A/N: Here's the first official chapter! Enjoy!
Chapter 1: Star Comes to Earth
Star Butterfly had just turned 14, the age of then the Princess of Mewni inherits the family treasure, the magic wand.
Star was different than other Princesses however, she fought monsters, often with the help of her brother Luffy.
Well her brother was a sworn brother, she and two other boys joined in a ritual to become brothers and sister when she was 7. The other two stopped joining on the monster fights because they both went off to become pirates.
But that didn't mean they didn't visit. They just visited occasionally after they became pirates, with both of them being captains of their own pirate crews.
In fact both of them were there to visit during that day, as it was a big day.
Most of the crowd was nervous.
"So…" said Luffy who was the same age as Star, had spike black hair and wore a straw-hat hat, "How do you she's going to enter?"
"Probably break down the doors someway." Said the oldest of the three, ace who had black hair like Luffy, expect his was long and he has freckles and his hat was an orange cowboy hat.
"Came on that's too simple for star." Laughed their middle brother Sabo, who was blonde and his trademark hat was a top hat with a set of goggles on it.
"What you seriously think she'll drag in a monster." Said Ace.
"I wouldn't go that far." Said Sabo.
"I say she's going to ride in on a wild unicorn." Laughed Luffy.
Neither Ace or Sabo said anything they just looked at each other and nodded.
They learned a long time ago never bet against him.
And indeed Star rode in on a wild unicorn that crashed though the wall as it left.
"Now Star." Said Queen Moon, Star's mother, "You have to be careful, if the wand ever falls into the hands of evil the universe could be destroyed."
Queen moon handed Star the wand which transformed into a different shape when it happen, going from a wand with a blue crystal to a pink wand with the a yellow crystal star in it with little wings on the side.
"Don't worry, mom I can totally handle it." Said Star.
Sometime later she set the kingdom on fire with a burning rainbow.
And so Star was getting ready to leave, with Luffy comforting her.
"Please don't send me to Saint Olga's School for Wayward Princesses!" cried Star.
"Please don't Queen Mom!" said Luffy.
Queen Moon just sighed, she was used to Luffy calling her "Queen Mom" and she gave up correcting him long ago.
She turned her attention to Star.
"We're not sending you there." Said Queen Moon.
Star immediately perked up.
"Oh!" she said.
"We're sending you to Earth." Said Queen Moon.
"Earth! Why can't I be sent to the Blue Dimension." Said Star.
"That place is dangerous, considering all of the pirating going on." Said Queen Moon, "It's no place for you."
That Blue Dimension of the name of Luffy's home dimension, however Queen Moon didn't know that fact.
"You won't be allowed to leave, Luffy you may visit her but you can take her anywhere." Said Queen Moon.
"All right!" said Luffy.
Star looked at Luffy, she knew he wouldn't listen to that one rule.
Especially since the dimensional scissors he had were his own pair that he had gotten years ago.
And so Star was taken to Earth to be a foreign exchange student.
While there she met a fellow classmate on Earth named Marco who showed her around school then got weirded out by her Magic, and then found out she was going to be living with him and his family.
Things weren't going well for the two of them, such as Star creating a litter of puppies that shot lasers out of their eyes and then Star just destroyed his room with a black hole after trying to make it better.
"'Suck! "Suck!" Why was the word suck in that spell!" yelled Marco.
"I don't know" cried Star, "It just came out that way!"
Before Marco could say anything else suddenly something cut the air and a bright blue portal appeared, causing Marco to jump.
And out came Luffy, Ace and Sabo.
"Hey bet you weren't expecting us so soon." Said Ace.
"Hugs!" cheered Star hugging her brothers.
"What…" said Marco confused.
"So how are things so far?" asked Sabo.
"Oh you know! I made a new friend." Said Star motioning to Marco, "Oh Marco these are Ace, Sabo and Luffy! Ace and Sabo are pirates and Luffy going to be omen one when he turns 17."
"Pirates…' said Marco with his eye twining, "Of course you're friends with pirates!"
"Their not friends." Said Star, "They're my sworn brothers! That's completely different!"
"Okay! Okay! This is getting weird!" said Marco.
