I became a professor in a game by accident. To make matters worse, I even messed up the difficulty settings. Now, I’m stuck playing on Hell Mode. A world on the brink of war with the Demon King. An Assassin Department where mu*der is legal… as long as you aren’t caught. I thought I’d have to claw my way through just to survive in this wretched place, and that was the case at first. But nowadays… “No matter how hard I try, I can’t be like you, Professor… How do you do it?” “Please… become our god.” “What do you know? What is it you know? Why do you make me want to live…?” One by one, everyone at the academy began to obsess over me.
