Eiku Shizuma
Immortal swordsman. Gifted with the same blood-worms as Manji, he seeks to gain Manji as an ally to overthrow Anotsu. He said in Cry of the Worm that the kessen-chu were given to him by Yaobikuni during the Muromachi period, which means he is two hundred years old. His weapons are a poisoned pair of a dagger and a saber both named Inoue Shinkai Kosatsu ("Wormkiller"). He first appears in Conquest part 1, is named in Cry of the Worm part 1 and is later killed by Manji in Cry of the Worm part 3. The poison he uses (Kessen Satsu) is later used in Trickster in an attempt to kill Manji.
