Notes: So, this fic is in 4 parts. there's no particular name for each part because I started this as a one shot and it ended up rogressing to something way bigger.

Anyways, there's sexual content in this, on the third part, but it's nothing OH SO HORRIBLE. Is just normal yaoi sex. There's not even bondage in it and I'm sucker for that!

Anyways, I hope you enjoy it, somehow XD

Part 1

All in all, Jigen's life was going pretty smoothly for the past year. Since he moved to the US, everything was going fine. He was able to keep a low profile, keeping the amount of assassins and bounty hunters after his head to a minimum. At most, he would find one once a month, what for him could be considered a huge feat.

But more importantly, he was living alone. No one around for him to worry about or, like in most cases, to ultimately back stab him. He had enough with broken relationships, so, he decided to keep himself away from them, and he was doing a fairly good job.

To live alone like that was nothing new to him and it actually felt quite nice. The way his last relationship ended wasn't exactly pleasant, so he was more than OK with his present loneliness. It was almost too comfortable to sit around his small apartment all by himself, drinking and jumping through the TV channels until he would fall asleep on the couch.

In all honesty, he thought he had finally found a lifestyle he could really get used to.

That was yet another week without anything out of the ordinary, or so Jigen thought when he woke up on that Thursday morning, after a rare night of sleeping on his bed. It made no difference to sleep there or on the couch. He never really slept well and would always wake up countless times throughout the night. He couldn't really remember when he had a full night of sleep.

And as much as he wanted to stay in bed and try to sleep some more, he had things to do. He had to go out since he was running low on food and those weren't going to buy themselves, and he also needed to get some money and get it fast, since he was running low on that as well.

But first things first. He got up from his bed, not bothering to make it afterwards. It has been a while since he bothered about such things. That was actually one of the 'advantages' of living alone. No one would judge him if he let things scattered all over the place or if everything was clean or not...

He put on his regular attire and left the small apartment, but not before getting his gun and putting it on his belt, behind his back, as he always did. In his position, going out in the streets unarmed was just like asking to be killed.

Upon hitting the street, the city was already bustling with life. He choose to live in a place relatively busy like that because being somewhere isolated would make it easier for people to recognize him and hunt him down. Amidst all those people, he felt a little bit more secure.

While walking through the crowd, it was more than common for him to bump into people, and that day was no exception. Although, something slightly different happened.

Usually, when people bumped into him, they wouldn't even take a second look to apologize or anything. Jigen was more than used to that and he himself couldn't care less about the people he brushed against. So, when he ran into that random guy and actually heard him say something, Jigen couldn't help but feel slightly surprised.

"Sorry! I wasn't looking!" the man said, smiling as he looked somewhat embarrassed.

"... Nevermind," Jigen answered quickly and went back on his way. If the exact same thing had happened a year or so ago, he would be way more empathic about it. But he was trying to keep a certain distance from everyone, all the time, so even being slightly polite to people was out of chance.

It didn't take long for him to get to the small grocery store where he used to go. Getting inside, he quickly grabbed all the stuff he needed and, after paying, he left to the crowded streets again.

Despite having fallen into a routine of sorts, Jigen didn't really care. If being in a routine meant that he wasn't going to be taken advantage of, he was more than OK with it.

Although, sometimes his routine was broken by an occasional crook thinking it could take on him. And apparently, that was one of those days. As soon as he left the store, he felt that familiar feeling that someone was following him, and that wasn't just his paranoia talking.

Thinking that he was being followed by the regular assassins that were always after his head, he took a quick turn into an alley and then went to a slightly emptier part of those crowded streets. There was no need to involve other people in whatever mess he was about to get into.

When he finally took a turn and reached a deserted street with no exit, he heard footsteps behind him. And those came to a top, Jigen didn't bothered turning around before speaking.

"Who are you?"

"Would you please look at me when you are talking? I hate when people have their backs turned to me."

Jigen quickly turns around, recognizing the voice as the one he heard from the man he bumped into earlier that day.

"You again... Answer me: who are you?"

"You don't know me?" the man seemed surprised. "Why, I'm offended, especially after all the time I spent learning all I could about you, Jigen Daisuke."

The gunman stayed in silence. So, whoever that guy was, he certainly was looking for him.

"Why, my name is all over the news. Don't you ever watch TV? Or read the papers? I'm the one and only, Lupin The Third!" He said, a clear air of superiority on his voice as he spoken.

"I heard about you. I just never really bothered to pay attention to your face. If that's all you wanted to tell me, excuse me..." Jigen shrugged, as he started to walk towards the thief with the intention to go away.

"Well the thing is… He-Hey now! Don't leave me talking alone like that!" Lupin protested, his smile being replaced by a frown as Jigen walked past him.

"Look, unless you are here to try and get a reward on my head, you are wasting my time. And yours as well," Jigen kept walking, until he heard the click of a gun behind him, what made him stop on his tracks.

"Why, what if I'm here to get a hefty price for your carcass?" smiling again, Lupin kept on aiming his Walther P38 at Jigen, his eyes narrowing. "Would that be worth of your time?"

"Do you really know who you are dealing with?" the gunman gently put his bags down on the ground.

"Of course. Like I told you, I learned everything I could about you. I know there's a lot more to learn, but I guess that I have enough at the moment."

