This actually came about while I was in Forensics class-not dead people, it's competitive speech, debate, and acting (I'm the master debater lolol)-when a teammate of mine was giving a speech on chaos theory. Everyone's mind jumps straight to Shizaya when hearing about complex scientific theories, right? XD
Just more proof I'm a nerd there, I guess.

This story actually only gets written while I'm bored in classes...it is handwritten in my British Literature notebook (not British, btw.) and is actually way longer than this. Yeah, longest oneshot ever OTL Be warned.

I tried to keep this pretty IC-try imagining Izaya's theme in the BG when he talksXD hahaha.

Rated M for a reason *cough*gaysex*cough*
DISCAIMER: Durarara! and its characters are the sole property of Ryohgo Narita-NOT ME.

More reviews mean faster updates!~


"Damned flea." Hewajima Shizuo snapped and threw down his half-smoked cigarette and put it out with his now scuffed-up shoes. He had just caught sight of the bane of his existence—Orihara Izaya. The bastard was leaning over a balcony across the street, waving fingers at Shizuo and smiling.

"Oi, Shizu-chan~!" Shizuo growled and clenched his fists before cutting through the heavy traffic of Ikebukuro. He ran up to the balcony where Izaya had been, but the flea was nowhere to be seen.

"Dammit. IIIIIIZAAAAAYAAA!" Shizuo gripped the balcony railing beneath his hands and yelled before running off in the direction he presumed Izaya had run off to.


Izaya smiled to himself in the dark. He has been so pleased to hear Shizuo yell and Izaya was now confident of victory tonight. He giggled softly to himself as he ran his thumb over the blade in his hand. He could just imagine Shizu-chan's face when Izaya gave him a new nick and possible scar to add to his collection.

After hearing breathing and running footsteps pass the small cranny he was hidden in, Izaya stepped out, trademark smirk on his face. Shizuo was at the end of the platform, looking down below for Izaya.

"Well, well, Shizu-chan." Izaya drawled lazily. At this the blonde whirled around, angry grin on his face.

"Look who's back in Ikebukuro again, I-za-ya."

"You mean me?" Izaya feigned innocence, putting his finger up to his mouth and looking almost coyly at Shizuo.
The raven's brilliant façade was met with a growl and an ashtray flying towards him. He sidestepped it and laughed when he heard the pounding of plastic on metal and the screeching of brakes that accompanied the falling ashtray.

Izaya looked over the side of the rail and tsked. "Oh, Shizu-chan, look at what you've done now," his eyes flicked towards the ex-bartender. "You're so…violent~" Izaya purposely used the word sure to enrage the other man. Honey colored orbs flared to life behind cool blue shades before the blonde charged towards the raven. Izaya held his ground and before he knew it Shizu-chan's forehead was pressed against his own. He felt the heat at the contact and only grinned, crimson meeting amber.

The ex-bartender let out a low growl and Izaya just evaded the punch that was thrown his way. He quickly pulled out his flickblade and managed to get a slice in at the tall man.

Snick! went the button from the cuff of Shizu-chan's sleeve that Izaya had sliced. Izaya snickered to himself. Shizuo's uniforms were all dear to him and as such were a major berserk button. The blonde stared unmoving at the fallen, lonely white button on the balcony's concrete. After what could have been hours for all Izaya knew, but in actuality was only a few mere seconds, he looked up slowly and yelled.

"IIIZAAAYAAA! I-za-ya, you flea bastard, I'm going to kill you!" The brunette snickered as he jumped down the railing to a –seriously? — flagpole and onto the dark street below, quickly getting into this familiar game of cat and mouse.


Shizuo frowned at the now dismembered button lying on the ground. He then took off after the brunette, jumping over the balcony railing and stumbling from the drop into a run down the alley after him.

