But was it so easy?

All she needed to do was write a name in the Death Note, and the Shinigami attached to it would take care of the rest.

But how trustworthy was the Shinigami?

Author's note:

If you are looking for a canon focused fic, this is not it. I have tweaked the Death Note rules to fit this story. Please be lenient with the Japanese dialogue. It's been many years since I studied and practised properly, but I was not passing up an opportunity to use it in a story.

Ryuk is based on the Netflix live action, voiced by Willem Dafoe.

She scoffed at the office workers leaving yet another unnecessary mess. The bin was in the fucking direction they just walked to! She hoped no one ever visited their house if this is the state they left their public area in.

The news on the T.V. overhead caught her eye. She continued wiping down the table while reading the subtitles.

Do politicians even care? Do people in power, even care?

The world seemed to be getting worse and no one who could make an actual impact was doing anything about it.

She left for the next clean up location.

Aren't politicians supposed to serve the people? Aren't they supposed to be making lives better? Improving their communities and country?

Why are they, of all job professions, able to get off scott free without ever doing jack shit to help? They make people's lives worse, not better. All the policies they place that don't affect them, that greatly destroy other people's lives.

Fuck 'em. They're the ones that deserve to die.

Fucking great. In her anger, she went too heavy on the disinfectant. She needed to top up before the next place. Dammit! She was going to loose so much time going to the storage room.

Her calves burned and she hurried to storage. The lock needed to be replaced so the keys weren't working for her until she slowed down, of course. When she finally unlocked the door, she stormed in, bee-lining it directly to the chemicals.

On the way back, she noticed something out of place. Ugh! Some idiot left their note book in here. She picked it up.

It was bound in black leather. Had that kind of old, yellow parchment paper too. Who the hell would leave this at work? There was no name that she saw. But on the cover in large print it read: "Death Note." Okay. She'll take it to lost and found anyway.

A few steps down the hall she heard tumbling of something in the room.

"Just ignore it. It can be someone else's problem."

She took another step.

...

Fuck!

She begrudgingly unlocked the storage room again. Scouring the place to find what the hell it was that fell.

"Are you kidding me?" She grumbled. "I wasn't anywhere near that side of the room!"

It wasn't a difficult mess. Just pick it up and put them back. We're only half way through the week. Just get it done.

Krchhnk!

Her back straightened. She looked around the room. She didn't hear anyone else come through the door.

"...Is someone in here?"

...Silence.

She didn't have time for this. She was behind enough as it was. The others will be having break without her. She had to hurry.

Dnmp!

Her head whipped around. In the aisle there was an apple with a massive bite taken out of it.

"Oi!" How dare they? "Who the hell do you think you are?" She stormed up to where the apple lay. "Pick up your shit you little-"

But as she turned the corner to the other side of the shelving, she found it wasn't little. It was huge. She had to raise her head to meet it's eye. It's horrifying glowing red eyes.

But that wasn't the worst. It's grin was wide and sickening. She didn't know where to look from the eyes, to the teeth or to the porcupine-like quills sticking up out of it's shoulders. She just stood there, frozen from fear.

"Shall we begin, Keeper?"

Not frozen anymore. The growl in it's tone spurred her escape. Well, she might have escaped, if she didn't run back to where the mess was. Which was in the opposite direction for the door.

She ran into one of the back aisles. Squatting so it hopefully doesn't see her as easily. What was she going to do? Where was she going to run?

It's cackle echoed through the room. She covered her mouth with her shaking hand so it wouldn't hear her whimpers.

The room went silent. She heard nothing. She stayed in place but tried to crane her head around the corner. It wasn't coming for her.

"I'm fucking high." She reasoned with herself out loud. "I'm just tripping. I must have used too much product back there. It's just a trip. Or dreaming or some shit."

"Oh yes, a dream, I like that..."

She yelped and fell back against the shelf. Knocking a few things off.

The creature had sauntered it's way over to her; It's towering figure somehow went unnoticed. It's voice chilling her down her spine.

"Dreams are places you can have fun, right?"

Fun?

She had no idea why she did it. But with it's humanoid shape, her eyes darted between it's legs. This was not the time to think about the nature of her dreams.

"It's all in your mind so, why not enjoy it?"

Her eyes flicked back to it's glowing eyes. "...What are you? What do you want?"

