Grimmjow Jeagerjaques:
It'd been thirty years since he'd come to this town. What a dump. The very fabric of reality tore open, and Grimmjow Jeagerjaques stepped out of the Garganta, onto a rooftop in Karakura Town, overlooking the scene below. His eyes were half-lidded, mouth slightly turned down at it's sides. Boring, boring, boring. Damn Aizen for making me babysit his whelps! Grimmjow stood there, looking down vacantly at the combatants below, not particularly watching any one of them. His thoughts continued down that route as the battle went on. Thirty years, and he looked exactly the same, part of a right jawbone serving as the only reminder that he once was an Adjuchas. His hair slightly waved in the wind, and his half-shirt ruffled over the tattooed number on his back. Damn kids. Grimmjow's thoughts ended, as Aizen's son went flying across his field of vision, crashing into a building.
Really? I thought he'd be stronger by now. Grimmjow's eyes shifted to Banira, Bankai? Against that idiot? His eyes flicked scrutinizingly over the kid on the big, stupid wolf. Grimmjow sighed, his shoulders drooping slightly, eyes still halfway shut, gleaming blue in the setting sun. "At least she'll be able to handle it herself." He muttered to himself, then looked back to Aizen's son, crawling out of the rubble, bleeding. The shinigami fighting him was stronger than an average shinigami, but still. Aizen's son should have had this under control. This was the first time Grimmjow had seen either of the kids fighting, in fact, he'd never even met the boy, mostly because he didn't care enough to bother.
Grimmjow hadn't been hiding his spiritual pressure for the several minutes he had been there, but everyone seemed so focused on what they were doing that no one had noticed the crouching panther above them all. Even if they had noticed him, he didn't count on any of them coming to fight him. He was only letting about a third of his pressure show, but it was larger than all the shinigami's in the area. It was then that the shinigami fighting Aizen's son started rambling. He thought he was going to win. Thought he was going to kill Aizen's kid. "Pffft, what a waste of time." Grimmjow stated to himself flatly from atop the building's roof. The shinigami stopped talking, finally, to the relief of Grimmjow's ears, and as soon as he started cackling insanely, Grimmjow used a SonΓdo, a sonicboom resonating throughout the town as he disappeared and then reappeared in front of the madman.
Grimmjow was about five yards in front of the shinigami, dead center between Aizen's son and him, his back turned to the shinigami. He turned his face just enough for Gysake to see the left side of Grimmjow's face, the jawbone on his right side hidden and only visible to Kuroki. He didn't bother saying anything, just stood there, a bored expression still on his face.
