Chapter 1: Chess

The phone call I got was really very convenient. I was standing in the middle of my apartment living room, feeling totally helpless to complete my life goal.

My name is Amane Mizuki. I was 22 years old and I worked as an undercover agent for the Japanese police department. Actually, things had been more interesting than usual, because of Kira. The police were completely scrambling to fight the series of deaths among felons that was sweeping the nation, all at the hand of this faceless entity called Kira. Nobody knew anything about him- where he lived, how old he was, nothing. Only that he was doing an act of evil that could not be forgiven. I had been working hard recently, tailing people left and right. I also know perfectly well that I could be killed too. I had a man from America I was working with, named Ray Penbar, just drop dead one day at a subway at Kira's hand. Along with him went countless FBI officials. That was pretty much the last straw, and I resolved I would capture Kira if it was the last thing I ever did.

But it was starting to seem a bit hopeless. The only thing we knew about Kira was that he was in the Kantou region somewhere. But that was a huge area of land. It seemed impossible to find one person out of millions. Weeks of tailing and spying had come to nothing. I was starting to give up. Kira could be anybody.

And then my cell phone rang. I walked over to the coffee table where it was lying to answer it.

"Hello? Mizuki? It's Honda."

"Oh, hi. What's going on? Is there another case for me?"

"Uh, no…"

Honda was one of my coworkers. I waited for him to get to the point.

"Uh, I thought you would like to know…your sister has become deeply involved in the Kira case."

This time, I waited for him to say, "April Fools!" He didn't.

"…Honda, you're joking. Tell me you're joking."

"I'm serious; she's right alongside her boyfriend and the detective L."

I slammed my hands down on the table and screeched into the phone. "L? The L? The world's greatest detective? You're crazy! What's she doing trying to catch Kira?"

"Uh, she's not actively trying to catch Kira, really. She's mostly sticking with her new boyfriend, who is working for L."

I breathed a sigh of relief. Now that sounded like my little sister–clinging onto some boy wherever he went. If either one of us should be working for L, not to brag, but I'd be the obvious choice.

I asked him, "Who's the boyfriend?"

"His name's Yagami Light. He's definitely cut out for working under L."

Maybe he was, but I doubted that had any factor in Misa-Misa going after him. She was the type to just fall stupid at a pretty face.

"So anyway Honda, why are you telling me this?"

"See, I figured it would give you a great opportunity to really get deep into this case. If you were to impress the organization, you'd be working directly under L! Isn't that one of your biggest dreams?"

I had to fight the urge to punch the air and yell, "YES!" But I kept the cool head of an agent and asked, "Did the Chief approve this and everything?"

"Yes! He said everything is fine, as long as you can still respond to at least a few cases brought up by the police."

I smiled. "Great. I think I'll give Misa a call then and ask if I can head over to the headquarters."

"Okay. I trust you will serve well in their organization. I have to go now. Bye."

He hung up and I set the phone down. My heart raced with excitement. Finally, a chance to get serious about catching Kira! I had waited my whole life for this opportunity, and I wasn't about to let it slip through my fingers. I dialed my sister's number on my phone and waited.

"This is Amane Misa!"

"Misa? It's Mizuki."

"Oh."

There was a brief silence. I hadn't spoken to my sister in months. For siblings three years apart, we were…less than close. We were perfect opposites, her being perky, ditzy and a little self-absorbed, me being serious, analytical and a little depressed.

"I just received word that you were working under the detective L."

"Not really," she replied, "But my amazing boyfriend is! He wants to catch Kira too, and I'm just kind of helping out."

Being a nuisance is more like it, I thought, but I said, "Uh, I was wondering if you might want another agent on your team?"

"Another agent?"

"Y-Yeah. I've been wanting to work with L for a long time, and this seemed like a good opportunity."

She must have been thinking about it, because there was another silence. "Hmm…maybe you could come and meet the whole team and we could all decide if we wanna let you join!"

My heart jumped. "Yeah! Could you tell me where your headquarters is?"

"Oh! Uh, someone wants to talk to you. I'll hand you over to him real quick, 'kay?"

"Okay…"

There was a crackling as Misa handed the phone to whoever wanted to talk to me. A low, quiet voice said, "When you come here, don't give your real name. It's not safe just yet."

I was startled for a second but then I saw what he was getting at. Whoever this guy was, he suspected one of the people in the organization of being Kira. If he saw me to be a threat to his goal and he knew my name, I would be killed. I said, "I'll change my name. Thank you for warning me."

Suddenly Misa's voice spoke to me again. "What was he talking to you about?"

"Nothing," I said quickly. Then I added, "Hey, um, could you not tell the rest of the agents there my name? I'd prefer to go by…um…this nickname a couple of friends gave me…"

"You have friends?"

"Oh, shut up. Just, can you not tell them my real name?"

"Fine. I'll tell you where our headquarters are."

I grabbed a pen and notepad, wrote the address down and said, "Should I come over now, or what?"

"That should be fine. I'll see you in a bit, I guess."

"Okay, bye."

I hung up the phone. Having conversations with my sister always exhausted me. But I was too excited to be exhausted. I ran to the door, threw on my coat and walked out. For once, life was looking up.

Misa hung up her cell phone and skipped over to the huge curved desk where all of the organization's members worked. "Guess what, everyone?"

They all turned to Misa. "What is it?" asked Matsuda.

"I was just talking to my onee-san on the phone, and she wants to join the team!"

"What?" everyone asked in unison.

"We're getting a new member? That sounds great!" Aizawa said.

"I didn't even know you had a sister, Misa-Misa," Light said.

"Well, yeah…" said Misa, looking a little uncomfortable. "We're both really different, so we don't talk much. She's an undercover agent."

