Seiya Kanie -- handsome, scholastically successful and athletic, self-confessed narcissist Seiya Kanie is befuddled. His classmate, Isuzu Sento, gives him a musket and asks him out on a date.

Amagi Brilliant Park is operated by the residents of magic nation of Maple Land. It seems like a fantasy, but having been given the ability to hear people's minds by its owner, Queen Latifah, Seiya has no choice but to believe it.

Circumstances and impulse bring Seiya in the position to become the acting owner. He proposes reforms in order to meet the goal of attracting 250,000 visitors within three months, but the crew is full of complaints.
