Seiya Kanie is een eerstejaars student aan de Amagi High School. Een nieuwe student, Isuzu Sento, neemt hem mee naar een vervallen pretpark en onthult haar bedoelingen: ze wil dat hij de nieuwe directeur wordt met één doel, het redden van een faillissement vóór 31 juli. Het is een ontmoedigende taak die Seiya te wachten staat, want de attracties zijn in verval en de parkmedewerkers vormen een echte club van gebroken armen, een mascotte die met de bezoekers bokst, iemand die iedereen lastigvalt wat op een vrouw lijkt of een zangeres die vals zingt.
