(( A/N : This story has SPOILERS. Like, for the whole story, since it goes from when Light takes his exams ALL THE WAY to the end. So beware!))

Prologue

I held my breath as the man, whoever he was, tried to tie my hands behind my back.

"I could kill your parents, I can kill you too!" He yelled, obviously drunk. Or high. I strained to look at his face, see him, but it was too dark. Stupid dark March evenings. All I knew was that this man killed my family, and was trying to get me, too. What did he have against our family?

"Alright, now missy, do as I-Urgh!" He suddenly collapsed, clutching his chest, like he was having a heart attack or something. I took the chance and ran, as fast as I could, away from wherever I was, some alley somewhere. I really should be home studying, instead of here.

As soon as I got to a road, I, Mayu Kaori, tripped, hit my head on something, and passed out.

*

Chapter 1: New

"Wha...what happened?" I asked. As I opened my eyes, I saw that I was in a white room, surrounded by people in white clothes. I was in a bed with white sheets, and there was a white table beside me. Too much white, too much white! I thought, freaked out. I turned as much as I could, and, after seeing a white bookshelf with white books on it, I saw red roses on the table next to me. I sighed, happy to see colour, and then looked down at the white floor, with the white carpet. I tried to sit up, tried to run, but my head thought otherwise. It spun, and the world revolved 20 times faster. The sheets moved to reveal that I was wearing a white gown.

"You hit your head, and got a concussion. You were bleeding really badly. You landed on a sharp rock," One of the white-dressed people explained. The only part of the person which didn't blend in was the face, which was obviously female, and the curly blond hair. I reached up, and felt where I hit my head. As my fingers grazed it, it stung, and I could feel a scab. "Where's my-" I was about to say family, but then I remembered the man.

"Do you remember anything that happened last night?" Another person, male, in white said.

I tried to remember, but all I could think of was how I was somewhere dark, an alley, with a scary man. "Did I leave the city I was in?" I asked.

"No, we found you a block away from here." Yet another white clothed man said.

"Take me there," I demanded, moving back my long, jet-black hair. "I'll remember if you do."

*

When we got there, it was a relief to be away from the white, white place, which I learned was a hospital.

I walked, carefully, to the closest alley, and screamed when I saw the body of a man, the man, lying in the alley.

"What!? What's wrong?!" A doctor, one of the white clothed people, asked.

I said nothing, just raised a shaking hand, to point at him. "The man...wh-who k-k-killed my family..." I sputtered.

"What!?!" A nurse screeched. A doctor ran over, and said, "He died of a heart attack. That's Matsu Otaka, that serial killer. Should report it to the police," He reported, checking the man.

*

"Must be another Kira murder," The man at the front desk of the police station sighed. "I'll put this into the files," he said, typing on a computer.

"Kira?" I asked. I'd heard that name, somewhere! "Doesn't that come from the word 'Killer'?" I asked.

"Yup," The front desk man sighed. "Look into it. Kira's all over the internet. Though, I'm surprised you don't know of him"

*

At the hotel room I rented, with things I took from my house, like money, a computer, and clothes, I googled 'Kira'. I got 176,198 results. I clicked the one labelled, Info on Kira.

Kira is the god that is killing all of the criminals all over the world was enough for me to remember.

"Oh! That person!" I exclaimed.

I owe a lot to that Kira.

*

That night, I dreamt about Kira. More like how I could thank him or her, or them.

In the morning, I knew where to start! Since I was a good detective, I could see if I could help catch Kira! Then I could meet them. Or him. Or her. All I knew is that Kira saved me.

*

"Hello, I was wondering if there was a Kira case." I asked at the police station.

"Yep," The front desk person answered.

"Can I join?" I demanded.

"I'd have to ask Ryuzaki first," The man answered, punching numbers into a phone.

"Ryuzaki? We have a girl here, wondering if she could help with the Kira case."

After a few seconds, the person at the front desk hung up and said, "Ryuzaki would like to talk to you. Go up to this room, Miss?" He said, handing me a sheet of paper.

