The sadistic Teacher, as her alias implies, loves inflicting fear in her underlings and imposing that she demands constant obedience. Like the other characters in the franchise, the Teacher does not talk and her personality is shown through her actions. The Teacher also appears to have a very strong skull that it can bend down metals, as demonstrated when she chases Mono in the vents. Her most striking trait, however, is her neck- when she spots troublemakers from afar, The Teacher can stretch her neck by several meters, able to bend and flex it like a snake to move around obstacles and reach faraway targets. Her head is massive compared to the rest of her body, with baggy eyes, graying black hair, and a wrinkled mouth stuck in a permanent smug grin. The Teacher is a relatively large monster, with a height of about four times that of Mono and Six's. The Teacher is an elderly, slim woman who dresses similar to school teachers from the 1910s, with a gray skirt, a beige buttoned-up shirt, white socks, and black Mary Janes.
In her domain, children should be seen and not heard, and if one should be heard, they will never be seen again. Misbehavior will not be tolerated in The Teacher's classroom, and nothing escapes her cold, twisted gaze.
Her class is full of well - behaved children. An educator with an unusual ability to detect troublemakers.
