Signing Up for a Monster Girl Roommate

"Okay, here is the recite and your 87 cents. Enjoy your new guitar, little amigo." A teenage boy said as he hands a white guitar to a little Mexican boy.

"Gracias." The Mexican boy thanked before walking away with the guitar to his mon who is waiting outside.

"Another satisficed customer, it's nice to see young kids like him taking very interest in music." He smiled.

The teenage boy has blue hair and sapphire blue eyes. He wears a black jacket with a single red and white stripe with a white shirt underneath; it bears a blue shield with a lightning bolt in front, blue jeans and black shoes. He also wears a nametag that show his name "Flash Sentry" so that anyone who comes in can know what to call him.

"Well done, Flash, you certainly are a big help today." A girl said walking to Flash behind the counter.

She has white-light yellowish gray, moderate cobalt blue with brilliant opal stripes, and wears cool-looking shades of gradient from dark purple to moderate heliotrope. She wears a zippered white shirt with blue lines on the shoulders to the short sleeves and at the bottom to the waist area, white skirt that is halfway to the knee with a single black music note, skinny violent pants with pink-purple lighting bolts, blue shoes with a sky-blue stars and white stripe. Breasts sizes: F-cup.

"No problem, Vinyl Scratch, I'm always happy to help." Flash said.

"I was a little worried when Octavia called me that she's wasn't coming because suddenly catching a cold, but then I remember you liking music and I though maybe you would help me with this." Vinyl explained, glad that Flash decided help in the end.

"Well, I certainly do like music when I play my guitar and playing awesome music." Flash bragged and Vinyl rolls her eyes.

"Excuse me, do you have any flutes?" A woman asked.

Flash and Vinyl turn to the woman though she's a bit more, unique because she's not actually not a human woman as she has brown fur all over her body including her face and fur pointy ears on her head and a short doggy tail.

"Hello, ma'am, we have a nice selection of flutes right over there." Flash gestured toward the flute section.

"I'm a bit surprise a Kobold would interest in playing the flute." Vinyl commented.

"Oh no, I'm actually buying one the daughter of my hose family. Her birthday is coming up soon and I wanted to thank her for being such kind girl to me when we first met." The Kobold woman explained, also mentioning the girl loves playing flutes as her favorite instrument.

"Well, I'm sure your love with the flute will be a great birthday present." Flash assured.

"Thanks." The Kobold woman thanked before walking away to the flute section.

"Damn, it's been three years already, hasn't it?" Vinyl asked.

"It sure has, the once normal life we all knew has now become an open world to the demi-humans coexisting with the humans. I'm sure no one had really though something like this could happen." Flash said looking out the window seeing the other monster people or demi-humans as they call themselves walking around the mall with their hosting humans.

"Tell me about, ever since the demi-humans became official citizens of earth things change like getting new music instruments for each different monster to play on." Vinyl pointed out as one section where there are weird-looking instruments.

"I'm glad that we didn't end causing World War 3 when there are others human who don't accept the demi-humans." Flash confessed.

"I know, same can be said for other demi-human who refuses to knowledge humans as their equals, it just shows how stupid these people for not accepting the changes." Vinyl pointed out.

"Amen to that, sister." Flash nodded.

"So, you're doing okay living all by yourself these days?" Vinyl asked.

"Yeah, I'm doing okay with the house and it's been two years since I moved out of my parents' house. Why do you ask?" Flash asked back.

"Then I'm sure you heard about the Interspecies Exchange Program bill." Vinyl mentioned.

"The one about one human or a family letting a demi-human into their home to become a part of their life to increase the bond between two races. I know all that." Flash answered.

"I was thinking maybe you should sign up for that." Vinyl suggested, shocking Flash.

"Seriously, what gave you such an idea like that?" Flash asked.

"Look, Flash, I know you're a good guy and all, but I can tell when someone is feeling lonely even when he's hanging out with friends." Vinyl pointed as she pulls down her shades revealing her moderate cerise eyes.

Flash let out a sigh knowing Vinyl can see right through him like an open book since they've known each for since middle school.

"You got me, every time I come home from work, I always felt like things should be here, but I couldn't figure out what and I'm starting to feel sad about it like there's an empty space in my heart." Flash confessed.

"Which is why I'm telling you to sign up for Interspecies Exchange, it'll change your life for the better and I have a feeling a demi-human will be happy to meet you!" Vinyl said.

"I'm not sure." Flash hesitated at this idea.

"At least give it a thought." Vinyl said before going to check on the other instruments.

