Disclaimer: If I owned either or both series, it just wouldn't be the same (which is good I think). I only own any OCs that may pop up (but I want to avoid this even except for baddies).

Author Note: Well, I've seen so many of these crossovers, but I wanted to attempt my own and give it some originality. I hope I can please everyone and make this a very well rounded fic. Read and review, please. And please note, for YYH it is a mix of anime and manga, but I have more experience with the former so I'll be going by that mainly. As for X-Men, I'm on pretty even ground between movie, comic and cartoons, but it's a mix of all with movieverse influences in age and who's where.

Once things had finally settled for the gang, things continued on in a calm manner, obviously enough. With Kuwabara in school and Kurama working, the two were the busiest of the group and even Hiei couldn't compare in his position, as there was little chaos in Makai as of late. Even if the three were busy though, they had the lightest load compared to their toushin friend and ally. It wasn't so bad that he still lived with Atsuko and that his and Keiko's relationship was progressing well which made things much brighter, but that didn't mean that working in her parent's ramen shop was entirely pleasant and trying to pick up his education again was a large burden. Things had gotten so bad, he ocassionally went to Kuwabara for help when Kurama couldn't make time. No, Yusuke was not an idiot and Kuwabara was not a genius in particular, but getting caught up after being so far behind needed work.

No rift had developed between the four either. While only one did not reside in Ningenkai, getting to the human world was an easy enough feat and Hiei spent whatever time he wished watching over his perhaps-not-so-unknowing sister and 'hanging out' with the other three. Koenma, now ruler of Reikai, had quite a full plate even but was content that the tantei could find peace. What sad revelations would reach him though.

Even with mutant activity on a rise, things were dying down with all the heat and action. Mutants went about their lives rather peacefully and most normal people ignored them and those who acted out were handled by just authorities or quietly 'made aware' by a small group of mutants. Xavier himself was rather pleased that things weren't getting bad at all, but too often now his brow would knit and a plainly concerned expression developed slowly over his features. He was telepathic, not psychic afterall and no master of gut instincts the way Logan was, but he knew a bad feeling when he felt one approaching. He wouldn't bother his students or the X-Men over the issue now, but he continuously pleaded to the powers that be that things would not get out of hand.

'How much will the world endure before everything collapses under itself?' Lids closed heavily and a frown permeated about his lips. Even the figure coming toward his office had caught him off guard with a knock to his door. Such a shame that the matter had him that unaware. He knew then it was no longer so simple. He fixed his expression and looked up slowly, calming himself. "Yes?"

Rogue peeked through his door shyly and smiled tenderly. "Professor, dinner is ready." His smile grew and he nodded quietly. Could she have been aware that he was caught up? She was so bashful about disturbing him, maybe it was that obvious. "I'll be there right away." A fatherly smile broached his lips and earned him an exuberant smile as she left quietly, though her cheer was still felt about the room. The cheer only a young innocent could possess. Perhaps he had overlooked some matters. But now, the more important matter of dinner called out to him and he wheeled himself to the door and out the room, wondering what other realizations would strike him upon reaching his destination.

"Damnit, none of this makes sense. What the hell?" Yusuke gave a frustrated glance at the books and papers lying about him and flicked his pencil about them as he leaned back, a hand resting on the floor behind him as support. Kuwabara gave a chuckle and Kurama smiled amused. "Oi, Urameshi, this is supposed to be a time to have fun, not study. Ahou!"(1)

Kuwabara laughed again as he poured himself a drink before promptyly spilling on his lap, a hand meeting the back of his head. "You wanna fight?"

"Haa? You challenging me!?" Kuwabara jumped up quickly with cup and sake still in hand as they glared each other down. Kurama looked on bemused, though his expression showed otherwise. He was however thankful for the coming presence that soon loomed over the two boys. "Hey, knock it off punks. Calm down and don't make a mess of the place." Shizuru gave them both a stern glare on a surprisingly - and may frighteningly? - blank expression. Immediately, Kuwabara backed down like a scared puppy and Yusuke gave a nervous smile and sweat as he backed away. True enough, he would defeat Shizuru going all out, but she was known for laying a beat down onto her opponents. He was sure she was scarier than Keiko even.

Yukina giggled quietly as she approached them from her seat on the couch, diverting her attention from the wild show on the television. "Kazuma-kun, it is a time to have fun you said. Lets all enjoy it properly." She clasped her hands together and gave a cute smile, leaving Kuwabara to go into a full on mode of swooning and agreeing, eagerly waiting on her hand and foot. Kurama turned an exasperated glance to Shizuru who met his gaze with a 'I give up' expression. No hope in her eyes.

