A. N.: This is story is the result of an RP I made with crona-is-ready-to-deal-with-this in Tumblr and it was adapted to fit a fanfiction format. The thread itself is nearing its completion, so we decided to share with others, because it managed to be such an interesting crossover! In this AU, Crona is a student at Echo Creek High School and doesn't have any of their canon powers (or do them?). Hope you enjoy!

Crona adjusted their backpack as they shuffled down the hallway, their head hung low. They tried to avoid eye contact with any of the teens who hanged around in the hallway. They tried their best to be as invisible as possible, their existence shouldn't bother anyone. They winced as they accidentally nudged a couple who were locked in a lip embrace, who thankfully ignored them. Why did this hallway seem so long? They just wanted to get home.

BAM!

They winced as they crumbled to the ground, having bumped into a girl with long blonde hair and hearts on her cheeks. They quickly grabbed their papers that had scattered all over the ground. "I'm…s-sorry…"

The girl looked at them with huge, sparkly eyes and said, "It's you, I finally stumble upon you!" She said, smiling at them and placing her hands on her cheeks.

Crona jumped a bit at the girl's gleeful expression. Wait, they knew who this girl was. It was Star Butterfly. She was a pretty big deal at the school. Many unexpected, almost 'magical' things happened whenever she was around. That was probably why Crona hadn't officially met her yet. They hated surprises.

What on Earth was she doing talking to them?

"Um…y-you must be mistaking me for someone else…." they said quietly, averting their gaze, hoping that she would lose interest in their boring ways.

"No," she said, still with her smile plastered while shaking her head, "you're definitely that quiet kid that always sit in the back corner of the class! I've always wanted to talk to you, but you always leave before I can talk to you. Crona, ain't it?"

She knew their name? How did she know that? Crona always did whatever they could to make themself as invisible as possible. Star wasn't imagining things, Crona always left class as soon as it ended on purpose. They just wanted to get through classes and go back home as fast possible. Because of this, they didn't have any friends, but they didn't have any enemies either. They had even managed to avoid getting called on by the teacher. How did this super popular girl manage to not only see them, but know their name?

"Y-You…..You wanted to talk to me?" they said, still refusing to look at the girl in the eye, "I…uh….I don't mean to be rude, but why? How do you even know my name?"

"I have a list of all people in the class." She showed them a piece of paper titled STAR'S SUPER AWESOME LIST OF FRIENDSHIP. It was basically a copy of the teacher's call list but for each name, there were stars besides it. Everyone in the class had at least one star, even Brittney for some incomprehensible reason. Marco had more stars than anyone else, though. Everyone had theirs, except Crona. "My aim is to make friends with everyone and you were the only one without a star." She pointed to their name.

Ah, so that was how she knew who they were. They were a means to her end. That made more sense. She identified them by process of elimination. She wanted to be their friend so that-

….wait…

SHE WANTED TO BE FRIENDS?!

"Oh well, uh…" Crona whimpered, starting to sweat profusely. "Um…s-surely you can overlook ONE classmate? Trust me, I am NO fun to be around. A-And I've heard of you, Ms. Butterfly. Y-You're a super fun person. I-I would bore you to tears!"

"Nah…" she waved her hand at them and continued, "I want to spread the power of fun to everyone, don't worry, with me there's no bad time!" She held her wand above her head. It started to glow and it fired a pink shot in the air. Round-shaped bunnies of all colors started to rain right over Crona.

Their only reaction was to squeak in terror as they were suddenly pelted with little bunnies. They quickly inched away from the magically transpired animals and looked back at Star. "U-Um, I-I'm sure you're a very fun person Ms. Butterfly, b-but I'm afraid I'm a lost cause. There hasn't been one day of my life where I've ever had fun. I just…can't. Plus, I kind of make it a point to not have any friends. It's better that way for everyone."

"There's no such thing as a 'lost cause', Crona. Look at Marco, he was such a lost cause when I met him and now he's almost asking Jackie Lynn Thomas out." She pointed to Marco.

