Title: Girl with a Lock, Detective with a Key.

Disclaimer: Saika is my character, anything else to do with Death Note is not mine.

A/N: This is my first Death Note fic, I'm totally in love with L as you can see, so I put him with an OC, I don't mind L and Raito together... but I'm not up for writing yaoi..yet. Heheh, please review!

Sin wasn't a jolly Shinigami when it comes to staring at completely nothing in the Realm of the Shinigami. He hated apples too. He remembered when Ryuk the annoying God kept waving rotten looking apples in his face.

Sin was a rookie shinigami... and he still had some of his organs. He had a heart of rotten flesh that was still pumping in a very disturbing (well to a human it would be) way... he still had muscles that looked as if they had melted around his skeleton like form. His face was slowly forming as a cracked mask of white with black slits for his eyes.

He had large bat like wings; one however was ripped of its skin, so it looked as if he had one black healthy (if one could call anything of a shinigami healthy) large wing while the other was just a skeleton.

Not many shinigami had something to do. Many just slumber, and Sin would just watch them every few minutes. But it wasn't until he decided to peek into the Human World, where almost everything changed for him. What could a shinigami possibly see in an eighteen year old student with long warm chestnut hair and chocolate brown eyes?

He certainly was no pervert... yet in a way he was just interested in watching her doing her daily routine of sleeping, waking up, eating breakfast, go to Uni, return home, shower, study, eat dinner, study and then sleep. Veeery interesting...

Perhaps it was her smile that got him interested? Sin knew his limits of interest however. He had no limit to hating something, but to being interested in something or even someone, he knew his barrier well. She was human. He was a death god.

An unlikely combination.

He wouldn't have minded just sitting on his rock, watching the girl in the human world for the rest of his long life... however she will die of old age if not any freak accident installed for her. Sometimes he'd wonder what she'd do if she saw him? Probably die of a heart attack. She was way too innocent to be dealing with deathly creatures. But he didn't really have time to make any proper choice, when she was being chased by some drunk bastard.

So what did he do? He dropped it; his Death Note. He spread his wings (the crap wing and the good wing; it's a wonder how he can fly without losing balance) and swooped down, as if racing the black book itself.

As he hoped and planned; it fell right before the drunk's step.

"Eh, whazzis?" he said in a slur. "Jus' dropped like lat!" he made a grin and picked it up, as the girl backed to the edge of the pier. "MONSTEEEER! AAAAARGH!"

Sin growled and swooped down to his level. He flew straight through him, scaring the drunk out of his pants. The drunk stumbled back and fell right off the edge of the pier and into the dark water (it's night by the way). "HELP! I CAN'T SWIM!" he gurgled and sank after a minute of struggling. Bubbles emerged from the depths of the water and then nothing.

The chestnut haired girl breathed shakily as she edged to the water. Nothing but the black abyss of the liquid. She swallowed and glanced at the 'innocent' black book lying at the edge, almost tipping to the surface of the water. She picked it up and flipped through the pages. Nothing but lined pages. She frowned and looked at the cover. There was a silver 'S' (in the same font as the font used for 'L'),

"That is there to make it clear to the others that this book is mine...was mine."

"Others...?" echoed the girl, not looking where the voice came from.

"Other shinigami."

"Shini—what?" the girl whirled around and gasped, dropping the book.

"My name is Sin. And yours... is Manami Saika, isn't it?"

That was their first meeting. Sin would never forget her horrified look of seeing a 'monster' floating before her and well... who would blame her?

It wasn't so bad to communicate with Saika as Sin thought. He knew her as 'Sai' and she'd occasionally point out that their names both start with 'S' and it was coincidental about the letter 'S' on the cover of the Death Note. She was still in shock but it wasn't long til she had conversations with him as if he too were human. Slightly, Sin would find that insulting. But with Sai, he was all too happy talking with her, having her seeing him instead of him seeing her secretly from the other Realm.

She took in the rules of the Death Note into depth and because of this, she figured how this rumoured 'Kira' was killing criminals around the world and mainly in Japan. 'It looks likes I'll be seeing Ryuk sooner than I thought', Sin thought.

There were many coincidences with Sai that it looked too suspicious for them to be coincidences. For instance, Manami Saika was the world's famous detective's girlfriend.

A/N: Well this is it for now, I hope you liked it so far! Please Please review. I found out shocking news about L's details; age, weight, name and all. I won't tell them here if you don't want to but just saying it was a great shock it almost put me off my story here v.v"
