An alien sent to destroy Earth falls in love with it instead. Seventy-six years later, his own people send an assassin to finish the job. This is Tezuka's first OVA, and it swings for something genuinely strange: a science fiction premise that treats planetary beauty as a reason to betray your entire civilization. The story collapses under its own ambition and the runtime can't contain what it's trying to say. For completionists and historical obsessives, it's required viewing. For everyone else, it's a fascinating failure that proves even Tezuka couldn't make a one-episode Terminator work.
An agent rides Halley's Comet to Earth under orders to destroy the planet, but the world's beauty leaves the agent unable to go through with it. Seventy-six years later, a second agent arrives from the comet to eliminate the traitor. The newcomer takes over the body of an escaped murderer in the Nevada desert, then heads for Vietnam, where the first agent lives in the form of a girl called Lamina. Meanwhile, microbiologist Subaru Marita joins a research team bound for Vietnam to study a newly discovered microorganism. His father Robert met Lamina, a mysterious woman with healing powers, in the jungle during the Vietnam War and was separated from her by the fighting. Robert gives Subaru an old harmonica to pass on to her. Subaru finds Lamina, who has not aged since those days, and is drawn into a mystery far larger than his research. The single-episode science fiction and fantasy OVA was the first original video animation made by Tezuka Productions, drawing on an original story by Osamu Tezuka.
