Adagio's pov

We are eating cupcakes at cupcakery. I'm eating a red strawberry cupcake, sonata has a marshmallow cupcake, Aria bought a carrot cupcake, and Mackenzie ordered a lovely blueberry cupcake. We are talking about our next plot twist.

"This cupcake is so delish!" Sonata exclaimed while taking a big bite of her food. Aria rolled her eyes.

"Mac, we need you a lot for the next part of the plan." I said to Mackenzie, who ignored Aria and sonata.

"Ok, so what do you need me for." Mac asked.

"Do you have 4 rubies? It's really important." I said lowering my voice so no one can hear us.

"Yes, but why?" Mackenzie asked, curiously.

"You'll find out." I replied mysteriously.

After finishing our cupcakes, we went to Mackenzie's house where we can discuss privately.

Mackenzie handed me the 4 rubies that I requested. I examined them carefully.

"Good!" I said with satisfactory. "Now let's go to your backyard cause we need space."

Mackenzie nodded and we all went to the backyard.

"Just copy us. Follow my lead." I told Mackenzie.

I put the MTAC at the center and Aria and sonata placed the rubies around it. We stood beside the rubies and hold our hands together.

"Mackenzie, before we do this, do you promice to stay loyal to us whatever happends?" I asked Mackenzie hopefully.

"Yes! Even if I have to be siren." She said confidently.

"Good! Cause your going to be a siren." I said to her with a smirk. She panicked but it's too late to turn back so I hold her tightly.

Aria, sonata and I chanted a special spell then pain spread to our body.

"Ahhhhhhhhhhhh!" Mackenzie screamed in pain.

Our Vission darkens and our breathing lessens. I remember the last time this happend to us and I know that this will be worth it.

After a moment, we all collapsed. I touched my neck, sure enough, there was a ruby necklace that holds our dark powers. I smiled. Our magic is back!

I looked at my sisters, I can sense that they are happy that they finally have their magic back.

I looked at Mackenzie, she is still a bit weak so I helped her to sit up. She touched her neck and gasped. She is probably surprised to have a ruby pendant which means........

.........she is the 4th siren.

"I-I a-am a siren?" She asked me in a weak voice.

"Yes. You are one of us now." I replied. "And there is no turning back."

"You can give Nikki your revenge now. And you will succeed because of your new powers." Aria reminded her.

"Yeah! Show her that you're boss!" Sonata exclaimed.

"You're all right!" Mackenzie said evily. Suddenly, her weakness is gone she stood up and smirked. "Maxwell, here comes your punishment for stealing my glory!"

"Yeah, but first let's see if it works. Let's try to sing then hypnotize anyone." I announced.

So we all went to the street and when a random guy passed near us we all sang together.

"Ohhhhhhh! You're under our spell" we sang.

The guy froze and turned to us. His eyes turn green. Yes! He is under our spell! The pendant works!

We all excitedly smiled at each other.

"This is going to be fun!" I exclaimed.
