I got some of the ideas for the story from the animate & manga series Vampire Knight.
Sega owns the characters, names, etc. Whoever owns Vampire Knight owns the story similarities.
The Meanwhiles are for when we're switching the point of view between the guys & girls.
There was an underground mansion where, in a room lay three vampire brothers; a black & red hedgehog named Shadow, a silver hedgehog named Silver, & a blue hedgehog named Sonic. It was midnight when Sonic suddenly got up, walked to Shadow's bed, poked him, & said, "Shadow. You awake," Shadow opened his eyes & glared at Sonic as he continued, "What did Dad say about the academy? When are we going?"
Shadow replied, "We're catching a ferry tomorrow morning at 8 that's going to take us to Moonstone Academy's personal dock. The academy is, like, built on this mini island. There's just the academy, a nearby town, & a beach. It's pretty much cloudy all the time everywhere except the beach. That's the only place that's sunny & warm.
As for the academy itself, Dad showed me pictures of the school, told me about the curriculum, teachers, classes, etc. Then he asked me if it was Ok."
"What did you say after that," Sonic pressed.
"I said I didn't care. Whichever way was fine. Then he groaned, & I added 'Though, I would like to go there.'"
"So it's an awesome place?"
"Tolerable. But, as you know, me saying that is pretty good. There'll be other vampires there; a few other purebloods & some aristocrats, but we'll be mingled up with the non-vamps too when we go to class during the day."
Sonic smiled & said, "Mmm. Real dinner every night, instead of these boring blood tablets."
Shadow smirked as he pulled pistol called 'Bloody Rose', a deadly vampire killing weapon, out from under his pillow & said, "Dad thought you might think of some crap like that. So, he told me to keep you guys from embarrassing the family. Cause' you see, the chairman strives to create a peaceful co-existence between vampires & non-vampires. In other words, he trying to patch up the non-vamp & vamp relationship lost in the Old War."
Sonic yawned as he walked back to his bed & said, "Whatever. As long as there are girls." Shadow's only response was a groan of irritation & disgust.
Meanwhile.....
There was another mansion in the middle of a forest, where three non-vampire sisters lay in bed; a black & purple hedgehog named Rose, a lavender cat named Blaze, & a pink hedgehog named Amy.
"... & so the academy sounded pretty good. I'm kind of looking forward to going there," Rose said as she concluded her description & opinion of the new school they were going to.
"Hmm," Blaze said, "I'm guessing Amy's going to do a lot of flirting since the guys there are so pretty."
"Speaking of flirts," Rose said, "Dad told me to stop you from making yourself an idiot over the guys."
"Hmph," Amy said, playfully trying to sound hurt, "You guys act like that's all I've ever done & will ever do."
Rose smirked & said, "Umm, well, if we base every-"
"I'm going to bed," Amy threatened.
"May your dreams be filled with visions of the guys from the academy," Rose playfully prayed for Amy.
In response, Amy just threw her spare pillow at her in return & said, "No, seriously Rose, you need to have a future with somebody, or else you'll be doomed with the fate of becoming an old maid. Now's your perfect chance to try to fins that someone. Remember in 8th grade when that guy said he liked you, & you just laughed at him. That was mean."
"Oh, come on Amy," Rose said exasperatedly, "I laughed at how ridiculous he was because I've never met him before. And besides, why do you remember stupid things from 4 years ago?"
"Amy," Blaze interjected, "you should just wait for Rose to see someone at the academy. I really doubt that she & someone else won't find each other interesting."
"You two need to get a life & some sleep. We have to catch this ferry at 7 tomorrow, so that means we've got to be up at 6," Rose said, at this point clearly irritated.
"Oh Rose," Amy said teasingly, "Planning tomorrow out as usual. Though, I'll only be bothered when you start planning out your entire life." The girls all turned away from each other & laughed.
Early the next morning, the girls all woke up at 6, dressed, ate, & got their bags ready at the door. "Ready girls," their mom asked.
"Ready," they all answered in unison.
At the ferry dock, they saw a few of their friends, including a white bat named Rouge. Blaze walked over & said cheerfully, "Hey Rouge! Are you going to the academy too?"
At those words, Rouge's shoulders slumped as she said glumly, "No, my parents think that I'll become a flirt because of the guys there," she lowered her voice as she continued, "And, my parents think it's too pricy."
"Oh. That's too bad," Amy said as she forced a weak smile, "We'll tell you about it though. Email & maybe postcards."
Rouge just returned the smile as she said, "Well, I'd better get going. I only came here to see my grandma off. She's riding a ferry home."
"Ah," was all Rose said for comfort as they watched Rouge walk away.
Their mom sighed & said, "Let's get going, the ferry's about to leave."
"K," Blaze murmured.
At the ferry gate, their mom said a lot, "Remember to call me. Do you have all the forms? I love you!"
The girls just said bye as they rushed inside, eager to escape the embarrassment.
On the ride to the academy, the girls cheered up a little. By the time the ferry landed, they were in high spirits. "What time is it, Rose," Blaze asked.
"10 AM," Rose answered as she led the girls toward a yellow rabbit that looked in charge. "Excuse me sir, but we're going to the academy on this island. You wouldn't happen to know how to get there, would you?"
The rabbit smiled kindly & said, "Yes, I do know how to get there. I'm the headmaster, Headmaster Kaiyen. You must be one of the girls attending the academy."
Rose smiled & said, "Yes, we are."
"Good. You see that white cat over there? That's the Attendance Secretary, Ms. Senri. You just hand over the forms to her, she'll look you up, & when you're found in our list, you're free to just hand out in the docking area until everyone is accounted for, which will be about 11. Promptly at 12, be at the parking lot, where there'll be a bus to take you to my academy. You'll receive further instructions from the Sun Dormitory's tenant, Ms. Ichiru I suggest you hurry over there while everyone is ignoring her."
Rose smiled once again & said, "Thank you Headmaster Kaiyen! Oh, by the way, my name Rose, this cat is my sister Blaze, & this hedgehog is my other sister Amy."
"I'll remember," he smiled as they walked away toward Ms. Senri.
When they got there, she smiled & said, "I'll take your papers & find you as quick as I can."
Rose smiled, yet again, as she said, "Thanks." It was no more than a few minutes before Ms. Senri had found the girls & filed away their papers.
"Ok, you're good to go," she smiled.
"Alright, thanks," Blaze said as she tugged Rose away before she could smile again.
As they walked, they heard Ms. Senri mutter to herself, "Oh, God," as a swarm of girls ran to her.
But Blaze was freaked when she asked Rose almost hysterically, "What were all the smiles for?!?"
Rose, this time, smirked & said, "For a good rep. with the Headmaster & everyone. Muahaha," Rose added as an retarded evil laugh.
By the way, Amy, Rose, & Blaze are NOT going to be like the fan girls from the manga. Though, Sonic might remind you of Aido. You also might've recognized some of the last names too. And Rouge is just going to show up every now & then when she's convenient & needed.
