A/N this is set in a sort of au where after Storm the Castle, Ludo regrouped the monsters that had escaped and still hunted Star's wand, and now hunts for the wand from Esme. Also, the wand isn't broken now.

Esme Butterfly-Diaz is the daughter of Queen Star Butterfly and King Marco Diaz. She has lived on Mewni her whole life. After her parents got married, Star had to become queen when Queen Moon had passed away. The happy couple moved to Mewni and have lived there since, with occasional visits to Earth. After accepting her role of queen, Star had really matured and became more responsible, but mostly with the help of Marco. He stayed by her side for everything, even her mental breakdowns towards the beginning of her new life as queen. He would comfort her whenever she needed.

Esme was born. She was beautiful, with dirty blonde hair, usually worn in a half-and-half style. She grew up as ecstatic as her mother, and she looked a lot like her as well. But the biggest thing that made Esme an anomaly was her mismatched eyes. Her right one was brown like her father, and her left own was blue like her mother. She had her father's mole, and a lot of freckles on her cheeks and nose.

Now, Esme was turning fourteen. And as per tradition, Star must give up the royal wand, and give it to the half-human princess. Esme was so excited; she was running all over the castle cheering about her birthday and ceremony.

Soon the ceremony arrived. Esme was dressed in her royal gown, her hair in two plaits down her back. She was bouncing outside of the great doors while her parents introduced her to the people of Mewni. She could her mother's voice from the other side of the door.

"And now, may I present, Esme Butterfly-Diaz, princess of Mewni, and now, beholder of the royal magic wand!" Star's voice boomed across the hall. The two guards outside with Esme opened the doors for her, and she stepped in the hall. The Mewmans around her bowed and curtsied, but she didn't notice. She just looked up at parents who stood up from their thrones. Both were smiling sweetly and Star was wiping her cheeks as tears threatened to spill over.

Esme bounced up to her parents, all the way up the stairs. She turned and waved at the crowd, several of them waving back. Marco coughed and Esme blushed, turning with a sheepish smile on her face. Marco smirked, and laughed a little at his daughter's expression.

"Now, Esme. The wand is special. You know that. You mustn't abuse it like I did, and you mustn't let it fall into the wrong hands." Star said quietly, so just the royal family could hear. "I'm so proud of you sweetie." Star held the wand out to Esme, as the hyper princess grabbed it. It shook and changed. It was simpler version of her mother's. It still had the star in the centre, but had no wings, and was pink and turquoise, like her favourite hair bobble.

Esme gasped and smiled at it. She then looked at her parents and saluted. "I won't let you down."

"Yes, we know, because we have more news." Marco said, pulling Star closer to him. Esme looked at the couple with a confused look. The king and queen laughed at her expression.

"We are setting a new law. Every princess at the age of fourteen, after receiving the royal magic wand will be sent to Earth so they can handle the powers they have been bestowed." Star announced to the crowd.

"What?!" Esme cried, a smile forming on her face.

Esme was flicking a light switch. Star rolled her eyes and laughed a little as her daughter did the same thing her did when she first came to Earth.

"Skeeves, please, give Esme a chance." Marco begged. Skeeves sat at his desk with an unimpressed look on his face.

"And have another Butterfly run rampant around my school? 21 years after you came here? No chance." Skeeves relaxes and leans back on his chair. Star sighed and held out a chest. Marco opened it to reveal the gold and jewels inside.

"Okay!" Skeeves reached forward like a child, trying to grab the chest.

"But before you get this, you have to do the same as what you did for me." Star said, but Skeeves only raised an eyebrow in confusion. "A guide. Esme has never been to Earth before. She'll need help when we can't give it."

"Fine. I'll call in Alex Bridge, just give me the gold!" Skeeves grabbed the chest before they could pull it away again.

Star and Marco turned towards their daughter who was looking at the pictures on the wall of Skeeves' office.

"Esme?" Star called gently. The princess turned around to see her parents with tears in their eyes.

"We love you so much sweetie." Marco kissed her on her forehead.

"We'll miss you. We'll call every day to see how you're getting on. A boy will show you around school and Earth; you'll be living with him as well." Star held out a pair of scissors. "So you can go on a few adventures when you need to." The scissors had a pink grip on one blade, and a turquoise one on the other, like her wand. "And you're going to be living here." Then Star handed her note, with an address on it.

"I'm gonna miss you guys!" Esme ran into their arms, pulling them closer to her in their final hug. "But, I'll be fine."

"We know you will." Marco said. The king and queen kissed her forehead and cheeks. They smiled, and pulled out a pair of their own dimensional scissors. Esme waved at her parents as they went into the portal they had cut into the space around them.

