(from ebookjapan):

Some 3,500 years ago, the Arians living on the banks of the Indus River had established a caste system with Brahmins at the top. Shortly before the birth of Siddhartha, the hero of this story, Chapra, who was born a slave, became his adopted son after helping a general of the Kosala kingdom.

He then hid his origins and sought the position of power, but Chapra, too, could not escape the curse of the status system...

Here begins the epic story of the Buddha's life and the times in which he lived!

The complete biography of Buddha, as seen by Osamu Tezuka.
