Seiya Kanie, a handsome, scholastically successful and athletic high school student, freaks out when his classmate, Isuzu Sento, points a musket at him and demands he take her on a date to an amusement park.

Seiya must accept the reality of his situation after learning that residents of the magic nation of Maple Land operate the park and receiving the ability to hear people's minds by its owner, Queen Latifah.

Circumstances land Seiya the position of acting owner for the park; he proposes reforms to meet the goal of attracting 250,000 visitors within three months, but the crew has a lot of complaints.

Though arrogant, Seiya solves problem after problem at the park; Isuzu wants to be happy about it, but something bothers her.

With the 30-yen offer, the number of visitors slowly improves, but money remains an issue; attempting to find quick cash, Seiya visits Moffle, and they set off to search for a supposed treasure hidden in a cave.

Isuzu has mixed feelings about Seiya's expert handling of the issues at the park, even having nightmares about her own work; she resolves to fix the labor shortage by interviewing potential hires.
