Disclaimer: I do not own Harry Potter or Yu Yu Hakusho and their characters. However, Kuro and Rena are of my own creations although they are minor characters that don't really matter or serve much of a purpose. Sorry for forgetting to include the disclaimer in my previous chapters.

Author's Notes: I stink at fight scenes. I really do. I can't write them well so this chapter might be a little awkward. I apologize for that. I am hoping to god I won't doom myself into writing another one in this fanfic.

And I apologize for the wait. This chapter is considerably longer than the last three because I intend to write more and hopefully include Draco once again.

By the way, I don't really care what year you think this is. Because I had completely forgotten about it myself. Sooo..um.. let's just say it's 6th year.

Mission Hogwarts – Chapter Four

Written by Clow Angel

- - - - -

Yusuke with Puu sitting on his head looked around at his surroundings with interest and awe while Harry and Ron followed the three Japanese natives at a distance watching as they spoke in what they assumed to be rapid Japanese. Although they couldn't understand a word, they knew Yusuke was impressed. The dark-haired teen was pointing at this and that, gaping, and making whistles of appreciation while Kurama looked amused, shaking his head, a smile dancing on his rosy lips. Hiei's expression remained unchanged from the scowl he wore. Still, even if they didn't understand a word, they felt a small amount of pride swell up in their chests at a foreigner's obvious amazement at Hogwarts Castle.

"This place is pretty cool! Ghosts, moving pictures, dungeons, and batty teachers, you've got the weirdest shit in here. What more can you ask for?" Yusuke laughed loudly.

Kurama smiled, leading his friend to the Great Hall. "Yusuke, don't forget I'm not here to sightsee, I'm here for a mission."

"Yeah, yeah," Yusuke said, rolling his eyes and waving his hand in a dismissive gesture. "I get ya, but hey, relax once in a while."

"Do I look anything but?" asked Kurama, a bit miffed.

Yusuke actually took a good look at the redhead, scrutinizing his expression. "Well, no, but you do look a little pissed off."

"If I look any bit angry, it's because you interrupted my sleep," said Kurama, his voice taking on a stiff tone.

Yusuke jumped a little. "Sorry! I forgot the time difference. It won't happen again."

"I doubt it."

"Hey!" retorted Yusuke, feigning hurt in his voice. "Okay, so it might happen again."

Kurama sighed. Finally reaching the Great Hall, he pushed the large doors open with little effort and gracefully led his teammate to the Gryffindor Table and taking a seat. Yusuke followed the kitsune's example and plopped down on a spot across from him. He stared up at the bewitched ceiling and whistled again.

"That's a nice ceiling! I want that for my apartment," Yusuke said in English this time.

Harry and Ron exchanged a look and shrugged. "Your school didn't have anything like that?" Ron asked curiously.

Yusuke finally noticed the pair. "Oh! Sorry, didn't notice you, but nah, we didn't have stuff like this. Genkai preferred to keep everything simple."

Yusuke soon noticed food had appeared on the table. "Uh, we just magically get food here? Sure is different," he commented before digging in.

"How is it so different?" Harry found himself asking.

Yusuke couldn't answer; his mouth full of sausage and toast. So instead, he reached across the table and gestured for Kurama to answer for him.

"Well, we usually do everything by hand. We were taught not to rely on magic for everything. That way, we won't get lazy and lose the appreciation for the simple things in life and the satisfaction you get out of hard work."

"How is that any different than muggles?" said Ron, then stuffing a piece of toast in his mouth and chewing thoughtfully.

"It isn't really. Still, it does not mean we don't use magic as well."

Harry sort of understood, but not really. After all, he was forced to do all the house chores including gardening, cooking, mopping, and laundry so he really appreciated magic.

"So, when can we fight? I'm really itching for a fight."

Hiei who had remained relatively silent finally rolled his eyes and threw a piece of toast at the dark-haired teen. "Shut up about the fight. We're eating and you still need to see the old man."

"Oh." He sounded disappointed. He had really been looking forward to a thrilling match. It didn't even matter if he got the shit beat out of him. He hadn't had much excitement since the pair left Japan for this dumb mission.

