Muneshige fights alongside his lord, Ōtomo Sōrin the side of Ishida Mitsunari against the forces of Tokugawa Ieyasu. He wields two chainsaws in battle. It is shown that even though his lord Otomo Sorin is a devout follower of Xavism, Muneshige is worried about his fellow warriors as they have all been deluded into becoming part of Xavi's cult. Muneshige doesn't seem to follow Xavism. He is married and seems afraid of his apparently estranged wife, but thinks about her often since she left.
