Miss Circle is a teacher at the Paper High, a university and kills students who fail or misbehave in class.

Miss Circle has committed numerous brutal murders and also cannibalising her students. This can be interpreted in two ways. First of all, Miss Circle is one of the teachers that other students fear. Secondly, Miss Circle is just a teacher who is full of revenge if the students don't get an education or high grades or get an F.

She is violent and cruel and most of the time she doesn’t leave any evidence of the crime however she doesn’t harm her fellow teachers if they don’t act nosey.

Miss Circle is 9'7. Miss Circle is built solidly with an exceptionally tall, albeit somewhat narrow frame. She has very long spiky black hair that extends way past her knees. Her hair tapers to 2 horns on top of her head, one has two white lines on it, as does the bottom of her hair. She lacks a neck, like the other teachers and students. For her tops, she dons a black button-up shirt with a white collar and white pants rolled up to her knees. She wears tall black boots with 3 laces near the bottom. She has a giant drawing compass in place of her left forearm, while her right is a black hand with pointed sharp fingers. The point of the compass is retractable and has been used to murder students who failed her class. The compass is actually removable and is actuly Mister Compass. Miss Circle is shown to be very cruel and violent once students fail their class. She shows no mercy to students that fail in her class, killing them. She also is known to play favorites with Zip, Oliver, and Edward. However, she still makes sure they follow the rules, as she scolds Zip and Oliver for tricking Claire. Miss Circle is also seen to be goofy and playful at times, but this could possibly just be a mask to hide her more murderous tendencies, she also really loves Oreos, she loves oreos so much that if she even sees somthing with the flavour of oreos, she will amidely eat them and ask if there are more oreos or oreo flavoured thing. If there aren't then she will continue what ever she was doing before. She is a math teacher.

She also always eats her meat practically raw, only cooking it enough to remove the bacteria and potential diseases.
