The character Rie Saito in the anime "Office Affairs" lacks documented background, storylines, or development across official media. The name surfaces in unrelated instances: a Nihonga artist Rie Saito discusses her painting techniques and exhibition themes; a deaf hostess Rie Saito features in the film *Hitsudan Hostess*, adapted from an autobiography; and a voice actor Rie Saito appears in credits for other productions without links to "Office Affairs". References to "Office Affairs" note its release timeframe and English cast listings, but omit specifics about Rie Saito's role.
