can't sing, can't manipulate people, and worst of all, can't feed. Their only hope is to restore their hearts, and they need to do it soon, before all three of them starve.

The problem is, they're not sure how to fix the hearts. All they've managed to figure out is that they'll need magic to do it, and magic is exactly what they don't have. Scared, starving, and completely out of options, the sirens turn to the last people who would ever want to help them, and the only ones who actually can: the Rainbooms.

After their defeat, Aria is pushing Sonata over and Adagio has finally enough of it.
She decides to give Aria a proper punishment.

NOTE: This story contains corporal punishment and mature language. Reader discretion is advised.
NOTE 2: My native tongue isn't English, it's German. But it should now be decent English, because a good American friend called Desparil was so kind to help me with this story.

When the Rainbooms lose the Battle of the Bands to the Dazzlings, Sunset Shimmer finds herself to be the most hated person at Canterlot High yet again. With Twilight Sparkle missing and no one left standing to reunite the Rainbooms, Sunset and her few remaining friends must discover a way to bring down the tyrannical trio without falling under their spell.

It has been weeks since the defeat of the Dazzlings, and Sunset Shimmer's friendships have only gotten stronger. Whilst finally relaxing in the times of peace, Sunset discovers an old enemy: Sonata Dusk. Strangely alone and apparently homeless, Sonata's luck seems to be at its all time low.
Seeing a little of herself in the former siren, Sunset embarks on a mission to help Sonata find friendship.

Aria Blaze enters a low-grade singing competition in order to gain its audience's hatred and reassure to herself that she's lost her singing voice forever, but fate has different plans when she comes across a Sapphire Shores who wants to prove that she has the skills to teach absolutely anyone how to sing.

Are there times you've ever wondered, "Jee, why did the girls at Canterlot High forgive Sunset Shimmer for her evil succubus meddling so easily?"

The answer's simple: "Because, deep down, she's a pretty pretty pony, you stupid melon fudges!"

Of all the creatures in Equestria, none are more in tune with the magic of music than the seaponies. Everything about their culture is built around it. But what happens when a seapony doesn't have that connection to song that defines them? How far would they go to find acceptance from those around them?

Deserted by her adoring fans and powerless, Adagio Dazzle sits alone in a cafe. Abandoned by her fellow sirens and coming to the realization of everything she's lost, she finds herself losing hope...

Until she is joined by a complete stranger. One who claims that he has heard her sing... and adores her, almost as if her spell were still holding sway over him. Impossible? Yes. But at this point of desperation, Adagio is willing to believe in miracles.

Could he be her last chance to regain her powers?

*Spoilers in the comments, enter at your own risk*

Defeated by the Rainbooms, Aria and Adagio finally have enough of Sonata Dusk, and banish her from the group with some incredibly harsh words.

Broken and remorseful of her actions, Sonata sits alone at a cafe, wondering what to do with her life. It is there that she meets a boy who might be able to help her. A boy who might allow her to redeem herself for her actions with the Dazzlings.

A boy who kind of resembles one of her former rivals.

Just some silly shipping that I dreamed up because I honestly can't think of anything else. Seriously, writer's block is baaaad.

Also, Dusk Shine X Sonata Dusk = DuskDusk OTP. Don't deny it.

Seriously. Just try to think of a better ship name than DuskDusk. I dare you.

Also, I totally made a group for it. For realzies.

The dazzlings: Adagio Dazzle, Sonata Dusk, and Aria Blaze have been defeated in the battle of bands. They are broken and with no mode of sustaining themselves until Adagio sees Sunset's magic book....
