Hideo Masaka was a member of the Orphic Circle and a potential Orgiophontes candidate of the cult's inner circle. His surgical theater was situated in the south wing of their headquarters. He watched his mother drown in a hydrotherapy "accident", since which time he has worn white suits (the traditional Japanese colour of mourning).
In 2000, Masaka began posting on hunter-net as an anonymous user. He requested others refer to him as Ichmail. He offered the Imbued significant intelligence on the Orphic Circle, vampires, and other topics related to the undead. His posts are included in the /walkingdead/ archives on hunter-net.
