Cold, god dammit why is it so cold! And why does it fell like someones branded a hot iron on my side and shoulder! Is it even possible to feel fucking freezing and magma hot at the same time! God I'm going to kill that stupid pacifier breath for even sending my on this mission in the first place!

Mission...

Oh, that's right. Koenma sent me Kurama and Hiei on a mission to kill an A class demon... but then what happened...

Ok, lets start from the beginning,... I remember being late to the meeting place and then...

...Story Begins...

Our hero, Yusuke Urameshi was sitting on the roof of his newly acquired home, quietly enjoying his first day off in years. Ever since the end of the demon world tournament, things had changed. Upon his return to human world, life was normal, Kuwabara had gotten accepted into some prodigious collage, while he had decided to quit and work full time as a rouge spirit detective and demon lord. He'd also opened up a new ramen shop in town that was doing well in paying the new house bill. He could have used the money form his castles treasury, but the thought that it still belonged to Raizen still ran through his head.

Sighing in bliss as the sun hit his shirtless toned, muscled chest, Yusuke closes his eyes and smiles.

Oh and here's the real kicker, after a year upon his return, Keiko and him had broken up. Yusuke had realized that now that he was a demon, he would live a much longer life span than Keiko's human one. Not wanting to go through the pain of Keiko getting older while he continued to stay the same, Yusuke had made his decision to brake up with her. Of course, he'd be lying if he said that was the only reason. In truth, ever since his demon nature had first woken, Yusuke was beginning to have feelings for a certain Kitsune and Koorime. He'd heard from Kurama that it was natural for demons to be bi, but that still didn't help with the friends, rivals, and partners issue. Plus, he was pretty sure Hiei and Kurama were a couple, even though the two had never said anything out loud.

Sighing once more, Yusuke is about to lift his arm over his eyes when a voice from behind startles him enough to almost send him tumbling off the roof.

"Didn't your mother ever tell you sitting on the roof could be dangerous."

Opening his eyes, the former Tantei bolts up and looks up to one of the causes of his most resent dilemma. Hiei, a former member of the once team Urameshi, stood at his normal stature of about 4'10'' with his usual black cloak on and grumpy nature. With his katana on one hip, black spiky hair with a tint of blue deifying gravity, and hands disappearing into concealed pockets, the Koorime was the picture of bad boy.

Standing to his full hight, Yusuke looks to the Koorime with a smile and asks, "Wow, Hiei, its been awhile, and what do I owe the pleasure of seeing you here?"

Grunting in greeting, the shorter demon walks up to Yusuke while hiding the admiration in seeing him with out his shirt on.

Stopping a few feet away, Hiei drags his attention to the demon lords face and states, "Koenma asked that I inform you that you, me and Kurama are to report to spirit world immediately."

With anger rising to the surface, Yusuke looks on in disbelief at the fire apparition and yells, "Are you kidding me! It's my first day off in months and that toddler has the nerve to call on me for help! Forget it, I'm not going!"

Smirking Hiei looks to the fuming Tantei with humor in his eyes, "He also said that if you refuse to come then I have permission to force you in anyway I so choose. Even if it means dragging you there by your toes."

Noting the challenge in the others voice, Yusuke looks to Hiei with an all knowing smile and responds, "I don't know Hiei, you think you can stand up to my bruit power?"

"Do you think you can keep up with my alarming speed?" Hiei counters.

After laughing for a brief second, Yusuke lowers himself into a fighting stance as Hiei does the same.

With fists ready, Yusuke shouts, "Bringing it on short stuff!"

With a grunt and a muffled "Fool" under his breath, the two raise their demon energies and launch at each other.

Who wins? Only time will tell.

...In Spirit Realm...

In spirit world, the red haired Kitsune watches as Koenma paces the room with a stressed look on his face. The god was currently in his teenaged form, with his usual brown hair and noble robes sliding gracefully down his form. After circling the room half a dozen times and glaring at anyone who dare came into the office with paper work, Koenma finally stops and looks to the Yoko with a glare.

After observing the boy for a brief moment, Koenma growls, "They're late."

Chuckling as if it were a joke, the Kitsune responds, "Well it is Yusuke we're talking about, it's not unusual for him to be late. No doubt he's arguing with Hiei right now about his promised day off."

Sighing, the Jr death god lowers his eyes and walks around the desk to sit in his normal chair.

Folding his fingers and lowering his head to lean on them, Koenma grumbles "I know, but I wouldn't have called if it weren't something dire. Yusuke should know this by now."