Marco hyperventilated. Jackie was storing her things in her locker and didn't notice the sweaty boy behind her. He stood behind her, waiting for the right moment to finally ask her out.

At any moment now…

"Use this to get courage, Marco." Janna came from behind and dropped a spider on his shirt. He started to scream and jump, trying to get rid of the spider. Jackie finally turned around and saw Marco running around like a monkey on fire. She looked at Janna and, as if reading her thoughts, the other girl replied, "Don't worry, the spider isn't venomous."

"But is it poisonous?" Jackie asked.

"I didn't think of that."

Crona could only shudder as they took in the chaos that was happening among Star's friends. People were just so confusing to them. They didn't know what they would do if someone came up behind them and put a spider in their shirt. It would be a nightmare! Why would 'friends' do that to each other? And who cared if Marco was about to ask a girl out? Crona didn't want friends, let alone a girlfriend!

"Weeeeell, it's still a case in progress and he's been improving ever since he met me. He couldn't even stand beside her and now look at him. Just a few more weeks and he'll ask her out." She laughed. "But, Crona, remember of the poem we saw in the last literature class: no man is an island. All you need to do is to let S. S. Funtime come alongside your harbor." She said, moving her wand as if it was a small boat. "And," she fired her wand at her own face; after the magic dust settled, she had a captain hat on her head. "I'm the captain of S. S. Funtime!"

They turned to face Star, ready to reject her again, when she suddenly brought up the poem in the literature class they shared. They shifted a bit in their stance, unable to meet her gaze yet. "Y-Yeah…I remember the poem. I….I like poetry. D-Do you like it?"

"Of course! I mean, all Mewni poetry is either singing praises to the queen or celebrating crushing skulls of monsters while sitting in a throne made of their bones. Here on Earth there's so much more! Poetry that talks about a lot of things, feelings, victories, tragedies, even the weather! I could never imagine a poem about the weather not even in my wildest dreams!" She said, while Marco's screams provided the background noise.

Crona couldn't help but smile a bit. Mewnian poetry sounded a little too intense for them, but they enjoyed seeing Star getting so excited with the subject. Very little things in life brought them joy, so they treasured the art of poetry greatly.

They reached inside their black backpack and pulled out a wrinkled piece of paper. "I uh….wrote this last night. W-W-Want to see it?"

"Of course, let me take a little read." She smiled, holding both hands together.

"STAAAAAR! I THINK IT BIT ME!" Marco cried looking in concern at a red spot on his hand.

"Just a little moment, Crona." Star smiled at them. She pointed the wand at Marco. She glanced at Crona and said, "I wanna try something new. In Earth's movies, the magicians speak Latin while doing their spells, so I want to try it by myself… Aranea becomus!"

A beam came out of the wand. But instead of solving his spider business, it transformed Marco's head into the head of a spider. He climbed in the wall, either running out of fear or confusion in the direction of the gym, followed by the screams of scared students.

"Oh my goodness, I said Aranea becomus instead of Aranea begonus!" She handed a small magical bunny to them and said. "I'm sorry, I have to solve this. I can read your poem tomorrow. Take this rabbit as a gift from me. By-bye!" Then she dashed after Marco. "Marco, wait!"

The small, fluffy animal startled Crona. They never had the opportunity to hold such creatures gently and, having one of them placed in their hands, made them feel strange, even afraid of hurting such creature. They could drop it any second! They looked in shock as the girl ran after Marco. Despite the chaos of it all, they couldn't help but smile a tiny bit. They looked down at the bunny again, this time feeling uncharacteristically optimistic. They had never been given a gift before. Why had she given them one? Why was she being so nice to them?

They quietly walked out of the school and let the bunny go free. The little creature was fluffy, and they liked fluffy things.

But Ragnarok would never have let it live.

