Seiya Kanie, a clever and highly narcissistic high school student, assumes that the attractive yet reserved Isuzu Sento has invited him to a date at Amagi Brilliant Park, an amusement park. To his dismay, the venue is not only a dilapidated facility, but the alleged date is actually a recruitment tour where Sento and Princess Latifa Fleuranza, the park's owner, request that he become the new manager. The reason for their desperation? According to a land-use contract, Amagi has less than three months to reach a quota of 500,000 guests, or the park will be permanently closed and the land redeveloped by a greedy real-estate company. Seiya is convinced by the revelation that Amagi is no ordinary amusement park; many of its employees are Maple Landers—mysterious magical beings who reside in the human world and are sustained by the energy generated by people having fun. Entrusted with the hopes and dreams of this distant enchanted land, Seiya must now use his various skills to restore Amagi to prosperity, or watch it crumble before his eyes.
