Kōan Shokatsu/History

==Ragnarök Saga==
Along with fellow disciple Genson Ryū, Shokatsu is sent by Hakubi to bring back his grandniece Renka Ma. They end up fighting Kenichi Shirahama at a waterpark. During the battle, Shokatsu is caught off guard by Kenichi's leg strength and is knocked down. Afterwards, Shokatsu and Ryū 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 Ryū appear as escorts for Renka for her first day at Kouryu High. They run into a Chinese master, but the help of Ikki Takeda, they easily claim victory.
