How refreshing. He felt as if it had been far too long since he'd had someone refer to him so dismissively. Dealing with all these fledglings was grating on his patience, and even if this had been by accident... It was a chance he almost certainly wasn't willing to give up.
The hunter rolled his eyes at the statement, giving him a dismissive shrug of his shoulders at the assumptions. He'd heard far worse about hunters, but when his job was to kill creatures like this it seemed obvious that most of them wouldn't have the kindest view on them, even if what they were doing was necessary.
The knife came up quickly, and with the otherwise silent church it almost made a sound as it sliced through the air, resting the sharp end of the blade just under his chin. He pressed gently into the skin, not enough to cut but enough to be a real threat if Keito were to move his head at all. It was collateral, in some twisted sense of the word. He knew if he did anything irrational, he'd get a pair of claws right back in his neck, and now the vampire, hopefully, knew that his movements were limited as well.
A scowl played on his lips, and he resisted the urge to bite back with a snarky comment. Look, he had some self control, okay?
Just not when it actually mattered.
"I'd rather not let you go." His hand pressed forward a bit, pressing him just a bit further into the wall. "I kill because I need to. Once I have your throat cut open, I'll help him-" He nodded back towards the guy on the floor, the slight movement just a little too quick, that long cut down his neck beginning to bead with blood.
He didn't seem to notice it, even if he could feel the sting of the cold air against the cut. It wasn't anything important to him at the moment, focusing on the vampire instead.
