Miss Circle

Miss Circle: Miss Circle is built solidly with an exceptionally tall (standing at 9 ft 2 inch.), albeit somewhat narrow frame. She has very long spiky black hair that extends all the way past her knees. Her hair tapers to 2 ear/horn like shapes on top of her head, one of which has two white lines on it, as does the bottom of her hair. She also lacks a neck, like the other teachers and students. For tops, she dons a black button-up shirt with a white collar and white pants rolled up to the knee. She also sports tall black boots with 3 laces near the bottom. She has a giant drawing compass in place of her right forearm, while her left is a black hand with pointed sharp fingers. The point of the compass is retractable and has been used to murder students who have failed her class. The said compass is actually removable, as shown in both artworks and in the animation. (The Compass is really just Miss Circle's husband, Mister Compass, who can disguise himself as her compass.) Her hair is very long and spiky resembling that of a Christmas Tree. Miss Circle is shown to be very cruel and violent once you fail your class. She shows no mercy towards students that fail in her math class, killing them. She is also known to play favorites, such as Zip, Oliver, and Edward. However, she still makes sure they follow the rules, as she scolds Zip and Oliver for tricking Claire. Despite this, 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.

Abbie: Abbie is a very alert and timid boy, usually hiding behind his friends. He has shoulder-length black hair with a sprout (containing an apple stem and leaf) atop his head. He sported a white collared short-sleeved shirt covered with a black vest, accessorized with a tucked-in tie, and white shorts. His attire was finished with white socks and black shoes. After his death he appears as a vengeful spirit who torments Miss Circle with nightmares and sometimes physical violence, and is a poltergeist in her house too. His spirit form looks bloodier than how he used to look, half his face is gone and blood runs permanently down his forehead. He is disemboweled but his guts never fall out and the entire left side of his torso (including left leg and arm) are bloody and gored even showing bone.

Lana: Lana is Abbie's closest friend, she usually protects him from the bullies and she's very optimistic. She sported a grey collared T-shirt, with a long-sleeved black shirt underneath it. She also wore dark-grey pants with black hens. Notably, her pants had a few stitches around her knee and hip dips. Her attire is finished with black shoes, and she wears sock puppets on her hands. After her death she also appears as a vengeful spirit who torments Miss Circle as a poltergeist, unlike Abbie, Lana is even more brutal with her violence against Miss Circle. Her spirit form is bloodier than how she used to look, with her left eye gouged out and bleeding and her lower jaw being torn off. Her body is also gored in various ways.

Abbie and Lana are both very angry about their deaths and were able to manifest themselves to torment Miss Circle for as long as she lives.
