Summer 1964 Anime

Three episodes from the Astro Boy television series—"Robot Rocket" (episode 46), "Earth Defense Troops" (episode 56), and "The Last Day of Earth" (episode 71)—were selected and re-edited for a theatrical release. Among these, only "Earth Defense Troops" originally came from Tezuka Osamu's story "Number 7," with its settings later adapted into the Astro Boy series. For this film, the entirety of "Earth Defense Troops" and a portion of "The Last Day of Earth" were reproduced in color specifically for this theater version.

This is a straightforward tale of a boy mastering the arts of ninjutsu, battling evil forces, and searching for his mother. Young Fujimaru was snatched from his mother by an eagle but was rescued and raised by a ninja named Sasuke, who taught him ninja techniques. Later, Fujimaru sets out on a quest to find his mother, where he confronts his archenemy and discovers a secret book containing hidden ninja arts. Although the series is quite old, it showcases numerous classic ninja techniques, including elemental manipulation of fire and wind, creating illusionary clones, and breathing through a reed.

After being kidnapped and later saved by a Ninja, Fujimaru spent many years perfecting his martial arts. He now embarks on a mission to find his mother while simultaneously searching for an old scroll that contains secret martial arts knowledge.
