Flash is seen walking through the hallway of Canterlot enjoying another awesome day with his peers saying hi to some who walk past him and high five one as well, he soon made his way to the music room where he sees the other Rainbooms and the Dazzlings are hanging out and talking to each other. The Rainbooms also have their music instruments as well.

“Hey, girls.” Flash greeted.

“Hey, Flash.” All the girls greeted back.

“I take it you all got a text from Sunset about meeting her here after school?” Flash asked holding up his phone, they all nod.

“I wonder why she needs us here?” Applejack puzzled.

“Maybe she got some new taco recipes to try out.” Sonata guessed squealing.

“Or new brand of cupcakes that I never tried before.” Pinkie said taking out two cupcakes from her hair.

“Not everything is about tacos or cupcakes.” Adagio sighed.

“Can’t believe we have to deal with another Sonata, someone kill me now.” Aria exclaimed as Fluttershy tries to comfort her.

“I’m sure whatever Sunset wants us here has something to do with those machines here.” Rarity pointed at some machines at the corner of the room.

“It’s almost like she’s going to make us her lab rats of something.” Rainbow Dash commented while bouncing a soccer ball on her knees.

“And maybe she’ll wear a sexy lab coat too.” Flash smirked imaging Sunset wearing a lab coat that is open revealing her red bra.

“Can’t you get your mind out of the gutter?” Applejack asked and hiding her blush under her hat.

“Don’t worry, Applejack, I’m sure the Author will give you the chance to mate with Flash.” Pinkie whispered to the cowgirl’s ear causing her to blush even more.

“Hey guys, glad you could come.” Sunset walked into the music room with a clipboard.

“Aw, I was hoping you would be wearing a lab coat.” Flash disappointed a bit.

“I will, just not in the way you’re thinking and is Nevan here?” Sunset asked about the vampire demon.

“Yeah, right here.” Flash put his hand out and enters a demonic swirling aura for a second or two and pulls out the demonic purple guitar Nevan, he throws it in the air and Nevan reform into her humanoid demon form.

“That is so cool, mom!” Sonata amazed.

“Thank you, sweetie.” Nevan smiled.

“Glad you all can make it; I was hoping you guys wouldn’t mind doing a few tests for me on your magic powers and I also wanted to study the demonic energies from Flash and Nevan.” Sunset said as she puts on the lab coat.

“I thought you said in your text that we’ll be rehearsing?” Rainbow Dash confused.

“Well, you are, sort of.” Sunset shrugged.

“Back when I was Princess Celestia's student, I learned best by going out into the field and actually doing something. Studying ancient books is fine for some people, but I like to solve magical mysteries by rolling up my sleeves and getting my hooves... uh, hands dirty.” Sunset explained as she puts on blue rubber gloves.

“I can relate about hard working outdoors, but what the hay does that have to do with music?” Applejack asked.

“I’m trying to figure out how magic works here in this world. Why you girls grow ears, tails, and wings when you pony up and what your instruments have to do with it.” Sunset answered as she plugs in two big outlets together.

“The Rainbooms I can understand that much along with Flash and mom of their demonic energy, but why are we here exactly?” Adagio wondered about she and her sisters being here.

“Well, Nevan told me that she’s been helping you three with your negative feeding on your pendants with her demonic energy.” Sunset said.

“Only a small portion to keep us from getting hungry, but it’s not like we still the demonic energy from her in our bodies.” Aria shrugged.

“Actually, you girls do.” Nevan said confusing the Dazzlings.

“The day after the Battle of the Band, I decided to add my own demonic power into your bodies giving you girls new strength to rely on than the pendants you used to carry around, and I believe it’s time to how you girls are adjusting to that power.” Nevan explained.

“Does that mean we get super awesome powers like yours!” Sonata asked exciting.

“Maybe, I can teach you have to control, but how you use that power is up to you three.” Nevan said.

“Okay, now this is one science lesson that might not bored me after all.” Aria said looking forward to this studying, for once.

“Looks like we’re all set for your science tests, Miss Shimmer.” Flash grinned.

“Great, now let’s get started!” Sunset approached Fluttershy with makeshift helmet she made.

“Uh, are you sure we should be figuring this out?” Fluttershy asked nervously.

“Trust me, it’ll be fun. Just start playing like you always do.” Sunset advised as she puts the helmet on Fluttershy.

“Just be careful, there are some things that even science can’t understand.” Nevan warned.

Fluttershy decided to go with it and start playing her tambourine to make herself happy of playing music as Sunset is checking the readings on the computer showing everything is good, but then the lines on the screen start becoming all wiggly and form a shape of a butterfly. Sunset was shock at this and turns back to Fluttershy ponying up again and the helmet snap off when dozens and dozens of little butterflies came out and suddenly the power went out, and one butterfly came on Sunset’s face.

