Modern Day Japan. A top class negotiator fresh from resolving and internal land dispute is about to take a flight when a giant cube lands upon them, drawing him and the rest of the plane's passengers inside.
Inside, Shindo meets the cube's owner, a transdimensional being that refers to himself as a visitor from the anisotropic. A higher level dimensional plane, he has gained an interest in humanity and claims to wish to advance humanity's technological evolution.
A lot of great philosophical and political questions are asked. When an unlimited energy device is gifted, what nations on Earth should be granted access to a limited number of devices? What would be the economic fallout with fossil fuels and alternatives becoming obsolete? What about the risk involved in transferring all our energy control over to an alien power supply we don't understand?
The questions become more complex as the anisotropic being provides a new technology that expands human consciousness to the point that people no-longer need sleep. What are the risks in changing human consciousness and fundamentally changing who we are even if, all tests show there are zero drawbacks? How will companies exploit this when the work culture in Japan already works people to death.
The question really is, how do we deal with the advancement of our species by an outside force who's motivations we do not really understand? What is the right answer.
Well it's this: (spoilers)
When the Transdimensional being suddenly changes character to a crazy man that wants to draw you into his dimension which may kill all mankind, have sex with another transdimensional being to create a hybrid super-girl rapidly aged to 16 using a time dilation device so she can defeat the bad guy with her magical powers.
Damnit Japan. You were so close! It's as if you couldn't expunge all the anime cliches from the show, so you just pushed them into the last part of the series and hoped no-one would notice.
