Cosmic Ripples

By: Sesshomaru's Mistress

Crossover: Sailor Moon and Death Note

Summary (full): From the first moment I saw her, I knew she was perfect. She represented the world I was striving to create- one without evil, corruption, hate, and crime. Unfortunately, I am not the only one to take such an interest in her mystery….

NOTE: I apologize for the long wait; however, I have not been feeling well. If you add school, volunteer work at the hospital, and 'work', I'm surprised I'm sane enough to be let lose in WalMart!!!! Seriously, no lie. Also, my Microsoft Word messed up there for a while and I had to figure out what was wrong with it. Anywho! Thank you to my awesome reviewers: Zipora Tsuki, Usagi Uchiha, Failisse!

Disclaimer: I own neither Sailor Moon nor Death Note. Sailor Moon was created by Naoko Takeuchi and Death Note was created by Tsugumi Ohba; however, I wish I was the creator of BOTH series. Each, in their own right, is pure genius in the making. Sailor Moon was the start of the "Anime Boom" and Death Note is a new and engaging anime I simply love.

IMPORTANT NOTE: In my fanfic, Light had yet to relinquish his hold on the Death Note and thereby forget he ever was Kira! You will find out why soon, I promise and things will get interesting! They (Light and L) will also get handcuffed…. .….….soonish…..

"Wow."

"Impressive, isn't it?" Chief Yagami questioned the small woman-child beside him. His aged and stressed features relaxed into a soft and happy smile as he watched her stare up at the large building in child-like awe. Indeed, the Kira Taskforce's 'HQ' was very impressive. What was even more impressive was the short amount of time it took for L to have it built to his specifications.

Serena could only nod a reply while she continued to stare wide-eyed and open-mouthed at the extremely tall and (surely) expensive building. After blinking away her surprise, she tilted her head to the side slightly, staring intently and curiously up at it.

"Is something the matter?" the voice of Light questioned her from her other side opposite of the one Chief Yagami was standing at.

"No…not really," tilting her head back, she turned to look for the dark haired detective. When she could find no sign of him mixed amongst the rest of the task force team, she turned her gaze towards Light, "Where did L go?"

"He has already made his way back into the building, Miss Tsukino," Matsuda replied before Light had the chance. He also successfully drew her attention away from the taller teenager, effectively preventing her from seeing Light's eyes sharpen in distaste.

"Really? But I could have sworn…" Serena trailed off and returned her gaze back upon the impressive building before her. This would be her home for however long it took to capture and stop Kira. Taking a deep breath, Serena mentally prepared herself for the fight ahead. If she planned to return to a normal life (as normal as a super heroine could get), she needed to hurry and be rid of all this nonsense that Kira had started. If only the man would have waited then he would not have had to gone through the trouble. Her Crystal would purify the whole world in a matter of only a couple of years at the most. Shaking her head of such thoughts, Serena began to make her way towards the building but a restraining hand on her wrist prevented it.

"Would you like me to show you around so you won't get lost? It's easier then one would think, especially with all the codes and passwords one has to have in order to venture into certain areas," Light's brown eyes bore into hers, silently trying to 'persuade' her into doing exactly as he suggested much like Misa usually did. Unfortunately for him, Serena was not a love struck fool for him.

"What fun would that be? Besides, L was kind enough to provide me with not only a map, but, also, a list of the codes and passwords for the area's I am allowed to enter," Serena pulled her wrist free from his grip but through him an appreciative smile nonetheless.

"Just be careful not to wonder too far, you might have trouble even with a map," Light tried to hide the irritation and disgust from his voice. Thankfully, he had much practice after having to put up with L for so long.

Serena regarded him silently as she listened to his warning. For some reason, she never felt right around Light Yagami. From the first moment she had met him, his aura had clashed with her own; however, seeing as he was but a mortal, she had shrugged it off. Now that she was Cosmos, though, her senses were even more in tuned to the happenings around her. Still, there was no amount of nega-energy, not even a trace. Shrugging it off as nothing but nerves and excessive worrying, Serena once again made her way towards the building, "I don't plan on using the map. When you get lost, you usually find something way more interesting than you would ever find when using a map. I'm sure L would be able to find me even if I were to become too lost, anyway."

"True," Light mumbled under his breath without really caring or paying attention. She was working his last nerve when it came to dismissing his presence so easily. Light Yagami is NEVER dismissed by anyone like that ever. Except in L's case. Light noticed the other members had already entered the building while he and Serena had talked outside. Regardless, he continued to stand in the same spot for a moment, staring at the doors to the Kira Investigation Head Quarters'. Several minutes passed by before he slowly made his way into the building. Immediately, he took the elevators up to the floor his suite was located on and made his way to his room. As soon as he entered, he walked over to the large balcony windows, pulled back the heavy curtains, and gazed directly into the red and yellow eyes of his Shinigami, Ryuk.

