I'm looking for the title of an anime, possibly from 1990.
It's about a group of pilots from various planets on their final test. The first complication is that there is one extra pilot among them. Second, the ship they boarded is losing trajectory, and because of this it is overheating, causing vines used as electricity cable to grow and emit toxic spores. The only known vaccine is made from mice that lived on the ship. One of the pilots is a survivor of the original outbreak that caused the ship to be abandoned in the first place. Another one of the pilots is transgender. They team up to save the ship.
That's all I remember. Thanks.
