Schoolgirl Valerie under suspicion

This school is not normal! Nobody wants to go in there, not even Martin. No matter what you do, teachers only know the notes and the only grade - an F. But when Valerie the janitor shows up, suddenly everything is different. It seems that the cheerful beauty with the tattooed bat on her wrist is not in this impossible 5th grade school by accident.
