During the Taisho Period (Early 1920's), a monastery of warrior monks was split apart between two factions. One of these factions was led by the Chief Abbot and his prot g, Shinkai. When Shinkai intercedes in a fight between a rival priest and some ruffians, it leads to hes expulsion from the order. This story introduced us to the character of Shinkai, a Karate Priest and his long running feud with Ryotatsu, his greatest rival. There are touches of humor ans Shinkai breaks all the commandments of a priest, including fighting, gambling, and running after women. All this leads to an awesome conclusion as he must destroy a gang of yakuza aided by corrupt priests. The fighting is fast and furious as Ryotatsu wants to see if Shinkai can live long enough to face him in the ultimate test.
