Origin

Characters: Law, Franky. Rating: K. Warnings: None

With the absence of one Monkey D. Luffy, Law had hoped that he would be at last permitted some peace and quiet, especially as he was now on board his own ship and therefore the captain in charge (while 'alliance' meant the captains were on equal terms, it was difficult not to feel on the back foot on board the Thousand Sunny, especially as her captain didn't follow traditional alliance rules anyway). He still had four of the Straw Hats with him, but in the grand scheme of things he thought peace and quiet still wasn't too much to ask for; Zoro-ya and Nico-ya preferred keeping their mouths shut anyway, Nose-ya was still terrified of him and Robo-ya…

Well, Robo-ya was turning out to be the problem. Law chided himself for not realising that the shipwright, who had built both the Thousand Sunny and its personal submarine, would be incredibly interested in the Polar Tang, which was a far more superior specimen than the Shark Submerge (although Law would admit the quirky submarine was well built for its size and purpose). In the confined space, the cries of SUUUUUUPERRRR reverberated nauseatingly, and no amount of creativity employed by the Heart Pirates (Law included) to block their ears was even remotely successful. Irritatingly, the other Straw Hats seemed totally deaf to his cries.

A sacrifice was required, and as Law looked around at those of his crew in the area, he realised he would have to be the victim. As difficult as it was to believe, his time with the Straw Hats had mildly desensitised him to their antics and he only had to take one look at Penguin and Shachi, concerningly out of sorts even before the cyborg's cries had begun, to realise that there was no way his crew would survive close quarters with the shipwright for any length of time with their sanity intact.

Choosing not to ponder what that implied of his own sanity, he followed the noise to find not just Robo-ya, but also Nose-ya prodding at the security lock of the engine room. Unnerved that no alarms had been set off at the intruders' attempt, and also relieved that Nami-ya wasn't around to assist otherwise they would have definitely succeeded in gaining entry unsupervised, he strode up to them and placed a hand over the passcode input.

"Torao-bro!" Robo-ya greeted cheerfully, not at all abashed to have been found trying to force entry into the most delicate part of a ship that wasn't his. Behind him, Nose-ya at least had the decency to cower. "Just the man! Show us around, would ya, bro? This girl's a SUUUUUUUPERRRRR beauty, yeah!"

Law wanted to refuse. As the ship's captain, he had every right (and with the absence of Mugiwara-ya he technically held captaincy over the four guests although he knew full well that only Nico-ya had any inclination to obey him and even that was on her own terms). However, these were Straw Hat Pirates. He had never, either through personal experience or the newspaper, heard of a single occasion when the Straw Hats didn't get their way in the end. The fact that the security alarm on the door had already been bypassed without his knowledge, and that they'd had no qualms about even trying in the first place, made it clear that sooner or later they'd be back, and he didn't really want to unduly punish his own crew by adding an extra watch to the rota (especially as he could quickly narrow down who had a chance of stopping the Straw Hats one-on-one to barely a quarter of the crew, including himself – there were reasons the entire crew had their own bounties, after all).

Thus, with a sigh he gestured for the two of them, apparently now three, as Zoro-ya had materialised while he was considering his options and (while Law was certain the swordsman hadn't intended to find his way there) was standing with all the poise of a man who was exactly where he wanted to be, to follow him to the nearby locker room, where he located boiler suits for them all.

"I am not treating you for stupid injuries," he ground out when all three looked at the Heart-emblazoned outfits dubiously. "The Polar Tang's machinery is far more dangerous than the Sunny's." Having seen both, he felt qualified to make such a claim (the Sunny ran on cola, for goodness' sake! Then again, with a captain like Mugiwara-ya, a child-safe mechanism was probably wise).

Nose-ya was first to cave, and Zoro-ya followed suit after Law began to pull his own on – a nice yellow colour, to distinguish him from the rest of the crew at a glance. He wasn't even sure what persuaded the cyborg to eventually pull on one of Jean Bart's spares, but he'd learnt to never look a gift horse in the mouth, especially not when the Straw Hats were involved.