"Come on you just need a little Sunshine!" said Star.
She pointed her wand at him and created a rain cloud on accident.
"That's it!" yelled Marco, "Both of them cant' live here, if you're here. So I'm leaving!"
He ended up jumping out the winnow, Star, Ace and Sabo all cringed as he did. Luffy however got distracted by the laser puppies.
"You okay!" called out Star.
"Luckily the cacti broke my fall!" said Marco.
Marco got up and limped away.
"How long have you been here again?" asked Sabo.
"A few hours." Sighed Star.
Sometime later they found him outside a convince store still with the raincloud raining on him trying to get a refill for his soda.
He jumped in shocked when he saw Star and her brothers.
She zapped the cloud away.
"I didn't get a choice in coming to earth and you didn't have a choice in having to deal with me." Said Star.
Marco's face softened a little.
"I'm going to be staying with Luffy for a while." Said Star, "Hopefully mom won't find out and send me to Saint's O's."
"And if that happens you know Luffy will just break you out." Said Sabo.
Star laughed a little.
They began to leave, however Marco saw something behind them.
"Star…" he said nervously.
They turned and saw a group of monsters.
"Star Butterfly! At least I found you." Said a small kappa wearing a bull's skull.
"Ludo! How did you find me?" asked Star.
"Wouldn't you like to know!" said Ludo.
"Yes… that's why I asked!" said Star.
"Well Buff-Frog here…" said Ludo, "I don't have to tell you! Get her!"
Star, Luffy, Sabo and Ace all got into battle positions.
However what surprised them was when Marco punched one of the monsters hard.
"You can fight!" said Star surprised.
"Awesome!" said Luffy.
"It's called karate!" said Marco proud f his abilities.
That was when Sabo grabbed a pipe from his back and began to beat up many of the monsters.
"Hey! Marco want to see something cool!" said Luffy.
He turned to the monsters.
"Gum Gum Pistol!"
He shot his arm at one of the monsters and gave a hard punch sending it flying.
"No way!" said Marco, "How?"
"I'm a rubber man!" said Luffy stretching his cheek.
"Wait! You didn't say her brothers are here! Not to mentioned that karate kid!" yelled Ludo, "You said she was unguarded"
The monster known as Buff-Frog didn't say anything.
"Fire Fist!" called out Ace.
His fist turned into fire and he launched the column of fire at the monster.
"Wait! Since when do you have fire powers!" yelled Ludo.
"Wouldn't you like to know." Said Ace.
"Yes, that's why I asked." Said Ludo.
Both Ace and Star laughed as the irony wasn't lost on them.
That was when Buff-Frog tried to attack her.
"Jelly Bean Hallucination Mist!" called out Star.
And of course Buff-Frog began to freak out as he saw faces appeared on his hands.
"Gum Gum Whip!" called out Luffy whipping his leg at many of the monsters.
A giant chicken like monster began to shoot large eggs at them, Sabo managed to bat one of them back at the monsters.
Ace mean launched some fireballs at his enemies.
Marco proceeded to give some of the monsters a flying kick.
"Mega Narwhal Blast!" called out Star.
She sent out a giant Narwhal at them crushing Ludo.
"s you want some o this Ludo?" asked Star.
"No thank you." Said Ludo coming out from under the narwhal.
They watched as they pathetically retreated, with Ludo getting his dead stuck as he made one final threat t.
"That was amazing! You guys were amazing! I was amazing!" cheered Marco.
"I guess we were!" cheered Star.
She then sighed, "I well I better go pack my bags."
"Come on! You can finally do what you always wanted to the tree house." Said Luffy.
"Wait… Star." Said Marco, "I want you to stay with us!"
"Really?" asked Star she gabbed him and cheered "Hugs!"
"So are we going to be fighting monster all the time?" asked Marco excited.
"Probably, just don't expect Ace and Sabo around a lot." Said Star.
"Yeah, we have crew obligations and all." Said Ace.
"We just wanted to check up on our little sister." Said Sabo.
"Take good care of her." Said Ace.
"Hey! But I'll be here!" said Luffy.
"Awesome!" said Marco.
Marco and Star headed home happy with their friendship… and indeed it was the start of a brand new adventure.
