There aren't many, but it's enough for my first real crossover. Also, please note that this is purely for fun and to celebrate the Halloween holiday, so if some of the characters' personalities are OOC, remember, it's all for the humor.

If I forgot someone, let me know. It's because I can't remember what the hell I just wrote XD.

"So, this is where it's supposed to be?" a voice wondered, thick with a country accent and cheerful, despite the haunting glow of the full moon.

"It's kind of... dreary," a girl's voice whispered as the girl herself shifted closer to the boy next to her.

The redhead at her side rolled his eyes and waved a hand, "It's nothing to worry about, we're a lot scarier than anything you could find here."

"I'm not scared!" Rio shouted, then clasped her hands over her mouth. She looked to Kanone and then decided perhaps Kousuke was right-- the Blade Child was fairly dangerous.

"Can we just get going?" Ayumu yawned, looking to his side where Hiyono had decided to stay glued. It was her fault he was here at all, and Rio's fault they were out in the first place. The chibi girl had decided that she wanted to go to a real haunted house, and had enlisted the knowledgeable Kanone to find such a place. Hiyono, at the time, thought it sounded like loads of fun, but drug Ayumu to protect her from anything they might encounter. Kousuke had come to snicker at Rio's cowardice and Kanone had persuaded Eyes to join them.

So, the seven of them were standing outside a large, abandoned mansion in the middle of nowhere. Halloween night was the perfect time for hauntings, and this was the perfect place. The rickety gate that hung, rusted and limp on its hinges, swung open with the slightest nudge, and drew out a horrible creaking sound that sent shivers down Rio's spine.

The group ventured forward through the overgrown brush that littered the walkway towards the darkened house. Something stirred next to Hiyono's feet as she stepped over a tree root and she promptly clung to Ayumu's arm. "There's something there," she hissed.

"It's probably a wild animal," the brunette muttered, not at all concerned.

"Narumi-san, you're not being any fun," Hiyono complained, "Don't you want to be scared? It's Halloween!"

"Being scared isn't really my thing," he admitted, shrugging, "but you have fun, alright?"

"Come on," Kousuke said, drawing the group's attention, "I'm sick of standing out here in the cold." They had all approached the large set of double doors, but it seemed no one was brave enough to actually swing them open.

"If no one else will," Eyes muttered, his glare as cold as the chilly October wind, and pushed through the entrance with the others in tow.

"Come on, Hiwatari-kun, it'll be fun."

"I don't want to have fun."

"Then.. it'll be boring."

"I don't necessarily want to be bored, either."

Daisuke pouted and tugged on his friend's arm, "Please come?"

Satoshi sighed and looked the redhead up and down, "Why can't you go alone?"

"Because it'll be scary."

The bluenette sweatdropped, "Isn't that why you want to go?"

Daisuke hesitated, "Well, yes, but..." He couldn't explain it, he just wanted Satoshi to come.

Seeing that he wasn't going to get a straight answer, the older boy rubbed his temples and shook his head, "Fine, I'll go, but we're not staying long, alright?"

"Okay!" the childlike boy agreed, smiling, "So let's hurry, I want to get there at sunset."

"Why?" Satoshi wondered, but was never answered as his bouncing friend pulled him from the school and towards an unknown destination.

---

"Here we are," Daisuke said, panting slightly from the run it took to get where they were.

Satoshi looked around and tilted his head, "This is it? An abandoned house?"

"A haunted mansion," Daisuke corrected him, "It's supposed to be cursed or something."

Nimble fingers ran through blue hair as the paler boy looked around, "I think the only thing that's going to be cursing is us if we get mugged."

"We won't get mugged," Daisuke assured him.

"That's such a relief," the blue-eyed boy drawled, rolling his eyes and heading toward the mansion.

"Be careful," the redhead warned, following close behind him, "there might be ghosts or something."

"Ghosts?"Satoshi thought, "How old is he?"

"Your boyfriend," Krad chuckled, "Tell him to grow up."

The bluenette sweatdropped, "He's not my boyfriend, shut up."Satoshi wasn't quite sure why, but recently Krad had been a lot more playful than cruel, and his jokes were well-natured instead of harmful like they had been. His angel was about the only thing in this world that could scare him at the moment, and he was doing a splendid job of it.

"Dark, what happens if I get possessed?" Daisuke wondered as the pair approached the mansion doors.

