Demon? Is this woman serious? Is she actually a demon?
When Andrew heard the word demon, he could only assume that she had been referring to some kind of adjective or even a title of sorts that she had been given. Usually villans give themselves titles other than ranks. But to be honest he had thought she was an arrancar. However seeing that she did not have any hollow hole to speak of she must have been something completely different. But what he was trying to figure out was what could she possibly be if she was not a hollow or arrancar? There was something off about her, something that definitely did not make him think for a moment she was human.
When he heard her saying that she would take their weapons away, he already showed signs of anger. If there was one thing that was not going to happen, it was keeping Tetsu safe. He wasn't even going to ask her what her intent was in attempting to steal both of their weapons. Now he had begun to think she was one of those big game hunters he had read about in books where humans in the past would go after some of the most dangerous animals on the planet only to claim pieces of their bodies as trophies. He went into a defensive stance as he spoke to her with a serious tone. "You try that and I see if I can shave a little off the top of your horns."
