Gonryoumaru

厳霊丸

Gonryōmaru is the manifested spirit of Choujirou Sasakibe's Zanpakutō, appearing during the anime-exclusive Zanpakutō Rebellion and the subsequent Toujuu Campaign.
He frequently addresses people using the -dono honorific, which translates to lord or master. Additionally, Gonryōmaru harbors resentment toward his former owner for failing to distinguish himself from other Shinigami. Gonryōmaru also appears to share a specific friendship with Tenken, addressing him as Tengen-dono and speaking on behalf of Tenken, who seldom talks.