"Possessed?"the thief thought, bewildered, "What makes you think you even can?"

"Well, people get possessed all the time in haunted houses, right?"

"Yes, but you have to realize, you are already possessed."

Apparently that was the wrong thing to say, as Daisuke became slightly panicked, "I'm already possessed? How? When did it happen? I didn't even see anything." He quickly turned to Satoshi and grabbed the front of his shirt, "Hiwatari-kun, you have to get out of here, I'm possessed!"

"Niwa-kun, what in the world are you..." He sighed, "Dark-san, what are you telling him now?"

Dark chuckled, "Daisuke-kun, I only meant that I am possessing you. Technically, of course."

Daisuke released Satoshi's shirt and became flushed, "O-oh, right... I knew that."

Satoshi quirked an eyebrow but simply shook his head, "Sometimes, I think they have more problems than you."

"What is that supposed to mean?" Krad demanded, but was never answered as Satoshi and Daisuke made their way in through the mansion's front door.

"If it's haunted, shouldn't we tried to avoid it, Master Raenef?"

"But as long as you're with me, it'll be fine, right?" the cheery demon lord wondered, looking up to his teacher.

Eclipse sighed and shook his head, "It's really an unnecessary distraction. You need to continue with your studies."

"Aw, come on, it's not like I get to have fun very much."

"What are you talking about?" Erutis wondered, tilting her head, "You go off all the time when you should be studying."

"Oh really?" Eclipse wondered, looking skeptically at Raenef.

"Uh... so why didn't Chris come?" he wondered.

"Don't try to change the subject," the elder demon warned.

Erutis snickered, "Chris said that this was 'too immature for a real man like himself'." She rolled her eyes and added, "He was just trying to get out of it because he didn't want to be scared."

"I'm not scared," Raenef boasted, "Not as long as I have Eclipse with me."

"You place too much faith in him," Erutis muttered, "but don't worry, if anything happens, I'll protect you."

"You can't even protect yourself," Eclipse pointed out, idly, "How can you hope to protect anyone else?"

The girl growled and placed a hand on the hilt of her sword, "What did you say?"

"Let's not fight," Raenef suggested quickly, "Besides, we're here!" A slender finger was pointed in the direction of an old and run-down house.

Erutis wrinkled her nose, "It looks moldy."

"It looks like it's about to fall apart," Eclipse agreed, "Master Raenef, are you sure this is safe?"

"Of course, you both just worry too much." With that, the green-eyed boy marched ahead, leading his servants down the path.

"If he falls through the floor and breaks his neck," Erutis muttered out of Raenef's earshot, "I'm blaming it on you."

Eclipse glanced to the swordsmaster, "Very well," he agreed, "and if he happens to die of fright, then I shall place the blame on your shoulders."

"Hmph, fine."

"Come on, you two!" Raenef called, placing a hand on the mansion's doorknob. He blinked and looked at the door, as if trying to remember something.

"Is something wrong?" Eclipse wondered as he and Erutis joined the demon lord.

"No, nothing," he assured them, then a moment later summoned a cheery smile, "So let's go." Eclipse nodded and the three crossed the threshold. "What was that?" Raenef wondered,"What was that feeling I got just then? Like a powerful presence is inside this place."

---

"Well, face it, you look like a kid, I just thought you'd want to go out for Trick or Treat."

"I don't look like a tiny pebble the size of your fingernail that can't even be seen without a super-powered magnifying glass!"

A few people chuckled and Roy shook his head, "Fullmetal, I didn't say that."

Ed huffed and crossed his arms, "Besides, I don't like candy."

"But brother," Al interrupted, "you're always eating sweets and any chocolate you can find."

"I am not, don't take his side, Al!"

"Sorry."

"Don't take it out on your brother just because you have a sweet tooth," Roy chided, "Besides, what if he wants to go out?"

Ed blinked and looked to his hunk of tin of a brother, "You want to go out, Al?"

"Well..." the younger brother trailed off.

"It's not like he'd need a costume or anything," Havoc muttered, earning a snicker from Breda and a glare from Hawkeye.

"What was that?!" Ed demanded, getting quite huffy and ruffled.

Havoc immediately raised his hands in defense, "Nothing, nothing."

"Better be nothing," the blonde muttered before looking to Al, "So where do you want to go?"

"I have an idea," Roy spoke up, "though it might be too much for Al..."

