A single OVA that thinks like a novel. Three stories across four centuries, each one grinding on the same question: what does it mean to stay human when you're the last humans alive? The 80s animation is thin by today's standards, but the ideas move through you like radiation you can't stop. This is what happens when anime takes hard sci-fi seriously instead of using it as window dressing for action.
Two young couples are chosen for the Space Seeding Plan, a project run by the Space Administration in the first half of the 21st century. Adam and Hannah agree to take part of their own free will and are selected after a series of tests of body and mind. Their sperm and eggs are then placed aboard the spacecraft Ozma and sent into the distant universe. Adapted from Yukinobu Hoshino's 1984 science fiction manga, this single-episode OVA from 1987 imagines humanity trying to plant its future among the stars.
