For ten-year-old teacher Negi Springfield and his all-girl class, it's time for final exams! If his students manage not to end up with the lowest scores in school, the principal has promised to make Negi an official teacher. To prepare for the tests, the class takes a trip to the school's Library Island. But this is no quiet place to study...stone golems, traps, and secret passageways are the norm throughout the enormous library building. With all of these distractions, can Negi's class hope to climb out of the cellar--both academically and literally?
