A 1975 Sci-Fi Shoujo Manga originally written by Moto Hagio, with an anime adaptation released in 1986.It is the future. Earth, now known as Terra, has made contact with various other planetary civilizations, and formulated one central school for the cream of the crop. Beings from around the known universe gather to take the entry examination; the test is hard, but it's said that admission guarantees an influential position after graduation, and the riches of the universe are theirs for the taking. Ten young space cadets are put onto a decommissioned spaceship in orbit around a small star as the final part of the test.Their orders are simply to survive as long as they can with what they have. There is an emergency beacon that they can activate to be rescued, but the implications for their score on the exam are obvious. However, once they arrive at the decommissioned ship, they find that their crew has mysteriously gained an eleventh member. And then things start going wrong...As the days pass, the eleven cadets, each from different cultures, species, and walks of life, must deal with their suspicions of each other as well as the sudden knowledge that the orbit of the spaceship is gradually decaying, rising the on-board temperature as it gets closer and closer to the star. With this rise in temperature, a mysterious sickness begins to spread among the crew as they work to stabilize their orbit and determine who among them is the spy.
They Were Eleven shows examples of the following tropes:
- Accent Adaptation: Frol's coarse and straightforward method o' speakin' is translated in the dub as a Dixie accent.
- Artistic License - Physics: Orbits about a single star (or other massive object) don't decay, except possibly unnoticeably slowly (as on the order of centimeters per million years — except for binary neutron stars).
- Those could be some really powerful Explosion Propulsion, Inertial Damping and construction materials.
- Or All part of the Secret Test of Character
- No, but the ship coulb be 'knocked' from a round orbit to an elliptic one due to speed loss (caused by a leak maybe?) . Although the presence of the planet should attract the ship instead, unless the ship is on the edge of the gravitational influence of the planet vs. The blue star...
- Bokukko: Even though Frol considers himself a man, he generally comes across as one of these.
- Friend or Idol Decision: Frol catches the sickness after the students save the ship. Despite Frol's desperate pleas, everyone else agrees to activate the beacon, sacrificing the test and their own dreams to save his life.
- Hermaphrodite: Frol — his species is asexual until adulthood, when gender is determined; traditionally, only the firstborn of a family is made male, and the others female. However, if Frol gained admission into the Cosmo Academy he would be allowed to pick his own gender, which is why he's here. Knu delivers the exposition because his species is similar.
- I Lied: The Big Red Button is supposedly a full forfeit, and will cause everyone to fail the exam. In reality it's fully expected for the test-takers to press the button; they are actually graded on how long it takes them to reach that point, and how they dealt with each crisis that evolve.
- Samus Is a Girl: Played with. The other students react this way the first time they see Frol out of his spacesuit, until he corrects them. Later, when another student sees Frol in the shower and notices that he's missing something important, most of the other students conclude that Frol's pulling a Sweet Polly Oliver until Knu makes The Reveal.
- Secret Test of Character: Beside the obvious test of ingenuity and survival skills, the exam tests how well would-be students can handle pressure with no outside support. The eleventh examinee is actually a supervisor: he throws everything off-balance right away and performs sabotage throughoutm to pressure the team to press the button. Of course some of the things that go haywire weren't part of the test but the cadets get extra points for those.
- Ten Little Murder Victims: Subverted. No one ends up dying.
- Training Accident: The vine-sickness was not part of the test. It only happened because one of the explosive charges the crew had to disable at the beginning of the test went off and knocked the ship out of orbit; it then got close enough to the system's sun for the vines to start growing again.
- "Where Are They Now?": In the anime movie adaptation, done in the style made iconic by American Graffiti.
