Just so you guys know, when I copied this fanfic from the original document and pasted it to some other website, it got rid of the quotation marks, and I believe the apostrophies. Screw that..._ So I had to manually add them. If there's a few missing that you recognize should be there...then...Gomen..

Fuuka was with Kakyou and Kazuki in front of the building in the open air.

"Aww man its getting really dark out!"

Whats wrong with that? Are you afraid of the dark?

Fuuka asked playfully.

"No!! Were not allowed to go out when the sun is down. Thats when all of the big monsters are out. Its way dangerous out there."

"It looks to me like you guys can handle it. Its really that dangerous?

Kamui says so."

Fuuka watched the sun sink farther behind the tall skyscrapers of rubble and ash. Then the dusty land pattered with the acid rain that sizzled off of rocks and hills. Fuuka sighed deciding that the rain was reason enough not to go out anymore.

"Kamui? Havent you mentioned him before?"

"Oh yeah, you havent even met him yet. I would show him to you but hes probably busy."

"Busy? What exactly is he doing then? What would someone have to do here..eh, nevermind."

"Hey hey, theyre cooking that tremor that we caught earlier, lets go get some grub!"

Fuukas face scrunched up.

"Ew-waaugh! Sick. Are you seriously going to eat that?"

"Yeah, its pretty yummy..when its burnt!"

She followed the boy into the building. She spotted an area where a stairwell seemed to be placed going below. There was also light shimmering like there was water down there.

"Come on, lets go get some!"

He happily pulled Fuuka to the area where everyone was eating.

"Are you getting tired yet?"

Fai asked looking down at Ai who was right behind him.

"Me?"

"Yes you. Ai youve been following me around all afternoon like a little duck! You dont want to sleep?"

"Oh. Sleep? We dont sleep."

"We?"

They were on the second floor where all of the room chambers were. The cramped hallway had only about enough room for Fai and hyper little Ai behind him.

"Vampires rarely need sleep."

"Really?"

He stopped to look at her with interest.

"Yeah. For me only once a year is required, but I like to once a month. I like having dreams."

"So then Ill stop sleeping soon?"

"Soon, maybe in a few months youll stop sleeping. But tonight youll need lots of rest Im sure!"

Fai looked into a doorway of a well spaced dark room with a few beds.

"Well I actually am really tired right now Ai."

He sat on one of the beds. Ai leaned against a wall.

"So..dont you want to go talk to Fuuka or something since Ill probably be out like a light for at least.. oh eight to nine hours or so?"

"Actually I can just wait here."

She slid down the wall to a sitting position.

"Do you really want to sit there all night?"

He questioned balling up a blanket under his chest on the bed.

"Yeah if you dont mind."

Fai shrugged.

"Okay if thats what you want."

He layed on his stomache smiling at her.

"Good night Ai."

He buried his face in the wad of cloth. Ai just made herself comfortable and watched the way his body rose and fell with his steady breathing. Her eyes became a little irrirtated and she realized how drained she felt at the moment now that she was finally resting.

In the morning Fuuka found her way from her sleeping chamber downstairs to find the others. She was pretty eager to go chase some monsters above all.

She met the others outside the front of the building pulling their cloaks on. There were only about half of the men around, the only girl was probably busy otherwise.

"This is gonna be fun!"

Fuuka noticed her new friend there as well, she inwardly groaned, still not eager to be friendly with this annoying girl.

"So what do I call you anyway?"

Fuuka asked watching some of the others prepare their motorbikes.

"Oh I have a name now! Its A-I, Ai!"

"Ai? Thats the best you can come up with?"

"...Well I didnt come up with it. Fai-san did. Hes really cool!"

"Yeah, thats nice."

She noticed one more person immerging from the tower. She and Ai couldnt resist staring intently at this guy, his hood was down. His black hair swirled around his gorgeous face equipped with ice blue eyes. They were so charming, becoming brighter as he came nearer to the group. Slender, tall, downright stunning and they were both struck speechless.

"Whoah.."

Fuuka muttered as the guy started adjusting one of the bikes.

"Who..is...that?"

