Type: Sei

Type: Katsujin Ken

Martial Arts: Chinese Kenpo (Chuō Jiǎo)

Shokatsu Kouan is a disciple of Ma Ryou (Hakubi) and the partner of Ryuu Genson. He wears glasses and suspenders, and is the calmer, politer one of the two. While he can be diplomatic, he's just as willing to use force as his partner.

Along with Ryuu, Shokatsu is sent by Hakubi to bring back his grandniece Ma Renka. They end up fighting Kenichi at a water park. During the battle, Shokatsu is caught off guard by Kenichi's leg strength and is knocked down. Afterwards, Shokatsu and Ryuu apologize for their actions and explain the situation, with the friendlier Shokatsu actually praising their strength. Then they leave for Hakubi's place with Renka.

Much later, during the Yami arc, Shokatsu and Ryuu appear as escorts for Renka for her first day at Kouryuu High. They run into a Chinese master, but the help of Takeda Ikki, they easily claim victory.
