The Sket-dan is having fun trying to take their minds off the upcoming midterms, when they hear rumors of a mysterious DVD that will curse you with bad luck if you watch it. Just then, Kuramoto Ayumi comes in with a simple request, to help cheer up her friend who has been acting strange lately. But there's more to this than meets the eye, as the stoic Yagi is acting like someone who has seen something they shouldn't have...

¡Pero si no había nada en 
el DVD seríamos expulsados!
¡Pero si no había nada en 
el DVD hubiésemos sido expulsados!
Eu teria sido expulsa se
 não tivesse nada no DVD!