Hoping he was not going to regret his decision, Law keyed in the code, making sure to block the others' line of sight to the passcode as he did so, and the door slid open with a quiet hydraulic hiss, revealing the heart of the Polar Tang.

Clione, the crew member currently tending the engine, looked up in surprise before looking at Law questioningly. Law simply shrugged as Robo-ya carefully advanced into the room, eyeing the equipment with a look Law couldn't quite name. It was almost as if it was what he'd expected, although Law was under the impression there were little to no other submarines of the type in existence. It was possible Robo-ya had the required genius to work out what was most likely, though, so he tried not to dwell as Nose-ya started asking questions. Law was glad for Clione's presence, as he didn't know the answer to many of the more technical ones (the Straw Hats had no room to comment on that, though, as Law was confident Mugiwara-ya knew about as much about the workings of the Thousand Sunny as he did the Polar Tang, if not less. Mugiwara-ya likely would proclaim it all a 'mystery' or simply point out it was Robo-ya's job to know).

Eventually, Clione became the main spokesperson and Law perched himself down on a bench near the entrance (Zoro-ya was sat on the same bench but closer to the door, and seemed unnervingly like a jailer; Law put the thought that he was being intentionally trapped far out of his mind, paranoia would do him no good). It was hot in the room, almost unbearably so to Law, who had never managed to shake his North Blue roots of preferring the cold, even if he hated winter, but Robo-ya and Nose-ya seemed a long way from running out of questions, so he endured in silence, watching the two like a hawk. Allies or not, unconventional allies or not, he refused to let them near the delicate part of his ship without strict supervision.

It was probably an hour before their curiosity was sated, just in time for Ikkaku's shift to begin – she gave him a quizzical look as she entered to relieve Clione, which Law responded to with a pointed glance at their guests – and he managed to shepherd the three out of the room and into slightly cooler air.

It took no time at all for Zoro-ya and Nose-ya to strip out of their borrowed boiler suits and disperse back towards the living area of the Tang (Nose-ya kept tugging at Zoro-ya's sleeve when he tried to take a wrong turning), but Law waited for Robo-ya to finish as well before daring to leave. Robo-ya appeared to be being intentionally slow, and Law wasn't sure what to make of it as he folded his own boiler suit and put it away neatly.

"Torao-bro," Robo-ya began, uncharacteristically serious as he finally freed his legs from the suit. Law turned to give him his full attention. "Where did you get this girl?"

It was a loaded question, and Law wasn't sure he wanted to know why Robo-ya was asking. The cyborg had somehow positioned himself between Law and the door to the room, though, and while Law could teleport himself out with a Room, he didn't like the unusual behaviour. He was getting enough of it from his crew as it was, he didn't need the predictably-unpredictable Straw Hats adding to the headache.

"What does it matter?" he hedged. There was a click, and a compartment opened up in Robo-ya's arm. Rummaging around, the cyborg withdrew a wad of paper.

"Those two years," he began, and suddenly Law knew it was serious because the Straw Hats never talked about the years they'd vanished from the limelight, "I was on Karakuri Island – Vegapunk's home island. He'd left a lot of blueprints behind, and I thought they were all incomplete projects, so I took some with me when I left." He offered the paper – blueprints, Law realised – to him. "Seems like this isn't incomplete after all." Law took them and glanced down, only to freeze.

In his hands were the unmistakable blueprints of the Polar Tang.

I'm convinced the Polar Tang must have been built by Vegapunk or a scientist of similar calibre, because it's so technologically advanced. While there are other submarines in One Piece, the Polar Tang seems to be one of the most advanced from what we've seen. What I want to know is if it has a kairoseki hull like the Marine ships (how else did it get away from Amazon Lily without a Kuja escort)? Why the Polar Tang was in North Blue but the blueprints were in the Grand Line? Well, Vegapunk canonically has some connections with North Blue, so while he designed it in the Grand Line it was built in North Blue.

This is a sort-of companion piece to Calamity (chapter 12), and Zoro's job was to make sure Law stayed away from Robin while she made her inquiries.
