Disclaimer: Because the dancing pig in a tutu on the corner of a down town street scared me so much, I decided to admit that I don't own Yu Yu Hakusho or Harry Potter. Curse you Piglet the Dancing Pig!

AN One week, just like I promised Kuroi. This chapter is for her because I also promised her it would be. I make a lot of promises to Kuroi, I've just noticed. But I get stuff in return, so it's probably a fair trade. Or, close to a fair trade. This one if for you, Kuroi-chan, hope you enjoy it! [Don't tell anyone I was sending your teasers]

BTW: I know that I said there will be yaoi in this fic – and there will be. But it will be almost like a very close friendship. You can read it either way if you wish. To those I lost because of it – please come back.

Note: Yukina doesn't know that Hiei is her brother!

================================

Chapter 9

The Great Hall had already been relatively quiet because of the elderly woman now occupying the unnoticed empty seat at the teacher's table in the front of the room. But when Hiei entered and a small girl latched onto him, even the stereotypical crickets chose to remain silent.

"Yu-Yukina?!" Hiei's voice rang shocked and hesitant through the otherwise silent hall.

The Jaganshi looked unsure at whether he should run away or hug his sister back. He settled for the latter, glaring heatedly at all the rubberneckers in the room.

The Hogwarts community was silent, as to discover who this unknown girl was. Even the damn stereotypical crickets chirped not in surprise at Hiei's returning of the hug. Several members of Kurama's fan club were already plotting how to win over his love, as Hiei seemed otherwise occupied with a girl. However, all present were disappointed when their focus of attention began conversing in Japanese.

On the other hand, Hagrid – the half-giant games keeper and keeper of keys – suddenly burst into the room, feathers covering his overcoat. A flurry of whispers broke out, concerning both Hiei and Hagrid.

"Professor Dumbledore, sir!" The games keeper cried, charging up to the head table. "Sommat's been in the chickens coop!"

Yusuke shot Kurama a suspicious look, while the redhead looked up at the enchanted ceiling and hummed innocently.

"Not only that, sir – but whatever it was has been patrolling the forest as well! The creatures there are too frightened to even talk about it!"

Dumbledore murmured something under his breathed and then softly gave some introductions to the half-giant standing in front of him. "Find out what you can about it, Hagrid, but don't provoke whatever it is. It could be more dangerous than we realize."

Kurama, because of his sensitized hearing, was able to over hear the instructions, and looked indignant at being referred to as an "it". But he knew better than to say anything. If wizards had indeed been the first to fear and kill demons, they probably wouldn't hesitate in doing it again.

Meanwhile, Hiei had Yukina were discussing the latter's suddenly arrival in the wizarding world.

"~Genkai-sensei was asked to fill in as a professor here!" Yukina explained in Japanese, not being able to speak English like her friends. "~Because I'm under her care, I came so that I wouldn't be forced back into the Makai.~"

The blue haired girl beamed and led Hiei towards Kurama and Yusuke. She smiled at each of them before politely greeting Harry as well.

"Genkai-sensei also suggested that I call you onii-sama. She said people wouldn't try to hurt me if I was your sister. Well, she said either sister or lover, but I thought that sister might be a bit better for your reputation." Here, Yukina sent an almost sly look towards Kurama. "Genkai also mentioned that you probably have the entire school afraid of you already." She didn't look surprised about that fact either.

Hiei let out a sigh of relief and nodded, promising to protect his little sister. He also sent a truly deserving death-glare to Genkai, who smirked at him in return.

About five students passed out from the look that wasn't directed at them. One girl screamed and ran from the room.

As it turned out, all thoughts of killing the old physic were forgotten as Ron made an unwelcome and unforeseen approach.

"Hello," he greeted the Koorime, not heeding the warning growl coming from Hiei. "My name is Ron Weasley. It's nice to meet you." He stuck out one hand and waited, presenting himself like a show-pig at the county fair.

Yukina blinked at him before looking strangely at his offered hand. She didn't understand a word of what he had just said past hello.

"She doesn't speak English, baka!" Hiei snarled, his body temperature rising with his temper. "Scram before I fry you."

Harry grinned to himself, taking great pleasure in threats that weren't directed at him for once.

Ron shot the demon a scathing look before smiling once more at Yukina. The girl in question was now holding a quiet conversation with Kurama, much to the annoyance of said Kitsune's fan club.

