20001-nen Chikyuu no Tabi

Captain Kepo, the curious Alcia and their inexperienced companion Rigel arrive on a planet whose former inhabitants are gone. Strange remnants of an advanced civilization are all they have to work with as they try to understand its vanished people.

For these visitors, the place is an alien mystery. It is also Earth, and the traces humanity left behind may look very different through unfamiliar eyes.