Walking over, Kurama silently seats himself to the right of the gods desk and responds, "I'm sure he understands that to an extent, he just refuses to acknowledge it."

"We'll for human kinds sake, he'd better acknowledge that part of him soon, otherwise we're going to see the death rate of humans increase in a matter of minutes."

Suddenly jerking his head to the side as if he'd heard someone, the red head smiles and states, "Well then you're in luck, they've both just arrived."

At that moment, a dark figure bursts into the room and throws a half naked stunned teen to the floor. While the dark figure; now recognized as Hiei, walks over to Kurama, Yusuke sits up and glares at the Koorime from his spot on the floor.

Slowly getting up, the ruffed up teen continues to glare holes into his teammate and almost shouts, "No, fare Hiei! You said we couldn't use any of our signature moves!"

With a smirk still in place, the short demon snorts and responds, "I never insinuated we couldn't use them, you simply made up those rules on your own from the start."

"Whatever cheater."

"Incompetent fool" Hiei retorts.

"Fire brat!" Yusuke shouts.

Hiei just loved getting Yusuke rilled up, it made his human form look more transparent in comparison to his demon, and this was no exception. "That's funny", Hiei grins "Last time I checked I'm much older then you are Detective. So if I'm a brat, what does that make you pacifier breath."

Using Yusuke's normal nick name for their boss, the teen is about to launch at the fire demon when Kurama steps in between them.

Calmly, Kurama walks over to their leader and brushes a delicate hand up the center of the Tantei's still naked back and stops at his shoulders. Soothing the Detective instantly, Yusuke closes his eyes at the feeling of skin on skin and opens his eyes to witness Hiei looking over to the Kistune with an expression he'd never seen on the apparitions face. But before Yusuke is able to identify what it means, the Koorime replaces the look with that of his usual glare.

Grinning, the Kitsune leans into the demon lords ear and is pleased to feel the shiver run through the others body as he whispers, "Now is not the time for fighting Yusuke, save that till after the mission. Then you two can spare with each other to your hearts content."

Removing his hand, Kurama turns and mentally gives Hiei a message to behave as he faces the Jr. death god.

In a gentile voice, Kurama asks, "So how can we help you this evening Koenma?"

Getting up off his desk, Koenma walks over to stand in front of the three and looks each in the eye before his gaze falls on Yusuke, "I'm sorry I forced you to come here during your vacation time and I promise to pay you back in full upon your return."

With his anger gone, the former Spirit Detective sighs and gives his shoulders a slight shrug before answering, "It's fine Koenma, even in death you know you can always count on me. If I don't take care of your mess than who will?"

Chuckling, the Jr death god responds with a smirk, "Not Hiei or Kurama, that's for sure."

Ignoring this, Hiei asks, "Speaking of teammates, where's the ugly oaf?"

Grinning down at his teammate Yusuke retorts, "Why Hiei, don't tell me you miss him? I didn't know you cared so much for him. Wait till he hears that."

Glaring at the teen, Hiei simply answers, "It's just quieter with out the banter of two useless fools going off the entire day."

"Hey!" Yusuke manages before Koenma cuts him off and continues.

"Kuwabara won't be joining you on this mission. The area I wish to send you is not safe for humans, even strong ones like him." Koenma states.

Contemplating this, Yusuke asks, "How bad are we talking."

"The place I am sending you to is called Mt. Toukan Sendo, otherwise known as Mt. Frozen death. On a good day, the temperature is minus 100 decrease and at worse can reach beyond negative 1000, with high winds. Hiei, Kurama, I'm sure you've heard about this place."

"Yes, I've never actually been but I've heard even demons have trouble surviving in that area. The wind and snow make it near impossible to see and it's in the top five of being one of the most freezing and dangerous parts of the Makai" glances at Hiei before continuing, "I've also heard there's a lake near the top with a forest around it named lake Yukina."

In surprise, Yusuke looks down at Hiei with a questioning gaze.

Shrugging, Hiei responds, "Your sources are correct, it's almost exactly as you described it. Only, the mountain itself is not nearly as dangerous as the lake. Lake Yukina is the coldest water in all three worlds, if you fall in, you're almost certain to die."

Nodding Kurama adds, "I can count on one hand the number of demons who've survived taking a dip in its cold depths, Hiei being one of them."

"What!" Yusuke exclaims, "Hiei, you fell in there?!"

Looking away from the others, Hiei states, "I didn't fall in, I was dropped. Mt Toukan Sendo, is just below the floating island of the ice maidens land, my birth place. When I was just a baby the ice maidens dropped me off the edge of that cliff into Lake Yukina." Looks to Yusuke, "You remember me telling you that story right?"

