Dragon Ball Z: Doragon bôru Z - Kami to Kami2013

Shenlong:
The Super Saiyan God was formed in response to the darkness in your fellow Saiyan comrades. It was a messiah of Saiyans with good morals, which was rare. This messiah quickly defeated the dark-hearted Saiyans with incredible strength, but he used up all his strength and returned to his normal mode... with a few Saiyans left. Later, Planet Vegeta became a place filled with evil Saiyans, and the savior vanished into legends. If five good-hearted Saiyans hold hands and transfer the light from their hearts to a Saiyan, that Saiyan will become the Super Saiyan God!
