Marco comes to Earth.

The kingdom of Mewni, a beautiful place full of life, magic and corn. We, the mewman race, had been living in peace for generations. But there is always something that had been a problem in our kingdom, the monsters. The monsters are an evil race that had been tormenting our people for years. The only things that they always do are stealing and fighting. My name is Marco Ubaldo Diaz, and it is my duty as future king of Mewni to put this to an end. Starting my own story today, my fourteen years anniversary, that my parents will hand to me the magical royal wand. The wand that had been passed by generations through my family. The ceremony is ready and all the nobles are waiting for my parents to finish their speech. Everything will change, today.

Marco closed his journal and stood up from his desk. He exited his room and made his way to the throne room, where his parents were waiting for him to give him his birthday present.

"And with all that said, we are very glad to pass the royal wand to our son! Prince Marco Diaz!" Marco's parents said excitedly in unison. Marco entered the room wearing his royal clothes and his prince crown as soon as his parents told his name.

Marco walked through the hallway until he reached his patents.

"Here it is son." His mother said while giving the wand to Marco. Marco grabbed it and the magic of the wand started to play. The wand started to shine in a white light while it changed its form.

The wand changed from being a floating blue crystal ball with a golden handle with white stars on it to being a wand in form of a dagger. The color black handle with the now golden crystal in form of the dagger's blade. The crystal wasn't sharp at all, it just had the form of the dagger's blade.

Marco's eyes went wide when he saw the wand's new form. "Thanks mom." Marco said smiling at his mother.

"Oh Marco, it's nothing." Marco's mom said while pinching one of his cheeks and watching at her son's cheek marks. Marco's cheek marks were bright red diamonds while her mother had pink hearts.

"Mom, you're embarrassing me in front of the nobles." Marco whispered to her mother.

"Oh, yes, sorry." Her mother let go his cheek. Marco turned around and raised his new wand into the air.

The nobles applauded and just like that, the ceremony was over and the throne room was empty.

"Now tell me son, what are you planning to do first with your new wand?" His father asked excitedly.

"I don't know, maybe I could start with a magical shield to protect our kingdom!" Marco made his way out of the throne room and went outside the castle.

His parents just followed him to watch his actions from close.

"Protectirus Monstrusios Shieldious!" Marco cast the spell while pointing the tip of his dagger upwards. A light blue flash came out of the dagger's blade.

The light went upwards and fall into the corns field protection shield, breaking it.

His fathers and he gasped.

"Um… don't worry I can fix-" Marco was interrupted by the shouts of monsters that were racing towards the fields of corn."Hey! That's our corn!" Marco shouted while pointing his dagger to the monsters horde.

The wand blasted a green energy that landed in front of the monsters. The green energy started a little fire.

The monsters laugh at the insignificant flame, but the flame quickly got larger and larger until the monsters actually decided to run away.

"See? Told you I could do it!" Marco face his parents with pride.

"Marco, the corn! Protect the corn!" His dad shouted. Marco turned around and saw the flames near the corn.

"Don't worry, I got this!" Marco said while casting the same spell of the force shield towards the corn fields.

The dagger blasted the same light blue flash. The blue flash was going directly to the corn fields. But it went right upwards when it was about to reach the corn. The corn was reached and quickly consumed by the flames.

All of them gasped in horror.

Marco's mother put a forced smile on her face. "Well, look at the bright side, at least it can't get worse than this."

The blast of Marco exploded in the air, creating a fire rain. Everybody in the kingdom took cover until the rain stopped. The flames were starting to consume the kingdom, but luckily, the royal guards put all the flames away just in time.

Meanwhile, inside the castle. Marco's parents were talking about their son's magical abilities. With the help of Glossaryck, they chose the right thing to do. The rulers of Mewni ordered the guards to pack up the things of the prince.

Marco was in his room when the guards entered and started to take all his things out of his room inside some boxes. "What is happening here?! Stop!" Marco shouted and his parents went inside his room.

"Relax Marco, we ordered them to pack up your things." His father said to him.

"What? Why?" Marco asked.

