Sourin fights for Ishida Mitsunari against Tokugawa Ieyasu, fighting alongside his retainer Tachibana Muneshige. His signature weapon is a massive tank called "The Head of Xavi," designed to resemble the late Pontiff Xavi. The tank fires cannonballs from its eyes and plays a Xavi hymn during battle.
There's some connection between Sourin and Xavi—a picture exists of the two together on the bridges of memories, suggesting a personal relationship beyond mere religious devotion.
