A/n: ok ok I really gotta stop with the AUs but I know you guys liked this one. Also can anyone else quote the entire fight scene word for word or is that just me? Just me? I need to go to therapy for my addiction? Ok...

Au: Ghost! L

The girl that moved into the newly renovated taskforce building, that was now an apartment complex was pretty... shut in.

The detective could definitely see some of himself in the girl. She stayed in the darkness of her room, watching anime, making money online, lounging around in pjs and oversized hoodies, she was definitely a bit of an otaku. A literal one, not the kind that just like anime oh no, the kind that shut themselves away and don't emerge for days.

She even shared the eyebags the detective permanently had. The messiness of the hair, the casual clothing style, the tired personality.

It was like the detective was looking at his dream girl, one that was enough like him that he wouldn't be judged.

He was stuck on that floor, the one where he died in the arms of his worst enemy. It made him so ridiculously depressed to be stuck here. Alone, no one to talk to, knowing that he was killed by the man he hated so much. The problem was, no matter how bad he hurt, there was no way out. He couldn't kill himself because he was already dead, he couldn't seek help because no one could see him, he couldn't talk to any other ghosts in the building because he was stuck on that floor. His undead life was cold and miserable. He craved the acknowledgement of another person.

He craved it so much he started to screw with things around your house to get your attention. To his relief, it didn't scare you away, in fact you didn't seem to scared that your house was haunted. You were aware there'd been deaths in the building but you didn't seem to mind. In fact, you were worried for the ghost.

You could tell whoever was haunting you was in pain, he was upset and doomed to stay that way forever. When the air was particularly silent, you could even hear him quietly sobbing to himself sometimes. It actually broke your heart to know this man died so sad and has to stay that way forever. That was no way to go.

You eventually started to do research into his death. There wasn't much, just that a male aged 25, called only Ryuzaki, no last name; died of a heart attack. He was much too young for a heart attack and his autopsy said he was healthy apart from a possible iron deficiency which was why he was stupid pale before he died. But considering this used to be a police HQ, and it was during the days of Kira... you knew what really happened. He got to close to finding out the truth, and was killed to be silenced.

It was late, you'd just read about communication with ghosts. Apparently they can hear you just fine, but you can only hear them sometimes as it takes a lot of energy. Tonight was one of those nights you would lie awake listening to the echoey sobs and sniffles down the hallways. You felt so bad for the guy, murdered and now unable to communicate with anyone. Listening to him cry was getting to be too much for your fragile heart. Tonight was the night you tried to make contact. First, you wanted to see what he looked like.

You got out of bed and grabbed your phone, holding up the camera as you walked down the halls toward the source of the sobbing.

It seemed to be coming from the corner of the room, like he was curled up and hiding himself. You pointed your camera in that direction, taking a photo and tapping on your gallery icon. To your surprise, it worked. The camera managed to pick up the semi-see through apparition of a boy in a white shirt and blue jeans with messy back hair curled up in the corner with his head buried in his knees.

"Aw... Ryuzaki..." you mumbled.

The sobbing stopped, like he heard his name.

"Ryuzaki, I know you're there. If you can hear me, make something move"

It was silent, you waited in the darkness and jumped when you saw the pile of books on the bench be knocked over. He could hear you, that was good progress.

"Is there some way I can talk to you? Or see you?"

It was silent again, until you saw a whiteboard marker be picked up. You watched your mini whiteboard on the fridge.

G-I-V-E M-E Y-O-U-R H-A-N-D

"Uh... like this?" You asked, holding your hand out.

You saw the marker be dropped and felt something cold wrap around your fingers. It was kind of unsettling but you knew this ghost meant no harm. You suddenly felt what could only be described as an electric shock. You jerked your hand back in pain but when you looked up, the see through body of the boy was looking down at you.

"Wait... I think I read that. You take some of my static electricity and use it to make yourself seen?"

The boy nodded. You could see him more clearly now, his eyes were lifeless, but stained with tears. He was tall, thin and deathly pale. He was a sorry sight to see.

You reached out to try and touch him, but your hand just went right through him. He could touch you, but you couldn't touch him. He looked away in sadness when you did that, he craved another humans touch after all these years but he couldn't seem to get it. He just wanted a hug.

It'd been so long since someone had talked to him, almost 16 years he just wanted some comfort.

"Please don't cry... I can hear it sometimes and it makes me sad. I don't know what exactly happened to you, but almost every night I lie down and hear you cry, I don't know if it's because you were killed, because you miss someone, because you died sad, or have bad memories or all of those things, but you being sad makes me sad"

He looked at you in shock, tear filled shock. This time he wasn't really upset, rather... happy that someone cares. Someone makes the effort to remember him.