Kakyou looked over.

"Hm? That guy? That would be Kamui."

"Thats Kamui? As in the leader of your group?"

"Well...yes you can say that. He is the strongest fighter in this group. Does he peak your interest?"

"Yes- he does."

She continued to stare at the back of Kamui until she was shown to a bike. When they got within a dangerous distance of the screaching worm-like creatures, Fuuka hopped off of the bike, pumped full of adreneline.

"Alright bring it on!"

She yelled fiercly for her foe to hear.

"Wow, check her out. I am so gonna join this!"

Ai said jumping off of the back of her bike and running up to a tremor at full speed. Fuuka was fighing without any sort of weapon, and backing up to make the tremor circle. As she looked over her shoulder she watched Ais technique. She pulled two giant guns from tucked under her leg warmers and launched bullet by bullet into the monsters body. At one point it seemed like a missle flew out of her gun.

"Go Kamui go!"

Fuuka also saw Kamui fending off two tremors at once, a bit of a distance away. But she couldnt tell what he was using to fight them, especially since her tremor launched at her.

"My my, they are fiesty today."

She heard Kakyou say pretty entertained. She wasnt sure if he meant the tremors or his companions.

"Hey, how're you doing over there!?"

Ai called, blasting craters into a monster. Fuuka backed up until she was back-to-back with Ai.

"Well Id be less distracted without you yelling every few seconds."

"Im just cheering you on!"

Fuuka ran foreward to attack her target swiftly, driving the monster into the ground.

"Awesome!"

"Ai will you shut up!? If we get two distracted then we'll-"

Both of them were now facing three tremors, circling them.

"Well crap!"

She had to keep turning to watch all three of them. If she attacked one, the other two could strike. Of course if Ai were to attack at the same time, there would still be one left to attack.

"We should try to make a run for it. Chances are one of us will get past them to attack from behind."

"No way, we cant do that!"

"Then what?"

One of the three tremors screamed as Kamui landed on top of it, sticking what looked like extended claws into the tremors skull. It continued to screech and reel back, so Kamui lept off of it and onto the next one. He slid down its side slicing along its flesh to nearly cut it in half. Ai and Fuuka watched him in awe as he destroyed the opponents.

"Get away from them if you dont want to die!"

Kamui yelled at them urgently.

"Well..lets go!"

Ai pulled on her. Kusanagi yelled over at them from a few hundred yards away.

"Get outta there! Kamui will hold them off!"

Ai and Fuuka ran to an abaondoned bike and got on it, accelerating. As they drove foreward a tremor rose up out of the dirt and they drove along on top of it.

"Whoah whoah!"

They flew off of the front of it when the head came up out of the dirt, just as Kamui struck the tremor dead. They landed roughly and looked aroud at the many dead creatures, thanks to Kamui. When they decided it was safe, Fuuka ran to Kamui.

"Kamui! You were amazing!"

He had an inconsiderate expression.

"You should be more carefull in battle, try not to become so distracted."

He advised. Fuuka huffed wanting to say that the problems were Ai, but she held back.

Then she gasped as rain fell on her. As it sizzled on her bare arms she cringed and held her arms around eachother. When she started towards a bike, she was suddenly shrouded in cloth as a cloak was dropped on her.

"Eh? Eh?"

When she pulled it off of her eyes she just saw Kamui walking up to his bike and mounting it.

"Hey, get on."

He told her.

"Uh.."

"Just get on now."

He said loudly. She quickly got on behind him.

"It should storm."

He said accelerating.

"Really? How can you tell?"

She asked holding securely to the back of his seat.

"The water lets me know."

He replied, Fuuka just decided not to ask quite what that meant. As they gained speed behind all of the others, the rain began falling more intensely.

^Ohh, he doesnt even seem bothered by the rain. ^

(((IF YOU GUYS CAN'T TELL. THE '^' SYMBOL LABELS THOUGHTS!!)))

She pulled the hood a little more snug around her shoulders.

"I'm gonna go faster, hold on."

She clenched her fingers around the seat bottom.

"Got it."

