北斗神拳
Raoh is the eldest of the four adopted children trained by Ryuken, the previous Hokuto Shinken master. The manga gives two different origins through the course of the story. In his first origin, Raoh and his biological younger brother Toki, were adopted by Ryuken after their real parents died. The second (and real) origin shows that a young Raoh and Toki, along with an infant Kenshiro, were actually refugees from the Kingdom of Shura who were sent to Japan to be trained in the art of Hokuto Shinken by Ryuken after their homeland was torn apart by a civil war.
