Miss Circle is shown to be very cruel and violent. She shows no mercy towards students that fail in her class, killing them. She is also known to play favorites, such as Zip, Oliver and Edward.[4]

Miss Circle has spiky long hair with black horns. She lacks a neck, like many of the other teachers and students. She dons a black button up shirt with a white collar and white pants rolled up to the knee. She also sports tall black combat boots. Instead of a hand, she has a compass extending from her left forearm. The point of the compass is retractable, and she uses it as a weapon.

Miss Circle is the main antagonist of Basics in Behavior, where she makes her debut, and most likely the rest of the Fundamental Paper Education series. She is a teacher at Paper School and she kills students who fail or misbehave in class..
