Ryou Ma

* First appearance: Battle 66 * Type: Sei * Type: Katsujin Ken * Martial Arts: Chinese Kenpo Ma Ryou, better known as Uncle Hakubi, is the elderly uncle of Kensei and Sougetsu, the grand uncle of Renka, and a master of Chinese martial arts who raised Ryuu Genson and Shokatsu Kouan as his disciples. He is said to be Yokohama Chinatown's most knowledgeable person. Like his younger nephew Kensei, Hakubi is a balding old man with a mustache, who wears traditional Chinese clothes. Unlike his younger nephew, Hakubi also wears glasses and has a black beard. Hakubi is a kind old man who stays on good relations with his younger nephew Kensei and takes care of his grand niece Renka.

This bond with Renka may be extravagant, however, as he is tricked into spilling Ryozanpaku's location with sake by his grand niece, and upon learning of her disappearance, drinks himself to sorrow and takes out the Chinese Mafia residing in Yokohama in a drunken rage. His relations with his disciples are unknown, but he seems to trust them enough to let them go to search for Renka and bring her back. In this, he also adds that he considers Ryozanpaku a strange place and warns his disciples to be careful. His abilities at the Chinese Kenpo are unknown, but he seems to have expertise of the Seven Stars Praying Mantis (Qixing Tanglang Quan) and the Piercing Foot (Chuo Jiao) Styles.

His mastery is so powerful that he is able to take out the entire Chinese Mafia in Yokohama Chinatown. It should also be noted that he did this while drinking heavily.
