AW: SO! This is pretty much my baby that I've been nurturing since 2004 or 05. It's gone through many changes and I've decided to change it up just a little bit as I have with other older stories of mine to be more up to par with my current writing and mindset. But the plot is generally the same as well as the OCs I have made for it before. Please enjoy and don't be afraid to be critical with me in the reviews. I will however ignore ( or laugh at ) flamers. Thank you!

Disclaimer: I do not own Yu Yu Hakusho or any of its characters. This will be the only time I do a disclaimer so there aren't too many unnecessary words from me. :3

Mysterious Detective

A girl with long, dark brown hair put up into a high ponytail with dark brown eyes walked into Koenma's office, which happened to be empty at the moment. His absence annoyed her as she was a busy person. She wasn't here for charity. Aside from the pay, she had a personal reason for becoming his Spirit Detective. She had hid her identity from him and seemed to be just an extraordinary human that attracted his attention when she was constantly found at the scene of rogue demons being tracked down in the Human World. She was sure Koenma was slightly suspicious of who she might be since she was too good at finding and killing these demons. Not to mention in a rather clean way. No blood, or even body, left. But she wasn't the least bit worried. The toddler wasn't the smartest creature she'd ever met. She wondered often how he could be the Prince of the Spirit World. Ah well, we are born to our life, we don't choose it. Or even reborn into lives that fit our needs. As she would eventually find out later.

Settled on the edge of his desk, the girl smoothed the skirt of her school girl uniform for Meiou High. She always loved the red of the uniform and thought it was rather funny that the males at her school were made to wear pink. She wouldn't have minded the colors being switched. She had been fortunate enough to enter a rich family when she escaped to the Human World. She'd gone to all the best schools in the area and, due to her intelligence and former life, was fairly distant from everyone around her. She didn't care too much about others but gave enough respect to where they couldn't complain. She just wasn't an enthusiastic person nor did she like idle chatter with humans. They did talk about trivial things. If only they knew that there were apparitions around them; that there were dangers lurking and they lived so ignorantly. Then again, ignorance is bliss.

The girl sometimes envied them. She wished she didn't have to experience what she had and could forget about it all. Like the recent amnesiac cases that had popped up. There were many of them and all of the victims were thieves. It was a curious thing and it drew her in, wondering why thieves were targeted. It was an old profession of hers when she used to live in the Demon World. It made her think about the one reason she couldn't possibly forget about her past. She had to know if he was still alive. She was quite certain that he was. Even if he had been reported dead after being supposedly run down by one of the Special Defense Force. She didn't believe it. Then again, around the time he seemed to be extremely distracted. To be honest, she had been as well. Their childhood friend, Kuronue, had died and the two had gotten careless. But she didn't think it was to the point that they could be killed. They'd lived too long for that and even while careless, they were still quite strong.

'He has to be alive. Perhaps like how I escaped…' but she was unable to finish her thoughts as Koenma finally returned to his office with that bubbly blue-haired girl, Botan. They both froze when they saw her sitting there, a rather annoyed look on her face.

"Shizuka?! What are you doing here? How'd you get in my office? And don't sit on my desk! It's rude!" Koenma yelled at her, still quite shocked at the human girl's appearance. He settled in his chair and watched as she merely turned to face him better, still sitting on his desk.

"You called me, remember?" Shizuka looked at him through half-lidded eyes, quite annoyed at his selective memory. Her face scrunched up slightly in disgust as he began to stuff his face with the food he walked in with. She turned to Botan, "How do you stand to work for him? Your job isn't even enviable to stay for. Then there's him."

Botan giggled nervously, "Oh, you know, Shizuka, it's not too bad. I suppose I'm just used to it after all these years."

"Vague. Quite smart, I suppose. He is your boss."

"I'm currently your boss too, Shizuka." Koenma reminded her, causing her to hop off of the desk to avoid food particles flying at her from his full mouth.