Nods, "Yeah, but you never said you fell into a lake. How did you survive?" Yusuke asks.

Shrugs his shoulders, "Being a fire demon has its perks." Turns back to face Koenma, "I'll tell you the rest at a later time." Hiei finishes.

Nodding his agreement, Yusuke turns his attention back to the Jr. Death god and asks, "So what do you want us to do exactly?"

Clearing his throat, Koenma continues, "Keep in mind this mission didn't come from me or Spirit world. It actually came from demon world as a distress call from the lake spirit her self. Yukina, preferably known as Yuki is a very kind spirit who is known for her beauty and grace. Due to her shyness, she hardly ever comes out of hiding and thanks to that, no one has seen her in over a millennia."

In a questioning tone Kurama asks, "When you say spirit, do you mean spirit as in phantom or as in godly stature?"

Chuckles, "I new you'd ask that" Koenma continues, "Yuki is a nature god spirit, she lives and protects the land below and above Mt, Toukan Sendo. Her status rivals my own in some areas."

"So did she turn evil or something?" Yusuke plainly states.

Shaking his head, Koenma responds, "No, she's to pure for that." Mumbles to himself, "Maybe some one polluted the area near her, or worse some ones kidnapped her."

With frustration and confusion, Yusuke ask, "Ok you lost me, if this Yuki person is a god, why can't they just fix whatever's wrong with there power. And how do you even know this god is in danger in the first place?

Turning to his team mate, Kurama answers, "Nature gods don't really have any power, so to speak. All they can do is manipulate the area in which they protect. In Yuki's case, summoning wind storm, avalanches, hail and other nature elements. But if something happens to the area they protect the god becomes weaker"

"So in other words, you think someone may be threatening the lake spirits area?" Yusuke responds.

"Precisely"

Turning to Koenma, Yusuke retorts, "That still doesn't answer my second question, how do you know they're in danger?"

Turning to his desk, Koenma grabs a sheet of paper and holds it up for the team to see. On the letter was a single word, 'Help'. "This letter arrived this morning from Mt Toukan Sendo, along with this to prove its where a bouts." Sticking a hand into his pocket, Koenma pulls out what appears to be a beautifully white snow flake.

In confusion, Yusuke looks to Koenma and questions, "A snow flake?"

With clear fascination in his voice, and a brief gleam of his past treasure hunting self, Kurama answers, "Not just any snow flake Yusuke, it's called a snow crystal, an extremely rare item in the Makai. It's said that even in the hottest desert this crystal never melts and even cures the most heated fevers." In awe, Kurama looks up to Koenma and asks, "Where did Yuki find this?"

With a rare smirk, Hiei looks to Kurama and retorts, "She's a goddess Kurama are you really that surprised? She probably made it using her own energy."

Looking at the smallest member of their group, Koenma cautiously responds, "I'm surprised you know so much about her Hiei, perhaps their is something you're not telling us?"

Looking away, the fire demon makes a soft grunting noise and walks to a chair in the corner of the room.

Turning his attention to the other two, Koenma states, "Your mission is to travel to Lake Yukina and find out if their's trouble. Botan is getting the portal ready as we speak, so if their's no more questions I'll meet you in the hall in five when it's ready." Taking a step forward, Koenma hands Yusuke the snow crystal and continues, "This will help guide you to your destination as well as confirm whether or not the goddess is in danger. If it starts to melt it means she's weakening." After handing Yusuke the crystal, Koenma is about to leave the room when Yusuke speaks up.

"Um I know I'm this so called all powerful demon lord, but their is no chance in hell I'm walking into -100 degree weather with only jeans on. I'll need to head over to my place to grab some cloths because some one...," Glares at the Koorime as Hiei fain's innocence, "Dragged me here before I could."

"Their will be no need for that." Snapping his fingers, an ogre walks in from the same door and hands Yusuke a pile of cloths. "Those should do just fine, now if you'll excuse me." Koenma walks out but before the door closes, Yusuke yells.

"And how do you know I'll like these cloths! And how do you even know my size creeper!" Koenma ignores this and the door closes, leaving the three of them alone.

Now pissed, Yusuke places the crystal on the floor next to him and begins looking through the cloths while mumbling, "Stupid pacifier breath, stupid cold, stupid mission..."

While ranting, Yusuke observes the clothing Koenma had given him. Among them was a solid black inner shirt with long sleeves and a jacket that resembled the one he usually wore but with extra warmth. Under those, were a pair of shoes that resembled Hiei's, oddly enough along with sweat pants that were black as well.

