The battle progressed well for Osamu, or at least as well as could be expected. The hollows kept on coming, time after time until they became this near constant stream of foes. As soon as one went down two more were there, cramming into the gap but their sheer numbers limited their ability to move and the walls were a strong defensive position. Even the breach was holding firm, a wall of flesh and swords cutting down the foe time after time. Meanwhile, Osamu himself and his personal retinue held themselves in reserve, momentarily committing to deal with particularly troublesome opponents and then falling back, ready to deal with the next monstrous annoyance. Osamu alone was a fearsome enough foe but with his personal guards at his back he became nightmarish to stand against. They allowed him to operate in relative safety and security, Osamu could afford to concentrate more on single foes whilst his guard fended off everyone else. In this way Osamu could cut down beast after beast, no matter what their natures or tactics. Most importantly it allowed him to disregard the danger and risks of over extension. 

Whilst the line held Osamu’s Lieutenant was performing his assigned task admirably. It took him a few minutes as the group had to move at the speed of the slowest man, but eventually they worked their way through the residential area of the district and ploughed through the relatively light hollow resistance in the street. Soon they found themselves behind the right flank of the main hollow force and then they pounced. Attacking from the rear and sweeping along the line they took the Gillian by surprise. Beast by beast they fell and in quick succession. The golden bear wasn’t focused on holding ground, saving lives or any other objective. Just the business of highly targeted slaughter and living to tell the tale. As a result the could move swiftly and freely and by the time whatever intelligence controlling the attack realised what was going on, it was too late to stop the damage. The hollows were making an effort, trying to divert troops from the main offensive to hastily throw up a defensive line and turn their flank. But they always tried to draw it too close to the attackers and it was never ready by the time the golden bear got there. Enemy moral started to waver and coordination began to falter as the foe could not decide whether to commit to attack or defence. 

Osamu was plagued by no such indecision, taking his remaining reserve triganta he personally led it over the wall an in to a direct offensive into the enemy’s stalled front. The assault was tiny compared to the vast horde in front of them. But it was fierce, determined and led by a Captain who had nothing to lose. The zeal with which the assaulted was almost enough to make the enemy turn tail and run by itself, the swords provided the rest of the reason. But with a Captain at their front and a Lieutenant at their back, large portions of the foe had nowhere to go. Panicked, confused and very nearly surrounded large numbers of hollows were caught and crushed like a rat in a vice. Regular hollows and gillian fell in droves. Even adjuncha and some arrancar equivalents were caught in the net. Fifteen more minutes of pure, unadulterated carnage saw victory for the shinigami on this front. Osamu knew the battle here was over when he stepped across the body of his latest victim to shake the hand of his number two, fresh from removing his own blade from an unsuspecting eye socket. 

The congratulations were brief and to the point, the duo still had work to do. Taking their men back to the factory the men of the 10th went about preparing it for use once more. It had sustained cosmetic damage during the battle but the machines within remained intact. Still, it was not as simple as simply switching it back on. Lubricants had to be applied, raw materials stocked, moulds re cast, blockages cleared, systems check and most importantly, the furnaces had to be re lit. Furnaces of this degree and nature were surprisingly delicate beasts, once allowed to cool the internal heat shielding would crack meaning that re heating would almost certainly result in a vast and ferocious explosion. Every single heat shield plate would have to be replaced and no two were quite alike. Then, the furnace temperature would have to be slowly raised and the internal lining tested and proofed against the various chemical catalysts by exposure to small quantities of the materials. The whole process would take days at best, perhaps longer. But Osamu was still glad and full of anticipation. He had his factory, soon the first of his dreams would begin to take shape. 

Meanwhile, men of the fourth would shortly arrive at his location to begin treating the wounded. No division had escaped this day unscathed but casualties for the 10th were will within acceptable limits. The battle casualty replacement pool was well enough stocked to get them back up to a full complement soon enough. Reports of victorious, but more costly, battles gradually filtered back from all other fronts. When Osamu’s own men returned from the divisions he had hastily lent them to they brought with them accounts of well timed, simultaneous offensives that were well stocked with solid opponents. Some men murmured that this was some last great hurrah from the hollows, that the foe had expended their best and that it was an inevitable slide into defeat for the enemy. But Osamu didn’t believe that for a second. Today had been the first shot in a new phase of the war and without solid intelligence at his disposal Osamu had to assume the worst. Things could get a lot nastier from here on out and his current solution was an aggressive NDV recruitment drive, but with Kuroda sitting on his neck his ability to act was hamstringed. 

He was still thinking this through when reports of a flying Captain of the second also reached his ears. Apparently the woman had performed well, distinguished herself even. Osamu smiled at the notion and gave a tiny little chortle. It seemed his faith in that particular element of her was well placed. He considered sending her some gently mocking little token but decided against it. He had work to do and no one else was stepping up to the plate, pleasantrys would have to wait for a while. So, stepping out of his own thoughts he gestured to one of his men and declared. 
“Get the construction workers in here. I want these walls in pre occupation condition.” A silent nod of understanding and the man went off to fulfil his orders. Meanwhile Osamu gestured to another man, one of his personal runners, Osamu never trusted anyone else with anything sensitive. Leaning in gently Osamu whispered in his ear.
“Send the message to Captain Hayashi, she is to prepare the moulds, master parts and manufacturing documents for secure transportation. We begin as soon as the furnaces are ready.” It had been less than twenty minutes since the final blow had been struck and already Osamu was proceeding to the next phase of the plan. He feared for the future, he feared for what would happen in the coming days, weeks, months and years. But shying away from it would achieve nothing. So, on he went. It was the only thing he could do.