"Well, you see… We had been talking about this for some time and decided to send you to-"

"ST. HEINOUS SCHOOL FOR USELESS PRINCES?! NO, PLEASE DON'T!" Marco shouted scared.

"What? No, no, we are not going to send you there." Her mother said softly.

Marco let out a sigh of relieve. "Well, in that case. Where are you sending me?"

"We are going to send you to a safer place for you to practice with the wand properly. The place is called Earth."

From outside the castle, a really big frog monster was watching the scene through the window.

They were already in the principal Skeeves office negotiating the inscription of Marco into the school. Marco was wearing some earth clothes his parents thought he would like. A gray shirt, jeans, a pair of shoes and a red hoodie.

"So… you came from another dimension? And you are the rulers from an entire kingdom? And you want our school to take your son, the prince, into our educational program?"

"Yes, could we start to talk about when he can be introduced properly into the institution?" Marco's mom asked when the lights of the office went off. Everyone in the office turned to Marco that was standing right next to the switch.

"What kind of dark magic is this?" Marco asked.

"I think this is not going to work." The principal said.

"Oh really? Well, in that case, I guess we could search another school to give this handsome reward for our son's education." The queen said while opening a wood box full of gold and jewels.

"This will definitely work!" Principal Skeeves said full of joy.

"Really?" Marco asked.

"Of course! But you should first clean off that make up from your face."

"Make up? What make up?" Marco asked confused.

"Those red things you have in your cheeks." Principal Skeeves said while hugging the wood box.

"You mean my cheek marks? What's wrong with them?" Marco asked.

"Well, the guys around here usually don't have those things on their faces. So if they see you with those in you cheeks, they might be bullying you for that."

"But-"

Marco was interrupted by his mother. "No Marco, it's alright as long as they don't treat you like that." The queen said as she got some make up for his cheek marks and cover them with it. "There we are." The queen said while looking at her son. "Take this too, you will need it." The queen said as she gave him the makeup. "I'll make sure to send you more when you need them."

Marco looked at his mom. "Thank you, mom."

The queen and king had to leave. Before leaving, they gave their son a familiar hug and left.

"Well, now that we are ready. I think I will need the help of a guide." Marco said to Principal Skeeves.

Another boring day, in another boring class of the boring Miss Skullnick. Everyone was quiet in the classroom taking notes about the class, everyone except for one girl that was in the last line drawing random things to keep herself entertain.

A voice was heard through the speakers.

"Star Butterfly, please meet Principal Skeeves in the hallway near the entrance."

"Huh? What did I do now?" Star asked herself.

"Well, you hear it. Go and find Principal Skeeves now!" Miss Skulnick excused her.

Star quickly made her way out of the classroom. She didn't care about being in problems or not, she was just relieved that she wasn't going to be for some time inside that boring class.

Star jumped happily to the hallway. "You were looking for me, Principal Skeeves?" Star asked with a smile on her face.

"Yes, I need you to do something for me." Principal Skeeves said.

"Sure, what is it?"

"Well, you see the guy over there?" Skeeves said while pointing at Marco that was inspecting the lockers.

Star nodded.

"Well, he's new and I need you to be his guide."

Star gasped with excitement. "Really?!"

"Really, he's an exchange student and he will need a guide through the school and the town, and what better student to do it than the one that is going to foster him."

"He's going to stay with me?!"

Principal Skeeves nodded. "Your parents already know this, so there's nothing to worry about. Now if you excuse me. I am going to the ice cream post!" Principal Skeeves said while leaving with the wood box in his hands.

Star approached at the new guy quickly and shook his hand. "Hi, I'm Star! I'm gonna be your guide and we are gonna have so much fun!" Star said while still shaking his hand.

"Greetings, it is nice to meet you Star… Um… Excuse me, what was your second name?"

"Butterfly, Star Butterfly! At your service my new friendly roommate!"

"Roommate?"

"Yeah, you are gonna be staying with me and my parents! It will be like having a sleepover every night and hanging out every day!"

Marco was processing all the information that this girl was giving him. After that, he broke the silence. "Then, you are my guide, right?"

"Of course!"

"In that case, could I ask you two things?"

"Sure!"

"Good, first of all. I want you to show me the facility and how things work around here."