Looking up, Yusuke briefly ponders where the bathroom is before realizing their wasn't one. Observing the other two in the room, Yusuke was about to ask them to turn around when another thought crosses his mind. Even if they didn't react, the thought was still entertaining to see through. Plus he'd be damned if he asked the two guys he liked to turn around just because he was embarrassed.

Shrugging, Yusuke concludes his thoughts with a mental, 'well, here goes nothing' and proceeds with his actions.

Turning away from the others, Yusuke purposefully bends over while exposing his ass in order to retrieve the crystal from the floor. Unknowing to the former tentei, both Hiei and Kurama struggle to control their instincts to jump the carless detective.

Glancing at his mate, Hiei smirks at the expression of hunger upon the Kitsune's face.

Using their mental bond Hiei states, 'Carful fox, otherwise he'll notice the animalistic grin on your normally angelic face.'

Still gazing at the now standing Yusuke, Kurama responds mentally and smiles, 'Don't pretend you're not interested love. We talked about this, and you admitted to wanting him too.'

Pausing, Hiei looks back to notice Yusuke had placed the crystal upon Koenma's desk and was now slowly removing his pants. Hiei couldn't help but lick his lips at seeing the surprise that was now in front of him.

Instead of jumping the detective right then and there, Hiei manages to control himself and chuckles, "Wow Detective, going commando are we?"

Blushing, Yusuke ruffly pulls on the new sweat pants over his perfectly round ass and retorts, "I wasn't exactly planning on being anywhere today. Plus a certain fire brat dragged me to spirit world before I could grab anything."

Mentally Kurama states, 'cu-do's to the fire brat.'

Successfully hiding the smile from rising to his lips, Hiei observes as the detective finishes tying the strings to his pants. With lust filled eyes, Hiei watches as Yusuke's ab muscles clench and lengthen as he continues to dress his upper body.

"Perfection" Hiei whispers so only Kurama can hear, then mentally adds, 'If I didn't know any better, I'd say he's doing this on purpose.'

Chuckling to himself, Kurama adds, 'So it would seem, but their's still the fact that we need to be carful when approaching him with our feelings. Yusuke maybe a reborn demon, but that still doesn't change the fact he grew up in a species that rejects same gender relationships for the first part of his life. Before taking action, we must make sure he is willing first.'

With an all knowing smirk, Hiei responds, 'But that doesn't mean we can't play with him until then.'

'Of course.' Kurama concludes, ending their mental chat.

Now the detective wasn't clueless, he new the other two were conversing behind his back but whether or not they were about him he couldn't tell.

Sighing at his failed attempted to get a emotional response out of the two, Yusuke turns

around fully clothed with the crystal in his pocket and states, "Alright, we all set?"

Meeting his eyes, Hiei speaks with amusement in his voice, "We're all ready, just waiting on the woman of the group to finish getting dressed."

Glaring at the shorter demon, Yusuke gives him the finger and walks ahead of the group and out the door with the others not far behind. Once out, an oger leads them to the portal where Koenma and Botan are waiting.

Turning to the three, Koenma's gaze falls on Yusuke and asks, "Thous cloths suit you well. I trust they're suitable to your needs?"

Stretching his arms, Yusuke tests the material and answers, "Oh yeah they'll due, though I'm still creeped out you know my size."

Ignoring the punk teen, Koenma looks to the more responsible of the group and asks, "You under stand the mission?"

Nodding, Kurama answers, "search the area and check to see if anyone is harming the goddess."

"And baby sit the detective to make sure he doesn't cause problems," Hiei adds.

"Shut up Hiei!" Yusuke shoots back from Hiei's left.

Rubbing his temples in irritation, Koenma looks to Kurama with wonder and asks, "How do you control these two?"

Chuckling, Kurama responds cheerfully, "It's easy once you know how."

Secretively, Kurama lifts his hand away from his side and pinches the fire demons ass suggestively, while giving the demon lord a seductive glare. Both holding back a moan from rising to the surface, they instantly shut up and observe the ground.

With an all knowing smirk on his face, Koenma turns to the blue haired reaper and asks, "Are we all set?"

"Bingo we're all ready!" Botan exclaims, "One portal to Mt Toukan Sendo!"

Turning once more to the boys, Koenma says, "Good luck you three, and don't cause to much damage, Yusuke, Hiei." glares at the two.

Waving his hand nonchalantly in the air, Yusuke and the others walk forward into the portal as he shouts behind him, "What ever diaper man, we'll be back soon."

As all three disappear into the portal, Koenma shouts back, "I told you to stop with the nicknames!" and they're gone...