"Geez. She gets it curly brows, why don't you go make her a buffet now too?" (2)

Yusuke sneered at Kuwabara with his poking remark before smirking as Kuwabara gave him another grimace. "Is this the thanks I get for helping you study!?" Ouch. Yusuke flinched and pursed his lips. That was a low blow. It wasn't his fault that he had other things that needed tending to while Kuwabara became mister popular on campus. He basically would have had a fan club even just about. Kurama explained what he had seen and how amused he was. Yusuke was shocked before wavering between impressed and stressed.

"Hn. He probably wouldn't be able to pull it off anyway." Every head turned quickly and some expression of shock escaped everyone's lips as their attention turned to the window by the sliding door. Hiei sat perched on the sill with his gaze directed heatedly at the group before turning to look out the window. "Hiei! You can't go scaring people like that, you're creepy enough as it is." Kuwabara waved a fist at him and let the jab to his pride slide, turning back to Yukina. "Just ignore him, Yukina-chan! I would make the largest buffet ever if you requested." She laughed softly in return and the two went about a surprisingly fluffy conversation with a seething fire demon in the corner and two unsettled youkai trying to keep their distance but stay on guard.

"You guys are weird." Shizuru put out her cigarette before going to the door and opening it slowly as Keiko stood with her mouth parted slightly and hand poised to knock. Botan leaned in from behind her and smiled warily. "That was kind of fast Shizuru."

"Yeah, yeah. Just come in already." The two girls entered ready to the join the others with the blue-haired reaper obviously the more giddy of the two.

Tiger eyes watched the scene unfold with a hint of envy sparked in their depths, slowly turning the opposite direction to catch sight of a newcomer. A sneer and a moan stated the disgust toward the new presence. "Hmph, don't act so high and mighty. It's about time we got started, they will get impatient afterall." A handsome man gave a narrowed, disdainful glance at the cat-eyed woman before looking across the way to the building which their targets resided.

"Whatever. You can leave now!" Her hiss was as threatening as the animal she most resembled. His face hadn't changed as he turned swiftly as seemed to disappear in a dimension distorting flash, one movement opening the rift that closed within seconds.

A purring laughter echoed in her throat, not breaching her lips but evident enough. "I'm going to give you the pleasure of being introduced to my first prey."

Keen as she was, Jean had mixed feelings about the emotions she tried to pick up from Xavier. She felt that things were off with him and hoped that meant she could pick up something, but he continued to play the master of caution and as usual, unless carefully reading his expression Jean had gotten no where. But she couldn't make a big deal of it in front of everyone, lest they find themselves in a sticky spot. She plastered on a smile she guessed could have been as plastic as his own and went about eating her dinner, glancing about the table before a steady but small smile drifted to her lips. Ororo had a particularly far off gaze tonight, and that left Jean wodnering. At least someone was far from in any sort of a foul mood.

"What's up Red? Daydremaing about me?" Jean nearly blanched at the remark and cast Scott a wary look before turning to Logan. He was so pushy at times. For the most part, she could tell his comments were to push Scott's buttons, but she was glad for the attention. "No, Logan. I was distracted by a passing thought, but nice try anyway." Rogue giggled softly and Ororo turned an amused but cautious look to the apparent 'love' triangle. Although Jean and Scott's love was strong, did it overshadow the dark feelings Logan and Scott had for each other? True enough they could be good comrades, but that did not mean they were buddy-buddy.

The windrider shook her head and smiled at a few others at the table before excusing herself. Jean promptly followed suit and it didn't get by Ororo, though she acted rather indifferent. She headed for the kitchen swiftly but took her time inside and walked out the doors to the living room with purpose. Jean caught up to her in no time and linked her arm when beside her taller friend. "So, time for the evening gossip. What is on your mind Ororo?"

What emotions in her eyes spoke the little trivial things about what the white haired beauty had in mind and the pretty red-head soon began to anticipate and dread their talk.

She lay on her back with glorious, deep red hair laid out about her and hands on her stomach. Ororo had taken to watering her plants before she finally spoke up. "To be honest Jean, I'm pretty jealous. Even if it is to just to irk Scott, you do have the affections of two men directed at you. Though it seems a bit troublesome." Jean responded with a solemn shake of the head and comical expression as she sighed heavily. Ororo laughed shortly and continued on. "I've become bored honestly. I don't necessarily want a mission, but some sort of action would be nice."

Jean jumped up quickly, leaning on her side with wide, starry eyes. "Are we talking romantic action?" A white brow arched and cryptic smile snuck up on full lips. "I didn't say that. Although it brings up a point that I'm worried about. The professor... was he-?"