Kurama somehow felt sorry for the hanyou. "It doesn't mean we won't fight you. We'll just have to have our match after you meet the Headmaster."

"Okay…" he said in a somewhat subdued voice, still evidently disappointed.

Ron and Harry didn't even want to know why someone would want to so desperately fight someone with the risk of horrible injuries. After witnessing a few of Kurama and Hiei's light spars, they weren't sure they wanted to see a serious match.

Hermione chose to walk in a few minutes later, taking a seat by Harry. "Good morning," she chirped.

"… And who are you?" she asked once she noticed a stranger at the table.

"Oh hey, I'm Yusuke. Nice ta meet ya!" he greeted with a confident smile.

"Oh! So you're Yusuke! I've heard much about you from Botan. Nice to finally meet you," Hermione greeted him excitedly. Then confusion clouded her eyes, "but why are you here?"

"I got bored so I dropped in to visit my two good friends there." He pointed to Kurama and Hiei who were quietly talking to each other about one thing or another. "But they're being mean and won't fight me."

Hermione was speechless. She had heard from Botan the boy liked to fight but had no idea he would fly across half the globe just for a fight.

"You don't need to look at me like that," Yusuke waved a hand at her. "I just happen to like challenges and working up a good sweat. Nothing beats a challenging fight."

"I can't really understand, but I'm sure you have your reasons," said Hermione.

"I don't really have a reason though. I just like fighting. Plus, keeping in shape's important."

"Oh," said Hermione blankly.

"Yusuke!" It was Botan and she looked extremely happy to see him. She ran over and tackle hugged him right off the bench and onto the floor. "It's been so long! How are you?"

"Just—fine…." Yusuke wheezed from under the exuberant shinigami. Puu, who had been jostled from his perch, landed on the table instead and stole a few pieces of bacon.

"When'd you get here?" she asked, still clinging onto him.

"Not long ago," he said, sitting up and gently pushing the girl off of him.

She got up and took a seat and her food appeared right away. "Oh? You're not eating?"

"I already finished." He quickly reseated himself and proceeded to annoy Hiei by shooting small orbs of reiki at the hiyoukai which bounced off and dispersed into bright blue sparks. Hiei's eyebrow started to twitch but he didn't say anything. Instead, he took a long swig of pumpkin juice.

"Aww, come on, react already," whined Yusuke.

"You keep this up and I won't fight you at all."

Yusuke took the threat to heart and immediately stopped and turned to Kurama. Before he could do a thing, Kurama looked up at him.

"Try something and you'll wish you were dead, Yusuke-kun" Kurama said lightly, almost cheerfully but his eyes had a devious gleam in them.

Yusuke huffed and muttered, "Damn you and your creepy plants…" He laid his head on the wooden surface of the table and groaned. "You all suck."

Botan giggled and slapped Yusuke playfully on the back. "Don't be like that!" She then proceeded to play and wrestle around with Puu.

Hiei and Kurama soon finished breakfast and led Yusuke with a comfortably seated Puu on his head to the stone gargoyle statue, gave it the password 'Milky Way' and it promptly leapt out of the way revealing a set of spiral staircases.

Yusuke scratched his head and muttered, "Weird" but followed his friends up the stone steps anyway.

Hiei knocked on the door once and an old voice said, "Come in, come in."

The short fire demon yanked the door open with more force than necessary, stepped inside along with Kurama leaving Yusuke to follow.

"Wow, nice office!" His brown eyes traveled across the walls and various magical knickknacks finally landing on the firebird Fawkes. "Holy—, it's a phoenix! Never seen one up close before." Puu leapt away from the intimidating looking bird and flew over to Kurama who immediately took him into his arms.

Dumbledore waited patiently and watched the teenager browse his room and finally walking up to Fawkes' perch and examining the bird. His pet looked back at the young man nervously and his bright colorful crest of feathers twitched, irritated at having someone he didn't know lean so close into his face. When Yusuke spoke again, the volume of his voice booming into his bird-sensitive ears, Fawkes looked affronted and took flight, beating Yusuke over the head with his large wings then slapping him with his hot tail feathers as he flew past him, and finally landing on Dumbledore's shoulder.

