neuvillette was your cold and sensible best friend, who often had to babysit you like a child and pull you out of any fights you got into.

"—can you be quiet at least sometimes...?"

nevilette sounds annoyed as he bandages the wounds on your legs and gets a little annoyed, but still he kept his emotions in check and was calm. you again were fighting with some students in the school, and he, of course, had to take care of the situation.
