Befitting of her occupation as a professor and a student, Rei acts mature and professional most of the time, making her seem cold and older than she really is. She absolutely dislikes having her time wasted, so she always gets to the point quickly and speaks in a blunt manner. She can also be condescending towards others, refusing to converse with people she does not find any worth to talk to. Due to this, she can sometimes go as far as ignoring a person if she sees a lack of worth in them.
Speaks in careful, polite phrases; frequently makes small clarifying remarks and gentle asides.