"Call me Mayu," I answered, walking away

When I entered the room, I expected to see a man in a business suit in it. Instead, I found a laptop.

"Hello?" I asked, nervous.

"I am Ryuzaki, more commonly known as L" a disembodied voice answered.

L, L, where have I heard that before?

"Please, take a seat near the laptop so I can see you," The voice continued. It had a strange tone to it, as if it wasn't human. Hmm. So he gets to see me, but I don't get to see him? Nice.

As I sat down, I saw that the screen had a huge 'L' on it in black, with a white background.

L! I know where I heard that! That was the person who challenged Kira on TV!

Looking around for the first time, I saw someone in the stereotypical detective suit in the corner. His face was hidden. He scared me so much; I jumped and let out a squeak.

"That's Watari," L explained.

"Why am I here?" I asked.

"I need to figure out if you have any use to the Kira case. Watari," L answered. 'Watari' walked over and handed me a briefcase.

" Watari has several tests for you, to see how well you are at solving cases." L said.

The next hour was spent doing tests.

*

At the end of the last test, L said, "Okay. You are good at this. Tomorrow, come to my hotel room at 8:00 P.M. Watari will tell you where to go. You will have to wear special glasses. They will not let you see anything."

"Just in case I am Kira, you mean. Because Kira needs a face and a name to kill," I said, using my own knowledge, the fact that L won't share his name, and what he just said, to confirm what I said.

"Correct," L said.

*

The next day, a knock at my door surprised me at 7:45. P.M

"Hello?" I asked, opening my door. Before I could see who it was, glasses were forced over my eyes, and I couldn't see anything.

"Wha-what the heck!" I exclaimed.

"It's Watari," a voice whispered. Oh. Right. They think I might be Kira. But I'm not. Oh well.

"Oh," I said.

"It turns out, you're in the same hotel as Ryuzaki," Watari continued. "Please, come with me." He said, grabbing my arm. He gently led me to an elevator. We went up. Then we went to a door, and entered.

I was greeted with a chorus of male voices saying "Who's this?""Is this Miss Mayu?" and more. Where was L? "L?" I called out, and then I was cut off by a voice saying "Call me Ryuzaki." His voice was so different! But, it had to be Ls'.

"When can I take off the glasses?" I asked.

"Come with me," the voice that I think was Ryuzaki's said, then another hand grabbed my arm, and I was led to I think a bedroom or something. I was sat down on a bed, and I heard the other person sit on a chair.

"Mayu, I am Ryuzaki," The voice, Ryuzaki, said.

"Hello," I said.

"I'll test to see if you're not Kira," Ryuzaki said.

And the questioning started.

*

"Okay. You're not Kira," L said. No duh I'm not! Why would I be?

"You can take off the glasses," L continued.

I pulled off the glasses to see a raven-haired man in front of me, in a white long sleeved shirt and jeans.

"You're L-Ryuzaki?" I asked.

"Yep," he answered. He was sitting in an odd way, with his knees pulled up to his chest, his toes bare, his shoes-which were sneakers-on the ground. "I'd like a full bio, Mayu," Ryuzaki said, his dark eyes boring into me. It kind of scared me, that his eyes were black, but then I saw a shimmer of silver, and noticed they were dark grey. His hair was in an odd style, all messy, as if he just got out of bed.

"Okay," I said. "I'm Mayu Kaori. I'm 18 years old. I was born on March 5th, 1986. To write Mayu, you write the Kanji for 'True' and 'Gentleness' and for Kaori, you write the kanji for 'Perfume' and 'Weaving'."

"Very well," Ryuzaki said. "You're young, are you still in school?"

"Yep," I answered.

"Okay. Come with me," He said, walking away, not checking to see if I was following.

"Everyone," Ryuzaki said once we got in the main room, "This is Mayu Kaori. She'll be joining us to help with the Kira case. I've checked, she is not Kira. Her fake name will be Machi Kohana. Give her your real and fake name, so she'll know what to call you in public."

