The creature, who takes on the moniker “Koro-sensei,” offers them an unbelievable deal — if they can assassinate him before graduation, he’ll spare the planet. This special episode offers a thrilling glimpse into the absurd yet high-stakes world of Class 3-E. Witness their initial, often comical, attempts to take down their nigh-invincible teacher.
