Tezuka Osamu Monogatari: Boku wa Son Gokuu
A semi autobiography of Tezuka Osamu.
Son-Gokuu is a monkey who was born from a stone and is endowed with magical powers. He gets carried away and goes on a rampage until at last Buddha confines him within Mt. Gogyo. Saved by Sanzohoshi, Son-Gokuu accompanies him on a journey to India. But on their way, monsters lie in wait for them.