"If you want some company you can sleep in my bed. It's not like I'd accidentally kick you anyway, I go right through you"

In pure desperation for human contact, he nodded. Agreeing to your proposal and following you back to your room where you flopped into bed and let the ghost snuggle up to you, he was cold, but at least you could make him warm again.

You'd listened to him cry for too long, you didn't want him to be sad.

"If I ever move, you can haunt me and follow me around" you said.

You felt the coldness get closer, like he was trying to signal he was happy you'd offer that. Like he was trying to hug you.

"I know you've been here since I moved in, but just in case you never caught it. I'm (y/n)" you added.

He smiled, for once in his life... un-life... he smiled. Someone was finally acknowledging him.

A few days past of him following you around, trying to communicate with you and play the game of 'get (y/n)s attention by knocking things over'. Each night he'd come back to your bed and try and sleep next to you.

Today was a bit different though. You had a friend coming over to try and make further contact.

He heard the front door close and looked down the hall way to see what was going on.

"(Y/n) as much as I love the paranormal, inviting ghosts into your life is a bad idea"

"Ryuzaki is ok though! He's stopped crying so much since I talked to him. He wouldn't hurt me, I just need a way to talk to him"

He watched you and your friend sit at the table and put a box down in between the two of you.

"Ryuzaki, are you here?" You asked.

He floated over, sitting in mid air above the box.

"He's here" you said.

"How can you tell?" Your friend asked.

"I can see him remember"

He picked up the box, examining it and trying to figure out what it was. Your friend starring at the floating box in awe.

"Ok he's definitely here"

You took the box off him and looked up at him.

"This is a spirit box, you can use its energy to talk to us"

You switched it on, static filling the room.

"Can you say something?" You asked.

"Uh... hello?" He replied, his voice heard through the spirit box.

"Woah (y/n)! He must be super connected to you for it to be that clear!" Your friend exclaimed.

"Well I have been letting him sleep in my bed so he stops crying all night" you replied.

"Aw, that's so sweet"

You laughed at her words, knowing she'd coo at the thought of being friends with a friendly ghost.

"Is Ryuzaki actually your name?" (F/n) asked.

"No, it's my alias" he replied.

"Alias? Did you work with the police that were here?"

"Yes"

"Then why would they put an alias on an offical autopsy? Surely they'd use a real name" (f/n) questioned to you.

That was odd, why use an alias? And alias explains the lack of information on him out there too.

"Because no one ever knew my name. If I told you why you wouldn't believe me" Ryuzaki said.

"Tell us" you said.

"Well, this was a Kira taskforce. I'm L"

"But Ls still alive?"

"Oh good... that means one of my successors is doing ok..."

A successor of course. L got too close to Kira and Kira managed to catch him first.

"That makes sense, Kira was after you"

"You won't find any records on me. All my personal details were burnt or hidden. Unless you can somehow get to England and convince the owners of the orphanage to give you the papers"

"What's your real name?"

"L Lawliet"

He didn't have a reason to hide it now. He was dead after all. You did a google search for the name, but nothing came up. He really was off the grid.

"Wow, you really aren't anyone are you? You're off the grid for sure"

"I have a question" (f/n) jumped in.

It was silent, showing he was listening.

"Why have you been crying so much?"

Silence filled the room for a little longer. Like he was trying to find the words to describe such a feeling.

"Because... when I was alive I lost both my parents to child neglect and abandoned... I was severely mentally damaged growing up, and right when I think things are ok, Kira came in and ruined everything. After a while life of suffering, I died in the arms of the man I hated the most. Then for 16 years I've been trapped in this building with no one to talk to, nothing to do and no way out. No way to see the loved ones that died too... I'm more depressed than I ever was when I was alive..."

He really didn't have it good did he? A life of suffering and an afterlife of loneliness? It sounded awful.

"That's why then you finally talked to me I immediately trusted you. I just want someone to talk to..."

You and (f/n) gave each other a sad look. This poor ghost. He can't do anything to escape the pain.

"Well if it's company you want I'm always around. You can follow me wherever I go" you said.

He floated down to you and wrapped his cold arms around you. Although you were unable to hug back, you let him rest his head on your shoulder.

"You're the only one that cared enough to sacrifice everything for me... and I'm not even alive to grow with you... thank you (y/n)"

You wanted so badly to hug the boy back, and one day you knew you'd find away to, but for now words would have to do.

"I just don't want you to be so sad..." you said.

Despite him being transparent, you could see his tears soak into your shirt through his see-though body.

"Hey don't cry, I'm talking to you so you don't cry" you said I'm a soft voice.

"I'm just so happy someone can finally see me..." he replied, his voice breaking.

You looked up at (f/n) who was just watching you talk to what she saw as thin air at the end of the table with a smirk.

"What?" You asked.

"I never thought I'd see the day I ship my bestie with a ghost, but here we are"
