Paniponi Dash
Volume 6

After being dragged into a student puppet theatre, the young genius teacher Becky finds real drama when the principal storms her research room. What does he tell her? That a giant comet is headed straight for Earth - and she and her class of crazies have to save the planet!

But before they can get 'round to that, it's time for a blast from the past. Actually, to the past, where Becky is an evil politician trying to avoid 1-C going samurai assassin on her butt after she imposes a tax on tears (which, when you're teens stuck in the feudal era with Becky, are bound to fall often).
