Korashime

Professor Kayama is a university instructor despised by his students, and the feeling is mutual. Miki Watase, a cunning and ambitious student, will stop at nothing to improve her grades. When the professor refuses to play along with her schemes, she vows revenge. Miki gathers her friends: the seductive Hinata, the promiscuous Arisa, and the shy Sachie. Together, they concoct a plan to drug the professor's drink and photograph him in a compromising position, intending to publicly humiliate him.

But the professor is not as weak as they assume. Pushed beyond his limits, Kayama decides to turn the tables on his tormentors. He will teach them a harsh lesson in humility, forcing each of them to confront the consequences of their actions. The students soon discover that their prank has unleashed a side of their professor they never expected.