Moving on to Applejack playing her base floating a few feet above the floor for a few minutes while Sunset is writing some notes on her notepad, but then Applejack suddenly stops glowing and the pony feature disappears. The cowgirl couldn’t understand why it happened and when Sunset try to think of a theory, she got piled by apples falling right on top of her and Applejack simply shrug as she takes one and took a bite out of it. Flash pick one apple one wondering how did Applejack made them in fin air while Sunset pulls her head out groaning in pain a little.

Sunet has Rarity plug in with some wires and giving the fashion girl a thumb up, Rarity starts playing her keytar grace and fun causing her to pony up as Sunset expected. However, what Sunset didn’t realize is that there are the wires around her foot and when Rarity starts to float up, the wires wrap on Sunset’s foot causing her to fall on the floor.

Next up is Pinkie Pie playing her drum set at a normal pace with Sunset looking at the reading on the machine.

“Okay Pinkie, crank it up!” Flash yelled.

Pinkie nods and starts beating the drums harder and faster in her own fun pace causing her pony form to come and glowing pink, when she made a finale slam a dozen balloons came out of the large drum and pushes Sunset crashing on the wall. The balloons have also made Sunset’s hair to become spiked up from being rubbed of electric by the balloons.

“You okay, Sunset?” Sonata asked.

“Peachy.” Sunset groaned as she falls on the floor.

“Never knew science could be this funny.” Aria giggled as Adagio rolls her eyes.

Last of the Rainbooms is Rainbow Dash playing her guitar to show her awesomeness (and perhaps secretly wanted Flash to watch which he is) as Sunset and Flash are inside a sound room record the date on Rainbow Dash’s shredding, everything seems to be okay until the rainbow-haired girl pony up and the magical rainbow colors travel through the wire and into the computer. Sunset and Flash are shock by this and suddenly got splatted with magical rainbow paint on their face.

A few minutes later, Sunset came out to the Rainbooms.

“Finally, after all this testing, I've come to a definitive conclusion!” Sunset said with her hair being all bendy and up like an anime hair style.

“I have no idea how magic works in this world.” Sunset coughed a tiny rainbow from her mouth and feel like her body is about to give out.

“Well, guess we can call it a day.” Flash shrugged.

“Oh no, we won’t!” Sunset said standing up strong.

“Whoa, you recover fast.” Rainbow Dash surprised.

“I still need to check on the demon energies for my research just for a bit and then everyone can go home.” Sunset stated.

“I can go first!” Sonata volunteered.

Sunset soon have Sonata hook up on a couple of wires on her cheeks and some on her body, including two on each of her breasts, and Sunset is at the machine read for the test while Nevan is next to Sonata to help her unlock the demon energy inside.

“Okay Sonata, this part is going to be scary because demon energy is all about the darkness and the other negative things that you are familiar with.” Nevan said.

“Does that mean I will have to think about hatred and fight you guys?” Sonata worried.

“No, my child, you must let the demonic power courses through you like you were born with that power and let it become one with you. Remember, for every darkness there is also light.” Nevan advised with a little kiss on the forehead.

“Now, close your eyes and feel the power inside you.” Nevan instructed.

Sonata took a deep breath and closes her eyes, concentrating harder than she has ever been in her entire life as she didn’t just want to let her mom and sisters down, but not to let herself down too. Then she started to feel something within herself, the dark feeling that is not like hers and figure it must be Nevan’s demonic energy she mentioned and remember the love they share for each other, that feeling is what helped her get in touch with the demonic energy.

Sonata opens her eyes finding herself floating and in her pony up form like back at the battle of the band except the wings are bat-like and the aura is demonic blue.

“I… I did it!” Sonata realized smiling.

“Way to go, Sonata!” Pinkie cheered.

“Hooray!” Sonata cheered too and flew straight with her head stuck in the ceiling.

“Hey, it looks like the rest can do it too.” Flash pointed at Adagio and Aria also in their pony up form with the bat wings and demonic aura of their own colors.

“Probably because we have a strong connection as sisters and shared the same power.” Adagio theorized.

“And we might’ve overheard what mom said to Sonata too.” Aria added.

“Okay, now it’s Flash’s turn.” Sunset plugged Flash with some wires.

“Now, pretend you’re about to be attack by a demon.” Sunset said.

“Okay, here goes.” Flash pulled out the Rebellion sword and channels his demonic power into the sword.

“Here I come!” Flash dashed about five feet forward and thrust his sword downward to the ground and made some large cracks. The release of his demonic energy causes the machine to short circuit a little.

