So, after Frieza was killed, his army withdrew, and Cell went into hiding! Everyone returned to their normal lives. And well Jaco said he would keep in touch. He ended up leaving, while getting scared by Bulma again (as usual). You returned to Canterlot City to live your normal teenage life in your new house!! Although Sunset, realized that she was low on her rent for her apartment, and you decided to let her live with you, much to her delight!! You then offered Twilight, Adagio, Aria, and Sonata to become your roommates too, since they weren't from earth and had no homes. They of course agreed to it.
As you guys are getting settled in your house, which is a nice two story house, containing a king sized bed in the bedroom, and well a bunch of food in the fridge (perfect for a Saiyan such as yourself), you get a call on your cell phone.
(Y/N): Hello?!
Pinkie: Hey there (Y/N)!! I wanted to ask you something.
(Y/N): What is it my little Cupcake?!
Pinkie: I was wondering if Dashie, Applejack, Rarity, Fluttershy, and I could sleepover with you, Twilight, Sunset, Adagio, Aria, and Sonata?!
(Y/N): Sure Pinkie, what's the occasion?!
Pinkie: No reason, just because well, you're new in Canterlot, and well we all want to spend more time with you!!
(Y/N): Sounds good to me!! I'll tell the others right now.
Pinkie: Okay, see you bye!! I love you!!
(Y/N): Love you too Cupcake!
You hang up and then go to talk to Twilight, Sunset, Adagio, Aria, and Sonata about the news. They are on the couch watching some TV. And well, Sonata is scarfing down some tacos as snacks.
(Y/N): Hey girls!
Girls: Hello (Y/N)!
(Y/N): So, I got a call from Pinkie just now.
Sunset: Really, what did she say?!
(Y/N): She is bringing Rainbow, Applejack, Rarity, Fluttershy, and herself over for a sleepover. And I agreed to it.
Twilight: EEE!! Yes a sleepover!! I haven't had one in a long while!! This is going to be so fun!!
Adagio: Hmph, well it looks the princess has the dorky side to her.
Twilight blushes.
Twilight: Yeah I kind of do.
Sonata: You know Twilight, for a Princess, you act more like a high schooler now.
Twilight: I get used to it.
Adagio: Right.
Sunset: So, should I order some pizza for us?!
(Y/N): Yeah, Pinkie and the girls are probably going to bring some of their own food for us too, so I guess that's okay.
Sunset: Alright then, I'm on it!!
Sunset takes out her cell phone and begins to order three large pies, one that is a meat lovers, one that is Hawaiian, and another that is "Supreme!"
Sunset: Hey do you guys want any sides?!
Sonata: Garlic Knots, with a side of marinara sauce!
Aria: Good to see that you like something as much as tacos.
Sonata: I love food in general.
(Y/N): Well that's good to hear! Alright then, I'm going to go and get the food.
You leave the house and begin to fly off to go and get the food.
As you are approaching the pizza joint, you hear a cry for help!
???: HELP!!
(Y/N): Wait that scream sounds too familiar. I better go help this person!
You head to an alleyway, where you see a young blue haired woman being attacked by a gang of thugs!
Thug #1: Just hand over the money and we won't hurt you lady!!
This blue haired lady is Launch, an old friend of yours.
Launch: No!! Stay away from me!! Help!! SOMEONE!!
You attack the thugs with your martial arts skills, and after a couple of minutes, they are on the ground, completely unconscious!
With the bad guys knocked out, you go to check up on Launch.
(Y/N): Hey there Launch long time no see!
Launch: (Y/N)?! (Y/N) (L/N) IS THAT REALLY YOU?!
(Y/N): The one and only!! How have you been!?!
Launch runs up and hugs you tightly in her arms!!
Launch: I've been great!! How about you?!
(Y/N): Just fantastic! I was going to grab some pizza, because I'm having a sleepover with my girlfriends!!
Launch: Girlfriends?! You have more than one?!
(Y/N): Yeah, it's more of a harem. And the girls say that they're willing to let anyone in as long as they admit their feelings!
Launch: Okay then!! That sounds lovely!! I should admit them to him soon! Well, I've been traveling as of late, and I ended up here!! So, do you think I can stay with you?!
(Y/N): Anything for an old friend Launch.
Launch: Thank you (Y/N)!!
You grab Launch and you take her flying to get the food. After you grab the food, you both arrive back home.
(Y/N): Is should introduce you to the girls Launch! You're going to love them!
Launch: Okay then!
You bring her inside, and see Twilight, Sunset, the Dazzlings, Rainbow, Rarity, Pinkie, Applejack, and Fluttershy, all in their pajamas, and barefoot. Rarity was painting their nails, and they were also eating some snacks, and watching TV.
(Y/N): Hey girls! I'm back!! And I brought the pizza!!
Girls: (Y/N)
They all run over to hug and begin kissing your face!!
(Y/N): Oh and I brought an old friend over! This is Launch, she used to live at Kame House with Krillin and Master Roshi for a while back then.
Launch soon moves in and kisses you on the lips!!
Launch: I can't hold it back any longer (Y/N)!! I love you so much!!
(Y/N): Which one, you or your other self!
Launch: Both of us do!! And we want to be part of this harem!! We're fine with sharing it!!
Fluttershy: Of course you can join Launch!! You're such a nice woman to help (Y/N) for a long time!!
Pinkie: You really remind me of Fluttershy though.
Rainbow: Yeah, like you two are sisters or something.
Launch: Well, there is my other self though!
Twilight: Other self.
(Y/N): It happens when she sneezes, her hair changes color and her personality too!!
Launch: Yeah, it can get pretty hec-
Some of Launch's hair gets on her nose.
Launch: AAAH AAAAH! AAAH! AAAH! AAAAHCOOO!!
Launch's hair changes to a blonde color and she begins talking like a tough girl!
Aria: What in the?!
Launch: NOW LISTEN HERE GIRLS!! YOU BETTER NOT HURT MY (Y/N)!! OR ELSE YOU'RE GOING TO TALK TO MR MACHINE GUN!!
Launch takes out a machine gun!! And cocks it!
Sunset: Uh ... yes m'am!
Twilight: We understand!!
Adagio: We'll be on our best behaviors!!
Launch smirks.
Launch: Good then. Now I say we eat!!
Launch kicks her shoes and socks off and she immediately begins eating the pizza.
Twilight: Wow, she's overprotective of you (Y/N)!
(Y/N): Yeah, but I love Launch a lot!! She's a very nice girl in both personalities.
Rainbow: Well I like her a lot!! As long as she doesn't try to blast me with that gun of hers.
Pinkie: Hey let's just go eat!!
Applejack: Yeah I'm starving!!
Rarity: Let's keep it clean though!!
All of you proceed to eat the pizza, and well enjoy the night with your new girl Launch!! It seems that things are going to get livelier with her around!!
Pinkie: See you next chapter folks!! I'm happy to have Launch as my new friend!!!
