Ryu Kumon's father



One day Ryu Kumon's father had an encounter with Genma Saotome. After Genma found out about the Kumons' financial problems, he gave Ryu's father a scroll containing the deadly secret art of Yamasenken, a.k.a. Fist of One Thousand Mountains. This led Ryu's father to believe he could use the Yamasenken to restore his dojo, but when he used the technique he ended up destroying it, causing it to fall on top of him which led to his death. With his last moments of life he gave Ryu the scroll and told him to find the scroll containing the companion Umisenken.

Abilities
Before his death he had mastered three moves of the Yamasenken style:


 * Dokuja Tanketsu Shou (Japanese for Poisonous Serpent Searching Hole Palm): Fierce open palm snake strike to the chest area.
 * Kaichü Houju Satsu (Japanese for Jewel Held in One's Pocket Kill): Armlocked Bearhug submission maneuver while holding one arm behind the back.
 * Mouko Kaimon Ha (Japanese for Fierce Tiger Opening Gate Defeat): Deliver a powerful kick through the opponent's guard by separating their arms.
