I Was Forced to Start Cram-Style Teaching in Another World with a Principal System

(And so I was forced to become the head of the villains)

A college student cramming for final exams casually opens a book during a break from studying all night. The book tells the story of the evil mages who will one day be wiped out by the forces of justice.

Fifteen minutes later, she transmigrates into the role of principal of the magic academy.

"Let's be positive, everyone!" she cries. "Before the school gets a terrible reputation!"

A gloomy, pale girl turns evil after her love goes unrequited?

"Have you finished your exam papers? What are you babbling about?" She slaps her hand down on a lesson plan half a foot thick. "Go on. You can't go home until you've finished this workbook."

A boy of mixed heritage with a tragic past is ridiculed for his strange appearance?

"That's wonderful," she says gently, ruffling his messy hair. "You've improved by thirty points in just two weekly tests. A clever kid like you makes your teacher proud."

But what about that one...

Hey, what's with that potions professor who practically has the word "villain" stamped on his forehead?!

Emmm, considering he's holding a delicious little strawberry cake he made himself...

"All right," she says. "I suppose I can deign to like you a little."