Draco sat down a minute later, having arrived to dinner late due to a run in with Argus Filch, the bitter and sadistic janitor, and his cat, Mrs. Norris, who was equally sadistic but had no real reason to be bitter. Because of his lateness to the meal, Draco completely missed out on both the introduction and the would-be confrontation between Yukina and Ron.

However, as Draco was raised as a Malfoy, it didn't take him long to notice the aqua haired beauty sitting at the table he himself wasn't exactly welcomed at.

But, before said boy could be properly introduced to said girl, a certain fire demon took his "sister" by the arm and led her from the room. "Are you rooming with us, Yukina-chan, or with Genkai?" He asked in Japanese, reverting naturally back to the human language he had learned so long ago.

He didn't dare to look into the hopeful eyes that were the same crimson color as his own.

"She'll be rooming with us, of course." Kurama said, stepping up to the twins and smiling winningly at them.

Hiei scowled.

Yukina's eyes lit up. "Really?" She cried, her soft voice almost managing to create an echo.

"It's up this way, Yukina-chan." Kurama smiled, leading the way up the stairs and towards their private dormitory. "Hiei was complaining about having a room without a window, so you can have that room and he'll bunk with me."

"I'm not intruding, am I?" The Koorime asked worriedly, catching onto Hiei's sleeve and tugging lightly to make sure that she was heard.

Hiei tensed before he turned back with as close to a smile as he could get. "No, Yukina-chan. I was thinking about rooming with the Fox anyway."

===

Yusuke stomped into the dormitory and scowled darkly at Kurama, who was in the process of enchanting the window sill to be wider and more comfortable, so that Hiei might sleep in it. Hiei himself was helping Yukina settle into her new room, and was doing his best to help his sister get comfortable.

"Hey! That's not fair! Kurama, you're cheating!" He was, obviously, referring to their previous bet about Kurama trying to seduce the small Jaganshi.

Kurama chose not to comment and placed a few dozen plump pillows and a couple blankets in the window as a finishing touch.

Hiei walked into the room and inspected the newly finished window-sill. He nodded his satisfaction at how it looked and jumped up to test its comfort level.

"No, I'm not." Kurama finally disagreed, watching with amusement as two pillows that didn't meet Hiei's high standards flew out the window and burst into flames. "Hiei chose to move in with me, I didn't move in with him."

Hiei paused in his pillow selection and turned to the two in the room with him. "...Am I missing something here?"

Harry, who had just walked in, sighed. "I know I am."

"Baka!" Kurama screeched, his eyes flashing gold for the slightest moment. "Get out of my room!"

Harry looked offended and turned to leave. He spotted Yukina in the main room of the small dormitory and sat down next to her on the couch. Doing his best to remember the Japanese left in his brain after removing the translating charm he had used for three months straight, asked if the girl would like a charm so that she might speak English.

Yukina beamed and nodded.

Moments later, her voice rang through the room with a laugh that summoned the three boys still arguing in Kurama's room.

"What did you do to Yukina?!" Hiei snarled, appearing first, one pillow still in his hand. He looked ready to tear Harry to shards for daring to touch his precious little sister.

"He gave me a translating spell, onii-sama," Yukina said softly, getting to her feet and placing one hand on Hiei's arm. "He didn't harm me."

Kurama and Yusuke appeared, their eyes wide. After deciding that nothing was wrong, the two boys returned to Kurama's room to continue arguing over the rules of their bet. Hiei cast a weary glance at the two he considered decent allies and wondered if it was worth the aggravation of following them or not. He decided not to bother and instead offered to give Yukina a tour of the castle.

"But it's so late!" The girl protested, gesturing out one window to bring notice to the fact that the sun had long since set and the moon was already high in the night sky.

Hiei looked confused before nodding. "Of course, you're probably tired from your trip."

He led his sister to her room and made sure that she was contented before leaving for his new shared room with Kurama. Yusuke it seemed, was just leaving and he gave Hiei a long hard look as the two passed outside the partly open door.

"Don't let your guard down." He muttered. "You never know what that crazy fox will do."

"I heard that Yusuke!" Kurama's voice rang out.

Hiei sighed and continued into the room and into his new window. It was probably one of the most comfortable window-sills he had ever had the privilege of sleeping upon.

"Potter!" Yusuke's voice snarled. "Get to bed!"

"EEP!"

