Osu (1987)

In a convenient world where vending machines offer just about everything, the hero procures whatever he needs from machines on his journey to see the creator. He tries to make a replacement purchase of the earth. But the creator declines his request, saying simply that there is no such thing as a brand new earth. The simplicity of the story illustrates the depths of Tezuka Osamu's despair at earths degradation, forming the gist of this 4 minute work.
