DISCLAIMER: I don't own Harry Potter or Sailor Moon.

"Oi." A girl with short, badly cut blonde hair poked her head into the compartment. "Mind if my friend and I sit here? I think everywhere else is full."

Michiru Kaioh looked up from her book, nose wrinkling at the sight of the girl's plain robes. Clearly she was from a lower-class family, and the Kaiohs did NOT mix with their sort. "Who, may I ask, are you?"

The girl blinked, taken aback. "Er…Haruka. Haruka Tenoh. You're…?"

"My name is Michiru Kaioh. Perhaps you've heard of our family—at least, you'd better have," she sniffed. To her surprise, Haruka grimaced.

"Oh, yeah, you're one of those stuck-up pureblood prats. Seiya warned me about you. Think you're better than me because I'm Muggleborn."

"You're a Mudblood? That would explain it." Michiru edged away from the door as if Haruka was contagious. Haruka frowned, leaning against the side of the compartment.

"A what?"

"Mud-blood," Michiru said slowly, as if talking to a young child. "It means you have filthy blood running through your veins because your parents are Muggles, lowest of the low."

"Don't you bring my parents into this!" Haruka stepped forward, fists clenched at her sides. Michiru ignored her.

"And what happened to your hair? Not that you're pretty anyways, but it certainly doesn't help your appearance." She smirked as the blonde's hands tightened even further and her scowl deepened.

"I cut it myself, if it's any of YOUR business. My parents want me to act like a girly-girl, but I'm a tomboy. I wouldn't wear a dress if you paid me."

"Poor breeding to go with everything else. I'm shocked I didn't know you were a Mudblood the moment I saw you." She glanced down at her book. "Now go away."

The next thing she knew, she was being shoved back against her seat as Haruka's hand gripped her collar. She squeaked, both scared and indignant. "Get off of me, you filthy—"

"Who do you think you are?" Haruka snarled, giving her a rough shake. Her other hand, to Michiru's alarm, was drawn back in preparation to strike. Up close, it was impossible to notice that Haruka's eyes were really quite pretty: A deep teal color that was almost more green than blue. She swallowed hard as her heart gave a sudden lurch. What in the name of Salazar…?

"Haruka!" A boy with dark hair tied back leapt through the door and dragged the blonde off of Michiru. "What are you doing? You'll get in huge trouble, we're not even at Hogwarts yet—"

"This prat—called my parents dirty, lowly—said I'm a Mudblood—" she growled, repeatedly trying to yank free of the boy's grip. "Seiya, gerroff of me!"

"She's a high-ranked pureblood, what d'you expect?" he grunted. "I told you about their type." Still restraining Haruka, Seiya glanced over at Michiru. "Kaioh, am I right? I believe we've met briefly—you remember my two brothers and Kakyuu from the party at Malfoy Manor last summer?"

"Oh, yes, your Mudblood-loving family." That was only half-true; as far as Michiru knew, Kakyuu's family, the Kinmokus, held perfectly respectable views on blood purity. It was common knowledge that the Kou clan was only around because they served as guardians to the Kinmokus. He scowled.

"C'mon, Ruka, let's go. I met a really nice bloke and he said we could sit with him. What was his name—Bill….Weasel or something?" Still talking, Seiya steered Haruka out of the compartment, shooting Michiru a glare as they went. After the two had left, Michiru exhaled shakily and slumped back against the seat. Haruka looked as though she'd been about to beat Michiru to pieces, and although the aquanette knew she could easily best the blonde in a wizard's duel, physical contests had never been her forte. Again her mind flashed back to how she had reacted upon seeing Haruka's eyes. Her cheeks warmed, and she snorted, picking up her book.

Filth. That's all they were.
