Starting January 21, 2027, the stage play Tensei shita Dai Seijo wa, Seijo de Aru Koto wo Hita Kakusu — subtitled Knight Order Entry Arc — will run at Theater 1010 in Tokyo through January 24.
Seven performances are planned. Ticket pricing and sales information will be announced in August 2026, with key visuals, an official website, and early ticket sales opening in September 2026 or later. Additional cast members will also be revealed in August.
The stage play adapts the light novel series that has sold over 4 million copies cumulatively. The story follows Fier, a girl without sword talent who becomes a knight while hiding her true identity as a reincarnated holy lady from 300 years ago. She meets fellow knights Cyril and Savvis upon joining the order. A TV anime adaptation is scheduled to debut in October 2026.
Director Ise Naohiro, known for stage adaptations of Tokyo Revengers, Blue Lock, and That Time I Got Reincarnated as a Slime, helms this production. The confirmed cast includes Honishi Akiho as Fier, Komatsu Junya as Cyril, and Isaka Ikumi as Savvis.
AniHeat's take: Worth noting for light novel and manga fans, as this stage play offers a theatrical interpretation of the story alongside the upcoming anime adaptation.