"You truly disgust me. How one of your status can eat in such a barbaric way is beyond me." Shizuka sighed and crossed her arms over her chest. "So, another case I take it? Is it part of the chain of amnesiac cases?"

After swallowing his food and ignoring her usual condescending comments, Koenma nodded, "Yes and this time they got the thief. The King of Thieves. I don't know how they find all of them but whoever is doing this is probably targeting them as only a part of their plan. I'm afraid of what will happen if they could wipe his memory."

Shizuka had to hide her surprise. He couldn't actually mean…? No, that would mean Koenma knew him and she'd been incredibly close to finding him this whole time! She clenched her hands into fist, attempting to calm her racing heart and slow the sudden quickness of breath.

"King of Thieves?" Shizuka played dumb, glad that neither of them noticed her initial reaction. "I suppose that shouldn't be too surprising. There is a caste system for every type of profession."

"That's not important! We need you to restore his memory to see if he can remember anything!" Koenma once again shrieked at her in that annoying toddler voice of his.

Shizuka shook her head, used to this, "I've told you before. Every time I've restored the memories of those thieves, they couldn't remember anything after their memories were erased. I could restore their long term memories of everything up until the point in time of when their memories were erased. Do you have amnesia?" she sighed in irritation at his lack of sensibility. Though she was already thinking about how to restore his memory and seeing if she could find the bastard(s) who dare touch her brother. Those memories they took away were very important. How ironic that she would finally find him only to have him not know who she is. Of course, in her current form, he wouldn't have known anyway. But still, it was going to be painful.

"Well, try! Besides, he's different from any of the other thieves. I'm sure they weren't able to wipe all of his memories. He's lived over a thousand years, after all." Koenma sat back into his chair, stuffed. "He's currently at Genkai's temple. It's the safest place for him and for everyone else. I have my best detectives guarding him."

"What do you mean, 'everyone else'? Is he dangerous?"

"He seems to have reverted back to his old form and withheld some memories from his past life. More so of his heists, not so much of the people of his past. Whoever is doing this is a really good magic user." Koenma sat up a bit a looked at her with a serious expression for the first time. "You have to help him. If they find a way to get to him, who knows what will happen."

Shizuka's heart stopped when she thought he might still remember her before it ached after Koenma finished his statement. 'This is not going to be easy. I can tell. And not just because I have personal attachments to this case. If they can be so selective, they must be really good.' She sighed and nodded to Koenma. 'But I will kill whoever the hell is doing this.'

"Well, I won't waste any more time." Shizuka turned and walked out of the office, her heart racing once again, her breathing laborious. 'Brother, regardless of the situation, I'm so happy you're alive.' She was beginning to tear up slightly but immediately wiped it away. She couldn't let her emotions get the best of her. There was much to do before she could have a proper reunion. It made her hate whoever was behind this even more. She couldn't wait to solve that particular part of this case and put a face to the person or people involved.

Shizuka knew somewhat of the other detectives, thanks to Genkai. She was rather close to the old woman who had helped her train in this human form. During her training she talked mostly about Yusuke and Kuwabara. She had never heard about anyone else. Perhaps it's because she's never trained Kurama or Hiei. Not that she had to, Shizuka was sure. Demons tended to train on their own. She only sought out the woman because she wanted an expert to help her. She had told Genkai everything in exchange for her help. She wondered why the old woman hadn't told her about her brother. She knew a lot about demons. 'Maybe she just wanted me to find him on my own… sentimental old woman.'

Shizuka shook her head as she made it to the top of the stairs, a bit hesitant to continue forward. She could sense him and smell him. It brought her wave of happiness that almost caused her to cry again. She took deep breaths to calm herself again. She needed to reign in her emotions. She was here as a detective first. She hoped to have plenty of time to catch up with him after the many years they'd spent apart. But after this case was solved. Why did she feel like this would be a long ordeal?

