~~Ache~~
She was gone.
Ulquiorra stood, rigid, as his instincts rammed and shrieked and tried to claw through the defenses he so carefully build in his years as a Hollow.
All because of the white little Hollow.
He should've left her, shouldn't have bothered with her at all, should've kill —
Ah. His instincts' shrieking and attempts to get through got more difficult.
Interesting. His instincts haven't revolted this noisily since . . . ever. This is the first time they even do anything other than tell him something, the first time they try to claw their way to the surface and try to take command; but he wasn't a Vasto Lorde for nothing (A/U: No pun intended) and brutally squashed down his instincts.
The simple reason his instincts were throwing such a meaningless argument was the white Hollow was gone.
Gone. Literally. Nowhere in sight.
And Ulquiorra, once again, found himself irked that the white Hollow had nil reiatsu and that the only way he could detect her would be by sight or sound; smell or sensor reiatsu abilities were useless against her.
How frustrating. Such a weak Hollow had such an effect on his instincts... Did she do anything? Ulquiorra asked that question to himself almost everyday; almost, because it was always night and thus Hueco Mundo had no way to identify time. Ulquiorra knew he allowed her to follow because she wasn't dead; the moment she drop dead was the moment he left her behind, plain and simple. Second reason was because of his curiosity, because the Hollow was still alive despite being so weak, because the white Hollow had nil reiatsu, because the Hollow wanted to follow him; and he found himself curious of those facts, especially the last one.
Notwithstanding, the white Hollow was gone. Perhaps she decided to leave if she didn't find what she wanted. Perhaps she was bored of following him around. Perhaps she didn't want to follow him anymore...
Whatever reason it was, Ulquiorra was irked he didn't notice she left.
With a final harsh push down his instincts, he turned and walked away to wherever his bone-armoured feet took him.
If the white Hollow left it was none of his concern.
Still . . .
His feet felt heavier than normal.
Why did his Hollow Hole burn?
It was perturbing.
His Hollow Hole was located where his heart was, and the ache came exactly from that place; yet, when he passed a hand over the void there was nothing wrong with him. No poison or wound, no scar or infection; nothing.
That was the first time Ulquiorra wondered about the heart he heard humans and Shinigami talk so fondly of, and the beginning of a search long sated.