Yusuke jumped back the moment the burning tail feathers hit him in the face. He put a hand on his face and rubbed the burn gently trying to sooth it. "Ow…"

Dumbledore chuckled with mirth, light blue eyes twinkling. He stroked Fawke's beautiful head. "Sorry about that. Fawkes doesn't warm up to strangers easily. Madam Pomphrey can heal that burn after you leave."

"Oh, no thanks. It'll heal." The burn was fading. His youkai blood was working already.

"But anyway, it is a pleasure to meet you, Mr. Urameshi. Did you come bearing any news of your comrades' mission?"

"Not really. We haven't received much information other than the fact that this Voldywort—" his friends smirked and Dumbledore raised a silvery white brow at Yusuke's butchering of the dark wizard's name. "—guy is bad news. He might be gathering demon followers or something. Nothing Kurama and Hiei can't handle alone." Yusuke took a seat on a comfy armchair as he continued. "What are their names, — Rena and Kuro I think already told you that though."

Dumbledore nodded. He had indeed heard from the two grim reapers of the news. He had been most startled. Wizards were not trained to fight such dark creatures. Many still believed them to be mere myths and legends but he knew better. He feared for the school's safety but when Botan giggled and waved away his worries with her cheerful, "Well, we have nothing to worry about then! If they find out Kurama and Hiei are here, they'll run in the other direction!" he relaxed a little at the foreigner's obvious calmness about the news.

"We can cope with the help of your two dear friends," the old bearded man nodded at Kurama and Hiei. "I hear they're especially trained to fight them."

"Uh, yeah, something like that." Yusuke said with an uneasy laugh. Koenma had probably conveniently failed to mention they were demons.

Dumbledore knew without a doubt the newcomers probably had a few secrets. "You need not reveal your secrets. I have no need to know unless the information may prove harmful to my students and staff."

Yusuke looked at Kurama and Hiei, eyes holding on Hiei's scowling expression with a small bit of worry before looking once again at Kurama's serenely calm expression. He grinned at Dumbledore. "Nah, your students and teachers are safer than they ever were before if you've got these two—" he jabbed a thumb in his friends' direction. "with you, and Hiei won't blow anything up if Kurama's around."

"Well, thank you for coming to visit. I enjoyed our talk." He smiled, resting his bearded chin on his folded hands. "Please do come again."

"Yeah, no problem." He said distractedly, then leapt off his seat energetically and looked over in his friends' direction and waited for them to finish their conversation. "C'mon! You promised!"

Kurama sighed tiredly. Hiei glanced at the redhead in concern for a split second, finding that there was nothing wrong with him before grinning at Yusuke, a single fang poking out. "Fine. Don't cry when you lose."

"Ha! You'll eat your words Hiei!" Yusuke wrenched the door open and flew down the spiral staircase whooping and laughing in his excitement. He couldn't wait to get outside.

Hiei soon disappeared after him leaving Kurama alone in the office with Dumbledore. Fawkes who seemed to be able to tell something was going on, screeched and took flight out the door following Hiei.

Kurama chuckled. "I apologize for Yusuke's behavior. He has always been the most —" he searched his mind for a word, "— rash out of our group of friends."

"What, may I ask, is he so excited about?" Dumbledore's eyes twinkled with interest.

Kurama couldn't help but smile sheepishly. "Yusuke wanted to fight me and Hiei. Not seriously, but as exercise and to refine his skills. We often did this back at home."

"I see I see. Then do not let me keep you."

Kurama sketched a quick bow and quickly walked out, not forgetting to shut the door softly behind him. He then bolted down the stone steps to find his teammates hoping against hope that they haven't caused a scene yet. The gods were on his side today. Dark clouds were gathering overhead and the loud rumbles of thunder were drawing near.

- - - - -

Yusuke groaned. He had decided to stay the night and Dumbledore had welcomed him with offers of lemon drops which Yusuke gladly took a few. Once he had gotten outside, it had started pouring.

