Gonry�maru is the manifested spirit of Ch�jir� Sasakibe's Zanpakut� that is seen during the anime-exclusive Zanpakut� Rebellion and subsequent T�jū Campaign. He often refers to people by the -dono honorific, which means lord or master. Also, Gonry�maru resents his former owner's inability to stand out from other Shinigami. Gonry�maru also seems to have a particular friendship with Tenken, calling him Tengen-dono, and speaking for Tenken, who rarely talks. (Source: Bleach Wiki)