"You're saying my brother can't take whatever you throw at him?" Ed demanded, "We can handle anything, so bring it on!"

"But, brother, I don't like-" Al began, but was cut off by Ed as usual.

"So let's go, Mustang, I want to see what you've got up your sleeve."

Roy glanced between Ed and Al for a moment before nodding, "Alright, shrimp, but remember, you're not allowed to run home, crying." The 'to mommy' part nearly slipped out, but the Flame Alchemist caught himself at the last moment.

"I'll give you something to cry about," Ed retorted, balling his fists up.

"Brother, maybe we should just go," Al suggested, a hopeful tone in his voice. The last thing he needed was Ed and Roy getting into a fight in the latter's office.

"Yeah, whatever," the older Elric sighed, "Let's go, Al."

---

"What is this?" Fullmetal demanded nearly an hour and a half later. The sun had set a few minutes ago and the night air was not cooperating with Ed's ability to keep warm. Roy had drug them out to a dark, neighborhood street and at the very end sat an old, creaky-looking house. It was large enough, and seemed that back in the day, a very wealthy family probably lived there. Of course, back in the day looked to be about a hundred years ago.

"It looks like a haunted house or something," Al commented, looking to Roy.

"Something like that," the black-haired man agreed.

"Brother, I don't like haunted houses, they're scary."

"Come on, Al, we can't back down now. If we do, then Mustang will have a field day calling me all sorts of things."

The younger brother sighed and hung his head, "Alright, but... can we be quick?"

"Yeah, sure, we'll just take a stroll through, show that ass that his little smoke and mirror tricks won't work on us, then leave."

Al timidly nodded his consent and Roy glanced over his shoulder at the siblings, "Well, are you coming, Fullmetal?" he wondered, "Or are you already scared stiff?"

"Scared?" Ed repeated, sneering, "The only thing that I need to be scared of around here is your morning breath." Roy rolled his eyes and without another word, the three alchemists made their way into the gloomy house.

---

"There are ghosts in games?" a voice asked sarcastically.

"Just play along, it'll be fun," a girl said, "Besides, you need to get out more."

"Get out...online?"

"Now, now," another, older voice chuckled, "We're here to have fun."

"Yeah!" A fourth voice, another girl, joined in, "So let's go. Teacher, are you coming?"

Sakisaka surveyed the group he had ended up with and sighed, "How did I get stuck doing this?"

Tabby latched on to the man's arm and looked up at him, "Come on, you heard Ovan, let's have fun!"

Haseo glanced to either side of him and if he didn't know better, he'd swear he was seeing double. Shino was to one side of him, while Atoli was close on the other. The gray-haired boy was still skeptical about the whole idea of a haunted area, but Atoli had mentioned it and once Tabby heard of it, it was decided that the entire former Twilight Brigade (plus a few) would go. Besides Ovan, Haseo, Shino, Atoli, Sakisaka, and Tabby, a few G.U. members had tagged along.

"You sure you won't get scared in there?" Pi asked, looking straight at Haseo.

"Just make sure you don't have a heart attack, old hag," the crimson-eyed boy replied, rolling his eyes.

"Well, just remember ladies," a certain blue-haired avatar user spoke up, "If you ever get too scared, Kuhn is here to protect you."

"The only one I want to protect me is Haseo," Endrance said, standing also very closely to the crowded Epitaph user.

"Saku said she'd be awake by now and that I should hold her place here, but... I don't think she's coming," Bo whispered, looking up to Haseo, "I don't really like scary places."

The gray-haired boy sweatdropped, "Don't worry, it's not really haunted, it's just a rumor."

"Well, if you're sure, I guess I'll go."

"How did I get stuck in such a big group?" Sakisaka muttered to himself.

"Teacher! Come on!" Tabby called from the chaos gate. She waved a hand before turning towards the object and in another instant, was gone from sight. Sakisaka sighed and soon joined her in disappearing from town.

"See you on the other side," Ovan said, glancing once more to Haseo before warping as well. Following him, Kuhn and Pi went, then Atoli and Shino.

"We better hurry," Bo said, stepping up next, "or else we might get separated." Haseo nodded and he, Endrance, and the shota boy all disappeared into their chosen area.

---

"Not much to this place, is there?" Kuhn wondered, glancing around the area that had been rumored on the forums to be a ground for hauntings. There really wasn't much to it other than some crumbling tombstones and a large mausoleum. It appeared to be an overgrown graveyard, but its true nature was anyone's guess.

