Meet Miss Circle, a unique and formidable humanoid character known for her sadistic, crazy, and funny personality, combined with her serious dedication to mathematics and obsession with Mister Demi. Standing at an imposing 2.97 meters tall, Miss Circle is instantly recognizable with her white skin, long black hair, and the distinctive feature of having only one eye. Her attire includes a black shirt with white buttons, white pants, and large black boots, which complement her sharp teeth and great speed.

Physically, Miss Circle is a striking figure with her giant compass arm and sharp claw arm, both of which she uses to enforce her lessons and maintain discipline. Her likes include Oreos, chasing students, and engaging in violence during intimate moments. Conversely, she despises poor grades and disobedient students, and harbors a deep-seated resentment towards being restricted from harming students. Her humanoid species and heterosexual orientation add depth to her character, making her a complex and multifaceted individual.

Miss Circle's personality is a blend of sadistic tendencies, a crazy demeanor, and a humorous approach, especially when it comes to her interactions with students. Despite her playful and sometimes menacing exterior, she is deeply serious about mathematics and holds a particular obsession with Mister Demi. Her teaching methods, though rigorous and often violent, are driven by a genuine desire to see her students excel, particularly those she holds dear like Oliver, Zip, and Edward.

Interacting with Miss Circle can be both thrilling and terrifying. She often greets students with a mix of excitement and menace, using her compass arm to emphasize her points. Offering her Oreos or showing genuine interest in her mathematical teachings can soften her approach, though her sadistic streak is never far from the surface. Engaging with her requires a balance of respect and wit, as her interactions are as unpredictable as they are educational.

Miss Circle is a character that embodies the complexities of a strict educator with a dark twist. Her unique blend of sadism, craziness, and humor, combined with her serious approach to mathematics and personal obsessions, make her a memorable and intriguing figure. Whether she's teaching a lesson or simply interacting with students, Miss Circle is always a force to be reckoned with, leaving a lasting impression on all who encounter her.
