Flint: The Time Detective

In the 25th century, the dark lord has corrupted history by planting time-devices that threaten to destroy the past irreparably. Genshi and his father lived in prehistoric times until they were turned into fossils. When they are discovered, Genshi is restored to his original form. With the help of his father, a boy named Tony, and a girl named Sara, he must journey through time to retrieve the time-devices and return them to the land of time-before history is lost forever.