It descended to her level. Smiling at her with sharp teeth. She could see now, up close, that his black shirt had ruffled fur around the collar and shoulders. And those quills shot straight out of him. She did not want to test the sharpness of them.

"My name is Ryuk. I'm your new Shinigami and you are the new Keeper of my Death Note."

"...The fucking book?"

"That's right. Write a name, and I'll take care of the rest." He stood. And it seemed like it took forever with his height. "We'll be working very closely with each other here on out, Keeper."

He retreated back behind the shelves. His cackle seeping into every uncomfortable crevice within her.

She pushed herself to see him go. Where he came from. But as she turned to look around in the aisle, he was already gone.

She wasn't thrown off enough to leave early, but the others noticed something was off about her on break.

She shrugged them off. Not knowing how to explain it. "Oh, you know, the state of the world."

She sat at the table with the Death Note in front of her. That thing said he was a Shinigami, a Death God? What did he mean by writing a name?

Her thumb ruffled through the pages of the notebook before opening it properly. A few pages in, it had the heading: "How to Use."

She hunched forward, reading the rules before her.

Krchhnk!

Her body tensed. That sound came from her bedroom.

Death Note in hand, she hesitantly walked towards her room. Upon opening the door, the creature from before, Ryuk, was sitting on her bed, having just begun eating an apple.

He wore all black. It contrasted with his corpse-like white skin. There were chains and links around his wrists and belt. The apple looked so small held between his thick, long fingers.

"Nice place, Keeper. All by yourself?" He took another bite.

Keeper found that she couldn't look away from his hands. The chains wrapped around his wrists. Was it a simple accessory, or convenient weapon?

Could he, with precise movement, unwrap them from himself, and use them to restrain her? Drag her off somewhere or tie her up, holding her captive in her own home?

Would he tie her up unclothed?

The pattern of the chains leaving indentations on her skin. Tight and restrictive. Leaving his long claws free to caress her as gently as he did the apple?

The apple he carelessly threw to the ground earlier. Keeper snapped out of the absurd thought.

"...Make sure you put it in the bin this time." She instructed him.

His lips peeled back revealing sharp teeth as he mockingly laughed at her. "Found some courage, have we? Giving me rules, Keeper?

She raises the Death Note in her hand. "Seems like there's already some of those. What's one more?"

"Hmm, so you've read them?"

"Tried to. You interrupted me."

Ryuk took another bite of the apple as he assessed the braver approach his Keeper was giving him. She watched silently as almost half the apple was gone now.

"So, what exactly is your goal here?"

He raised his, lack of eyebrows, questioning her question. Taking another bite.

"I write someone's name and you kill them for me?"

"That's about it."

"What if I spell the name wrong?"

"It doesn't work. Spell it wrong four times and now that person is unaffected by the Death Note. So don't mess it up. You'll also need to picture the person's face as you write their name down. It avoids killing the wrong person with the same name." Krchhnk!

Keeper looked down at the book in her hand. "Some thorough rules."

"Indeed." He replied after finishing his mouthful.

"So what's the catch?"

"Come again?"

"Why do I have this book that can kill people, and why do you want me to use it? What are the cons of using the Death Note?"

He sighed, leaning his elbows on his knees. "Scared, Keeper? You want little things like rules dictating your life forever?" He tossed his core towards her.

Her heart went rabid. Beating in her chest at the disrespect in her own home.

"Pick it up!" She demanded, pointing at the core with the Death Note hand.

Ryuk sits up. Unexpecting of her outburst.

"Don't you dare come in here disrespecting my space! Don't you dare try belittling me with all your yokai bullshit! I am not playing your fucking games!" She takes a step closer, and repeats with a snarl. "Pick it up."

Ryuk slowly, rises from the bed. Completely perplexed at how different she was acting to mere hours, seconds ago.

"Bin's over there." She points. Glaring at him the entire time.

He follows her instruction, but in no hurry. His movements were slow and drawn out. He looked to her as he had arrived at the bin. His arm outstretched, he dropped the core into the bin. The pair keeping eye contact the entire time.

Keeper released a heated sigh. "Query for you: Ryuk, Shinigami. They sound Japanese. You don't."

"Motto ii? (Better?)"

"...Sukoushi. (...A little.)"

