Taiyouden

In the era of hunting with spears made of wood and stone tools, one tribe's talented young people were killed while fighting over their prey with "ape-men". Since they worshipped the Sun God, they awaited the arrival of the son of the Sun God, a young man who'd have a cross-shaped star on his forehead and who would one day take them to the "Land of the Rising Sun." One day, as in the prophecy, a boy appears.
