Thank you for even thinking about reading my story. I'll try to update regularly, but no promises yet. Anyway enjoy this story, I was with my sister and brother when I had this idea.

Marco and Star were coming home from school like every other day. Star skipped around still fascinated by all the Earth things surrounding her. Marco watched with amusement, she looked like a toddler exploring the world.

"Oh Marco isn't it wonderful, the week is almost halfway over! It's almost the weekend!" she cheered. She was wearing her newest outfit, a sleeveless sky blue dress with striped blue stockings, light blue sneakers and matching legwarmers. With the wand securely in her hand she felt protected. Not like she wasn't worried though, Marco was there to help her defeat Ludo's army.

"Uhuh, if you want to think about it that way Star," Marco said walking behind the princess. In his mind, he was thinking how he would get Jackie Lynn Thomas to notice him.

With the two in their own little world, they didn't notice the change in the air. Right in front of them opened a dimension portal.

Marco was the first to noticed and stopped Star before she walked into the portal. Together they got into their defensive positions, Star holding her wand out ready to give a narwhal blast, while Marco had his karate position ready to strike.

But it wasn't Ludo and his army that popped out of the portal. There was a girlish scream and someone rolled through the portal. The portal closed as soon as the person passed through.

Marco observed the person, not knowing what to do. It was a girl who had passed through, she landed on her hands and knees and started to stand. He still stood in his defensive position, he didn't know who she was.

She had light brown hair that was spiky and was held back by a yellow headband. She had the same blue eyes as Star and, in a way, looked liked her too. Where Star and hearts on her cheeks, this girl had crescent moons on hers. She was wearing a light yellow tank top and a pair of overalls, her sneakers were a darker shade of yellow. Around her neck was a blue moon necklace.

Marco couldn't decide if she was a human person that Ludo was using as a spy (which was actually a good idea) or a friend of Star's like Pony Head.

But Star knew who that was. She jumped up and down excitedly before yelling the girl's name.

"Luna!"

"Star!"

"What?" Marco wondered, looking at the two girls hugging.

Star broke the hug and grabbed her hand. "Marco this is Luna Galaxy, my cousin."

Marco dropped his jaw. "So is she a..."

Marco didn't know how to react. If she was another magic girl like Star, he didn't think anything would survive.

Luna gave a smile. "Yes, I am a magic girl, but I'm not as reckless as my cousin. I would say I am more trained, than she is."

Marco was still confused. How old is she? Why was is she here? Does she have a wand? Or...

"Please tell me you've gone through mewberty!" Marco yelled.

The two girls looked at him with surprise and Marco felt himself blush at his outburst. He did not just ask that question.

Luna laughed. "I'll explain everything to you privately. I don't want anyone to here, Ludo might have people watching us."

Not long later the trio was seated in Star's room to here Luna's story. But they had to wait a moment since Luna was distracted by Star's laser puppies. he played with them for a while.

"Yeah, she's easily distracted," Star said to Marco. She snapped her fingers to grab her cousin's attention. "Luna!"

Luna looked up at the two and dropped the puppy that was in her arms.

"Yes?"

"Not that I don't love you, but why are you here?" Star asked.

Luna sat up completely serious. "When you left for Earth, Mewni was peaceful."

"Hey!"

"Shush, anyway, it was peaceful, but something did happen. While Ludo's after you, he sent a few to stay back in Mewni when he was away fighting you. They wanted to get me unguarded so they could grab the amulet."

Marco observed the necklace he saw earlier. It was a blue crescent shaped moon necklace with a yellow glow surrounding that. Luna rubbed it nervously as she continued to tell the story.

"I was alone in in my room, reading when they tried to attack. It was at night so I wasn't wearing the amulet. It was on my nightstand. They jumped through the window and snatched it, leaving me defenseless. Thank goodness Father came in or I would have lost the amulet. I was sent to Earth to stay with you Star, since you know how to fight and all."

Star ran and hugged her cousin. "You're always welcomed here Luna!"

Luna smiled. "Thanks Star. Marco anymore questions? I did go through mewberty, see?"

She turned around and lifted her hair up to show blue wings identical to Star's own. Star squealed excitedly and showed hers.

"Um Luna?" Marco started.

The said girl turned and faced him. "Yes?"

"How did you get your pendant?"

Luna held her amulet. "Oh I got mine two weeks before Star. I am older than she is. It's a family heirloom on my side. Star gets the wand since she is the princess and since I'm a noble related to the princess, I get the amulet."

"So is it like Star's wand or...?"

"Kinda. Except I have an element. Moon to be exact."

Star grabbed Luna's arm suddenly and violently started to shake her. "Where are you staying?"

"Haven't you heard?" she asked the two. "I'm the newest transfer student!"

Both boy and girl dropped their jaws.

"You're staying here with me?" Star said jumping up and down.

Luna joined her bouncing. "Yes! Isn't it exciting! You can show me everything about your Earth school."

"Alright I can't wait," Star said leading Luna out of the bedroom. "But they have these things called test."

Marco wasn't that thrilled to have two magic girls, but he noticed the difference between the two cousins. While Star was irresponsible and reckless, Luna was more mature and sensible. They were both energetic and sweet, but Luna was very clumsy. She would trip over thin air or anything really. Both weren't very graceful though, but Luna showed more of a noble background than Star.

"Come on Marco school's starting!" Star called out.

Marco grabbed his bookbag and walked out the front door. There waiting were the cousins. Today Star was wearing her turquoise dress with the four colorful stripes on the chest, light blue and green stockings, and pink boots. Luna was wearing an outfit close to Star's party dress except the skirt was blue and the shirt was yellow. She had no stockings on and her boots were blue.

"Good morning Marco," Luna greeted.

Marco waved at the newest addition to the house and the three walked to school together. It wasn't a quiet walk because Luna was asking questions every ten seconds. Marco felt like Star had first come to Earth all over again.

"So will Ludo attack us at school?" Luna asked when they reached the school.

"He hasn't yet," Marco said.

"Maybe he hasn't thought of the idea yet," Star said. "Now, this is our school. Let me show you around!"

Star and Luna abandoned Marco when they ran off. Marco felt a little left out. It was usually him and Star running around the school. Now it was her and Luna. Maybe this is what Star felt like when Gustav came to visit.

"Woah look at the new girl!"

"Who is she?"

"She looks like Star!"

Marco sighed and put some of his books in his locker. Five minutes into the school day and Luna was already being talked about. Marco gave another sigh and closed his locker to be met face-to-face with Luna.

He screamed and fell back, landing hard on the ground.

"Oh my gosh are you okay?" Luna asked helping Marco up. "I didn't mean to scare you."

"Where's Star?" Marco asked as he stood up.

"Oh she ran off. She tried to talk to someone named Brittany Wong, or something like that? I decided to come back over here with you."

"Yeah, that happens," Marco said rubbing his neck. He really hasn't had a face-to-face talk with Luna before. Star had always been with them. Now what was he supposed to talk about. He felt way more comfortable with Star instead of her.

"And I thought I was the easily-distracted," she said giggling nervously.

There was an awkward silence between them before the bell rang signaling for the students to go to class.

"Can you lead me to my first period?" Luna asked. "If it's not too much trouble."

"Oh no! Certainly, I will."

Luna gave a sigh of relief. "Thank you!"

Marco led the way to first period with Luna following behind him. Sometimes he had to grab her arm when she became distracted by something, but other than that she was a sweet person. She wasn't that bad, Marco realized when he sat next to her in first. She just needed little help getting adjusted to Earth.

Thank you so much for reading this it means a lot to me as this is my first story. I do hope to write more. Bye for now!
