Galaxy Investigation 2100: Border Planet: Tezuka Osamu crafts a love story in the time when humans are expanding into space at the end of the 21st century, employing an omnibus form similar to Bradbury's "Martian Chronicle." Leaving the earth after marriage, a woman is left behind in space when her husband suddenly dies of a cosmic disease. Her friends on the Earth head for space to save the woman who was once everyone's ideal lady. Tezuka Osamu emphasizes his concepts that "love can save the earth" and "only love can save humans."