"Yeah, that will be easy! What's the second thing?"

"I want my hand back." He said calmly.

Star looked at her hand that was still holding his. "Oh, right!" Star released Marco's hand.

"Thanks, could we start the tour now?" Marco asked gently.

"Alrighty, follow me!"

Star was walking around the school while showing and explaining everything to Marco. Sometime later, the tour was over and it was time to go home. They both walked together towards Star's house while talking in the way. Star was asking so many things about him, Marco told him that he was from a place called Mewni and he was sent here to learn in a better and safer way. He avoid mentioning that he was a magical prince from another dimension and the fact that he had a magical wand inside his new backpack.

They kept walking and talking until they arrived to the Butterfly's house.

Star opened quickly the door and shouted. "Mom! Dad! We are home!"

Star's parents went out of the kitchen and greeted her daughter.

"Welcome back Star, how was your day at school?" Star's dad asked to her cheerful daughter.

"It was great! The cafeteria was giving my favorite food! I made a cute little drawing of a cloud with rainbow arms in the art class! And I made a new friend!" Star said excitedly. Star grabbed Marco and pushed him in front of his parents. "Mom, dad, this is… Um… Sorry but… What's your name?"

Marco rolled his eyes. All that time walking and talking. And she didn't even asked for his name until now.

"Oh, you must be the exchange student. Marco Diaz, right?" Star's mother said to the boy in front of her.

"Yes, that's me." Marco shook slightly Star's mother hand. "It's nice to meet you, Mrs. Butterfly."

"Nice to meet you too, Prince Marco." Star's mother told to him.

Marco looked nervous. "W-What? P-Prince? Who told you that?"

"Don't worry boy, your parents were here earlier and told us everything." Mr. Butterfly told him.

Marco let out a sigh of relieve. "Well, that's good to know."

"WHAT?! YOU ARE A PRINCE?!" Star asked with surprised.

"Yes, I am."

"Why you didn't told me?!"

"Because my parents and the principal told me to kept it as a secret. So now that you know, I'm going to ask you to not tell anybody."

"Not only that. He's also from another dimension and has magic!" Mr. Butterfly told to her daughter.

"Really?!" Star's eyes widened. "Show me, show me, show me!" Star shouted excitedly.

"I would like to see your magic too. I am not still fully convinced about that part." Mrs. Butterfly asked softly.

"Alright, let me just get my wand and I'll show you." Marco said as he was getting his wand from the backpack. Marco grabbed the wand out of his backpack and show it to them. He didn't expected to be tackled by Mr. Butterfly, making him to drop the wand. "HEY! WHAT ARE YOU DOING?!" Marco yelled.

"No one threatens my family!" Said Mr. Butterfly while he was pushing Marco against the wall.

"NO! YOU DON'T UNDERSTAND! THE WAND IS SUPPOSED TO LOOK LIKE THAT!"

"Sure, and I was born yesterday!"

Star approached at the wand that was lying in the floor. "You sure? This doesn't look too magical or too wand-ical to me." Star said.

"No, wait! Don't pick it up!" Marco yelled at Star.

Star picked it up anyway.

The wand started to shine in a white light and proceed to change its form. The dagger looking wand change into a color pink and purple wand, a pair of little wings appeared in both sides of the wand, the crystal changed its blade form and turned into a golden star that was incrusted in the center of the new wand.

Everyone looked amazed at the wand that Star had in her hands.

"Wow! Now it looks more like a wand!" Star said cheerfully.

"It looks more like a rattle to me." Marco said a little annoyed.

Star shook happily the wand. Some chimes could be hear from inside.

"Never mind."

"Ops, looks like it is a magical wand after all. Sorry." Mr. Butterfly said as he release Marco.

Marco hurried his way towards Star. "Give me back my wand!"

"But it looks so cute this way! Maybe I should keep it safe for you."

Marco gave a glare to Star.

"Star, please give the wand back to Prince Marco."

"Okay mom." Star turned to Marco and handed him the wand.

Marco grabbed the wand and it returned to its dagger form.

"Oh dear, I am so sorry for what happened. My husband can be a little aggressive sometimes." Mrs. Butterfly apologized.