His eyes light up with a light chuckle. "Hanasemasuyo! Doko? (You can speak! Where did you learn?)

"Koukou to daigaku de. (High school and uni.)"

He cackles. "Sounanda. (I see.) Shinigami can speak the language of their Keeper's ethnicity." He steps closer to her. "If you were Japanese, I'd speak Japanese. If you were French, I'd speak French."

She brought the conversation back to her last question. "Is there anything bad that would happen to me for using the Death Note?"

"I wouldn't do anything as stupid as putting your name on the cover, if I were you. But, not really. Unless I decided I didn't like you, however."

She arches an eyebrow. "What would I have to do to keep you liking me?"

Ryuk squinted in curiosity at her new tone. Much softer. Inviting even. "Write a name, think of their face." He leaned in for a sinister whisper. "I'll do the rest."

Ryuk sent shivers up Keepers spine and tingles down to her groin. Uh oh.

He straightened up. "I'll let you read your precious rules a little longer. I'll be back."

She stayed in place as he wandered off somewhere. She didn't bother trying to see how he disappears.

...He was very tall. Very menacing.

The quills on his shoulders where a challenge in her mind. Keeper was trying to think around them.

They'd shred her bed too much. Cowgirl would be out of the question. But his arms were long enough. He could easily give her a good reach around in doggy.

She held the Death Note in both hands. If he's a Death God, what kind of leather was this made out of?

There was some reading to be done.

The radio trailed on and on about the unending devastation in it's news report. New bills getting closer to being approved which were not actually going to improve anything.

While hooking the vacuum cleaner up, Keeper felt a presence over her shoulder.

"That's a good name they have." Ryuk whispered in her ear. She could feel the fur on his collar. "Remember to take note of their face."

How could a growl be gentle? How could such a rough voice be inviting? He was too close.

"Excuse me, I have work to do." Keeper turned the vacuum cleaner on. Blocking out the radio and Ryuk.

Ryuk had been following her to work. So far it seemed like the others didn't see him. He was connected to the Death Note. So she left it in her "secret" sleeve in her backpack. Safe in her locker. He did however, make the rest of the week, difficult.

As she woke up that unrushed Saturday morning, she took her time pondering the Death Note over her breakfast tea. She didn't ponder for very long. Throwing the tea bag away, Keeper took note of all the apple cores in her bin. Where the hell was he getting them all?

The weather was pleasant. And she had a plan in mind.

"Thank you." Keeper said to the cashier as they passed her her bag of apples.

There was a nice park nearby. She'll have a rest and eat before toddling home.

With a park bench in sight, Keeper opened her bag and just as planned, Ryuk's thick fingers dived right in.

"Why, Keeper, you shouldn't have." Krchhnk!

Keeper smirked up at him. "I was wondering, Ryuk. How visible are Shinigami?"

He looks down at her with a squint. "Why?"

She makes a frown and shrugs. "It's just that no one else seemed to notice you popping in at work."

"Hmph! Humans cannot see Shinigami without a Death Note. And they need the Death Note of that Shinigami. Of course they don't see me." Krchhnk!

"Ah, but they would see a floating apple right now, won't they?"

Ryuk stopped dead in his tracks....Whoops.

Keeper continued on and waited for him at a park bench. She brought herself out an apple, but tied the bag preventing Ryuk from accessing them. Leaving it to her side.

"Why do you like apples so much?" Chshnk.

Ryuk hesitated a moment. There was something in the way she did that. How her lips lingered on the apple skin...

He looked her up and down. "...They're not as juicy in the Shinigami realm."

"Sokka... Tabetaidesuka. (I see... Want some?)"

Keeper was resting her elbow in her palm. The hand holding the apple dangling over her shoulder. She turned her head from him for another bite on the apple. Her eyes however, glanced his way.

Chshnk.

He could hear it's juices with her little bites. She dangled the apple over her shoulder once more.

...He didn't need the apple that bad...

He didn't!

While he made up his mind, Keeper took notice of someone playing fetch with their dog aways on the grass. After a few throws of fetch, it was time for another bite.

She was beaten to the punch. Ryuk's arm came around her. Reaching to her side for his bag of treasures. His other hand he placed on hers, as he ate the apple from her hand in one giant mouthful. Core and all.