He looked over his shoulders and scoffed, then momenterialy had to take his hands off of the handles to grab her hands and put them around his waist. She blushed but really liked the feeling of his fit body.

"Hold on tighter or youre falling on your ass."

He threatened revving the bike to go about twice as fast. She had to hug tightly to him to keep from flying off of the bike. But she also enjoyed that a lot.

"What is that?"

She asked looking at what looked like an underground cavern that she saw in the distance. Kamui slowed his bike to a stop surprisingly.

"Do you want to check it out?"

The only others that saw him was Kakyou with Ai on his bike.

"Kamui what are you doing? Its pouring!"

He shouted.

"She wants to see the caverns with the spirit. Might as well show them, its the nicest place here."

Kakyou rolled his head back sighing.

"Fine! Lets make it quick."

The two drivers went towards the cavern entrance and the four of them entered.

"So what is this place?"

Ai asked looking around. Deeper in the cavern cast a strong glow.

"I'll sit here, the lights give me a headache."

Kakyou took a seat on the stone floor far enough in the cavern to stay dry.

"Do what you want Kakyou."

Kamui said with an uncaring tone, leading the girls farther into the cave. They came upon a breathtaking sight. The focal point was an enourmous tree that looked translucent that glowed brightly. Around the base of the tree was an island of unatural looking patches of plants and floral. Smaller bushes around the trunk held fruit. Beyond the island was a huge lake of crystal clear water.

"This place is so...beautiful!"

Ai walked towards the water.

"That isnt water."

Kamui said before she could do anything harmfull.

She did, out of curiosity, stick her toe into the lake, the tip of her shoe didnt errode, but it sizzled.

That is more dangerous than the rain here. Keeps anything unwanted away from that bank.

He nodded towards the tree.

"What is this place?"

Fuuka asked.

"This may be explained as...well, holy I suppose in a way. A powerful spirit lives in the tree and keeps anything unpure away from here. He also raises spirits."

"Can I go over there? That shore?"

Kamui tilted his head.

"You think you can walk on that lake of flesh-eating acid? I want to see that."

"Well no! I can jump it!"

He chuckled.

"Can you?"

I sure can!

He shrugged and leapt gracefully over the water to the shore. Fuuka took a running start and jumped over as well landing in front of him.

"Impressive."

He watched as a small fox immerged from the tree, he looked whispy like smoke. A spirit Kitsune.

This Kitsune is the guardian here.

"Wow..."

She stared at its cerulian eyes.

Ai sat on the other side of the lake looking a little drowsy as she stared at the water surface.

"What is this?"

She pointed to one of the fruit that was clear, looking like a strange gel molded into a pear-like shape.

"Those are a certain fruit that...well, the only fruit available here at all. You could try one, but it is absolutely forbidden to take it away from this tree."

"Uh huh."

She picked one and bit into it. When no one was looking she snuck one into the sleeve of her kimono.

"Completely pure here. Even the grass."

Kamui said.

"Sould we head back about no-aawwaahhh!!"

She shreiked as the Kitsune chomped on her wrist.

"Ahh!! OWWIE!"

She yelled grabbing her wrist and the fox hissed and ran into his tree.

"What just happened?"

Kamui asked looking at her wrist. No punctures but a mark appeared.

"What did you do to him? He gave you a curse!"

"Well..I.."

She sighed pulling the fruit out and tossing it.

"You tried to steal a fruit, well look where it got you! Smart idea."

"I didnt.."

Ai seemed to suddenly snap her head up.

"Huh? What happened?"

Fuuka and Kamui jumped back over the water to show Ai.

"Yeowch. All that for a fruit?"

Kamui looked over the mark.

"I've seen this mark. Stupid Fuuma had it before, but found a way to have it removed because he can schmooze anyone. This mark should mean that...anything you eat will spoil in your stomache. If you eat, youll regurgitate. Simple as that."

Fuuka scoffed.

"No way! That...mean fox! I only-"

When she moved, her heel caught on a stone and she started to fall backwards- right into the acid. In a flash Kamui jumped into the acid behind her to catch her right before she could hit the surface. Steam rose from the water and he groaned as he pushed her back up onto her feet.

