Prologue

"SLYTHERIN!" The hat on her head boomed after a moment of contemplation. I watched as the girl came to sit down next to Parkinson. That was the last girl to sort, and after that, the big feast began. They started chatting up some conversation about something, but my attention wavered off them. It was the boy sitting next to them that puzzled me.

"Still staring at the Slytherin Prince again, Serena?" my friend Mina asked with a mischievous grin.

I tried to play dumb, and drank some punch. I didn't understand why they didn't just by soda or something, this stuff was awful. "I am not," I lied, eating some spaghetti to get the taste out of my mouth.

She rolled her eyes, unconvinced when someone tapped her on the shoulder. It was a lady dressed in deep purple robes that matched her hair. Yeah, you heard me. Purple hair. I'd never seen her before, was she a new teacher? Beside her was a small cat, I checked to look at the teachers and saw McGonagall sitting there. Nope, this seemed to be a real cat. But, peculiarly, it had a moon on its forehead. It noticed me looking and jumped on to my lap, purring while I petted it. I didn't mind cats; they were cool. However, that symbol on its forehead was just unusual. I'd never seen anything like it.

My mind drifted to Harry Potter; the boy-who-lived in case you've never heard of him. He also had a lightning bolt shaped scar on his forehead. Was the moon a scar for the cat as well? It didn't look like it; it looked like the fur was yellow and had grown into that shape to resemble a moon.

The owner of the cat gave a slight cough and the cat's eyes perked up and went to go beside her. "Sorry, about that." She said to me hesitantly. "Luna's usually a controlled cat," upon hearing her name the cat meowed and seemed to look up at me and smile. I blinked; yup. Definitely looked like a smile. How odd. "I'm Minako's cousin," she introduced herself, and put her hand out to shake with me. I looked at Mina, confused. She was my best friend; she would have told me if her cousin was coming.

"Excuse me; I don't think I've ever met you." Mina said with the same confused look on her face.

The girl's eyes seemed to narrow a little and glow. "You must not recognize me because of my hair cut. It's me, Hotaru." She said in a weird, silky voice.

All of a sudden, Mina's face smoothed out and she smiled. "Oh, of course!" she said getting up to give her cousin a hug. Her cousin was probably older than her, but she was also shorter. "I was wondering when you were going to come," she exclaimed with a smile. Then she turned to me, "This is my best friend, Serena Williams. Serena, this is my cousin from Japan, Hoshina Hotaru, she's learning to become a wizarding teacher and is going to stay at Hogwarts for a while. Sorry for that, Hotaru, it completely slipped my mind."

"Nice to meet you," I said shaking her hand. This wasn't like Mina, she never forgot anything.

"Nice to meet you too," she said and turned to Mina. "It's okay, but I just came to say hello, I have to go and get my things prepared for tomorrow."

Mina smile and said, "Of course, maybe I'll see you tomorrow in one of my classes." I tuned out of their conversation as they said their goodbyes. The Headmaster was looking in our direction, his attention focused on Mina's cousin. He seemed to catch my eye and gave the briefest smile before stepping up to the podium.

The hall quieted down and I noticed that Mina had sat down beside me and was rubbing her temples. "Something wrong?" I whispered to her.

"No, just a little headache. I'm probably just hungry," she said with a slight smile.

"When are you not hungry?" I asked and we laughed.

"Welcome, welcome! To another year at Hogwarts," The Headmaster's voice rang out. "Now I would like to say a few words before all become befuddled with our wonderful feast. First I'm pleased to welcome Professor R. J. Lupin, who will be teaching your Defense against the Dark Arts this year. Good luck, Professor." He said and a man in a suit stood up as we clapped. Anyone who had been teaching that class for the past two years always quit. This man needed all the luck he could get. I saw Granger say something to Potter and he nodded. Seeing I was looking, she caught my eye and smiled. I slightly smiled back, but brought my eyes back to the Headmaster.

"…than our own, Rubeus Hagrid," He paused and everyone started to clap again as he stood up. I stifled a giggle as the table shook when he stood up. He was actually a pretty cool teacher. Apparently the Golden Trio must have thought so too, because they were cheering and clapping the loudest. "Finally, the ministry has informed me that Hogwarts, until further notice will be play host to the Dementors of Azkaban ," whispers broke out as soon as he paused, "Until such a time as Sirius Black is captured."I saw Potter pale slightly.

"The Dementors will be stationed at every entrance to the grounds. Now, whilst I've been assured that their presence will not disrupt our day-to-day activities; a word of caution." His voice went serious and he stared at Potter. "Dementors are vicious creatures; they will not distinguish between the one they hunt for and the ones that get in their way. Therefore, I must warn each and every one of you, they have no reason to harm you.

"It is not in the nature of a Dementor to be forgiving; But, you know, happiness can be found even in the darkest of times," he waved his hand and beside him, a candle went out. "When only one remembers, to turn on the light," The candle flickered on again. ©

He added some more and let us continue on with our feast. I noticed Potter was just pushing food around his plate. I'd heard that a Dementor had come on the Hogwarts express and he had collapsed or something because of it; Malfoy had said he had fainted. Were they really that terrible?

Yup. New story. I seriously have nothing else to do with my time :P It's a cross over with my faoriteest show eva since I was 7 yearas old :D hope you like + if you haven't guessed by now, it takes place in the 3rd year of HP