"What's she like?" Light asked.

"Oh, she's weird," Misa said sitting on the countertop and swinging her legs. "She's sooo serious. Like, all the time. She was always like that. Even when she was a kid, she never joked or goofed off. She's kinda depressing to be around."

"But can she put all her effort into any given task? That's a quality we look for," Ryuzaki said with a mouthful of cake.

"Are you kidding? She'll put her life on the line for something like this if she has to." Misa replied.

"She sounds like she'd be valuable," Matsuda said.

"Yeah, I guess she'd be good. She's sometimes hard to get along with, though. She's really quiet and gets ticked if you try to talk to her when she's working," Misa said.

"Well, we can use all the help we can get, and put up with any unpleasant personalities. Let's give her a chance," said Ryuzaki.

For a little while longer, they all chatted amongst themselves about the potential new addition to their organization, when, about 20 minutes later, the elevator dinged.

Out stepped a young woman with shoulder-length black hair, a pale face, and wide eyes, wearing a black, business-like dress and a trench coat. She looked very nervous but excited at the same time.

"Ah!" Misa said, jumping up. She ran over to the woman and turning to everyone, said, "Guys, this is my older sister. She wants to help find Kira!"

Yuki's POV

I stared around the huge room lined with computers that the elevator had taken me to. Cautiously, I stepped out of the elevator and looked at everyone, who gawked back at me. Then, out of nowhere, my sister skipped over to me in her wacky Goth dress, blonde pigtails, and knee-high combat boots. Seriously, her clothes did not reflect her attitude. She sang out, "Everyone this is my older sister! She wants to help find Kira!"

Relieved she hadn't slipped and told my name, I took a breath and said, "My name is Amane Rin. I would very much be honored if you would let me join your organization. I'll perform whatever tasks are necessary to get in. I just hope I can be of help." I gave a slight bow as Misa snorted and said, "Showoff…"

"Your dedication is appreciated, but there won't be any real tasks you need to perform."

The voice came from a swivel chair in the corner of the room. The chair spun around, and in it was a young man, perhaps a couple of years older than me. He was extremely pale, with dark circles under his eyes, and black hair that spiked backwards and fell in his face. He wore a white baggy sweatshirt and jeans, and no shoes. He crouched over instead of sitting normally. Overall, he looked very bizarre and eccentric, but he had this aura of power around him that I sensed as soon as I saw him. I took one look at this man and instantly knew he was L.

"All you will have to do to get in," he said, "is play a quick game."

When he spoke again I recognized his voice. He was the one who told me to change my name.

I slowly walked over to him, and asked, "You're…L, aren't you?"

He nodded. I said, "Uh…wow. I've wanted to work for you ever since I joined the police force. You're incredible."

L gave a tiny smile. "Thank you. As I said, all you will have to do to get in is…"

Suddenly, an old man stepped out of the shadows and walked over to L. He pulled out a black and white chessboard and a bag of chess pieces.

"Beat me in a game of chess."

For a minute I felt as though I might as well have just walked out right then. After all, this was the L. The man with a brain like a supercomputer. The tactical genius. I had always been pretty good at chess, but I didn't have a prayer in the world against L.

But then, I thought, this is probably a test. He's seeing if I'll just give up, or I'll accept even if I know I can't win. If that's the case…

"Sure. Let's get started."

L blinked his big panda eyes and then said, "That was the first test, Amane-san, and you passed. Now, here comes the big test. If you beat me, you can join us."

I stiffened my resolve and said, "Okay. I'll do my best."

Watari dragged a little table from the wall and set it between us. L set up the chess board. I was playing with the white pieces and he was using black. After careful consideration, I moved a knight forward. I was dimly aware that the sound of typing and clicking had ceased, that the entire room was watching the new warrior being initiated.

After my move, L sort of smirked and moved a measly little pawn forward. It was such an inconsequential move that I thought he was mocking me. I started to move my knight again to take the pawn, but I stopped myself. Wait, I told myself. That's probably exactly what he wants you to do.

I studied the board. If I were to move my knight to take the pawn, then my knight would be completely vulnerable to an attack from his rook. I mulled it over and decided to move a pawn.

L looked genuinely surprised. He studied me very hard and said, "I underestimated you a bit. Now, I won't go so easy on you."

After that, he went anything but easy on me. I had played against some very good players before, but nobody half as good as L. I was getting a monstrous headache from trying to figure out each and every move he tried to make. About an hour had passed, and by then I had claimed three of L's pieces, while he had most of my pieces and my king was cornered.

"Checkmate," he said quietly.

I stared down at the board. I could see that there was no way I could win this. I tipped over my king and surrendered.

L sat back in his chair and smiled. "Looks like I win."

I just nodded. I wasn't surprised, really. But I was crushed. My hope of working with L's organization to catch Kira had gone down the drain. L said, "You realize, of course, the results of your test?"

I nodded again. "I guess I'm not cut out to work here. I know when I'm beaten. Thank you for giving me the chance. I'll be going now."
I stood up and was about to bow to everyone when L got out of his chair, walked up to me, and stuck out his hand. "Welcome to our organization. I'm sure you will be a valuable member."

My mind reeled with confusion. "…Huh?" I said brilliantly. L grinned widely and said, "You just passed three tests I designed for you while I waited for you to arrive. One: to stand up to even the most impossible of challenges. Two: to display exceptional tactical abilities, as well as thinking like your opponent. And finally, three: to know when to surrender. You performed these abilities beautifully, and I am confident you will be an asset."

Stunned, I stared into L's black, abyss-like eyes, searching for some trace of a joke. There was none.

I had made it in. I was working for L.
