What's worse than having a sick teacher? Having your sick teacher be a really cranky 11-year old, that's what. When the sick bug quarantines the whole school, both temperatures and tempers are rising to dangerously hilarious health levels. Things get even weirder when Ichijo electrocutes Himeko, turning her into a world-conquering maniac, while the Drama Club and the Film Club finally come to blows in their longstanding war against each other.
Later, when Becky doesn't show up for school, the girls decide to draft an imposter to replace her so she doesn't get in trouble with the most terrifying presence at the school: the dreaded PTA!
