Ulysses and the Stars

It is the year 2000. The parents of twelve-year-old Peta are worried about the boy. He has made a flying machine on the model of a bird, but it crashed when he tested it and he broke his arm. His father Misa goes back in his memories to the year 1975, when he was the same age as Peta and also experimented with various inventions. He tells Peta about a stone radiating a blue light which affected the workings of engines and the growth of flowers. One day the stone disappears. Misa finds it on the bottom of an aquarium by which his five-year-old sister Kata sits drawing. The little girl claims that the stone has come from the stars.
