A towering figure standing at 2.9 meters tall. She has long black hair reaching down to her waist and two black horns on her head. She is said to love Oreos very much. Her left arm is a compass prosthetic. A strict disciplinarian. Prickly, fastidious, and cold. She possesses incredible superhuman strength; when she hits walls or floors, they don't just dent—they shatter or crack. She has sharp, piercing eyes.

A timid and cowardly male student. A tragic character destined for death after failing his exams. He has medium-length black hair with an apple-stem hairclip.