Hiei being a fire demon quickly took refuge inside the castle, refusing to spar in such weather. Hiei had fought in rain before but he'd rather not, when it wasn't life or death situations. He preferred to be perfectly dry. He left a frustrated and cursing Yusuke behind.

So, he ended up staying the night in the Gryffindor Common Room, not minding his sleeping arrangement being the couch. It was actually a pretty comfy couch. But now he was bored and he couldn't bother Kurama with chatting. The redhead was studying. "As if he actually needs to," Yusuke mumbled to himself. He was sprawled on the couch with his arms behind his head.

Hermione chose that moment to drop into an armchair close by startling Yusuke out of his boredom. "So Yusuke, what do you think of Hogwarts?"

"It's pretty cool. This room is also pretty nice, but the entire castle is too big. The vanishing steps and moving staircases are pretty neat though."

Hermione laughed lightly. "Tell me a little about yourself." Hermione smiled and sank back into her seat taking a more comfortable position. "About Hiei and Kurama too," she added. "They don't really talk much about themselves. Anything I know is from what Botan and Yukina tells me."

"Sure." The delinquent shrugged. He didn't have anything else to do and he knew not to say anything that might hinder his friends' mission. "What do you wanna know?"

"Well, um, what do you think of Kurama and Hiei?"

"Hiei is short with an equally short temper. He's pretty cool and fun to tease." Yusuke grinned. "But he also tends to set me on fire if I tease him too much. Not that I care. He's got a pretty hot temper. He wouldn't think twice about throwing me into a wall or like before, punching me into a bolder. But that's what I like about him I guess; his not thinking twice about hurting his opponent attitude."

"I see why he ended up in Slytherin," Hermione commented.

"Really? What's Slytherin like?"

"Slytherin is considered to be the most rotten House in Hogwarts. They're full of greedy, self-centered people. Still, there are some alright people in Slytherin House too. Not all of them are horrible."

"Well, Hiei does really only care about himself most of the time, but he's not too bad. He's saved my ass more than once, although grudgingly. Still, he's a good friend to have. I definitely don't want him as my enemy. He'd skewer me with his sword then roast me."

"What about Kurama? What do you think about him?" Hermione asked. "He's in my House, but he doesn't talk about himself at all."

"Kurama?" Yusuke frowned, eyebrows drawing together. "You know, I don't really know much about him either but he's a nice guy. Real smart. He's also saved my ass quite a bit. But I can never tell what he's thinking, ya know. He always has that calm and nice expression." He couldn't really tell the curious girl much more without blowing their covers.

Hermione nodded. "I've noticed that actually."

"When he's angry, you'll know it too. Unlike Hiei who literally growls and snaps, Kurama is eerily calm and expressionless which lets him make very quick calculations in pinches. It's really fucking scary. Whoever's on the receiving end of his anger is in deep shit. That's why I don't mess with him. Hell, Hiei doesn't mess with him. That should tell you something."

"So it's true then? What Botan said," Hermione said almost absently.

"What'd she say?"

"Oh, um, she told me Hiei had said he chose being friends with Kurama than enemies because he is a strong person or something along those lines."

"Wow, she remembered?" Yusuke laughed. "Yeah, he said that. It was when we all first met. Of course, I didn't believe Hiei at all then. No matter how you look at him, Kurama looks like a pretty boy who couldn't hurt a fly. And the next thing I know, Kurama pulls out a rose! A rose!" He started laughing remembering the fight with Genbu.

Hermione didn't get what was so funny. "So, Botan wasn't lying? I swore she was pulling my leg. I've never heard Hiei compliment or say anything nice about anyone. Ever."

"It's rare for Hiei to compliment anyone. Hell, he's never said a single nice thing to me. He'll sometimes say things like –you're not too bad for an idiot- but there's always an insult too! It pisses me off." Yusuke huffed and sat up suddenly as he said that. He let his body fall into the couch again a second later.

Hermione couldn't help but giggle. It sounded like something Hiei would say.

Yusuke was suddenly serious. It was a strange expression and seemed out of place on the cheerful and rambunctious teenager. "But however and whatever they're like, they've come to my rescue when I was in a pinch and I'm thankful for that, ya know? You don't get many friends who'd face danger with you. God knows I've put them through lots of shit. Still, they're here with me laughing with or at me. They're great people! Wouldn't want them any other way."

