"On Your Mark" is a short animated music video directed by Hayao Miyazaki, produced by Studio Ghibli, and set to the song of the same name by the Japanese duo Chage and Aska. The narrative unfolds in a dystopian future where humanity lives in a polluted, post-apocalyptic world. Two police officers, part of a special task force, raid a cult's hideout suspected of harboring dangerous activities. During the operation, they discover a winged girl, an angel-like being, held captive by the cult. The officers rescue her, but their superiors take her into custody for scientific experimentation.

Determined to save the winged girl from exploitation, the two officers devise a plan to break her out of the heavily guarded research facility. Their mission is fraught with tension and danger as they navigate through high-security areas, evade pursuit, and confront the moral implications of their actions. The story emphasizes themes of freedom, sacrifice, and the struggle against oppressive systems. The officers' bond and their shared resolve to protect the innocent girl drive the narrative forward, culminating in a daring escape that blends action and emotional resonance.

The characters are defined by their roles and actions rather than extensive backstories. The two officers are portrayed as determined and compassionate, willing to risk their lives for a cause they believe in. The winged girl, though largely silent, serves as a symbol of hope and purity in a bleak world. The narrative's brevity and visual storytelling allow for a concise yet impactful exploration of its themes, making "On Your Mark" a memorable and thought-provoking work within Studio Ghibli's repertoire.