"No, it's alright. It was my fault for not explaining the situation beforehand." Marco apologized too.

"I'm so sorry for what I did, Prince Marco." Mr. Butterfly said.

"Do not worry Mr. Butterfly. I already forgave you." Marco replied.

"Well, now that we are all friends and we have no more secrets. Why don't you tell us about your dimension?" Star asked happily.

Marco and the Butterfly family sat on the living room. Marco told them almost everything he knew about Mewni, and they told him the important things he had to know about earth.

"This is a great opportunity for you and us to experience new things, and speaking of new things. Star, could you show Marco his room, please?" Mrs. Butterfly asked to her daughter.

"Of course!" Star ran upstairs and shouted. "Follow me!"

Marco followed the cheerful blonde girl all the way to his room. "It's a little more… reduced than I expected."

"Well, you could make it bigger if you "wand" it!" Star said giggling.

"No, that's okay with… wait a minute, was that a…"

"Yes, yes it was." Star interrupted him.

They both look at each other in silence.

Marco tried his best to not laugh. "Well, as I was saying, I'm fine with this. Besides, I'm not that good with magic. That's the reason why they sent me here." Marco stated while looking at Star that had a big smile on her face. "Um… Why are you smiling like that?"

"I made it!"

"You made what exactly?"

"You chuckled. I made you laugh!"

"What?! No I didn't!" Marco said while increasing slightly his voice.

"Yes you do!"

"No I don't! As future King of Mewni, I have to stay serious and calmed all the time!" Marco said while rising his right hand and arm to his chest height.

"Come on! You need to have fun! Everyone needs to have fun!"

"I don't, the only thing that I need is training!"

"Aww, don't be like that. Let me see your smile!" Star said as she grabbed Marco's cheeks and pulled them up. "Look at that big smile on your face!"

Marco grabbed her hands and pulled them away from his face. "Stop it!" Marco looked at the now confused Star. "Hey, are you alright?"

Star let go a giggle that was cover by her hand.

"Hey, what's so funny?" Marco asked the girl in front of him.

Star was pointing at his face.

"Do I have something on my face?" Marco said confused.

"Your cheeks." Star said while quickly covering her mouth, holding back the laugh.

"What do I…" Marco realized why she was laughing. He grabbed Star's hands and saw all the make up all over them. Marco turned around to face the mirror behind him.

"Looks like I am magical too." Star said through her laughs.

"No, you only cleaned the make up from my cheek marks. Which is, a big relieve."

"Wait… Cheek marks? So those are natural?" Star asked confused.

"Yeah, every heir has their own cheek marks. My mother has pink hearts and I have these red diamonds."

"That's so cool! I wish I had my own cheek marks!" Star exclaimed.

Marco explained to her everything that she asked about the magic topic. The cheek marks, the mythical creatures that existed in Mewni but in earth were only fairy tales and the monsters, until Marco change the topic.

"Um… Excuse me, can I ask you a favor?"

"Sure! What is it?"

"Could you show me the town? I don't want to be wandering around if I ever get… Lost."

"Sure, I am your guide after all!" Star hoped off the bed and grabbed Marco by the arm. "Just follow me!" Star said as she ran downstairs while pulling Marco by his arm. "Mom! Dad! We're going to see the town real fast! Be back before dinner! Bye!" Star said as she got out of the house still grabbing Marco.

"Have fun, sweetheart!" Mr. Butterfly waved at his daughter.

"Be careful out there, you two." Mrs. Butterfly told them.

Star was guiding Marco through the town while she showed him all her favorite places. They were walking around the town until it was starting to fall the night.

"Um… Star, I think we should go back now."

"What? But this was your idea!"

"Yes, but you promised your parents to be back before dinner and it's starting to get dark already." Marco said nervously.

"What's the matter? Are you afraid of dark?" Star said mocking.

"No I'm not! I just don't want to upset your parents. I'm supposed to be the responsible one if something bad happens."

"Huh, why?" Star asked to her friend.

"Because I'm the prince, the future King of Mewni. I have to take responsibility for my actions."

"Come on, just chill. I mean, what's the worst that could happen?"