"Now, tell me about yourself. You didn't really come here just for a match, did you?"

"Me? I'm just a happy-go-lucky guy who loves fighting. I live for it, so, hate to tell ya, but I did come for a fight and nothing else. Of course, I wanted to see how Hiei and Kurama were doing over here in a foreign country too. I was afraid Hiei might've blown up the castle." He laughed heartily when Hermione stared at him in bewilderment uncertain if he was joking or not about Hiei blowing up the castle.

- - - - -

The next day, Yusuke finally got his wish. The rain had gone away and the skies were clear and blue, not a single cloud in sight. The group had found a nice secluded clearing behind the castle hidden by a large amount of tall trees that blocked the area from view. Harry and Co. eagerly followed to watch this once in a lifetime match. Yusuke insisted his friends dress up in battle outfits for the occasion and thus Hiei found himself in his regular black getup and Kurama donned one of his many Chinese-style battle robes. For once, he wore black to match with Hiei. Yusuke had wanted to fight both of them, a two on one match.

Hermione was especially looking forward to the match. She had missed the spars between Hiei and Kurama so this would be her first time witnessing their powers and abilities.

The three faced off; Yusuke on one end of the clearing and the best friends at the other end. Harry, Ron, and Hermione were sitting comfortably on the grass out of the way of the battleground. The three Reikai Tantei bowed and were off. Prior to them all getting there, they had agreed not to use super human strength and only use moves that appeared to be magic so no questions would be asked. Yusuke agreed wholeheartedly claiming it would be more of a challenge.

Hiei was impossible to follow with their eyes. He flashed, reappeared, and then flickered out of view again only to appear elsewhere. He threw fireball after fireball at Yusuke who half the time got hit and half the time dodged. Hermione couldn't believe her eyes. She had thought Ron was just making things up again but now, she believed every single word the Weasley had said about the shorter boy.

Yusuke was amazing. He was almost as fast as Hiei. He held his hand like a gun and bright blue balls of energy shot out of it, racing towards his friends only to miss as they dodged. Instead, his ki slammed into the surrounding area and caused a total mess of flying grass, dirt, shrubs, and rocks. Occasionally he'd pull his fist back and slam them forward and several dozen balls of energy would shoot forward. His dexterity and ability to take hits were astounding to the three friends watching. He also managed to go against two people at once with little difficulty.

Kurama's movements were fluid, graceful and deadly all at once. He performed acrobatic flips and twirls several feet in the air and landed with such ease while dodging, parrying, and performing attacks, Hermione was sure dancers and gymnasts would be green with envy. He used the environment to his advantage, the fauna and green growth surrounding them moving and attacking as he wished them to. His strength was also amazing for such a slim-looking man. He had split a small boulder in half with his Rose Whip.

What was even more amazing was Hiei and Kurama's teamwork. The two switched from offensive to defensive fluidly almost as if they instinctively knew what the other wanted because they had not spoken a word since the match had started. With the slightest of eye contact, they planned the next move and executed it with deadly precision.

Normally, Harry and his friends would agree fighting is a bloody and barbaric act, but this battle was proving them wrong in so many ways. He had never seen a more dangerously beautiful dance in his life. The level of teamwork was unbelievable. The way the attacks were executed could be deemed a form of art. The entire time the Golden Trio were watching, they watched with baited breaths, gasping and holding their breaths when an attack came close to hitting someone or did hit. They breathed out in relief when an attack missed. Occasionally, a comment of "That was bloody amazing!" or something similar would escape from Ron's gaping mouth when he witnessed a move that was executed with such complexity but made to look so simple.

An hour later, the Reikai Tantei, sweating and smiling, stopped, bowed to each other and walked over to Harry and his friends.

Yusuke's grin almost split his face in two. "So? Whadda ya think, eh? Cool wasn't it?" He boasted cheerfully, thoroughly satisfied. He had finally gotten to work out. If only they could've gone full out, he would've been happier but he didn't want to risk doing anything too damaging to the surrounding area and drawing a crowd.

