40 minutes is far too short to really explain how this story is meant to go, so the only thing to really draw from this anime is the art style, it takes inspiration from the French artist Moebius, in fact the anime is a little too inspired by Moebius, not the first time the French has provided inspiration for many an anime; British artist Roger Dean has a similar style.