(Flash Sentry's House)

Flash just drove his car into the garage and went into his house, looking around to see there are plenty of big spaces for a few people here to hang out at the living room and probably at the kitchen then he looks at the spare guest bedroom he has, though it's just an empty space with nothing inside as Flash didn't bother filling up that room for some reason except for one bed. Maybe it's because deep down he feels there's going to be someone entering his life and move into the house with him, this got Flash thinking about what Vinyl told him about letting a monster person live with him in the house and maybe it won't be a bad thing too.

"I always did wonder what it would be like to have my own monster roommate, seeing everyone else is sharing a demi-human or two in their life I think it'll be good to have one." Flash said to himself as he sat on the couch to some TV.

Finally, he decided to do it and went up to his room, taping on the keyboard of his computer going to the Interspecies Exchange Program website and found the sign in link for the exchange. It's only just a click away for having his life change forever, but that change can also be scary for what if the demi-human he ends up don't want to be friends with him and just hate him for being a human. However, he shook the thoughts off knowing there's no point of worrying about something that you can't do it up close and personally, though he hopes the demi-human is friendly.

"Here goes nothing." Flash pressed the enter button and now the only thing he can do is wait which may take a few days or so.

(The Next Day)

Flash is sitting in his room practicing his guitar while checking the strings to make sure they're not too tight and too light as today is also his day off from his part-time job at the music store in Canterlot Mall, he has been working on a song for a few weeks now is sounds like it's coming together.

DING-DONG

"Umm, I wasn't expecting any visitors today." Flash said before putting the guitar down and walk downstairs to the front door.

He opens the door to see two women in black agent suits and each wearing sunglasses. One woman has very pale spring green skin, pale, and light grayish opal and light gray hair. The second woman light apple greenish gray skin and moderate cobalt blue and light fuchsia hair. Breasts sizes: G-cup.

"Are you Flash Sentry?" The first woman asked.

"That's me, I didn't do anything illegal, have I?" Flash asked a little scared.

"Don't worry, you haven't done wrong. I'm Lyra Heartstrings." Lyra introduced herself as she removes the shades revealing her brilliant gold eyes.

"The name's Sweetie Drop, we're agent of the Interspecies Exchange Program bill. We're here for you about hosting a demi-human." Sweetie Drop revealed as she shows her moderate cyan eyes.

"Whoa, you guys respond fast!" Flash surprised.

"That's how we roll, and we are also your Coordinator!" Lyra added.

"Coordinator?" Flash confused.

"Agent like us who are assigned to the who ones are hosting the demi-humans to make sure they follow the rules of the bill and nothing bad happens between them." Sweetie explained.

"Okay, I think I can understand that but are you guys gonna watch like spy style 24/7?" Flash asked.

"No, don't worry, we'll just be dropping by every now and then to check on you two. Speaking of which, I'll go get Sunset from the car." Lyra said before powerwalking to the black cool-looking car.

"Sunset? Is that the name of the demi-human who is assigned to me?" Flash asked curious, also thinking the name is cute.

"Smart boy, her full name is Sunset Shimmer, and I got to warn you that this is her forth host this." Sweetie mentioned.

"Forth, what happened to the other three hosts she had?" Flash asked.

"I can tell you're a kind boy, so I'm sure you can guess why." Sweetie said with a sad expression.

Flash didn't need to be told of the full story because he can still tell that this Sunset girl must've been kicked out the previous three hosts because of how different she is, probably they called her a freak and couldn't deal with having monsters living under the same roof as them. He hated people who treat others like they're weaker than they are thinking they can do whatever they want as Flash clenches his fist just thinking about punching those bastards in the face right now.

"Don't worry, I promise to give Sunset a happy life and treat like any other person on the planet!" Flash promised with determination in his eyes.

Sweetie Drop was a little surprise by this and smile glad to see a kind young man is willing to give others a chance like some others in the world.

"Glad to hear that." Sweetie Drop approved his spirit.

"Okay, Flash, meet your new demi-human roommate!' Lyra showed the demi-human girl.

This monster girl known as Sunset Shimmer has dark-red skin, sharp teeth with fangs, red and yellow flame-like hair that goes down to her waist, green colored eyes with black in both the out and in the green circle, and two bat-like wings with a hole or two. She wears leather jacket with silver buttons; a raspberry shirt underneath, a skirt with orange, white-yellow, and raspberry stripes, and long black boots with raspberry flames from the foot area to the midway of the boots. Breasts sizes: H-cup.

"(Wow, she's hot!)" Flash thought gasped.