“Mind if I go now, Sunset. I promise Trixie that we would hang out today in a few minutes.” Flash informed as he takes the cup plugs off.

“Sure Flash, can’t keep the Great and Powerful Trixie waiting for what’s about to come.” Sunset grinned and kiss him on the lips for a few seconds.

“Now Nevan, let see how much those lightnings of yours have.” Sunset excited while holding two metal sticks.

“Oh, I think you’ll be in for a big surprise.” Nevan chuckled.

“I kinda wonder if all that power comes from her breasts.” Rainbow Dash muttered, feeling jealous of Nevan’s big melons.

(With Trixie)

Trixie is seen standing outside of store she really likes and looking at the timing of her phone as she waits for Flash to show up for their hang out today, she hopes that dressing up in her causal clothing is okay as she feels nervous about this.

“My god, why am I feeling fluster about this? It’s not like we’re going on a date or anything.” Trixie talked to herself.

“Oh, I don’t know, maybe we could make this a date.” Flash said behind Trixie making her spook a bit.

“Flash, I’m so glad you make it!” Trixie hugged Flash, then she realizes the hugging and quickly separate herself from him.

“A-Anyway, this is the place I wanted to show you.” Trixie gestured to the store in front of them.

“The Amazing Magic World.” Flash read the sign.

“This is the store that inspired me to become a great magician, I used to come here all the time when I first came here, and I still do though not as offend as I want.” Trixie explained.

“Wow, very fancy.” Flash commented.

“Come on, I’ll show.” Trixie grabbed Flash’s hand and they enter the store.

Inside Flash can see all sorts of magicians’ stuff everywhere like the classic top hats, the black stich wands, the wardrobe like a suit and the sexy bunny outfit, even some magic kits too.

“This place looks good.” Flash complimented.

“Indeed, every time I come here this always bring back some memories and help me feel at ease when I’m a little stress.” Trixie mentioned.

“Well, if you need some help with stress then maybe I can help you with that.” Flash walked up close to Trixie’s face with their nose being very close to each other which causes her cheeks to blush.

“Looks like you found yourself a man, Trixie.” A man said at the register.

“Oh Rodin, this here is my, huh… friend from school, Flash Sentry.” Trixie introduced a little nervous.

“Friend, huh? Didn’t look like that to me just a few seconds ago.” Rodin teased.

“I’m the owner of their store and been in this town for a long time, since to finally meet the Devil hunting boy I heard so much about.” Rodin said extending his hand to Flash.

“Nice to meet you too, I don’t think I ever came here but I can tell certainly feels magical in its own way.” Flash said shaking Rodin’s hands.

“Glad you approve, just let me know if you need anything from me and I’ll see what I can do.” Rodin offered.

“I’ll be sure to think about that.” Flash said. He’s not sure why, but he is getting a strange feeling about this guy that he is normal yet not normal at the same time.

“Hey Trixie, mind if we go outside. There’s something I wanted to talk to you in private.” Flash asked.

“Sure, it was nice seeing you again, Rodin.” Trixie said as they walk out of the store.

“Well, Descendant of Sparda, you’ll be seeing me more than you realize.” Rodin moved his sunglasses down a little showing his eyes glowing red a little.

Once they are outside of the magic store, Flash suddenly carry Trixie up in his arms bride style and jumps high on the outer wall and jump again to the rooftop, Trixie is blushing made as this is the time first, she has been carried like this in her life. Flash gentle sat Trixie down and looks deeply into her eyes which made her blush like before.

“So, what is it you want to talk about?” Trixie asked.

“Well, I was just wondering you would consider becoming my second girlfriend.” Flash revealed.

“Wh-What? Second Girlfriend?!” Trixie gasped.

“And before you ask. Sunset and I already talked about this and decided to make our relationship an open one, meaning I can have as many girlfriends as I want on her approval first and we decided you to join in.” Flash explained.

“…I see, so you also have feelings for the Great and Powerful Trixie?” Trixie asked smiling.

“Yeah, your passion for your dreams is cool and determine to make it come true. Plus, you’re very cute when you used to talk as a third person.” Flash confessed.

“Well, in that case. The Great and Powerful Trixie will gladly be your girlfriend.” Trixie declared wrapping her arms around his neck. And the two kiss each other just as sunset came.

KO a new chapter is done and hope you all enjoy it!

Well, Sunset went through all sorts of tests to check on everyone’s powers and so far, she couldn’t find anything on the magic of the Rainbooms and will probably learn that demon powers aren’t so readable too. And now, Flash has gotten his second girlfriend being Trixie confessing his feelings to her and Trixie responded with a self-declaration and a kiss to end the day.