There was wet crunching behind his lips. Those sharp teeth shredding the fruit with no effort. Ryuk looked at her with annoyance as he chewed.

Without retreating from his gaze, Keeper reached for the bag, but found Ryuk's hand first. She grabbed the bag with his hand still under hers and placed it in her lap. Ryuk shifted his hand as she opened the bag. He let it fall, grazing her thigh. She pulled out another apple. Repeating the process and draping it over her shoulder. It hovered between the two.

"Donna ge--mu o shiteimasuka. (What kind of game are you playing?)" Ryuk asked, feeling the warmth of her living flesh under his thumb.

Keeper batted her eyes with a puzzled expression. "Tabeteiru. (Eating.)" She replied simply. With such softness and innocence as to never imply anything otherwise.

His eyes narrowed at her, unconvinced. But Ryuk did, of course, lean in for his next bite.

As did Keeper.

Strategically joining him on the apple. The pair cheek to cheek as they ate.

Ryuk had left her after all the apples were gone.

She had such a spring in her step after her plan proved to be a success. She had him literally eating out of her palm of her hand! Ha ha!

One of the shops on the way home had a sign saying discounts on note pads. Keeper stopped in her tracks, and went inside.

She had been looking up certain people while on her breaks at work since Ryuk's first visit. In her new note pad, one who's pages could be easily ripped out (and then burned), She began practising her writing. Of thinking of their faces as she did.

The Death Note lay within arm's reach on the table. After a few names had been written, she opened it up.

Maybe she should make sure she reads over the rules before she puts anything in here...

They're so fucking rude!

Who purposefully makes a mess right in front of the fucking cleaners?! What kind of self absorbed adult behaves that way?

Keeper and the other cleaner muttered under their breath about the other staff in the building while they cleaned.

A familiar presence returned over her shoulder. "Namae o kaku. (Write their name)."

"Shizukani. (Quiet.)" Keeper tried to say under her breath.

"Nagaijikan hitobito o kizutsukeru. (They've hurt people long enough.)"

"Shizuka. (Shut up.)"

"Minasan wa genki ni narimasu. (Everyone will be better for it)."

"Urusai! (Noisy!)" She yelled over her shoulder. Remembering too late the other cleaner working just the other side of her. "Gomen- sorry. Excuse me." Keeper took the rubbish and rushed away. Embarrassingly leaving them with the rest.

Ryuk's taunting laughter echoed with her down the hall.

The hot water poured over her head. She just let it rain down on her, drumming out her thoughts.

She needed to let it go. She was home now. It was pay day tonight. It's fine.

Keeper was in the shower longer than necessary, however, drowning out the shittiness of the day could be considered necessary.

She wrapped her towel around her, dragging her feet onto the bedroom carpet after leaving the en suite.

"You're writing them-"

"Fuck!"

"-in the wrong book."

When the hell did he get here!?

Keeper leaned, panting in the door way from Ryuk's stupid jump scare.

He looked at her. Eyebrow arched, thinking her reaction was a little over board. He held her new note pad in his hand.

He raised it. "What is the point of this?"

"I'm still thinking." Keeper gasped.

"You want to leave evidence of the names?"

"No, that's why I'm going to burn the pages when I'm done. And I'm still thinking about the cause of death, anyway."

"You don't need to worry about that."

"Usotsuki! (Liar!) Shinigami only choose a cause of death if the Keeper doesn't write one. You've been lying to me from the start! You're nothing but some murder hobo yokai but you can't kill unless I give you a name."

Ryuk stormed over to her. Eyes nothing but red. "And you're taking your sweet time with it, too!" He yells.

"I'm fucking working on it! As the Keeper it's my decision to use the Death Note however I see fit. I could only write one name. I could write thousands. And it's my choice! I don't need you following me around at work."

His mouth goes wide, flashing his teeth. "What do you suppose happened to my previous Keeper? I don't need you either. You asked if anything bad could happen to you." Ryuk stood over her, his head standing just above hers. "And I said it depended on if I liked you."

"Oh, I'm just supposed to roll over and be your little pawn, am I? Well, guess what, that's not how this is gonna work. I will write in the Death Note when I am good and ready. With both a name and a cause of death. So you can either only come back here to tell me you've done your job or," Keeper dropped her towel. "Do something with this!"