"Hello, as you may already know I'm Sunset Shimmer and I'll be living with you from now. I hope we get along." Sunset greeted and bow to him a little.

"Th-That's cool, I'm Flash Sentry and I look forward to having you here." Flash greeted back a little nervous.

"Oh, looks like someone is hitting on the new girl." Lyra teased.

"What, huh, no, I'm not… we just met!" Flash blushed.

"She's just teasing you, but you should also know that if anything were to happen to Sunset under your watch then you'll be punished. And you should also know that demi-humans are not allow to leave the home they're living in without the host by their side otherwise they'll be force back to their homeland, there is also the rule in the exchange bill that humans and demi-humans cannot hurt each other since the bill is still new." Sweetie Drop explained the rules of the Interspecies Exchange Program bill.

"I heard that they were some demi-humans going around causing trouble." Flash recalled from hearing the news.

"Yeah, and because the law wouldn't allow human law enforcers to deal with them because that would be breaking the bill, but don't worry because we got ways of dealing with them without breaking the law." Lyra explained.

"I'll take your word for it, so shall we get you inside." Flash gestured Sunset to come inside.

"Sure, just let me get my things from the truck." Sunset said walking back to the car.

"I'll help you." Flash offered as he follows her but is stop by Sweetie Drop.

"Just a little warning kid, you better not try anything sexually dirty and forceful on her like a dirty pervert." Sweetie Drop said in a dark scary tone that is scares Flash.

"What Bon Bon mean is that you're not allow to do any sexually activates on Sunset or any other monster girls since they're meant to representing the entire demi-huma race, if you deflowered one like Sunset then you'll arrested on the spot and Sunset will be force back to her home." Lyra explained clearly.

"Oh, well, thanks for clearing that up." Flash calmed down a little but feel scared about being sent to prison if he makes the wrong move.

"Hey, what are you guys talking about?" Sunset asked carrying two luggage.

"Oh, just telling Flash about the rules of the exchange program." Lyra answered cheerfully.

"We'll be going now but expect to see us again soon." Sweetie Drop said walking to the car.

"Wait, Bon Bon?" Flash confused of what Lyra just called her.

"It's a nickname I came up with and the only one allow to call her that, anyway goodbye!" Lyra waved goodbye as she follows Sweetie Drop to the car.

(Later)

"Here's dinner, I hope you like it." Flash handed out the plates of pasta with tomato sauce and meatballs.

"Oh, a classic dish." Sunset commented.

"I hope the room isn't too small for you." Flash said as he sits down.

"It's fine actually, a little bigger than my old room at home." Sunset revealed and eat the pasta which the flavors explodes in her mouth.

"Wow, this is really good!" Sunset complimented as she eats it a little faster.

"Glad you like it, I learned how to make this with my mom before moving out." Flash explained.

"Let me guess, she was sad that you had to leave on your own." Sunset said.

"I take it your parents are like that two?" Flash guessed.

"Yep, they didn't want me to go at first, but I was able to convince them and now here I am." Sunset explained.

Flash felt his phone buzzing off in his pocket and took it out, he gasps upon seeing the text mission.

"No way, I didn't think it would arrive sooner than I thought!" Flash excited.

"What is it?" Sunset asked.

"Just wait right here, I'll be back from the mall!" Flash ran out to his car and drove.

"The mall, but don't they close at this hour?" Sunset asked.

Sunset decided to wait for Flash after she finish her dinner and sat on the couch while watching some TV, it's only been over 40 minutes since Flash left and she is starting to worry if he has abandoned her like the others have because of being a "monster" that most see her and the others.

"Hey, Sunset." Flash entered the house, surprising Sunset that he came back just like he said he would and revealed a red guitar with flame design on the front and wings almost like hers on the side.

"Wow, is that for me?" Sunset asked.

"Yeah, I saved some money to get this devilish guitar and I thought this would be a great welcome present for you." Flash explained as he hands the guitar to Sunset.

Sunset shock upon seeing such kindness from one human boy when the others she met didn't show anything like this, only fear and little hate and she was almost accused for something she didn't do.

In respond to this kindness, she hugs Flash surprising him.

"Thank you!" Sunset thanked softly. Flash smiles and return the hug with a "you're welcome" response.

"So, think you know how to play?" Flash asked curious.

Sunset smirks and starts playing the guitar like an awesome rock star on stage and stop.

"How's that?" Sunset asked sarcastically.

Flash is shock with his jaws drop and his eyes widen of seeing Sunset playing the guitar so well.

"Awesome!" Flash squealed.
