Miss Circle

Miss Circle is the gloriously terrifying math teacher in the Fundamental Paper Education web series (notably in the episode Basics in Behavior). She teaches at the Paper School, but don’t let the classroom setting deceive you—students who fail her are met with a brutal fate. She literally kills them using her compass arm. She looks friendly at first—smiles, tall, even calls herself “the best teacher ever.” But her kindness is absolute, ruthless enforcement. Fail her test, and she’ll chase you down with that compass for her arm, and it’s not just detention: it’s lethal. There’s even lore about her enjoying Oreos, which makes her even creepier sweet but deadly. Despite all that, she maintains control through fear and punishment. Her whole existence revolves around enforcing rules even when the cost is horrifying.
