While the title suggests a story of simple, everyday school life, the contents are more the opposite. The setting is a strange school where you may see the principal wrestle a deer or a robot's arm hide a rollcake. However there are still normal stories, like making a card castle or taking a test you didn't study for.

Follow the adventures of three ordinary girls as they make life’s awkward moments a thousand times worse. Along with a colorful bunch of classmates, they learn their most important lessons the hard way. Like whether goats are an appropriate form of transportation, who would win in a wrestling match between the principal and a deer, and most notably, if the three-second rule applies to weenies that fly through mohawks. Meanwhile down the street, a pocket-sized professor makes life difficult for a robot who just wants to be normal. But normal is the last thing you can expect in a town where salmon falls from the sky. In fact, the only thing you can count on is your friends, but even they are totally weird.
