Ryuhaku Todoh (藤堂 竜白, Tōdō Ryūhaku) is a character from the fighting game Art of Fighting and the father of Kasumi Todoh.
Todoh is the creator and main teacher of Todoh style Kobudo, which derives its style from Aiki- jujutsu and Kendo. Todoh had a long standing rivalry with disciples of the Kyokugenryu school of Karate and considers them a threat to his style of teaching in terms of profits as well as personal animosity dating back to a rivalry with Takuma Sakazaki from when both men were very young.
In his quest to find his abducted younger sister, Yuri, Ryo Sakazaki blatantly attacked Todoh at his school and fought him to interrogate him about the whereabouts of his sister. After Ryo easily defeated Todoh, he was humiliated and saw his school's finances as well as the attendance at his schools suffer. It was rumored that he went into hiding as a result of his loss and haven't been seen since, but according to his wife Shizuko, he's been training in another corner of the world for a rematch against Ryo in the near future.
Due to his disappearance, his daughter Kasumi went on a personal quest to not only try to look for her father, but to gain revenge on Ryo and all Kyokugenryu disciples to try to reclaim her family's honor.
In Art of Fighting, very little of Todoh's personality was shown. In later games, he became comic relief for SNK, cheering for Kasumi and often crying when she accomplishes something. But during in one of his cameos he is seen hanging with his friends Duck King and Heavy D!, so it shows that he's carefree sometimes.
