Colby wasn't aware of how anxious the nekos really were. He couldn't understand their plight, their stress. Of course there were plenty of timid and weak humans that just want to get through school like anyone else. He stood patiently after Yuma's mention of her sister, now waiting for her sister with her. Though he was bored, it wasn't going to show on his face. Their height difference was quite comical, and it was a fun thought to waste time with. Suddenly, her sister arrived with the coffee and offered one to Yuma.  Colby looked away a little, deciding to ignore the rude look from her sister. When Yuma moved behind her sister and said what she did, Colby would finally look to the duo. "Colby Mayfield, I am a student of the highest honors." He began with, not looking away from Yumaki's eyes and this would be a fairly respectful notion. Of course his eyes could wander, but they wouldn't. "I heard your name from others, I took my time and thought it over. Many students here already know my name and while others offered to wear that collar instead, I declined." He didn't speak quickly or annoyingly slow. Colby wouldn't even seem uncomfortable. "I chose Yumaki because I know very little about her and she seemed kind. I know how teenaged boys are. I wouldn't be able to get any sleep if something bad happened-"  His eyes drifted to Yuma's sister's own eyes. "To your sister. What kind of man would I be if I had the opportunity to help Yuma and I chose not too?"