"Well, I haven't done that in a while. It isn't often I fight you, Yusuke. I thoroughly enjoyed it," Kurama smiled brightly, sweeping a wayward crimson lock out of his face. He needed a shower.

Hiei stood next to Kurama examining his sword making sure nothing had happened to it. Satisfied that it was still in excellent condition, he sheathed it. "Do not expect us to go easy on you next time, Yusuke, but you weren't too bad this time."

"Hey! I beat you once!" Yusuke protested, referring to when he was on the mission to capture Hiei for stealing the three artifacts.

"Once, and with Kurama's help."

Yusuke sputtered indignantly. "Well, well—"

Hiei smirked.

"Fine!" Yusuke finally grumbled. "But I'll kick your ass next time!"

Hiei didn't see the need to deign that with a response so instead inspected the kitsune for injuries leaving a fuming and cursing Yusuke behind for Harry and Co. to deal with.

"…" Harry, Hermione, and Ron exchanged looks. "You were going easy on each other?"

Kurama shook his head in mirth and chuckled. "It was just sparring; we have to go easy on each other. However, Hiei and Yusuke's spars usually do end up a little bloody."

"Ah, Hiei," greeted Kurama with a warm smile. "Before you ask, I'm fine. It's nothing I can't take care of."

Yusuke patted Kurama's back roughly. "Ma ma, he'll be fine! He isn't Kurama for nothin' you know."

Hiei narrowed his eyes and turned away.

"Thank you Yusuke." Kurama chuckled at the energetic teen.

Yusuke decided to stay another night. He rather liked the castle and enjoyed being with his friends again. An entire year or more without his team mates' presence was going to drive him nuts so he preferred to stay for a few more days.

Draco Malfoy was troubled, pacing his room with his arms folded against his chest. He was tempted to set the letter he had just received aflame. Perhaps he really did need to go see the old fart.

Crabbe and Goyle exchanged worried glances, not liking their leader and best friend in such a state of distress.

Ignoring his room mates' worrying, Draco continued to pace. Back and forth, back and forth. 'Curse you Lucius,' he mentally spat. If it wasn't for his father, he wouldn't be in this mess.

"Crabbe, Goyle, I need to see Dumbledore. Wait for me." He took the letter from his desk and placed it safely in his pocket wanting only to tear it into shreds.

Showing that they weren't really all that stupid for once, Crabbe asked, "Is this about your dad?"

Draco stilled, his hand a mere inch from touching the handle on his door. He bowed his head slightly, brows furrowed in frustration. "Yes, this is about Lucius."

"We'll wait for you Draco. We'll always wait for you," Goyle reassured. Well, as much as he can sound reassuring with his pathetic stupid voice, but he tried. It's the thought that counts right?

The blonde couldn't help but smile. Sure Slytherins were known to be backstabbing gits, but his lackeys really were true friends. "Thanks. I appreciate it." He escaped out the door in search of the Headmaster.

- - - - -

Okay, I lied. ; It didn't include more of Draco but he did appear! And he seems more important now. I swear he'll appear more in the next chapter.

And since I decided to make Yusuke stick around for a little more, not much more, but a little more, poor Draco's life is going to turn upside down and inside out. Don't you just love Yusuke's way of making friends?

Anyway, onto review replies!

Neko1kitty – Yeah, I was planning on making this into a Yu Yu Hakusho AND Harry Potter Crossover after all. It won't just be all about Harry. I'm trying to make things come together slowly because I'm still brainstorming. I don't want to rush everything but at the same time, I don't want to make everything happen SO slowly that well, we'll all be dead before the story ends. As for the big bad guy, I'm not sure I want to make it up. We'll see though. I have some ideas brewing. Thanks for your input!

Thunderstorm101 – Hahaha! How cute! I like the idea! I'll try doing that! Thank you for the ingenious idea! Why didn't I ever think of that?

Mizuki hikari – Heh. Yeah, Draco's in trouble and he definitely needs help, but will Kurama really be the one to help him first? Hmmm… We'll have to wait and see.
