Welcome to my first DRRR! story on Fanfiction. Just reminding you, this is in fact post-anime (considering I have little knowledge of the manga). I really do love the fandom, though, so I'm putting a lot of thought into this. Hope you enjoy it!

I do not own anything in Durarara! I only own any OC's I drop into the story.

"You have got to be freakin' kidding me! You dumbass!"

One of the worst things in the world definitely had to be the ignorance of taxi drivers. Especially in a bustling city like Ikebukuro, where everyone has to be everywhere all at the same time. A disgruntled young woman stared down the taxi that had blatantly seen her and kept on driving and cursed furiously to herself after her exclamation. She pulled out her phone to check the time, and started to book it in the direction in which she had originally intended to go.

"The one day I let Hana take the car, I swear…" she groaned, picking up her feet faster and faster as she made her way through the crowds, "So much for being the 'considerate roommate'."

Her phone kept going off in her pocket; there was no doubt that it was from her boss (if she could even call him that- she usually couldn't stand to) being an impatient prick as always. He was probably just sitting at his desk, staring out the window, just waiting for her to arrive late so he could call her out and laugh his ass off about it.

And it wasn't even noon yet.

The sound of her feet hitting the ground seemed to grow louder and louder as she grew closer to the building. Her head was looking straight up at it, just waiting to see his face, smirking stupidly as usual. Sure enough, when she slowed down and approached the front doors, she got a fair view of him from the ground, and it was just as expected.

"My life is becoming a little too predictable…" she muttered to herself, pushing open the doors and heading into the elevator. She stood in there for a moment and let out an irritated sigh before pushing the button up to the floor where his office resided.

In the meantime…

"Are you this stupid all the time?" Namie asked as she set down the files and takeout box of Russia Sushi on Izaya's desk. The young man, Izaya Orihara, spun back around to face his assistant, Namie Yagari and continued to smirk devilishly.

"Whatever could you possibly mean, sweet Namie?" Izaya said, laughing not-so-quietly under his breath as he sat back in his chair and opened the takeout box. She had remembered his favorite- fatty tuna.

"Never call me that." She pressed a hand against her forehead and leaned against a bookshelf. "And you know what I'm talking about. How could you even think of dragging more people down with you? You're sick."

"I appreciate the compliment. Really, it warms my heart, Namie. And as for that, it's none of your business. What I handle with my subordinates is my business and mine alone."

"Well, you clearly can't handle anything. Look at what you did to the Sonohara girl, and the Black Rider, and Masaomi Kida, not to mention his little girlfriend."

"All dear friends whom I will sorely miss… But you know that they'll all come crawling back." He laughed again, but in a much quieter, darker way as he poked into his food. Izaya knew the mechanics of the human mind better than anyone, and he was perfectly confident in his words. The woman in the green sweater, who had the 'pleasure' of being his secretary was oh-so-tempted to slam the sushi straight in his face, but now was not the time. Maybe later, but not now.

A door on the knock came. "…Izaya?"

"Ah, Doll-chan~! Please do come in!" Izaya cheered, slowly clapping his hands together. The young woman who had been running halfway across town pushed through the doors, her bright blue eyes locking in on the rusty-eyed noirette man, and not looking happy about it at all.

"Why do you find it necessary to call me that dumb nickname?" she snapped at him, slamming down some more files from her bag on his desk. He felt accomplished- two pissed off females working for him in one day.

"Because it's adorable, and frankly, it suits you." He opened up the new folders and started scanning through them. "Oh, and by the way, you're late."

"Don't start with me, troll. Just don't." The young woman sat down in the chair on the opposite side of his desk and pushed a couple of locks of her dark brown hair out of her face, revealing even more irritancy underneath.

"Welcome to my everyday life," Namie droned, going through a nearby file cabinet. Izaya completely ignored her little side comment and turned back to the woman who 'worked for him'. In reality, they were more like subordinates or accomplices, but since he had been in the business for longer, he ranked higher. And therefore, she technically worked under him.

But it wasn't like she'd ever admit to anyone.

"So, what exactly do you want today?" she continued, clenching her hands for a moment and releasing a sigh. Her face grew a bit more serious as she came into focus.

"You're aware of my good friend, Shizu-chan, aren't you?" Izaya explained, tapping his fingers together.

"Well, I've never actually met him, but I know for a fact that he's not your friend, and he tries to kill you on a daily basis… So yes, I'm aware. What about him?"

