I don't own Yu Yu Hakusho or Harry Potter

Ch.1

Yusuke yawned as the cold air of the Spirit World shot through him. Botan had literally burst into his room at six in the morning and starting ranting about the new case that Koenma had assigned him, although she had yet to say anything that would actually clue him in as to what the case is. His all too hyper fairy-girl of an assistant had then whisked him away to Spirit World where they were currently standing outside the main gate; freezing their asses off Yusuke might add. If these people were in control of the whole world then why couldn't they do anything about the temperature?

"I'm sure the others are already here," Botan spoke up while urging Yusuke forward. It took them ten minutes to navigate their way through the halls of Koenma's office-like building.

"Hey guys," Yusuke called when they entered Koenma's main office and he saw his friends already there. He was also surprised to find the newest members of their group there as well. A few months ago a group of human teenagers had been kidnapped and it had been the Reiki Tantei's job to rescue them. In the end the teens had walked away with some powerful abilities and a few of them had chosen to stay in Japan under the tutelage of Genkai; they were Erika, Stephanie, Jessica, Jamie, and Yami, although none of this explained why they were here now.

"Koenma, before you start," Kurama spoke up. "Could you explain why the five of them are here?" Kurama pointed to the humans that Yusuke had been mentally question.

"That has a simple answer," Koenma responded, his high and mighty attitude never leaving him, even in his toddler form. "It is because Genkai has taken up a teaching job."

"…" there was a pause through out the room.

"Alright how does grandma's educational career tie into any of this," Yusuke asked, surprisingly keeping his cool. When it came to the prince Yusuke's fuse was very short.

"Well this is going to take some explaining, so please don't interrupt me until I'm done, but the school she will be teaching at is your next job assignment.

"What is this," Kuwabara exploded. "First it's babysitting and then it's school, how many absurd cases are you going to give us."

"I thought I asked you to wait until I finished speaking," Koenma sighed. "To put it simply it's a wizarding school. Probably not like the kind you see on T.V, although the pointy hats are similar. Anyway, Genkai has posted for a teaching job at a western school that has been having some trouble and you all are going to accompany her as students."

"A western magic school?" Kurama questioned. "I thought you manly stayed away from the matters of wizards, especially foreign ones."

"Well, that's the trouble I was talking about," Koenma answered. "It seems that one of their dark lords, Voldemort, has been gathering a following of demons, creating quite a stir. He is manly targeting one of the students at Hogwarts, the school you will be attending. The bays name is Harry Potter and if you stick close to that boy you are bound to run into Voldemort sooner or latter." Koenma then continued on to explain about the details of Hogwarts and the wizarding world.

"That still doesn't point out why they are coming along," Kurama pointed out when Koenma finished speaking, once again indicating the humans that had remained silent throughout the entire meeting.

"Where else are they going to go?" Koenma asked him. "Genkai's going to Hogwarts so naturally they have to go with her." This made sense but it still left some rather debatable issues.

"They are going to be in danger," Kurama noted.

"Yes, I can see how any personal relations you have with them might cause some problems." As he said this Koenma's eyes slid over to Jamie before quickly returning to rest on the fox, the gesture did not go unnoticed. "So I suggest you pretend that you don't have those relations."

"That still doesn't explain why the old bat has to teach at this school," Yusuke exasperated.

"It's a bit of a long explanation," Koenma started to explain. "To put it as simply as possible the position of the Defense Against the Dark Arts teacher is usually open every year, seeing as how they can't seem to hold on to a teacher for longer than that. However this year someone from the Ministry of Magic, Professor Umbridge, has been assigned the job. Now the Ministry of Magic is the Government of the magical world and they are at slight odds with the school. Professor Umbridge has been assigned the position of teacher to try and keep the students from learning any useful magic that they could use to go up against the Ministry. You see?" The whole group just nodded its head, knowing it was best not to interrupt the leader as he rambled on. "So in countenance the school has decided to add a new course entitled Practical Magic, which Genkai has volunteered to teach. It all works out; they needed a teacher and we needed a way to infiltrate the school and keep an eye on Voldemort's main target." At this point Koenma waited a moment and when no one spoke up with anymore questions he decided the meeting was over. "So everyone, Botan I'm sorry you're not going, pack your bags because in a few days you'll be off to England. Oh yes, one more thing, some old friends of yours have been recruited to help."

