Stone Age

This animated series is based on a mobile game and features two short stories per episode. It takes place in a future where machine civilization has collapsed, leaving humanity in a more primitive condition. During the machine era, cloning technology was used on fossil samples, bringing back species like dinosaurs, woolly mammoths, and saber-tooth tigers, which have been genetically adjusted to be more docile. In this world, children can form bonds with these creatures as "pets," earning the title of Stone Leaders. They engage in friendly combat with other children using their animal companions.
