The night was dark and unusually quiet for Ikebukuro. The famous dangers of the city appeared to be laying low, namely the colour gangs, the dollars, Heiwajima Shizuo, the slasher…well, you get the picture.

However, one of these taboo 'people you must not piss off' was walking purposefully towards a shady bar near Sunshine, the information broker Orihara Izaya. A smirk curled his slightly feminine face as he opened the door; a blast of hot, smoky air hitting his chilled face.

No one looked up. It was one of the rules of the place after all, to mind your own business, a rule which probably extended over the whole of Ikebukuro.

Spotting his client, Izaya made his way towards the gloomiest corner of the already dank room. As he took his seat, his nose wrinkled minutely in disgust, though he was careful to keep the experienced, self assured smirk on his face (the client needed to know that Izaya was the one in control after all).

He had done business with this client before and so was used to the leering gaze of the otherwise reasonably attractive, albeit wrinkled, middle aged man. It was the downside of being able to read and manipulate people so easily, that you could always tell when some were undressing you with their eyes.

This underground business leader was no exception, and so could never earn Izaya's respect even if he did run a very efficient crime ring. Of course, none of his thoughts showed on his face as Izaya casually prompted the European man.

"Long time no see Karl-san. On the phone you said you had some information which would interest me. If so, maybe we could trade a few se-cr-ets" Izaya purred, dragging out the word secrets as his playful nature took over.

Karl squirmed slightly in his seat, a slight sheen of sweat glistened on his face, no doubt built up from the hour Izaya had left him to wait. A predatory gleam entered said information master's eye, really, humans were such fun.

When Karl spoke his voice was pompous, yet he stumbled over his words now and then as though scared of his present company, "It's about Heiwajima Shizuo. Everyone knows you two have a…err...connection". Izaya's face remained playfully superior, but inside he had suddenly become very interested, "My, my…and what has Shiz-chan done this time?"

Karl had taken a handkerchief out and was now dabbing at his face. "Well, I'm going to need some information from you first. T-that's the way business works after all right?"

Izaya's reply was a smooth "of course", but once again his irritation at this man had resurfaced. His eyes had roomed over Izaya's body at that last comment, obviously thinking over what he would like to do with Izaya outside of 'business'.

Resolving to give some of Karl-san's secret trading routes over to his enemies later, the brunette reached into the fur lining of his jacket where his knife was often kept. Where Karl knew his knife was kept, having seen him in action. Human instinct and experience therefore caused the nervous crime boss to freeze until a plain envelope was produced from the jacket. Izaya giggled childishly at the irritating man's display of fear.

The envelope was placed lightly on the table, and Izaya resumed his slouched, yet somehow still graceful posture. Now surveying Karl-san expectantly, he considered the information inside the seemingly average envelope. It wasn't too important; in fact he probably wouldn't even notice it missing. However, it did contain information on the members of the local law enforcement, helpful to Karl-san's line of work.

Karl's clammy hand scrambled for the envelope greedily as he answered Izaya's piercing gaze in a wheezy tone, "He's the older brother of that pretty boy top idol, you know, Hanejima Yuuhei. Apparently, H-Heiwajima cares for him very much. You might be able to use h-him to get to Heiwajima". Disappointment settled in Izaya's gut, which this time he didn't bother to keep from his face, causing Karl to flinch back. "Is that all, Karl~san?" Came the playful voice again, dragging out the crime lords name with a touch of sadism.

That information had been nothing new to him. Not to mention, he would never use it against Shiz-chan, dragging a relative into their game just wouldn't be fun. The game of cat and mouse was between just the two of them, neither of them knowing who was which animal.

In a way, Izaya supposed it was a love hate relationship, at least on his part. Shiz-chan was the one member of the human race that stood out. He was the one human Izaya could never read due to his unpredictable temper, and he both loved and hated him for it. Izaya let out a small, almost demented giggle, causing Karl to press back against the seat in trepidation. Izaya didn't notice.

He stood up with an exaggerated sigh and strolled, almost cat-like, towards the door. Izaya had long ago decided Shiz-chan was his obsession, a prey he considered as solely his. Shiz-chan was the person he felt more intensely for than anyone else.

As he opened the door back out into the night he wondered vaguely whether that was what love was after all. Chuckling, he decided that he did not care as long as their cat and mouse game continued.

Izaya was about to leave when Karl-san's rushed, slightly apprehensive voice stopped him. "S-so I take it you don't mind if I share this information with the colour gangs, and other people who might want it." Izaya froze.
