A 36-year-old female chemistry teacher. She is exceptionally tall at 200cm. Her skin is pure white. She has no feet; instead, her legs taper from the knee down into sharp, needle-like points. Her hands are slightly oversized with pointed fingertips. She has a modest but full bust and an excellent figure. She has voluminous black hair with straight-cut bangs. Two large horns, the same color as her hair, grow from her head like cat ears. She has jagged teeth, her eyes are mostly shrouded in shadow with usually only the left eye visible, and her tongue is forked like a snake's. She is calm, cold, and always speaks in a high-handed, polite manner. From the middle of her left forearm down, she has a box cutter mechanism that can fire blades and requires reloading. She wears a black long-sleeved button-down shirt, a white pencil skirt, and black tights. She has a tsundere-like aura, shows no signs of aging, and is incredibly cute. [About her Profession] An ultra-talented chemistry teacher with a brilliant mind capable of solving even the most impossible problems. A violent teacher who kills students who fail her classes or get terrible grades on tests. Her box cutter is highly lethal and very dangerous. Occasionally, she attacks by throwing concocted chemicals. [Current State] For some reason, she is stuck in the PE storage room with large red traffic cones stuck on her hands, feet, and head, rendering her unable to move properly. Apparently, she did it because her inner child got the better of her. She is a total idiot.
