Seiya Kanie, a brilliant but narcissistic high school student, feels that the lovely but quiet Isuzu Sento has asked him out on a date to Amagi Brilliant Park, an amusement park. Not only is the setting a run-down facility, but the alleged date is really a recruitment tour where Sento and the theme park's owner, Princess Latifa Fleuranza, invite him to become the park's new manager. What is the source of their desperation? Amagi has fewer than three months to achieve a quota of 500,000 visitors, as stated in a land-use contract, or the park will be closed permanently and the area renovated by a greedy real-estate corporation.