Suddenly, a horde of monsters jumped out of the bushes and the trees, surrounding them.

"What?!" Star exclaimed surprised. She didn't expected that to happen all of a sudden.

"What is happening here?!" Marco asked to the monsters.

A little tiny monster riding in a little bat monster called their attention. "Surprise Prince Marco!" The little monster shouted at them.

There was a moment of silence.

"…Do I know you?" Marco asked.

"What? You don't know who I am?"

"Not at all."

"Really? I'm Ludo! The most dangerous and clever monster of them all!" Ludo shouted towards the sky.

"Sorry, not ringing any bells."

"You are the most dangerous monster? But you look so tiny!" Star told to Ludo.

"I only look like this because I don't have my big boy body yet!" Ludo yelled at her.

"Aww, do you hear him? He doesn't have his "big boy body" yet!"

"Silence!"

"Don't worry little one! I'm sure you will grow up enough to have your "big boy body" someday!" Star said smiling at him.

Ludo's monsters were trying their best to hold back laughter.

"Enough of this! Now, GET THE WAND!" Ludo shouted in anger.

Marco pulled off his wand out of his hoodie pocket and aimed the tip of it at them. "Royal blast!" A light blue blast came out of the wand and strike all the monsters in its way. Marco turned around to watch other monsters approaching at him. He prepared his wand for another Royal Blast, but Star got in front of him.

"A fight?! Don't leave me out!" Star shouted happily as she jumped into action. Star punched the monster in front of her in the stomach. She kicked the same monster to slam it against the others in the back. One monster approached her from behind and before it could punch her, Star turned around and delivered an uppercut.

Marco looked at her astonished. "Where do you learnt how to fight?"

"The T.V!" Star shouted as she continue with the fight.

Marco and Star were handling very well in the fight. Marco was blasting every monster with his wand while Star was delivering punches and kicks to every single monster that dare to approach her.

Ludo couldn't believe that all of his monsters were being beating up by an unexperienced prince and a hyperactive teenager. Before he could even shout how incompetent they were, the fight was over.

All of his monsters were lying on the ground and groaning in pain.

Ludo let out a sigh of defeat.

"What's the matter? Not so dangerous now?" Marco asked mocking at the little monster.

Ludo walked away while making a tantrum. He withdrew his dimensional scissors and opened a portal. "Alright everyone! In the portal! NOW!" Ludo shouted to his monsters.

The monsters were getting slowly on their feet while still groaning in pain. Every monster cross through the portal.

Ludo enter the portal. "This will not be the last you hear from me Prince Mar-KKHG!" The portal closed while Ludo had his head outside it. Ludo quickly pulled his head inside the portal, dropping his skull hat.

Star rushed to pick up the skull. "This is going to my room!" She said as she put it on.

"Now you see what the worst that could happen was?" Marco said to Star.

"What are you talking about? That was really fun!"

"It was dangerous!"

"But mostly fun!"

There was a moment of awkward silence between the two of them. They were just staring at each other until Star let out a sigh and talked.

"You're right, that was pretty dangerous."

Marco's expression changed from mad to surprise.

"I mean, they were too many and only two of us. What if we couldn't beat them? They would have taken your wand. And it would have been my fault for not listening to you. I'm sorry."

Marco looked at Star. He couldn't believe that she was really apologizing to him and taking responsibility for what happened. "Hey, it was not your fault. Those monsters only came for my wand, I think they would have attacked us anyway." Marco said while putting a hand on her shoulder.

"Really?"

"Yeah, I think so."

There was another moment of silence before Marco spoke.

"And I have to admit. It was actually pretty fun." Marco said with a tiny smile on his face.

"See?! That's what I'm saying!" Star quickly said with a big grin.

"And the way you fought those monsters was really great! Maybe you could teach me how to fight like that?" He said as they started to make their way back to Star's house.

"Sure! I can show you the T.V. programs from where I learnt that!"

"Who's this Tebee you are talking about? Is it your teacher?"

"I promise to explain it to you as soon as we arrive home."

"Alright! I can barely wait!"

Star looked at Marco that was looking at the night sky. She smiled and said to herself.

"I made it!"