Trying desperately to wipe the sweat pouring from their face, Crona took a deep breath before they entered their home. I'm late, I'm late, I'm late, they mentally moaned as they tip-toed if they were lucky, she wouldn't-

"Geheheheh, you're late Crona."

The teen bristled as they heard an unkind voice address them. They shivered in fear and sank in on themself. "R-Ragnarok?"

The one called 'Ragnarok' grinned a wicked grin. "Geheheh. Mom's gonna kill ya~! Mom's gonna kill ya~!"

"S-Stop it…" Crona moaned, fearing that the mean teen's words were true. "I-It's not like she knows I'm-"

"Crona."

The teen jumped, causing Ragnarok to laugh even harder. "Ooooh, you're gonna get it! You're in sooooo much trouble!" he screeched in delight.

Crona sighed as they slowly made their way to the basement door where they knew their mother was waiting for them. "Why do you enjoy my suffering so much?"

"Cuz we don't have cable," Ragnarok said with a shrug.

The pink-haired teen drudged down the dark, narrow stairwell that led to their basement a. k. a. Medusa's lab. How appropriate for a place Crona often associated with Hell.

Once they reached the bottom, they were greeted by the sight of their mother feeding her snakes. The lab itself wasn't very well lit, one couldn't see everything that was inside it from just a glance. But the most visible thing was the vat containing her snakes. They were all large, but came in different shapes and sizes. They slithered in a glass deep embedded in the ground.

"L-Lady Medusa…."

"You're home late today Crona…."

"S-Sorry…" Crona said, bowing their head in shame. "I-It won't happen again…"

"Why did it happen this time?" Medusa asked. She hadn't turned to face her child yet.

Crona fiddled with their fingers before looking away. "I uh….was reading some poetry and lost track of time…."

Medusa paused in her feeding. She hummed to herself as she finally turned to stare down at her child with her gold, piercing eyes. "Odd. You've never done that before."

Crona gulped and shrank back. "I-I-I just lost track of time….I-I-I'll never do it again! I'm so sorry!"

"Mhmm," Medusa hummed, leaning in close to the teen's face. "So….Ragnarok. Why don't you tell me what actually happened today?"

Crona gasped.

"Crona made a friend today!" Ragnarok's voice chimed in, full of delight.

"No I didn't!" Crona wailed.

"With a girl!"

"Stop it!"

"And not just any girl! That Star Butterfly girl from that weird Mewni country!"

Crona practically bit their nails. They looked at their mother with shaking eyes. "S-She tried to be friends with me, but I said no!"

Medusa watched the exchange with concentrated eyes. A smile spread across her face. "Now why would you say that, Crona? I think it's delightful that you made a new friend."

This only caused Crona's fear to grow. "R-Really….?"

Medusa nodded. "Yes. In fact…why don't you invite your little friend over for dinner tomorrow night!"

Crona's heart plummeted to their stomach. "N-No, wait-"

"Don't by shy Crona!" Medusa said. "The girl wants to be your friend! It's only right that you repay her kindness!"

Crona began to shake again. "N-No…Please!"

Medusa tsked at her child's protests. "'No'? Crona, you know how much I hate that word." She placed a hand on the child's shoulder…before quickly moving it towards their neck. She stared the teen down as she firmly pushed them against the side of the tank that held her snakes.

Crona squeaked in terror as they desperately grabbed on to the hand that held their neck. They began to shake as they looked down in fear at the large snakes that were now eyeing them ravenously. "N-No! P-Please Lady Medusa! Don't-"

"Invite Star Butterfly to dinner tomorrow night. Understand?" Medusa said, a confident smile etched across her face.

Crona's lips began to quiver as tears began to appear in their eyes. They whimpered as they lowered their head. Finally, they nodded.

Medusa gave a satisfied smile before releasing her child. "Good. I'm going to make my famous pasta! Oh, your new friend will have the night of her life!" The woman said as she practically skipped out of the basement, leaving her child to make themself into a ball, whimpering in despair.