Her thoughts were interrupted, however, as she felt the presence of an unfamiliar demon. He was a fire demon and had a lovely scent. He smelt of nature and of the wind. She could also feel his eyes boring into the back of her head. How had he gotten behind her so quickly? She turned slightly and met with the crimson eyes of a black-clad male perched in a tree. He wore quite the glare and she met his gaze steadily, raising a brow slightly.

"You're one of the other 'detectives' guarding this King of Thieves who has become another victim of these string of amnesiac cases?" Shizuka studied him and watched as he quickly made his way to block her from entering the temple.

"Hn. How would a human know about all of that? Just who exactly are you?" Hiei wore his cloak but she could hear the slight shift of cloth as he readied to fight her if necessary.

Shizuka gave a dry laugh, "Oh, if I was a mere human, would I even show up here?" she rolled her eyes at him, "I am actually another of Koenma's detectives. Not so well known. I do special cases that cater to my expertise." she crossed her arms, slightly annoyed that he was blocking her path. "Now if you could move so that I can do my job?"

It was Hiei's turn to laugh, "Even if you could get close to him, I doubt you would be of any help. If I couldn't help him then how will you?" Of course, Hiei had been informed by Genkai that a girl would be coming to help Kurama but he didn't trust anyone getting so close to the fox, as vulnerable as he was. No matter what he was told about her, the fact that he couldn't do anything to help his friend put him in a rather sour mood which made him all the more protective of Kurama.

A bit of surprise flashed on her face for a moment, "A Jaganshi. I see. Well, considering a spell did this, your Jagan is somewhat useless. No offense." she could see why he was being the way he was. Aside from probably being suspicious of all strangers, he was quite upset that he couldn't help Kurama, who she supposed he was close to. She was glad that her brother was well guarded. But this particular guard of his needed to get out of her way so she could restore her brother's memories. Hopefully it was the same spell as the others. The spell seemed to get progressively stronger as the culprit went up a list of some sort. Because she knew a lot of the thieves targeted and they did go up in power level as the cases progressed. She had a feeling this particular spell might actually give her trouble. She was sure they had to try something different on a youko, who has lived at the very least a thousand years.

Just as Shizuka was about to threaten Hiei to move, a raspy old female voice made them both turn their focus away from each other and towards the owner of this temple.

"Hiei, let the girl through. She's here to help." Genkai walked passed the fire demon and took Shizuka by the hand, pulling her onto the temple grounds. "Now you get in here so that this poor soul can get all of his memories back and maybe we can find out who is behind this."

Hiei growled and went ahead of them to make his way to where Kurama and the rest of them were. He hoped Koenma knew what he was doing, sending a mere human to help Kurama. She'd have to be able to get close enough to him before she could do anything and he wasn't even letting any of his friends close to him. Not to mention he had reverted to his old form so he was even stronger than before. It was a lucky thing Genkai was there with them. She helped keep Kurama in check and the rest of them tried to keep their distance but made sure to keep track of him. He just really hated how he couldn't do anything but this random girl was supposed to be able to help him? It really was infuriating.

"I just sensed a new person. That girl showed up, I'm guessing?" Kuwabara was met with silence, as per usual with Hiei lately. He completely ignored Yusuke and him ever since Kurama had got his memory wiped. He only ever really spoke to Genkai and he seemed pretty frustrated. He couldn't really blame Hiei, though. Kuwabara felt equally as useless. He did wonder about this girl, though, and why they'd never heard of her.

"It still pisses me off that Koenma has all these damn secrets. We've never even heard about this girl before! How do we know she's supposed to help?" Yusuke complained, just as frustrated as the rest. He was the one that found Kurama after he lost his memory. It was a surprise to find him in his demon form, for one. It was the first time he had ever seen it but Kurama's signature youki was pretty easy to spot. Yusuke nearly got decapitated, however, and it's still a wonder they somehow managed to drag him back here. Even in his weakened state, Kurama was a force to be reckoned with.