The ex-bartender ran after the smaller man throughout the labyrinth of streets and alleys of Ikebukuro. Tch, stupid flea. He should have known to stay away by now! The ravenette was quick; he always managed to stay ahead, jumping and dodging from all the flying debris. Shizuo kept in pursuit; the two running, jumping, throwing dodging, snarling, laughing, sneering.

Izaya rounded a corner, looking back at the blonde with a smirk and a wicked glint in his eyes. Shizuo ran past the same corner and stopped, slightly bent forward, chest heaving up and down, looking for the flea. It was only then that he noticed his surroundings. He was in Shinjuku, home to none other than the flea himself.

"The fuck?" Izaya never ran past Ikebukuro. That stupid louse…scared? Running home? The fact only served to further piss him off. "Izaya! Stupid coward flea! The hell're you at?" Shizuo's voice was rough from yelling and running. He clenched his fists, scanning the alley for any sign of that stupid fur-trimmed jacket.

"Protozoan Shizu-chan can't find me, ne?" Shizuo spun around to face the voice. The brunette tilted his head to the side, hands in his pockets.

Izaya ran his thumb over the ever-present flickblade, laughing softly to himself. He smirked as the blonde strode towards him, aura of anger nearly tangible. This was Heiwajima Shizuo, Monster of Ikebukuro—and Izaya's seemingly indestructible plaything.


The debt collector's hands were clenched at his side, visibly shaking with anger. Oh, how great! His Shizu-chan was in the mood to play! Izaya knew how this would go from past experiences—he would taunt, Shizuo would rage, Izaya would run…rinse, lather, repeat. In truth, Izaya wouldn't mind a change of pace after around seven years of the same game.

"Tell me, Shizu-chan—do you like butterflies?" The larger man frowned slightly, stopping a few meters from the raven . "I'll bet you don't; a monster like Shizu-chan would kill such pretty things, ne?" at this the blonde's brow twitched, and his jaw moved as if he had clenched his teeth, "Ah, butterflies. Has the protozoan ever heard of the butterfly effect? Allow me to explain: it is the theory that a tiny change can send a whole system spiraling into chaos!" Izaya flung his arms out for emphasis. Shizuo glowered at him, cool blue shades unable to hide the burning gaze of his eyes.

"What're you getting at, louse?" he snarled. Izaya felt his own expression his own expression grow dark and he smiled before stalking towards Shizuo, flickblade out.

"Well, I could do this," he said, tip of his blade poised at Shizuo's neck, edging closer and brushing the point ever so lightly against the skin there. Izaya stayed like that for a moment, gauging the other man's reactions. Normally, a fist would have shot out by no—

Izaya swiftly turned, evading the blonde's attack and caught a bit off guard by the sudden assault. Adrenaline began to once again course through Izaya, fueling him for the inevitable fight to come.

He sighed inwardly—that was great, but he had almost had it-a new change! He grinned anyway.

"I guess some patterns can never be broken, ne?" he said as he started to run. He was abruptly stopped when he realized his arm was captured in a seemingly iron grip.


Shizuo stared dimly down at his hand, unsure of why it had decided to grab the pest. His brows furrowed, thinking it was probably because he wanted to choke the life out of the flea. When Shizuo noticed the other's crimson eyes widen slightly before he regained his normal composure, he grinned darkly.

"Shizu-chan didn't want me to go, ne? I'm so flattered, but I really must be going now." The bastard had been slowly maneuvering a knife into his palm, and Shizuo, not feeling in the mood to be slashed, grabbed the brunette's other arm and pinned both of them to his side. Scarlet eyes widened and Izaya's body moved about, trying to free himself. Shizuo growled and shoved the flea into the wall of the dark alley they were in. The ex-bartender's body hummed with excitement—how long had he waited for this exact opportunity? He leaned in close, grin widening. His eyes flashed with excitement, and his voice was nearly as whisper as he said "No, flea. Please—stay here."


More updates soon! Tomorrow morning, probably. And I have not abandoned my other fic; just decided to type up this monstrosity:)
