Nothing particularly interesting to see here - just another in the long line of story ideas that came from the mind of Leiji Matsumoto, and there is not anything in this little short that we haven't seen him do before. You have the potato-headed naive boy (one of Matsumoto's stock characters), you have the gentle willowy tall female with long hair (the second Matsumoto stock character), plus add an android man to the mix. The three of them head off to the very edge of the universe to explore beyond, until they reach the gate and are basically told "Nope!You are too war-like!". (Not so much a spoiler, because there's more after that).
More or less, this is yet another vehicle for Matsumoto to bang our heads about for being cruel, bad, awful human beings that battle and kill each other -- a theme that he harps on a lot. Yeah, we get it already. If he could get beyond that mental story roadblock of his, maybe an interesting story could be the result. This isn't it.
Oh, and there's also some gnarly 1980's computer graphic animation, too. Just to show what as "state of the art" for computer animation at the time.
