A new day. A new death. That's what Day, M, C, and the rest of the Investigation team had gotten used to. Kira wasn't giving them an inch, and the investigation was going extremely slow, though it had only been about a month. There was a pretty large team, so they subsequently moved to the building built by the previous L for the investigation so the ten of them could work in close proximity without being claustrophobic. Though they didn't like to think about it as to wait everyday for someone to die, but at this point, it was the only thing they could do. The task force consisted of Day, C, M, Touta Matsuda and his daughter, Chihiro, Near, Far, Shuichi Aizawa, and Dark and her brother, Kenji.

Kenji was Dark's younger twin brother; his brown hair flipped lazily as hers did, his hazel eyes gazed nonchalantly at the computer screen in front of him as numerous faces appeared, each branded the words "Death By Kira." Though this sight may have un-eased many a person, Kenji didn't fall under that category; he was unfazed as death after death appeared in front of him; life after life taken away. He yawned and rolled back in his chair, the lights shining off of his thin glasses. His sister sat at the seat next to him, the tiled floor surrounding her covered in files on the case.

"Ugh…!" Dark moaned, throwing her head back in exasperation. "We're getting nowhere with this! Kira won't give us anything, and we're basically screwed over otherwise! People just keep dying and dying, and we're not doing anything to stop it! I mean, I know it's not like we can… But it frustrates me that all this work is going to nothing!"

The nearly identical boy next to her stood and took his sister by the hand, standing the stressed girl up. "Dark-chan… Maybe you should get out… We've been in here for about twenty hours now… A break wouldn't be so bad…" He looked up to Day. "Is that okay…?"

The blank eyed, white haired girl looked back and forth a few times between the boy and his sister, and then got up. Without looking back, she stated; "Fresh air may do her some good. You can take a walk, you two. But I will be joining you."

The two pairs of hazel eyes looked at her curiously, but both nodded. Day quickly took Dark's hand and led her to the doors that lead to the elevator that would take them outside while Kenji quickly followed.

A look of shock covered both pure, tan faces as the other girl's pale lips spoke those seven words as they arrived outside. Kenji, though shocked, kept his cool, allowing his thoughts to be locked away by his hard stare. Dark's eyes, on the other hand, were filled with anger, fear, sadness, but mostly betrayal.

~DEATH NOTE~

A small girl sat on the side of the street in Tokyo, Japan. Her light brown hair was knotted, and her face was dirty and void of any hope. Mitsuko, she called herself. The seven year old knew that wasn't her name, but at this point, she was too scared to talk to anyone, or to open her real self to anyone. So that's who she was. Besides, the people around here didn't care about her. She didn't matter to society.

Her day consisted of going into a few shops, to act as if nothing was wrong, maybe get a water or apple from the group of college students who were always in the stores at this time and knew her… Knew she couldn't afford anything on her own. She appreciated them; they were kind people, unlike the others who would just stare at her. Stare and whisper about her tattered clothing and her dirty face. Those were the people that made Mitsuko cry. And that's how it was, day after day, every day.

That is, until early one Sunday morning. The streets were empty as they usually were at this time; people who went to work were gone to their respective jobs, families were at religious services, and the market was pretty much closed. No one was around. Except, of course, for Mitsuko. She sat on the curb outside a sushi bar as always; just a normal day for her, always being alone like that day… That is, until she saw the man who had just walked across the street and was now approaching her. He was tall, and obviously older, maybe in his forties. The man's long black hair just barely covered his eyes, but the small girl could tell he was youthful; his face, his attitude, and his soul. She stood, but instead of backing away as she would any other stranger, she just kept still. Without knowing him, she trusted the man.

When he reached her, he gave her a smile and held out his hand. "Hello… You seem alone out here. What's wrong…?" Something about the caring tone of his voice allowed her to take his hand and shake it. She knew he wouldn't do anything to hurt her. His voice had a vague British accent to it, but it wasn't native. It was as if he'd lived there for a while and the tone had caught on; she could tell he wasn't from Britain because he spoke and looked Japanese. Maybe he didn't know she spoke English as well; for a poor seven year old, Mitsuko was quite smart.

"Y-yeah... Thanks for noticing. I… I live here." As she spoke, the man's eyes grew sadder and more worried. "I have no parents… No one really cares. So this is life for me, I guess. My name's M-Mitsuko." She said, obviously lying.

The man gave her a curious look as she began to speak again, instead attempting an easier tongue; English. "Is this easier for you?" The man's face filled with shock as he heard how easily she transitioned between the two languages, and nodded. "What can I call you?"

"Mitsuko… Is that really your name?"

She looked to the ground, knowing this man could see through her lies. "No… It's just… No one's really cared enough to ask… It didn't matter to them. My name is Dark."

He smiled. "Okay Dark… You can call me Watari."

"Watari?" He noticed the confused look on her face.

"It's merely a codename… Used for precaution. So Dark… How'd you like to come live with many people…? It's quite a far way away from here… I'm in charge over there. There are a lot of kids over there… One in particular I'd like you to meet."

"Sure…" She looked up. "Not like there's anything I'd be leaving here. So how far are we talking…? Like, other side of town, next prefecture…?"

"Actually… England."

~Wammy's House~

They had arrived with no trouble, and Watari led the girl to large doors which lead to an equally large room filled with kids. He walked her across the room to a girl a few years younger than Dark, maybe about four, with dark eyes and pure white hair.

"Day?" he spoke. The girl looked up to him in response, his talk preoccupying her from the piles of toys she had been playing with. "This is Dark. I'm sure you'll be great friends."