"Am I going to be underestimated the whole time I'm here?" Shizuka announced herself, making Yusuke and Kuwabara freeze, embarrassed that they were heard talking about her. "Honestly, I wish I was in my old form…" she muttered and no one caught that but Hiei and Genkai who was standing next to her.

Hiei looked at her curiously, just as Kurama slowly made his way out of the shadows of the forest with the scent of this new person entering the temple. He watched as recognition flashed briefly across her face and her heart had begun to race, her breathing quickening ever so slightly. 'She knows him… but how? She's just a human… isn't she?' Now she was beginning to intrigue him. It also couldn't be a coincidence that Kurama didn't stay hidden. He came out to see this new person for a reason. 'There is one person… but it couldn't be her… could it?'

"Be calm, Shizuka. You can do this." Genkai encouraged her, hoping this all turned out alright. It was a good sign that Kurama had come out from hiding. Though it could just be his kitsune curiosity. She hoped it wasn't just that, though. Even in her human form, she hoped Shizuka could bring Kurama back to normal.

Shizuka nodded before slowly walking towards Kurama. He was doing the same, though his expression was guarded aside from the curious gleam in his eye. You could always trust the curiousness of a kitsune. If all else, she had hoped for that. She knew that hiding in such a vulnerable state was the better option but she knew how curiosity tended to be a fairly overpowering feeling. She stopped when he did, not wanting to scare him. They were about ten or so feet from one another. A safe distance.

"My name is Shizuka and I'm here to help you regain your memories. Is it okay if I ask you a few questions?" Shizuka spoke with a small smile, using everything she could to control her body and keep her heart rate and breathing in check. It wasn't working because Kurama commented on it instead of answering her question.

"Do I excite you? But not in a sexual way, no…" Kurama actually ventured to walk closer to her, easily towering over her in her human form. "You know me... and the fact that you are a fellow kitsune, I have to wonder…" He circled her, almost like prey and the other four were watching, surprised because this was the first time Kurama had even spoken since he lost his memories. Aside from threats for them to stay away, of course. "Your scent comforts me. But I cannot remember it. This still feels as if it is the first time I have encountered it. Yet it comforts me."

Shizuka was tempted to play dumb but it would be easy for him to sense that she was lying. She avoided the comments for now, however, and began to ask him the questions she normally did, "Do you know your name?"

"I am called Kurama."

"By them? Or did you remember it on your own?"

"I, the King of Thieves, is able to retain his own name."

"You still remember your trade, I see." Shizuka looked thoughtful and inwardly, hopeful. "Do you remember your old band mates?"

"Do you?" Kurama threw the question back at her and he stopped in front of her, sitting on the grass they stood in.

Shizuka slowly sat down, taking his action as an invitation. It pained her that he didn't remember her because this reminded her of the old days when they would discuss before and after a heist. "I'm not the one with the missing memory, now am I?" she gave a teasing smile. She could tell that he was definitely comfortable in her presence, which was a good sign. He seemed to remember some things but was it enough?

Genkai called to the other three, "Let's leave Shizuka to do her job. You three gawking at them isn't going make it happen any faster." She then turned at walked towards the dining area, where she had tea waiting.

"Damn it, Genkai. We're just curious is all! What if something happens to her while we leave?" Yusuke complained yet he got up, ready to follow Genkai.

Kuwabara was equally curious, especially with the way Kurama reacted to her. "I think she'll be fine. Remember, Kurama immediately attacked you. But he's walked up to her."

Yusuke gave an annoyed sighed, "Yeah, remind me about how one of my friends attacked me 'cause he lost his memory but he'll walk up to this new girl like he knows her and actually sits down and talks to her." This made Yusuke immediately turn fully around and follow after Genkai, irritated about the whole ordeal. He did hope she could help him, though. He knew Hiei had been pretty crushed too. He glanced up at the fire demon who seemed pretty fixed on the two in the middle of the field. "Hey, grandma, what about Hiei? He doesn't look like he's moving."

