The leader of the Shogun's Banshu samurai, the Bangashira, and secret leader of the Mugai-ryu. He simultaneously invites the Itto-ryu to become an official sword school while directing the Mugai-ryu against it. Kagimura also masterminded and took part in the massacre that occurred during a feast welcoming the Itto-ryu into the Banshu. Abayama's comments imply that he is incredibly skilled with a sword, as evidenced by his attack on Manji in Trickster, volume 15. He first appears in Dark Shadows part 1.