~DEATH NOTE~

"You suspect us of being Kira, Day?! What the hell is that about?! I've known you since you were four! Matsuda… Watari took me in when I was poor and alone on the streets… You were always my only friend… How could you think that?!" Dark screamed, her voice cracking with tears.

"I'm sorry Dark… I just—"

"You knew Kenji even longer! He's known you your entire life! What would possess you so much to accuse us of such a horrendous thing?!" she continued to yell. "You know what? I'm leaving! We're going home…!" Dark began to storm off, dragging her brother by his sleeve.

Kenji, being the level-headed one in the situation, called back to Day as he was pulled down the street. "We'll be back tomorrow… She'll be fine… Don't worry." That's all he could fit in as the other girl nodded and walked back into the large building that was headquarters.

Dark kept angry up until the point where they walked into their home. At that moment, her face became somewhat calm, but mostly smug. "Heh… So she suspects us. How upsetting."

Her brother laughed before he spoke. "Oh well… It doesn't matter now. Delilah River… Your fate's been sealed." He said, his eyes glowing a deathly red just as his sister's did.

"Just keep cool… Just as dad would've."

"Of course… Go get your laptop, nii-chan…" he spoke calmly. Dark stood and picked up the folded black and silver macbook off the counter in the kitchen and sat on the carpeted floor of the living room next to her brother.

She lifted back the top to the computer, revealing an already open internet window. "Ready?" she said. The other boy nodded. "Makoto Yukiko." She began, and turned the screen to her twin, showing him the photo of the woman on the page.

"Right."

~D, C, M, W, N, F~

"You told them, didn't you?" M began as Day walked back into the room without Kenji or Dark. She nodded as a simple response. "Bake…" he muttered. The look on his face was depleted of all emotion except for shame. "Now neither of them is going to come back."

"No… I know Kenji… He'll come back… And drag Dark by her collar." Day replied, sitting back in her chair.

"Watari?" Far suddenly spoke. Matsuda stood up from his place, leaving the computers he had previously been working with.

"Yes F?"

"Please connect the files you've been working with onto my computer. I believe I've got it."

At that point, everyone turned in the room toward Far, with faces filled with shock and confusion. "You have been awfully quiet…" Near finally spoke after a long quiet spell. "What've you come up with, Far?"

"What've I come up with? I've come up with substantial evidence… And a conclusion." She began, standing up, walking about the room peering at everyone's screens as she passed by. "After reviewing time schedules of killed criminals, along with note and hints given to us by Kira himself…" her dark eyes darted to every member of the task force that sat around her with a deathly serious glare. "I've determined that Kira… Is among us. Right now, possibly." She stepped carefully to the front of the room. "Though I doubt it. I understand that you vaguely suspect Dark and Kenji… But I know… Almost for a fact that the two of them are Kira. And this is due to cameras I've placed in their home a while back with Watari. Though the cameras have been removed…" she continued, pacing back and forth. "They have revealed something vast to me that allow me to suspect the pair at a maximum." She motioned to the screens behind her. "Watari, if you'd please."

"Of course." He typed a quick key code into his computer, and a still frame came up on the large screen. It was of the boy-esqe twins asleep, lying in bed; Dark in a white tank top which was covered by her white button up shirt that was just opened at the top, and Kenji only in a pair of sweatpants.

"What's the point of that?" Aizawa spoke, agitation showing in his voice at the seemingly pointless clue.

"At first glance…" Far began again, the motivation in her voice growing with each word. "This may seem like a normal sight… Two siblings, asleep in bed near, I'd guess, three in the morning. But if we zoom in quite a bit…" At that point, Watari zoomed into both Dark and Kenji's upper left shoulder blades. "You see the black mark? Both of them have it."

And as she said, a small black symbol, similar to a tattoo, was on each of their bodies.

"Okay…" Aizawa continued. "So what is that? It looks so familiar, but I can't place my finger on it…"

"Look it up under symbols in the files, then."

Day turned back to her computer and opened old case information from her hard drive. Far, who sat next to her, was doing the same, but looking for pop culture symbols that could be used in gangs and other allegiances.

"What are you trying to say?" Near spoke, his words speaking for the rest of the task force as one.

"I've got it— "Day said, cutting off her own voice in shock as her grey eyes widened. "No way…"

"Yes." Far stated. "It's a symbol that, in the previous investigation, was known as the upsilon alpha. Though it only first appeared after Light Yagami's death, it's still considered a large part of the case. The letters upsilon and alpha are both Greek, corresponding to the Latin letters Y and A."

"It does look like a Y and A connected… But what does it mean?" Chihiro inquired, appearing like her father in the first investigation, slowly getting into it more and more.

"I was about to say that. The upsilon alpha was a symbol of a pair… A family. It was created by Misa Amane, the second Kira, before her suicide in 2011. The letters were meant to stand for her and her lover's last names together… Yagami and Amane. She registered it as their family crest before she killed herself, meaning that Dark and Kenji have been lying to us this entire time. They've known who their family was this whole time. They are Misa and Light's children… The spawn of Kira himself."

Shocked faces spread around the room. "W-why would they l-lie to us like that though?!" Aizawa stammered, he easily being the one most affected by this, seeing as he knew Light and Misa firsthand.

"That's exactly my point. If they told us their family history, they knew they'd be easily suspected from that moment on; if they really have nothing to hide, then they would have told us. I want to get more evidence on the two… As much as I can. I'm confident I'm correct in this. And if I am, that means we can stop them quickly… All we need is evidence."

"Exactly." Watari said, shutting the computer and sliding it into his case.

"Tomorrow, we come back and we begin… Begin the end of Kira's reign, once and for all."
