A 17-year-old girl named Suzume resides in a peaceful municipality in Kyushu. She sets forth on a voyage and coincidentally meets a young man who seeks an entrance. Collaboratively, they uncover a dilapidated gateway situated in the mountains, and Suzume unlocks it. This initiates the activation of other portals throughout Japan, releasing calamities of an enigmatic realm. As Suzume begins to grasp the state of affairs, she transforms and releases herself from previous limitations. Her goal is to shut the gates that cause havoc, eventually resulting in her own enlightenment.