'Avoiding the Light of Hope is growing very tiresome, Light,' Ryuk whined out in his own way while gliding through the glass and moving to spread atop Light's large bed. Light, having no choice, ignored the Shinigami for the most part and let him continue to ramble on. With the security system and camera's that L had set up, it made it practically impossible for Light to communicate with Ryuk while inside of head quarters.

'This is more annoying than the time when you were being followed,' the Shinigami continued to talk to himself and the ever listening Light. His large eyes kept a close eye on the mortal he had grown to find slightly amusing but he couldn't help but to wonder how long the amusement would last.

'How much longer am I going to have to put up with this game of hide and go bye-bye Ryuk?' A hint of annoyance filtered through the normally carefree and sarcastic voice of the Shinigami but the smile never left his face. Light, now sitting in a desk chair, leaned his head back, rolling it around to ease the crick in it, and then shrugged his shoulders, pretending to be working out a lose knot in them. Ryuk, definitely not being pleased or amused with Light's answer, glided into the bed, disappearing from Light's sight.

Light stared at the spot where the Shinigami disappeared. Ever since the task force had met Serena Tsukino, Ryuk had begun to act different than ever before. The Shinigami refused to answer any questions on the subject, much like he did with everything else; however, Light did not fail to take notice of the subtle changes happening with the strange being. Ryuk rarely stayed in one place long, he always came and went and odd hours, he never joked or prodded for information like before, and even his love for human apples could not lift his moods. Now that the task force had returned from Tokyo, Light made a note to himself to corner and question the Shinigami at another time when he wasn't being watched 24/7 by the still ever diligent detective known as L.

Serena hummed to herself as she made her way back into the elevators. She had already explored the first five floors but she had a while to go before she finally made it to the top. Sadly, she was feeling stressed and, not to mention, slightly jet lagged after her flight. So, instead of continuing her own personal 'tour', she made her way up to her floor. Yes! HER floor.

Serena had been shocked to hear that she would, like the rest, be given her own floor to live on. Everything would be provided on that floor for her like it would be in any apartment. Well, considering Misa's description of her own floor, it would be more like a house instead of an apartment. Serena had tried to talk L out of offering her so much considering she felt that she would not be of much help; however, the detective would hear nothing of it.

Instead, he changed the subject to a matter that she was more than willing to discuss-cake. Yes, even after almost losing her friends and love, becoming Cosmos, and having to reorganize her whole life around for Kira, she still had a love for sweets, all sweets. So, for the rest of the plane ride and the ride to her new temporary home, Serena and L began to compare their favorite treats. One time Matsuda had to intervene before a more physical fight broke out over which ones favorite ice cream was the best.

Serena leaned her body back against the far wall of the elevator, facing the doors and allowing her to watch the numbers tick by. Closing her eyes, Serena relaxed her body and listened quietly to the 'ding' as the elevator passed each floor; however, she was surprised to find the elevator stopping before it made it to her floor. Blinking her eyes open, Serena watched as the doors slid open quietly and she was faced with L. He stood in front of the door with his finger still pushing the elevator button.

"Um, hi," Serena mumbled with a nervous smile. She laughed lightly as L continued to stare at her with that same empty look, the one that always seemed to give her a creepy feeling.

"Hello again, Miss Serena, I was wondering if you would mind a piece of chocolate éclair," L moved to stand out of the elevator's door way, sweeping an arm out and towards the small table set up with two plates of sweets set upon it.

Serena blinked rapidly a couple of times before a large smile lit up her face, "Do you really have to ask me that question, Ryuzaki?" Serena giggled as she made her way towards the table. L followed behind, smiling in his quirkish way at the sudden change in title. He always had found it amusing how she could suddenly change emotions and personality so quickly. He was quite thankful that was one thing that had not changed about her.

"I suppose not," L quickened his step so that he reached the chair before she did. Pulling it out, he let her sit down before gently scooting it towards the table. L then made his way towards the opposite side, climbing into the chair and sitting in his traditional trademark position, curled up with his arms wrapping around his knees when he was not using them.

"Would you care for some tea as well?" L pushed a already filled cup in her direction; however, Serena shook her head softly.

"No, thank you, I'm still not that big of a fan of your tea," she sent him a thankful smile and then focused her attention back on the delicious looking desert laid out before her. Clapping her hands together in front of her and rubbing them together, she took in the sight of the pastry covered in a thick layer of dark chocolate.

"Ah, yes, you always did have a preference for hot chocolate," as L stated this face, Watari walked in with a single steaming cup placed upon a silver tray. He walked over, setting the tray upon the table, before placing it in front of the Tokyo heroine and taking the extra cup of tea away with him.