===

The next morning, Kurama approached Harry with a small smile and a slight bow. "I'm sorry for my temper last night, Harry-kun." He said softly. "But Yusuke was trying my patience and you just caught me at a bad moment."

Harry, like so many before him, was unable to deny forgiveness to the red-head. He nodded with a slightly forced but for the most part sincere smile. "It's alright." He replied. "I should have knocked."

Hiei stalked into the room a moment later, looking quite refreshed. "You're on duty today, Fox." He said as he passed them. "Yusuke was going to meet up with Hagrid about the creature in the forest, and I'm giving Yukina a tour of the castle."

Kurama smiled. "Alright. Just don't get lost, ne?"

Hiei gave him a truly disgusted look at even the thought of him being able to get lost.

"Kawaii..." Kurama murmured under his breath with a smile big enough to split his face.

===

"My name is Genkai and I am your new teacher. I know that every teacher before me has been a baka beyond all belief and reality. Don't expect me to go easy on you. I am going to re-teach you everything that you have been taught from the moment you began to learn history."

The class, a Gryffindor/Slytherin seventh year class, exchanged nervous glances before turning back to the small woman standing at the front of the room.

Next to Harry, Kurama snorted and muttered something under his breath in a language that Harry couldn't decipher. All he knew was that it wasn't Japanese... or English.

"I trust that you all have a copy of the unabridged Hogwarts: A History." The woman continued, holding up her own. "I want you all to turn to page six-twenty-two and read silently until you reach the end of the chapter."

There was a brief pause. "Mage, come up here, I want to talk to you."

Kurama lifted one red eye-brow but stood to make his way down to Genkai.

"~I trust that you're keeping track of each person with a fair amount of magic?~" The woman questioned, leaving no question about what she wanted to speak to him about. This was purely about the mission that the three Tentai were currently trying to solve.

"~Yes, but the Youkai compass doesn't work here. So we've got no real leads. After I finish planting seeds I'm going to tie their energy off and let Hiei examine them.~"

The sensei nodded. "~Don't underestimate this demon. High power bodies might reject him. Be sure to keep track of those with low energy, or none at all.~"

Kurama blinked. He had only been planting his Tracking seeds in people with high energy because he figured that the demon would end up feeding off of the plentiful supply of energy they would receive in such a body. What benefit would a low energy body have compared to that? But, the Kitsune didn't question the woman, nodding instead and returning to his seat near Harry.

The class had finished reading the chapter and class resumed.

"What you just read was the general profile of a Kappa. As you know, this creature is native to Japan. What you don't know is the demonic background. Write this down..."

Class continued on without a hitch. Genkai sighed to herself as she watched the brainless students eat up what she said. It would take a lot of work to get them to participate and try to prove her wrong.

Another sigh.

A lot of work indeed.

================================

REVIEW RESPONCES: for the selected few:

Kuroi: here's to you, Kuroi-chan. I hope you liked this chapter and I'm sorry I didn't respond to you. . Notice how I put our conversation in there? I had to doctor it up a bit, but it's basically the same. ^__^ And you know my spelling sucks! Stop nagging me about it!

Anonymous: Yes, the book thing will be revealed in time. I'm sorry I freaked you out, and I didn't actually plan to bring Yukina into this so early, but I managed to work it all out. Glad you enjoyed. ^__^

Ciu Sune: Sorry about the character bashing, but I think that's just something Hiei would do. You know, being bitter about having to baby-sit some stupid Ningen and all. And, I'm sorry about the shortness.

Flamin: Don't worry; I'm almost as clueless as you are about Japanese. The only reason I can fake it so well is because I've somehow managed to acquire some anime in its original Japanese and pick up some words and stuff. That, and I have some friends who would kill me if I used the language incorrectly.

Bakagami101: Some good Yusuke/Hiei fics? Hmm, let me think – to tell you the truth I've only read about three of said paring, and written one. "Blood Soaked and Honor Bound," by Mina Lightstar is really good. "Strangers" by Dark Dreaming is really good [yes, that was a shameless plug]. And "Life and Love" By Crystal is really good. And yes, of course I love Gundam Wing! 1x2 is my favorite pairing, but I also like 5x2. ^__^

__: I might use that idea [note that you didn't put in a name so I don't know what to refer to you as] about Hogwarts not knowing about Yukina's relations to Hiei. It's got promise.

REVIEW PLEASE!
