Jun Hono works as an aide at the Photon Power Laboratory in the Mazinkaiser continuity. Her background before the series remains largely unspecified, but she maintains a close association with Tetsuya Tsurugi, consistently accompanying him. Physically, this version retains the darker skin tone of her Great Mazinger anime counterpart but features green eyes instead of brown.

Her personality is mild-mannered and supportive towards the lab's pilots and scientists. She shows significant concern for Tetsuya's safety during combat, suggesting deeper personal feelings. While not a frontline pilot here, she operates effectively as a combat support operator, capably utilizing the laboratory's tools and mechanisms to contribute strategically.

Witnessing the initial attacks by Dr. Hell's Mechanical Beasts firsthand, she sees the destruction and Koji Kabuto's ejection from Mazinger Z. When the lab comes under direct assault, she activates the Photon Barrier defense system. She displays visible anxiety when Tetsuya deploys in a damaged Great Mazinger against scientific staff objections. After Great Mazinger sustains further damage battling the Ashura Mazinger and the newly appeared Mazinkaiser, she departs with Tetsuya. This departure allows Tetsuya to recover from his injuries and enables their search for Great Mazinger repairs.

They return during Dr. Hell's climactic assault involving Ghost Mechanical Beasts. At this critical juncture, she coordinates the evacuation of laboratory personnel and civilians into a concealed control center for safety. From this secure location, she maintains communication with Tetsuya during the final battle and witnesses the decisive victory over the enemy forces.