"Alex Bridge to the principal's office. Alex Bridge to the principal's office." Skeeves' voice called over the loudspeakers. A boy, with tanned skin, green eyes and dark brown hair looked up from his work. He sighed, stood up, grabbed his bag, and walked out of the classroom. He sauntered down the corridor and outside, then into a different block. He walked past lockers and classrooms until he found himself outside of Skeeves' office. He knocked, respectful, and heard a voice on the other side letting him come in. He opened the door and saw Skeeves at his desk, and girl in the chair in front of it. He raised an eyebrow before Skeeves spoke up.

"Alex, this is Esme Butterfly-Diaz. Her mother first came to this school 21 years ago. She met Esme's father here." He explained. "She's our new foreign exchange student. Her parents requested a good student to keep an eye on her. And I thought you would be best."

"HI!" Esme cheered, waving at the human boy in front of her. "I'm Esme. But my friends call me E." She held out her hand for him to shake.

"We're not friends, Esme." Alex answered. Esme, disappointed, let her hand fall to her side.

"Yet?" She wondered, hopeful.

"Possibly." Alex shrugged. He turned to Skeeves. "What am I supposed to do with her?"

"Show her around the school. She didn't grow up on Earth, she'll be lost." Skeeves answered.

Alex groaned but turned and walked out the door. Esme grabbed her bag and followed him excitedly. She caught up, and skipped along behind him.

"Thanks for showing me around. This place is so cool!" Esme cheered, her face showing nothing but excitement.

"So, you have to tell me. Where are you from?" Alex wondered, raising an eyebrow at the princess.

"I'm from another dimension! It's called Mewni, and it's really nice there. It was my birthday yesterday, and I got this," She pulled out her wand from her bag. "As a birthday present."

"What is that?" Alex pointed at the wand in her hand.

"The royal magic wand." She stated casually.

"Royal?"

"Yeah, I'm kind of a princess. But the Mewmans don't accept it cause I'm half-human."

"What's wrong with that?"

"Um, a princess who isn't a pure blood Mewman? You know nothing about monarchies."

"Nope. At least, not ones that aren't from Earth." Esme shrugged at his point and continued to skip along behind him. "So, why have you come to Earth?"

"New law my parents set." Esme waved her hand dismissively. "It just means that every princess, after they turn fourteen and receive the wand, have to go to Earth to control it. My mum had it, so she thought it would be best if I did."

Suddenly, the bell for the end of the day rang out. Esme screamed and grabbed onto Alex's arm. The human boy sighed in relief at the alarm. He pushed her hand off his arm before turning to look at her.

"That bell means the end of the day." Alex clapped his hands together. "And, sadly, that means the end of our tour."

"Aww, but I was having fun!" Esme groaned, her face falling at the knowledge of what the bell meant.

"Well, can't help ya there, princess. I gotta go home, and you gotta find where you're staying. So, see ya around." Alex turned on his heel before walking quickly in the opposite direction.

"Okay, bye!" Esme called as he walked away. "I'll see you tomorrow!"

When Alex reached his house, he was very tired. He just wanted to get inside, and flop on his bed. After doing his homework of course. He couldn't get in trouble for it not being done. He fished his keys out of his pocket and inserted them into the lock on the front door.

He instantly regretted opening the door.

There, sitting between his parents on his sofa, was Esme Butterfly-Diaz. His mum was holding her hand, and his dad had his arm around her shoulders. They were under her spell.

"Oh, Alex, sweetie," his mother called and beckoned him over. "Come meet the new foreign exchange student who'll be living with us."

"What?!" Esme cheered in exhilaration. "This is your house?! Awesome! At least you're someone I know!"

"Yeah. Awesome." Alex said, his voice dripping with sarcasm. "But you told me I had a surprise. 'A new friend living with us'. I thought you meant a pet."

"You know what?" Esme grabbed Alex's arm. "I have always wanted a pet." The princess raised her wand, light swirling around it. She pointed it at the ground and a few pugs spawned on the ground. She giggled, and stated how cute they looked.

"Alex, why don't you show E her new room." Mr Bridge suggested. Alex sighed as Esme cheered again. The ecstatic princess bounced up the stairs while Alex trudged up behind her, carrying a relatively heavy trunk.

"Here's your room." Alex said as the pair walked into the room next to his. It was small, with a small bed and a small window. Definitely not fitting for a princess of Mewni.

"I can work with this!" Esme jumped into the air and yelled a spell Alex couldn't quite understand. A bright light shone through the room, coming from Esme's wand. Before he knew it, the room was medieval and modern at the same time. It reminded Alex of Aladdin somehow.

"Woah. This is really cool." Alex breathed, his voice filled with awe as he looked up at the three-story room around him.

"Thanks! My magic's pretty awesome, isn't it?" Esme bounced on the bed she had conjured.

"It would be more awesome if I had a room like this."

"I can do that for you!" Esme grabbed Alex's arm again and dragged him to his room. She swung the door open. "My mum made this spell."