Genkai turned to look at Hiei and watched him for a moment. "Eh, he'll be fine as long as he doesn't interfere." The look in his eyes was extreme focus. She was almost certain that he had figured out everything by now. She just hoped that Shizuka could restore Kurama's memory so they could find out who did this and, more importantly, she would have her brother back.

Yusuke stopped, "What?! Why did we have to leave then?" he gestured to Kuwabara who was now walking past him.

Genkai sighed, "Would you just shut up and do as you're told? If you have this much energy, you might as well put it to good use in a training session. You too, Kuwabara."

"Well, I'm not complaining."

Yusuke groaned, "You will be…"

Kuwabara then remembered when they had first met Genkai and paused in step for a moment before continuing on in a more reluctant fashion. "Aww, man…" he definitely wasn't looking forward to it but… it would be nice getting to train.

Hiei hardly heard a word they said, focused on Kurama and Shizuka. He was fairly sure he knew who stood in front of him now. He just found it surprising that she had masked her youki and even her form was different. Unless she had a similar situation to Kurama coming to the Human World. He could never understand how such smart creatures could make such stupid mistakes. 'Ah well, they are very similar and she did love to follow him around. She took this a little too far, however.' Hiei shook his head, remembering the news of the Queen of Thieves fall not long after the King. It was said that they had even been done in by the same S.D.F member. He shook his head at the thought while still intently watching the two who he was sure were siblings.

"I remember enough. But as old as I am, I'm sure there are some things I have forgotten." Kurama replied to her, sill inspecting her thoroughly.

Shizuka was happy that he had found an interest in her but it was almost to the point that she was getting slightly uncomfortable with his staring. She remembered him mentioning her scent and she figured that aside from her kitsune scent, something else also comforted him. She flicked her long hair over her shoulder, a black rose instantly appearing. She inspected the rose, almost in wonder and awe.

"I haven't used this in years…" both Shizuka and Kurama stared at the rose before Kurama paused with a far off look in his eyes. Shizuka lowered the rose, "Remembering something else?"

Kurama refocused on her and stared into her eyes, Shizuka unblinkingly staring back, hoping he was remembering more…hopefully her.

"You have old eyes for such a young girl. How old are you, actually?"

Shizuka had to burst out in laughter, breaking his intent stare and causing him to look confused, "Was that funny?"

"Don't you know it's rude to ask a woman's age?" Shizuka sighed softly from the sudden laughter before glancing up at Hiei. This would definitely give her away. She looked back at the rose, the velvety petals so comforting. She smiled softly at it before she looked up at the waiting Kurama, "Oh, I stopped counting after a thousand. Don't we look good for our age?" she giggled a bit again before sighing, this time in disappointment. "As much as I would love to chat, shouldn't we work on getting your memories back?"

"But don't you see… Shizuka, was it? You're helping already. I do know you are of my past… but who are you? I recognize your scent, as much as the human smell might mask it for most. Your black rose is unique to one person in my life. She was very important to me. But could you possibly be…?"

There her heart and breathing went again, not to mention the tears. Shizuka blinked them away, shaking her head, "I thought they said your memory was erased? You couldn't possibly remember her…" but she was hoping that he could remember her. Maybe they only wiped his human life's memory? Maybe that's why he couldn't remember them? Oh, she could only hope.

AW: Well, that would be a good place as any to end it, hmm? This has been a roleplay before so anyone… from those years ago, who knew anything about it would know. But you lot are probably all new and this cliffhanger is hopefully catching enough. Then again, I know you might not read it since I did make an OC related to a canon character. She's my first OC with many different versions and this one is my favorite so I wanted to write about it. Plus I am still in love with the original roleplay so this is for me as much as it is for the public. I apologize for the longish AW. I hope you enjoyed the first chapter! Please review, thank you! :3
