Asaemon Yoshihiro Yamada (山田 浅右衞門|山田 浅右衛門 吉寛 Yamada Asaemon Yoshihiro?) is a samurai who is a highly skilled swordsman, frequently directed by Burando to dismember Manji for experiments while Manji is sedated and incapacitated. When Rin breaks into the prison to save Manji, she and Doa are confronted by Asaemon in Manji's cell; Asaemon, in turn, is killed by Manji. His liver is later used by Manji as medicine for Makie's tuberculosis, despite her aversion to idea of consuming human liver.