"Esme?" Alex's voice wavered in fear of what the princess could do.

"Mystic room suck transform!" Esme called out, light emitting from her wand again. A black hole formed in the floor of his room. Wind picked up inside the small room, and the furniture started to move. They were soon pulled into the gaping hole on the floor, Alex and Esme screaming as they tried to close the door before they were sucked in as well. Alex slammed the door closed, outside of his room a lot calmer than inside. Well, aside from his bubbling anger.

"Suck?! Why was that in the spell?!" Alex shouted, his voice intimidating the young princess.

"I don't know! Like I said, my mum made it!" Esme tapped her chin in thought. "Then again, she did tell me this is what she did to my dad when they first met." Alex growled in anger. "Oops? What about a bit of sunshine to brighten today!" Esme waved her wand again, her voice more excited. A smiling sun appeared over Alex's head, and then turned into a rain cloud. Alex screamed in frustration.

"Okay, that's it! I'm going. If you're living here, then I'm not!" Alex stormed down the stairs, desperate to get away from the new addition to his household. The insane princess who didn't belong on Earth, whether she was half-human or not.

"Wait, Alex! I'm sorry!" Esme cried out, but before she could grab his arm, he slammed the door in her face. She sighed, and pressed her head against the door.

"Please, can you just, get me a drink?" Alex was trying to ask the man who was walking into the Stop & Slurp he was standing outside. The man, obviously upset that a teenager was asking for help, groaned and turned to the boy.

"Why can't you just go in and get it yourself?" The man asked, and Alex responded by pointing to the raincloud above his head. "Why don't you just go home?"

"Because there is a crazy person there right now and I want nothing to do with her." Alex answered. The man grunted and walked inside the shop, ignoring Alex's pleas for help. Alex frowned and looked down at his feet. He heard footsteps, and decided to try again. He looked up, and Esme stood there.

"What are you doing here?" Alex wondered. Esme said nothing. She pulled out her wand, and cast a silent spell on the rain cloud over Alex's head. It disappeared, leaving Alex drenched.

"I didn't get a choice about coming to Earth. I love Mewni. I was trying to make light of a situation I wasn't comfortable with." Esme said, looking down at her feet, and Alex's angry face softened. "But that doesn't change the fact that you didn't get a choice about having to deal with me. I'm sorry. If you want, I can go live with another family." Alex looked just about ready to forgive her when her noticed something behind her.

"E-Esme?" He stuttered, pointing at what he saw. Esme, confused, turned to what he was pointing at, and hoped she didn't. Behind her, were Ludo and his monster army.

"Hey, Ludo! How's it going? Came to see me? Aw so sweet!" Esme cooed sarcastically. Ludo gripped his staff tighter.

"That is not what is happening and you know it!" Ludo yelled, Esme looking down at him with a smirk on her face. She giggled a little at Ludo's face.

"It doesn't matter!" Ludo screamed, and pointed towards Esme. "Get the wand!"

Esme held her wand out ready to blast the monsters into the next dimension, but before she could, Alex jumped in front of her, and kicked and punched the monster that came towards them first. Esme gasped at the boy in front of her. She smiled and giggled.

"Woah! You can fight?!" Esme gripped her wand, a large smile covering her face. Alex smirked back at her.

"Yeah. I grew up with a few older brothers. I know how to fight." Alex said as he punched another monster without even looking. Esme smirked and aimed her wand at other monsters. The battle lasted for a good few minutes before all the monsters were injured, tired, and out of breath.

"You want more Ludo?" Esme tossed her wand in her hand over and over. Ludo sighed and pulled a pair of scissors out from a pocket in his gown.

"This is not the end, Princess." Ludo glided his scissors up, a portal opening where he cut. "Everyone, back in the portal!" The monsters slowly limped into the portal, Ludo following afterwards. Esme brushed some dirt and dust off her skirt as Alex walked up to her, excited, and smirked.

"That was awesome!" Alex cheered. "We were amazing!" Esme giggled at his enthusiasm.

"Yeah. I guess we were." Esme's face fell after another thing dawned on her. "I should…go back and…pack my stuff. Ask my parents for another place to stay?" Esme smiled sadly and turned away, walking in the direction Alex's house was.

"Wait!" Alex grabbed her arm before she could walk further. "I don't want you to go. I'm sorry for making you feel bad." Alex wrung his hands together. "You don't know anything about Earth yet. I should have been more understanding. I'm really sorry, E."

Esme gasped. "You called me E!" Esme jumped and ran on the spot for a while before pulling Alex into a hug. "Thank you." She whispered. Alex smiled, and hugged her back. They pulled apart and started walking home, Alex's arm relaxed on Esme's shoulder's as she gripped her wand.

"So, will more monster's come after us?" Alex questioned.

"Most likely." Esme smirked.

"Awesome."
