Mayo Mitama is a student in Nozomu Itoshiki's class.  Her distinctive feature is that she is mean, in appearance and in personality.  She is always doing bad things, however because no one believes that someone who looks so mean could actually be mean, everyone assumes she can't possibly be the one doing it.  She is student #30. Her name is derived from mita mama yo, meaning "exactly what it looks like".
