This is Magic: Ereri Harry Potter AU! Fanfiction

Chapter 2: Arrival

When Eren awoke, he didn't expect to see what was before him. Actually, he didn't expect to see a lot of things. An elephant would be one of these things, for example. The Great Wall of China would be another. However, what was in front of him was neither a large mammal nor was it a wonder of the world. It was, in fact,  two very large, curious blue eyes. The twelve year old flinched backwards.

"Um...." Eren said, avoiding the person's stare nervously. "Can I help you...?" The cerulean eyes blinked once, twice, before widening in realization and disappearing from Eren's view. The owner of said eyes jumped backwards, a light dusting of pink covering his face in embarrassment. 

"Oops! Sorry! Y-you just looked familiar, so, um, I just wanted to see your face. I'm not a creep or anything, I swear!" the kid replied quickly. Eren smiled at the flustered boy in front of him. Now that the boy was farther away, the brunet realized that he was the one who ran through the wall before him. Eren recognized the light blue sweater that dangled off the kid's shoulders and completely covered his hands. He also had silky blond hair that framed his face rather well. Even for a small kid, the boy had a large amount of baby fat still on his face, making him look exceptionally young. If Eren hadn't known better, he would've thought that the boy in front of him was too young to be on the Hogwarts Express. 

"It's alright," Eren laughed, looking at the other boy with curiosity. "I'm Eren Jaeger, first year. What's your name?" The blond immediately relaxed at Eren's soothing and friendly tone of voice, taking a seat opposite of the brunet and letting out a small breath.

"My name is Armin Arlet. I'm a first year as well," Armin introduced politely, folding his small hands in his lap. Eren noticed the small cage covered in a dark green cloth next to Armin's small frame. 

"What's that?" Eren asked, pointing to the cage. Armin looked down at what Eren was referring to before smiling and lifting the cover up. The brunet was surprised to see a minuscule ball of feathers perched on a bar of the cage. It rose and fell with its breaths, and  a few light brown feathers could be seen falling to the floor of the cage. 

"This is my companion, Bertholdt," the blond announced proudly. "He's a burrowing owl. The smallest species of owl on Earth, did you know? He had to be imported here from North America! They usually grow to be ten inches tall, and they're very friendly towards humans. They're even smaller than squirrels! Of course, since they're so small, they eat mainly bugs," Armin rambled on and on, clearly knowing a lot about Bertholdt's species. The owl seemed to huff, as if it had heard its owner give this speech countless times. Eren muffled a laugh behind his hand. Seeing Armin's expressiveness for the first time, it was easy to tell that he was quite intelligent.

Eren settled back into his seat, happily resigned to listening to Armin's speech, when the door to Compartment 104 opened once more and a girl slid inside. She wore a white dress with matching shoes, but both articles of clothing had scuffs and dirt on them, suggesting that the girl had been hurrying to reach the train. Eren noticed the girl's long black hair and thought of the boy called Levi for a split second before pushing him to the back of his mind. The girl turned around and bowed slightly to them.

"Hello, my I am Mikasa Ackerman, and I'm a first year. May I sit with you during the ride to Hogwarts?" the girl asked quietly, looking at the other first years with sharp black eyes. Eren glanced at Armin, who shrugged.

"Sure, why not?" Armin accepted happily. "You can sit next to me." The blue-eyed boy patted the spot on his left. Mikasa nodded her head slightly and took a seat. Eren noticed that she had no belongings, either.

Most of the train ride was spent by getting to know one another. While Mikasa didn't speak much, she did tell the new acquaintances that she lived with her mother near Karanese. Her mother is a muggle, and her father was a wizard.

Armin informed them that he was completely muggle-born, and that his parents died in a car crash when he was young. He has lived with his grandfather ever since, who is a very well-educated and wise man. From him, Armin picked up reading and strived to learn as many things as he could. When he turned seven, his grandpa found him floating above his bed. That was when they first discovered that Armin was a wizard. 

 Eren explained that he was a half blood; his father's parents were both muggles, but his mother is a pureblood witch. They used to live in Germany, but when his mother's parent's found out that she had married a mudblood, they threw her out. Eren's parents then moved to Shiganshina and gave birth to Eren. Eren has played Quidditch ever since he was little. When Mikasa heard the brunet talk about the sport, her black eyes lit up. 

"I play quidditch, too," she murmured. Eren grinned and wriggled excitedly. 

"Really?? What position do you play?" he questioned. 

"I'm a Beater," she replied. 

"Wow, really?! I would have taken you for a Chaser! That's what I am, by the way. I've always wanted to be a Seeker, but my eyes can't pick up the Snitch's movements," Eren complained, slumping back in his seat. 

The trio talked like this for hours, and the sun slowly started to creep towards the horizon like honey running down its jar. The candy trolley passed by their compartment a few times, and Eren decided to buy a chocolate frog and a pumpkin pasty. It wouldn't be too bad to spend just a little bit of his galleons on candy, right? Eren learned that Armin was hoping to join Ravenclaw, while Mikasa had no preference whatsoever. Eren agreed; he was content just to be able to attend Hogwarts. During a lull in the conversation, Armin glanced out the window and gave a shout of surprise, jumping up out of his seat. 

"Look! It's the castle!!" he exclaimed. Eren stood as well and pressed his face to the glass, eagerly searching for Hogwarts. Just past a rolling hill, the towers of the castle could be seen. As the train rolled along further, the magnificent lake was visible in front. 

"Wow..." Mikasa breathed, clutching the hem of her dress. Eren's hands tightened into fists as he gazed at the beautiful sight. The train slowed to a crawl and let out a hiss of steam before stopping with a jolt. Eren snatched his bag from above and shot out of the compartment. Other students were sticking their heads out, looking around lazily as if they had just awoken. Armin and Mikasa trailed behind the teal-eyed boy, who was blazing a path to the nearest exit of the train. When he finally reached the doorway, Eren leaped out and landed heavily on the cobblestone station floor. 

An extremely tall man with blond hair and a beard and moustache ambled over. In his hand was a lantern, already lit in anticipation for the darkness that was soon to come. Oddly, he sniffed the air as the students spilled out of the train's doors. 

"Hmmm," the man hummed. "My name is Professor Mike. Welcome to Hogwarts School of Witchcraft and Wizardry."