"Agghhhhhh....be..."

He jumped out of the acid quickly, rubbing his irritated legs.

"..more carefull."

He said sounding angry.

"I'm so sorry Kamui! Im really-"

"Just dont touch me."

He said pretty coldly. Fuuka stared guiltily as he started walking towards the exit.

"Let's head back before the storm is too rough."

"Ohh, you took a nasty spill there Kamui?"

"Let's go."

Ai looked a little sluggish on her way to Kakyous bike.

"Feeling okay there?"

"I just really need rest I think. I wont fall off the bike, I promise."

"Good, cuz Im not cleaning you up."

Fuuka reluctantly came towards Kamuis bike, forgetting about the rain falling. Kamui just looked at her and lifted her hood up for her.

"Return this later. And I didnt mean to snap at you, it just hurt."

"I'm sorr-"

"Don't apologize. Its not your fault you probably cant maintain your balance normally."

He smirked humorously and started the bike to head back.

When they were back in the building, it was pretty stormy out there. And upon arriving at the Tocho, Kamui dissappeared before Fuuka could return his cloak.

"Hey...whats up with you?"

She asked when she watched Ai lean against a wall.

"I dont feel good. Like..ugh, Im so exhausted."

"That bad? All I can say is you need sleep."

"Right, got it."

She made her way to the upper level where she spotted Fai in a hallway peering out an open window.

"Such toxic acid rain, yet when it falls the air smells clean and crisp."

He said brightly.

"Am I supposed to sleep for about 24 hours?"

"Well..not a bad sign. Should be at least 48."

Ai said slinking down the hallway. Once she felt the cooling breeze from the rain she just sat against the wall below him.

"I had some disturbing dreams. And when do I start craving blood I wonder? I havent read up on vampires for so long."

"Weird dreams are normal, and you will still rely on human nutritions for maybe a few weeks, Im not sure. It probably varies...ughh."

She ran her hands over her face that was losing color. Her throat was burning with thirst for....the only thing that she could.

"How long has it been....?"

She muttered quietly to herself.

"About three years or so..dammit this sucks..so dizzy.."

Her head fell into her lap with a sigh. Fai looked down at her and bent down to her.

"Hey, Ai-chan whats wrong with you?"

She murmured something incomprehendible. He nudged her.

"Ai?"

She didnt respond.

^Is she in trouble?^

Fai nearly jumped when she heard someone speak without hearing the footsteps. The teenager at the end of the hall had dark, delicate hair framing his face and blue eyes. His cloak had half of a tall collar hiding some of his face. Kamui was with him as well.

"You're the other twin brother. Kamuis brother am I right?"

Fai asked, remembering seeing this guy in the room where he was fed blood to become tranformed.

"Call me Subaru."

Subaru offered his own blood for Fai but Kamui stopped him.

"She looks really out of it. Can vampires have fatigue?"

Fai asked. The twins came to look closer at her.

"Yes we can."

"Clearly they already knew about her being a vampire as well."

"Simple. She needs to have blood soon or shell probably die. She told me the last time she fed was nearly three years ago. That is about a limit for someone her age."

"Three years? So shes dying suddenly?"

"It can strike quite suddenly after exserting a lot of energy. Now do you know what you have to do?"

Fai frowned at him.

"Feed her?"

"She must not have her own Provider so there should be no problem taking blood of anyone. I swore not to give my own blood. Fai-san is she important to you?"

Subaru asked as Kamui quietly watched.

^I don't want her to die.^

He thought.

"Those others at the tower that you are rivaling. That Fuuma person isnt exactly important to you is he?"

Fai asked. Both twins looked a little appauled.

"Do you really think that is a good idea? To kill Fuuma and use his blood for the girl? Although perhaps then you can get your first taste."

Kamui replied clearly. Subaru felt one of Ais pale and dry hands.

"Well she will be gone very soon unless you are willing to let her drink off of you."

They looked at Fai and stood to leave.

"Your decision will need to be soon."

Fai sat in front of Ai, lifting her head up a bit.
