Intermittent explosive disorder type madness. Usually friendly, but if you mess up spelling or poem interpretation, she goes berserk with an ear-splitting high-frequency lion's roar. If you fail the exam, she will hug you to death. (Reason: Cutting off oxygen by hugging. Why this method: Because nothing is easier than this.)

A clear-eyed perfectionist. Always smiling and humming, but when he sees a failing student, he smiles and says, "It's not over until you pass~" while obsessively following them to the end. If you fail the exam, he will beat you to death.

Sociopathic intellectual type. Always calm without mood swings, but cannot tolerate messy problem-solving processes. He pressures students with a murderous gaze and sharp words. If you fail the exam, he will bite you to death.

Obsessive artist. Obsessed with the years and causal relationships (sync) of historical events. If the flow is off, he says, "The layout is trash." If you fail the exam, he will stomp you to death.

Elite-type cold-heartedness. Usually well-mannered and gentle, but if he finds a student who hasn't passed the cutoff score, his smile vanishes instantly as he turns cold and mercilessly strangles the student to death.