"Now Koenma," a smooth voice spoke from behind them. "You can hardly call us friends." The group turned around to see Shinobu Sensui and his partner Itsuki standing in the door way. "I don't even know half these people here," the former Spirit Detective added.

"What…but…he," Yusuke sputtered.

"I revived him for this mission." Koenma explained. "Itsuki, up till now had preserved his body and Shinobu has a rather strong will to live so it was actually rather easy. All he had to do was prove that he was reformed."

"I can see why dying gave you such power, Yusuke," Shinobu addressed him. "I'm completely back to the way I was before I split myself. No, better; I can see the truth clearly now, I can interpret the grey areas," he said with a smile.

"Yusuke, you need not worry. We have already determined that he is trustworthy. He and Itsuki will be going to Hogwarts with you, Shinobu as the new History of Magic teacher and Itsuki as his assistant." Yusuke found no point in arguing what had already been decided, so with out any complaints they headed out of Koenma's office to get ready for their next mission.

The next three days flew by with packing, planning and some boys making excuses to parents. Yusuke and Kuwabara's families took it easily enough, however Kurama's mother had one condition that needed to taken care of first.

"Alright Shuichi, you can go to this foreign school," obviously he had not told her about the magic part. "On one condition," she added. "You have to introduce me to this new girl of yours."

"What?" Kurama stared at her in shock; he knew he had never mentioned Jamie to her. "How did you know?"

"Call it mother's intuition," she smiled. "I was going to wait until you brought it up yourself but I'd prefer to meet her before you leave. Will she be going with you?"

"Yes," he nodded. "My friends and I have all been invited."

"So, tell me little bit about her," his mother asked although it was not really a question.

"Well," he thought for a moment. "She's not like other girls. She's a lot strong both mentally and physically, the kind of girl who's looks and possessions are not first on her mind. Um…innocent defiantly, and doesn't really like to talk about herself or focus on her own problems, which can be both a good thing and a bad thing." Kurama stopped to think for a moment, getting the feeling that he had missed something important. It suddenly hit him "Oh yes, she's a foreigner, from America but she understands Japanese," in truth Koenma had put the same incantation on the girls as he had put on the Reiki Tantei so that they would be able to understand Japanese. "And she and her friends are currently staying with Master Genkai."

After a few more minutes of conversation it was decided that Kurama would bring her over tomorrow, if she accepted which Kurama had no doubt that she would, for dinner so she could meet the family. So with that Kurama left to go ask Jamie to come with him tomorrow.

When he got to master Genkai's temple the sun had almost set, with only a few lingering rays remaining, casting oblong shadows over the ground. It only took him a few minutes to locate the girl; she was by herself in the garden making his job easier and sparing him the task of trying to catch her alone. He instantly came up behind her and wrapped his arms around her waist.

"Hey," he whispered in her ear. She did not jump; she hardly ever did, but instead looked up to meet his gaze and smiled.

"So, to what do I owe this pleasant visit," she asked. The statement itself was sophisticated her voice still held an innocent, child-like that tone that Kurama adored. He let her go and stepped back so she turnaround and face him.

"My mother, god knows how, figured out about you, and would like to meet you before we leave, or I'm not allowed to leave. To make it short you have been invited to dinner at my house tomorrow night, so I'm here to ask if you would like to come?" he presented her the invitation with a sweeping dramatic bow. She couldn't help but giggle at his show.

"I will on one condition," she answered him.

"What is it with you people and conditions," Kurama sighed with a smile on his face. "Alright, what is it?"

