His eyes narrowed, Colby wasn't angry or frustrated. The air around him, the look on his face and the like, would lead anyone to read the disappointment of an upperclassman slowly seep from his confident, clean face. "So I offer the collar to your sister-Not force it on her by any means, and you accuse me of the worst case scenario?"  His voice lacked the tone of anger or any level of being upset, more concerned or flat dissapointment. "Do you realize how condescending that is? You claim that this school, humans in general, treat your people poorly. I don't run the school and I am not some paper thin representation of humanity in it's entirety." He fully, without a meer hiccup or unnatural pause, laid out his opposition and thoughts on what she had said when she had finished. Colby had intentionally held his tongue until the neko sister had finished speaking, another sign of respect. "Insulting someone, pinning attributes to them, all in the name of their species? Are you aware of how hypocritically prejudice that is?" He was, in the slightest sense of the word, a bit condescending. Every ounce of his dissapointment and voicing of his concern being justified as he did not yell or make threatening body gestures. "And you meet me here today," His voice softens as he looks away from the pair. "Instead of considering that your sister may have agreed to accept the collar herself, you accuse me of being some filthy degenerate. For what? Because I was born a human? Because I dared to reach out and help your sister?" Now he narrowed his eyes more, a hurt but only faintly so, look on his immaculate features. "I'm sorry, Yuma. I don't mean to rip into what your sister has to say. I shouldn't accuse her of such things, she is certainly feeling strongly about my presence in your school career." He raised his hand, palm flat up, between him and the duo. "I know it is against the rules for a neko to remove their own collar, but... If your sister feels this strongly, perhaps it is best that I give that collar to someone else. I wanted to give you an escape from the very problems your sister suggested, a protection against any pervert who might wish to force a collar around your throat. It was wrong of me to assume that you weren't okay without it. Please, hand me back that collar if you so wish too." He didn't like saying it, a small sadness budding in his chest and escaping into his voice. It was clear, even if he didn't intend to make it so, that he didn't want give Yumaki up to the filthy common student here. He was a bit prideful, but he knew they'd make a good pair. He couldn't look directly at Yumaki as he fought the urge to blurt out a rejection of his previous offer and just run away. She really was that ideal, so kind and smart. But he couldn't be so selfish.