"The ghosts must be really cramped," Haseo said, still unbelieving of such a thing as a haunted area.

"Well, let's look around," Tabby suggested and promptly ran off towards a far end of the area, tugging Sakisaka behind her.

"There's something odd about this place," Shino murmured, looking around, "Don't you think so, Ovan?"

"Well, there aren't any monsters," the former guild leader noted, "Only the Holy Grounds were like that."

"But this isn't a Holy Ground, right?" Atoli wondered, looking around, "It's just another area."

"It almost feels as if there's another presence here," Pi whispered, keeping her voice low and her eyes trained.

"I feel it, too," Kuhn agreed, "but I don't see anything."

"Perhaps Tabby had the right idea," the pink-haired Epitaph user suggested, "Let's look around for some clues."

"Always right on the case, aren't you?" Haseo asked, dryly, "And here I thought it's just because Yata had ordered you to be like that."

"Some of us wish to expand our knowledge," she replied, placing a hand on her hip, "and we do that through investigations."

"What is there to expand here?" Haseo wondered, motioning around, "There's nothing but a bunch of tombs."

"Haseo, look!" Atoli called from the mausoleum. She had pulled open the door and was peering inside at something.

Pi, Haseo, Shino, Ovan, Endrance, and Bo all joined her at the entrance and looked in. "What...is that?" Pi gasped.

"There's someone in there," Endrance noted, nonchalantly.

"Someone," Ovan repeated, "or something."

Haseo went to descend the stairs, but Shino's voice caught him, "Be careful."

He glanced over his shoulder before offering her a glimpse of a smile, "I can take care of myself." With her nod, he continued down the stairs until the darkness swallowed him up.

"Haseo?" Bo called after a couple of minutes, a worried look on his face.

"Where did he go?" Atoli asked, already starting to panic.

"Calm down," Shino advised her, "Us getting excited will do him no good."

"Hey, Endrance, what are you doing?" Kuhn called, joining the group just in time to see the silver-haired boy submerge himself in the same shadows.

"He went in?" Atoli gasped, stepping forward, "He's gone, too!"

"I can't find Tabby or Sakisaka anywhere," Kuhn muttered, "It's like they just disappeared."

"Maybe they went back to town?" Atoli suggested, hopefully.

Kuhn shook his head, a slight frown lining his features, "I don't think so."

"What's wrong?" Pi asked, noticing her fellow guild member's expression.

"Look around," Ovan said quietly, turning the remaining players' attention towards the area they were in, "Don't you noticed something strange about this area?"

Besides the lack of monsters and small space, something else seemed to be missing from the area. "This isn't a field or a dungeon," Shino realized, "nor is it a Holy Ground."

"Bo, where are you going?" Kuhn asked, watching as the young boy started away from the group.

"Keep in close," Shino advised.

"Don't run off," Atoli agreed.

"I'm not," the blonde-haired boy assured them, stopping a few feet away and turning back to the group, "but where's the warp portal?"

A silence fell over the group as each member looked around for the glowing blue orb. Instead of seeing its glow cast on the area, however, the only light was from the moon above. "There isn't one?" Atoli wondered, "How is that possible?"

"This is certainly an interesting area, isn't it?" Ovan chuckled, and without warning, turned down the same path as Endrance and Haseo.

"Ovan!" Shino gasped as he, too, disappeared from sight. She glanced over her shoulder, nodding to the others and followed her friend into the depths of the unknown.

"What do we do?" Atoli wondered, worry lacing her voice, "Do we follow them?"

"We don't have much of a choice," Pi pointed out, "Let's go."

"Right," Kuhn agreed and with that, the four G.U. members followed their friends' lead.

Somewhere in the real world, a man stood in front of a shadowy house, a grin slowly lining his lips. He whispered something so low that he himself couldn't hear the words. He knew their effect was taking place, however, when a barrier became visibly erect around the house. At once, the ground began to shake and the barrier fell again.

"How exciting."

And so the first chapter will end here since it's huge and insanely long. I didn't include everyone I wanted to, but I think I included enough for now. I was going to include others like Inuyasha and Naruto and a few other popular ones, but I decided to keep it relatively small. I do plan to do another crossover like this for Christmas, though, and maybe even Thanksgiving, so maybe I'll include different characters/shows then. Hope you enjoyed!
