Class 789 is the worst class in Shinzo middle school. Any teacher who tries to teach this horrible class is met with desks being thrown around, to text books being set on fire to an explosion caused by an experiment gone wrong.
One day, a 30/30 was called, resulting in everyone getting stuck in class, along with the poor teacher who currently teaching the class. What will happen when the teacher suddenly snaps and runs out of the class, leaving the kids at school by themselves for a whole weekend?