"I'm Soichiro Yagami, or Shijuro Asahi" said an older man.

"I'm Matsuda""Aziawa""Ukita""Moji." They all talked quickly.

Yagami? "I know a Yagami. Light. He's in my grade." I said.

"You know Light?" Soichiro asked.

"Yup," I answered.

"I'll ask if he knows you," Soichiro said.

*

Then next day, Light came up to me during English and asked, "Are you Mayu Kaori?"

"Yep," I answered. Light? Talking to me? I wonder what everyone else is thinking. Heh.

"How'd you manage to get on the investigation team?"

"Simple" I giggled. "I asked."

"Well, do you need any help? I'm an excellent detective, if I do say so myself." Light offered.

"Sure!" I agreed.

"Here's my e-mail so we can talk," He said, handing me a slip of paper. The writing was so neat! "I don't have my sound on, so you can e-mail me during class," Light continued, smiling.

"Here's mine," I said, scrawling my e-mail on a slip of paper and giving it to him, smiling as well. My writing looked like chicken scratches compared to his. I wondered if he could read it. "I never have my sound on, so you can e-mail me too."

"Okay!" Light said. He seemed very welcoming. We'd never really talked before, other than when I asked him for help with homework. Still, that was a while back. He probably didn't remember me.

Anyway, walking back to my seat, I decided not to e-mail him too soon. It would seem weird.

*

After school, I walked to my hotel so I could change for prep academy. After changing, I went on my laptop, and checked my e-mail. I had one message. It was from Light. Surprised, I opened it. It read:

Mayu:

Hey. It's Light. Have anything about Kira?

Light

After reading the e-mail, I replied:

Hey Light,

No, I have nothing about Kira yet. The team hasn't told me anything. They still don't trust me completely. Well, they know I'm not Kira, but still. I just joined. Do you know anything?

Mayu

Looking at the time, I noticed that if I didn't leave now I would be late. So I grabbed my stuff and ran for the prep academy.

*

As I got to the academy, I noticed Light was there as well. This is weird, I thought. I went up to him.

"Light!" I said to him.

"Hmm? Oh, hey Mayu!" He said, smiling again. Light seemed overly happy. I smiled.

"This is weird, isn't it?" I said. "We've just met, yet we're seeing each other everywhere!"

"I know, eh?" Light agreed. This seemed…weird. Light didn't seem like this kind of guy. I didn't know he was so overly happy.

"So, have anything about the Kira case?" I asked.

"No," He answered simply. Where'd the happy go?

"Hmm. Oh well," I said, walking to my seat.

This was really weird!

*

Back at my hotel, I reviewed my homework for the night. I wonder who got the highest score on the exam? Probably Light.

Soon, a knock at my door surprised me again.

"Hello?" I called out. Nothing happened.

"Hello?" I said again, opening my door. There was a slip of paper on the ground. It said:

Go to Ryuzaki's hotel room

"Ookay…?" I said, grabbing my stuff, and walking to the elevator.

We were all sitting around a table when Watari walked in.

"Hello, gentlemen," He said.

"Hey!" I yelled. "I'm a girl!" I crossed my arms.

"Sorry," Watari apologized.

"Mayu," Ryuzaki spoke up. "Watari has something for you," At this, Watari handed me a bracelet.

"What's this for?" I asked. The bracelet was nice, but it had this ugly square on it.

"If you press the square 2 times with force, my cell phone will ring. I'll call you back as soon as possible. I presume you have a cell phone?" Watari said.

"Yep!" I said. "Here's the number," I continued, writing it on a scrap piece of paper.

"Also, the bracelet has a tracking device, so I know where you are at all times." L spoke up.

As I took the bracelet, I put it on my right wrist. "Thank you." I said.

"No problem," L said. "Now, about the Kira case," He continued, and told me everything he knew so far.

(A.N: How was that for the first chapter? I think I did pretty well. Is Mayu Mary-sue? Please tell me. Thanks!)