"Oh, thank you, Watari!" Serena exclaimed as she picked up the porcelain cup and blew over the top of the steaming hot liquid inside of it.

"You are ever so welcome," Watari bowed lightly down towards the young woman and then made his exit from the room. L turned and watched him leave, making sure that the door was securely shut before turning back around and watching Serena closely.

Serena, oblivious to the stare, sipped softly from her cup and then replaced it on the table so her hands were free to pick up the éclair. Without a second to waste, she licked off some of the chocolate getting ready to drip from the end before taking a big bite from it. Her eyes closed in satisfaction and a soft moan of satisfaction trickled from her throat. She made sure to take her time in chewing the deliciously rich treat to make it last longer. After a few more seconds of silence, however, her gaze flickered to meet L's. Seeing him staring rather amused at her, Serena blushed heavily and laid the desert back upon the plate.

"Is something wrong?" Serena tried not to stutter as she usually was guilty of whenever caught in an embarrassing situation. L shook his head ever so slightly and, without looking, picked up a fork and proceeded to eat on his own éclair. He never took his eyes off of her nor lost that amused smirk.

"Um, where are the others?" Serena meekly questioned while picking at her desert with her own fork, trying to act nonchalant much like L was at the moment.

"They are out running a few errands before we assemble for another meeting later in the afternoon," L supplied as if she had asked for the weather report. Serena's left eye twitched lightly as she recalled how annoying that had been upon first meeting him and how funny the situations had become also. "As for the reason I invited you here, well, that is another matter entirely."

Serena's eyes shot up to meet with his and she could not hold back the look of surprise etched across her facial features. When she opened her mouth to question him upon what he meant, though, nothing came out. After a few more tries she gave up and motioned with a twist of her wrist for him to continue while she sipped on her hot chocolate.

"Since you will be joining these meetings, I feel the need to inform you of where the task force stands in catching Kira. I will also be using the time from now until the meeting to catch you up on evidence that is most crucial to this case," L sat his fork down and stood up. He walked over to a large desk positioned against the wall and picked up a large stack of files. Bringing them back over, he placed them in the middle of the table. Serena had to lean to the side in order to even catch a glimpse of L for the stack was too high and thick for her to see from her original position.

"Currently," L began between bites, "We are aware of only two Kira's; however, we believe that Kira may try to recruit others in order to draw our attention away from him. If this is the case, you're …. Disguise 'talents' will come in handy for any specific investigation to a suspect. As I have already informed you, I have originally and continually see Light Yagami as the main suspect and Misa Amane as the second Kira under Kira's command. Unfortunately, there is not enough hard evidence to convict either without a doubt. Thus, for the time being, the task force is continuing to gather more hard evidence. You shall be helping with this as well; however, you are going to have to have an alias. It is a known and proven fact, now, that Kira can kill with a name and a face-"

"Gomen…but if Light and Misa are, in fact, the Kira's wouldn't an alias be a waste of time? They already know my name and my face…"

"This is correct but we are speaking as if they are not. They both are still under heavy suspicion and are kept under surveillance," when Serena made no motion to interrupt again L continued, "Thus you will need to come up with an alias that you can use. I will have Watari make up the proper papers for concealing your identity and protecting your family. You will also be given a police ID and badge, both a manager and model business card, and press pass with proper identifications." L stopped to take another bite from his éclair and sip from his cup.

"Why would I need all that?" Serena asked. Confusion laced her voice as her brows knitted together in confusion.

"Police ID for when you will accompany the rest of the task force into certain areas of interest, manager business card and ID for when you will pose as one of Misa Amane's managers, Model card and ID for when you will pose as either a close relative or friend of Misa Amane's, and, finally, Press Pass and ID for when you will be sent undercover when other members of the taskforce cannot," L set his cup down and let his gaze once again lock onto that of Serena's, "I need to know your code name soon so that Watari may make up everything and get them to you by tomorrow."

Serena sat back in her seat slightly flabbergasted while she tried to take in everything that L had said. When Serena had not answered after a couple of minutes, L cleared his throat and brought her out of her reverie.

"Your code name, please?"

"Serenity Moon," Serena supplied as she took the last bite of her éclair, finishing it off.

L smiled softly at her decision and how fitting it would be without revealing too much, "Serenity Moon it is!"

I really wanted to continue, but I felt the need to stop here. Don't worry, though, I will not take as long to update as I did this past time.

Next time: Light takes Misa on a date and Serena is forced to tag along and babysit to make sure they don't do anything too suspicious. With Matsuda along with her, however, will she succeed or will Light be able to set up his plan for his next victim?

Please leave me some feedback as to what you thought of this chapter and I will try to have the next addition out by the end of the week.