"I need you to keep a special eye on him for me. It's seemed lately that he knows a little more than before… Like he's working his way into my inner sanctum of information…" He paused and took another bite of his lunch. "…So make sure to stop whatever he's getting at."

"I don't really understand what that means, but alright." She took her bag off of her shoulder and set it on the ground. "You're getting more paranoid every day, you know that?"

He just laughed. Her honest apathy towards him had always been humorous in his eyes, ever since the day they had met. It was partially why he had remembered her even after not seeing her for several years. She pulled out her phone and began clicking things into it with delicately rapid fingers; one could say she had potential for beautiful piano hands, but she could care to say otherwise. With her fist.

Thinking about the current task, she never grasped the rivalry fully between Izaya and this so-called 'Shizu-chan', otherwise known as Shizuo Heiwajima. Maybe it was just that he had left out crucial details, but the whole high school hatred origination made nearly no sense. She did know people she could ask for the real story, but it wasn't of much importance.

Actually, none of Izaya's affairs really had any importance.

For the next couple of hours, she was forced to dawdle around his office with him, taking up the usual Dollars business within their reign. It was rather mundane ever since the business with the Yellow Scarves and Saika had all died down, but she knew that her subordinate was planning something as usual. And as a natural response, she really wouldn't ask until he forced the plot right into her ears.

"Ah, Doll-chan, it seems that I'm still hungry… Would you come with me to Russia Sushi~?" Izaya finally spoke up in a somewhat pleasant manner.

"Yeah, sure. Got nothing better to do," she shrugged, pulling her bag back on. As they left the office, she waved bye to Namie and headed out behind him. In retrospect, she could sympathize with the secretary (even though she had extremely peculiar/creepy tendencies towards her brother). Namie had to put up with his bullshit even more than the brunette known as 'Doll-chan' did; at least she could leave a lot sooner, and could avoid him for relative amounts of time. But avoiding someone like him was not a simple task.

"Hey, Zumi-chan!" two familiar voices called out. Kyohei (aka Dotachin)'s van was driving by, and Erika and Walker stuck their heads out the window and waved to her. She waved back and laughed at the sight- they were entertaining to be friends with.

"Does anyone call you by your real name?" Izaya teased as they kept walking.

"Not particularly, no. At least not since I graduated high school… Which frankly, has been a while. I've gotten relatively used to it," she answered, letting all of the tension she had pent up go. It was a nice day in Ikebukuro, and she had gotten his stupid work done for the day, so why bother being too angry?

"Not even your family?"

"Nah, they call me Kaz. So does Hana. But whatever."

"Ah, how is Mori-chan?"

"You have a stupid nickname for everyone, don't you?" She sighed and looked up towards the sky. "She's doing alright…. And the reason I was late was because I let her take the damn car out to Tokyo today…"

"Always with the temper, Doll—" Izaya was cut off by a rather large trash can being smashed into him, forcing him to skid onto the sidewalk. Of course he, being who he was, got up, basically unscathed, looking ever amused and vigilant.

"IZAYA!" a loud voice boomed through the streets. In that instant, a tall, staggering blonde man in a bartender's suit came storming through, "Stay out of Ikebukuro!" Several unusual objects (vending machine, car, stop sign, etc.) were launched at the info broker, and he just booked it away, laughing insanely.

"Maybe next time, Doll-chan!" he called out to her before getting far away from where they had been standing. The blonde man, being none other than Shizuo, stormed right past her and after Izaya. She stared off after them both, and soon gave into laughter. That had been the most entertaining thing she had seen all day. His brown eyes were full with fire and rage; of course, she couldn't see much of them through his purple-tinted sunglasses, but it was undeniably there.

Well, he seems like a fun character, she thought, making her own trip to Russia Sushi, now feeling remotely happy now that the troll wasn't perched over her shoulder. It would only be a matter of small time before he came back, though.

"Hey, Nakashima! You come for sushi?" Simon said merrily, seeing her as she approached the famous restaurant of the city.

"Sure did. What's the special today, Simon?" she replied to the Russian man as her head tilted way up to look him in the face. He smiled and led her into the restaurant, where she ordered the odd special of the day. About halfway into her meal did she remember an important fact about the man she had just witnessed.

Holy crap… I work with that guy, don't I?

...and you still don't know her real name. XD R & R!
