Mosaic City, located along China's coast, is quite large city sometimes called the Crossroads Between Nations due to its diverse population. While it was once a large tourist spot, the city was placed under a blockade as the military appeared claiming there was a radiation leak. The true hazard, however, is much more sinister.
The last time she had been in the tower, Pyxis had run up against a barrier preventing her from continuing past the second...well, stratum was a good enough word for it. They didn't correspond to individual floors, and the only distinct dividers between them were things that would have appeared after the place was infested with shadows. Now, however, the barrier was gone, and she could continue further on.
As she climbed the stairs onto a floor she hadn't visited before, Pyxis noted an even higher concentration of shadows than on the last two strata. Her sensors were returning readings from all directions, while visible signs of battle were very few and far between. Appropriate, since the area had previously been blocked off. This area would take much longer to get through.
Pyxis soon came face to face with another gigas, oddly wearing the tattered remains of a human's business suit. From the way it was torn, it was easy to assume that the suit had been intact until the gigas tried to put it on, but...no, that wasn't important at the moment. Pyxis immediately opened fire on the shadow. The increased firepower of her new, upgraded spread guns did impressive damage both to the gigas and the surrounding office space, but didn't have quite the same penetrating power as the old ones had on the last gigas she had fought in the tower. The gigas returned Pyxis's attacks with a straight punch, although it did little against her own armor. This continued for a couple more rounds, with Pyxis shooting at the ironclad humanoid shadow and the gigas punching her in return. It was only on the fourth exchange that the gigas managed to do anything different. This time, it managed to brace itself against Pyxis's attacks and reflect them right back at her. Her own bullets came flying back at her, along with two spear-hand strikes from the gigas. Pyxis stepped back to put more distance between herself and the brawler, calling forth Pandora to heal herself in the meantime. The gigas, evidently noticing that she wasn't resisting its piercing attacks as easily, closed the distance again and hit her with another pair of spear-hand jabs. This time, Pyxis powered through it, summoning Pandora a second time. A ghastly fist wielding a curved blade emerged from the box her persona carried, bringing it crashing down on top of the Gigas's head, finishing it off.