"I'd like to see your demon form," she answered simply. Kurama hesitated, that was not what he had expected. He'd still do it but he was he was definitely surprised.

"Alright, I still can't change at will yet so this might take some time," he responded. He himself was just as excited to introduce her to Youko. It is not that they were two different people, just two different mindsets, and he was dying to interact with her in Youko's mindset.

"Actually Kurama I've been looking to talk to you about that," a voice spoke from off to the side. They both looked to see Suzuka step out of the shadows.

"May I ask what you mean," Kurama addressed to the eccentric demon.

"Once again strait to the point," Suzuka sighed. "Alright, I've been fiddling around with the Potion of Past Life and I believe I have developed something you would be interested in." He held up a small vile filled with a bright red liquid. "This, I believe, should give you the ability to change at will," he explained as he handed the vile to the fox.

"Let me guess, you don't know about the side effects," Kurama stated.

"I'm pretty sure there won't be any," Suzuka defended. "But am I a hundred percent sure, no." Kurama looked from the vile, to Jamie, to Suzuka, and back to the vile.

"Well, we'll see," he said and he downed the liquid before he could think twice. After he had swallowed the entire thing he waited a few heart beats for something to happen. When nothing did he began to get confused.

"Focus on your Youko side," Suzuka instructed. Kurama did so and in the blink of an eye found himself donned with silver hair, gold eyes and a fox's ears and tail. He was also a lot taller than he had been a moment ago.

"Ah, it worked perfectly," Suzuka beamed as he clapped his hands together. "Koenma will be quite pleased."

Kurama, or rather Youko, turned his attention back to the blond demon at this statement. "What?" he asked simply. His voice sounded odd to his own ears, unaccustomed to the deep velvet sound that came from his throat.

"Koenma requested that I improve the Potion of Past Life for you, and who am I to turn down a request. Well, seeing as my presence is no longer needed, I think I'll go report the success. At that the demon let with a wave and a good luck, and disappeared in the direction he had appeared in. With the shock of this sudden event it took Youko a moment to realize that he was being stared at. He turned his gaze to be met by the wide wonder filled eyes of his lover.

"Well it looks like you'll get your wish after all," he laughed.

Um…" she squeaked in a hesitant voice.

"Yes?" he inquired. She reached a hand out towards him.

"Can I touch," she asked. He grabbed her outstretched hand and used it to pull her into his embrace.

"Of course," he answered. She squealed with excitement and started to explore everything, though not forgetting about modesty. His ears, his tail, his hair, she took delight in every little detail. She had always imagined what this man would look like in person but even in her dreams she had not come close, to either of his forms for that matter. "You're wonderful Kurama," she radiated with amazement. "Or should I call you Youko?" she asked apologetically.

"In this form, Youko," he answered. "From your reaction I take it you like Youko better," Youko commented as he wrapped his arms around his lover's shoulders. Her waist was hard to reach from this height. She vigorously shook her head, almost dislodging him.

"No, I love both your forms. It's just that this is so new…exotic." She had to take a moment to try and figure out how to word it so he would understand. "I mean, I've seen a human before, but I've never seen a Spirit Fox before. It's not that I love Kurama any less than Youko, there is just so much more about Youko I don't know." She looked up at him pleading eyes, begging him to understand. He did, but he wouldn't say it. She was adorable when she acted like this and he wanted to prolong it, so he just smiled.

"I don't know if anyone's ever told you this but you're very cute," he said. When she heard this she looked up at him as if he were crazy.

"Me, cute? I don't think so" she responded, but her head hung just slightly. He caught her chin and tilted her head up so that she was looking up at him.

"Anyone who has told you otherwise is wrong," he stated in an end of discussion tone as he gradually moved in closer towards her. "Kuwaii," he whispered in her ear before capturing her mouth in his own. She was amazed at how different the kiss was from Kurama's. It was much more aggressive and demanding, more like he was devouring her than kissing her, but the undertone was still he same. She vowed right then, as she was caught up in him, that she would never do anything to hurt him no matter what the cost.