"Not at dinner tonight? Hm, I couldn't catch a thing, but he was not himself. He wasn't here, but he was aware enough to make sure nobody could read anything too deep if at all." Dazzling, green orbs turning to the plush, regal hued carpeting adorning the attic's flooring. "I wonder what has him so thoughtful. I'm worried Jean. It's so calm but he's so worried. Maybe all this peace is planned. It's just a ploy to get us off our guard for some enemy to sneak up and take us out."

While voicing herself, Storm had allowed her gaze to remain pointed at her plants before finally looking up to Jean and feeling rather surprised. Her expression recovered quick before her lips burst into a mocking grin. "Ororo, that was rather dark don't you think?" Jean was half-laughing while trying to keep a serious expression. Where had that imagination been sleeping and why for so long? No longer able to hold back, she laughed and clutched her side at her friend's reaction before sitting on the edge of her large bed. "My apologies Jean. That was a little out there. But I think we need to stay on guard, or else we're going to get it." She pointed a finger at Jean in a teacher-scolding-student manner and set a grim frown on her lips. Jean looked abashed before breaking out into a grin and both laughed.

"But seriously... maybe we should be-"

'Jean, Ororo, please come to my office immediately.' Charles's voice rang out in both of their heads in a stern, upset manner and they cast each other scared glances. "Oh."

-

Her energy flared quickly and a thick, gas-like substance of varying colors now encompassed her fist. "Well it's not like I'll get in trouble for damages, so might as well make an impressionable entrance!"

It was so minute, but it was there. And entirely unfamiliar to all of those with any ki senses at all. Shizuru's eyes narrowed coolly and Kurama turned a cold glare to the door while Yusuke and Kuwabara looked as though their hairs were on end. Hiei however seemed as though he hadn't a care in the world and hadn't budged.

The rising energy and shock on each one's faces spoke loud enough and even the shielding of defenseless that initiated within time did not mean they would be able to properly approach their situation. The door and part of the wall came bursting in, wood chips and shards flying about in a chaotic manner. Screams echoed in the now too open space and Yusuke and Kuwabara lifted themselves from the girls they had put themselves to protecting. While Keiko's expression read startled and tormented, Yukina's face was one that would be better suited to her brother, though showing a mild amount of bewilderment. Kurama turned from Shizuru and Botan to look to the hole and frowned. A rather youkai-looking female stood where the door should have been with a maniacal though haughty expression on her face. "Hah! You guys are such simpletons, don't waste your time fighting back!"

More energy gathered around her fist and immediately took on a gaseous state as she flew to the middle of the room before jumping back. A line of silver crossed any path she would have chosen and she sent a scowl at Hiei. "Watch it kid, or I'll smash your face in!" Her cockiness was entirely too funny and her attempt at intimidation died down with a glint from his katana.

A smirk and pleased 'hmph' were the only response required of him. The others were not going to butt in.

-

"Professor?" Jean entered quickly with Ororo hot on her heels and both giving him worried looks. "Please you two, sit."

They took seats before him after closing the door and seemed to calm down slightly. "No need to be alarmed, but it seems a situation has come up and I want you two to see to it."

They both nodded and Jean felt something tug at her mind. Was Ororo becoming psychic? Or maybe something in the air had alerted her that trouble was brewing.

"I've had an odd feeling for some time, but just now my senses and an outside force have enlightened me to the cause of this. There's a bit of chaos that has sprung up and needs investigating, but this needs to remain between you two for now." Things shouldn't escalate to become too much for them. The energy signature didn't seem that bad of a threat for both of them together. Jean's telephatic abilities had always been amazing and for some time now, Ororo was quite a force to be reckoned with. If things got bad though, he wouldn't hesitate to send Logan along for the ride.

"Professor, where are we going though?" Ororo clasped her hands and leaned in curiously.

"You may need to pack a bit, but nothing heavy. And you may be fine Ororo, but I suggest brushing up on your Japanese Jean, or find an alternative route." They both seemed to nod slowly for a second before narrowing their eyes and leaning in, their surprise not at all hidden.

"JAPAN!?"

So yeah. I don't know what would be best to say, but I do promise the story will get better. I mean action, writing, character development and everything. And things will take place in both countries. Yay. If anything seems too off or out of context, please alert me and I am open to constructive criticism, though no bashing or flaming of any kind. Also, I have pairings and stuff developing in my mind, but anybody have any opinions? I do realize a few people may have been out of character too, but I'll work on it.

1) 'Ahou' is Osakaben for 'idiot'. A real insult for someone from Tokyo to be called that and vice versa for 'baka' and an Osakan.

2) One Piece joke. Yusuke is referring to how Sanji dotes on Nami (women in general) and part of it is the cook allusion. Kuwabara does remind me of Sanji when it comes to Yukina though, which is why I threw it in there.