"If you know me so well, then you know you are going to die, right?" Jigen pulled a pack of cigarettes and a lighter from one of his pockets and lit up a cigarette, taking a drag from it. If anything, that thief could be a nice distraction, even if briefly.

"I wouldn't worry if I were you. No one can kill me," Lupin grinned, his eyes gleaming with excitement.

"You are quite full of yourself, aren't you?" the gunman turned around to face the thief. "I hate people like that."

"Well, and I hate assassins, so I guess we are even," Lupin felt his finger tense around the trigger. Even though he had no intention to shoot, he really couldn't hold back his enthusiasm. He had been following that man's tracks for a while and he finally had the time and opportunity to be face-to-face with him. That was quite the thrill.

Jigen reached for his gun and pulled it from his belt, pointing the gun on Lupin's direction, but not really aiming at him. At least not yet.

"Still, you are different," Lupin released the tension on his index finger as he kept on looking at Jigen's face, not really bothering about the gun pointed at his general direction. "You have something else that all those other mindless killers out there lack. I like that, and that's why I decided to make you an offer."

"Offer?" Jigen sounded slightly intrigued by that.

"See, it gets pretty lonely after a while to steal all those people and places all by yourself. I really could use a companion once in a while. So, what you say we become partners?" Lupin smiles warmly at Jigen.

Behind his hat, Jigen can't help but raise an eyebrow at Lupin's sudden change of demeanor. If that's what he wanted to say from the start, why pull off that whole act? Was that stupid thief testing him or something?

Either way, the gunman didn't really feel like accepting that offer. The last thing he needed was a partner. Specially one that seemed as self-conceited as the man standing in front of him.

"No thanks," Jigen simply responded, putting his gun away and picking up his bags once again, ready to leave.

"Wa-wait! Are you really going to walk away like that? I'm still pointing a gun at you!" Lupin shouted, stomping on the ground.

Paying no mind to what the thief was saying, Jigen just turned around and started walking away, much to the thief's consternation. He frowned lowering his gun and putting one hand on his waist.

"Well, I guess that all those things I heard about you were lies after all. I mean, you don't look that impressive," Lupin said, putting his hands behind his back. Suddenly, he hears Jigen drop the bags he had in hand and quickly pull his gun again, now aiming it straight at Lupin's head.

"You really like to push your luck, don't you?" Jigen lashed out at him. He was trying hard not to kill people unneededly, but that guy was asking for it.

"Don't you remember what I said? I can't die. You can pull that trigger but you aren't going to kill me," Lupin grinned, putting his hands up.

Bastard… Jigen thought as he cocked the gun and pulled the trigger. There was indeed a loud bang sound as he shot, but what came out of his revolver wasn't exactly what he expected. Instead of a bullet, the only things coming out were some strings of serpentine and a handful of confetti. Jigen couldn't help but stare at his gun with his eyes wide open, but he quickly shifted his attention to Lupin when he heard the thief laugh.

"Your face! It was priceless!" Lupin clasped his hands together, visibly satisfied with the outcome of his plan. "I thought you would notice that this isn't your real gun. Yours is here," producing another revolver seemingly out of nowhere on his hand, the thief threw the gun next to Jigen's feet, as he still looked at him in visible disbelief. "I replaced it when we bumped into each other back there. It was too easy."

Filled with anger and frustration, Jigen quickly grabbed his gun from the ground and shot at Lupin, who just seemed to avoid the bullets with relatively ease.

"C'mon now! I was just kidding!" Lupin shouted, jumping to a nearby balcony to escape the shots. "Where's your sense of humor?"

Even more furious about the fact that Lupin escaped his bullets so easily, Jigen quickly reached for the bullets he had in his pocket to reload the gun. Although, when he turned to look at the balcony again, Lupin was gone.

"Where are you?" the gunman shouted, his patience long gone by now.

"Up here!" The thief answered playfully, from a balcony behind Jigen, way higher than the one he was before. "Honestly man, you should go to some anger management sessions or something. It's not healthy to be that pissed off so easily."

"Grr… SHUT UP!" Jigen started shooting at the balcony's direction, making Lupin duck for cover.

Geez, this guy has quite the temper... The thief thought to himself as he heard the bullets hitting the cement wall behind him. Heh, that'll be fun! He couldn't help but grin. He was actually glad things weren't going to be that easy.

Soon enough, the gunshots attracted too much attention and both men could hear the faint sound a police car's siren approaching their location.

"Look at what you done!" Jigen said, putting away his gun and quickly grabbing hi bags again.

"What I did?" Lupin emerged from his cover, sounding highly bothered by the comment. "Excuse me, but as far as I know I wasn't the one going 'trigger happy' all over the place!"

Letting out a small grunt of frustration, Jigen started to look for a way out of that no exit street, to no avail.

"Hey. Mister Grumpy. Over there," Lupin pointed at a thin passageway that was almost hidden by a whole bunch of garbage cans.

Looking at Lupin and then at the way out, Jigen's blood boiled at the 'nickname', making him look up at the balcony again, ready to lash out yet another rude line at the thief, just to find out that he was already gone.

Son of a… Not having time to complete his thoughts, as the siren was getting closer, Jigen just ran to the small opening, pushing away one of the garbage cans to clear his path. When the police arrived at the scene, both men were long gone.
