Olga Janetine is a supporting character in Gunslinger Stratos: The Animation, where she appears as a freelance operative involved in the conflict between parallel worlds. Her real name is Orika Rindou, and she originates from the Rindou clan, a family she abandoned after breaking its rules. Following her departure, she established herself as an independent agent working in the underworld, where she gained a reputation as an expert in sniping and the use of explosives.

In terms of personality, Olga is narcissistic and possesses strongly sadistic tendencies. She tends to mistreat those she finds cute, and her current focus is her younger sister, Shizune Rindou, who despises her as a disgrace to the clan. Olga carries herself as a dangerous, provocative older woman, frequently making suggestive remarks, and her temperament becomes noticeably more volatile when she is excited.

Her motivation within the story centers on a specific mission: she volunteers for the Second Time-Space Transgression Operation in order to secure Remy Odhner and bring her back to the present. Later installments of the franchise reveal that she works under a patron who hired her, adding depth to her otherwise freelance status. She also has personal history with several other characters, including being responsible for taking the legs of Lyudmila, and Aaron Burroughs describes her as a flower blooming on the battlefield.

Within the anime, Olga functions as a supporting figure rather than a central protagonist, and her actions are tied to the time-space operations that drive the narrative. Her role emphasizes her ruthlessness as an operative and her complicated entanglement with the Rindou family, particularly the unresolved hostility between her and her sister.
