Seiya walks into a dying theme park run by magical beings who are actively rude to him, and the show never stops being funny about how completely absurd his job actually is. KyoAni animates every pratfall and deadpan reaction like it matters, which makes the comedy land harder than it has any right to. The romance subplot fizzles out by the end, but by then you're too invested in watching this guy actually fix a broken park full of people who resent him to care.
Seiya Kanie gets taken to Amagi Brilliant Park at gunpoint by a girl who claims she needs his help saving it. He thinks she's delusional until he discovers the truth: the park isn't just struggling financially. The creatures running it are real magical beings who feed on human happiness, and they're starving. Without 250,000 visitors in the next three months, they lose everything. Suddenly drafted as the park's new manager, Seiya has to figure out how to turn a crumbling, half-empty theme park into a destination that draws crowds. His only tools are a ragtag staff of magical creatures with terrible people skills, outdated attractions, and his own natural charm. What should be impossible becomes weirdly personal when he realizes these aren't just jobs on the line: they're lives, homes, and dreams. Between scheming to improve attendance and learning why Isuzu dragged him into this mess, Seiya discovers that saving the park means believing in something bigger than himself. Comedy and heart blend as an unlikely team works toward an absurd but genuine goal.
