Movie
Description
Jō Kurumada serves as the Chief Engineer of the Mobile Rescue Police, holding the vital responsibility of developing, maintaining, and deploying the series' central Drive Head rescue robots. He inherited the Drive Head project from his late father, Joutarou Kurumada, the original creator of the Drive Gear technology. His professional role is not confined to a laboratory, as he frequently demonstrates significant athleticism and a willingness to engage in field operations, once boarding a virus-infected crane ship and scaling a mountain to manually relay an emergency signal during a dam crisis.

His personality is a blend of passionate enthusiasm and a quick, decisive nature, particularly when a mission is underway. Despite being a brilliant strategist and engineer, he can be notably absent-minded, especially regarding personal matters and social details. This workaholic tendency is a core aspect of his character, as he is deeply dedicated to his job, sometimes to the detriment of his family life. This is best illustrated by an incident where he became so preoccupied with work that he completely forgot a phone conversation with his wife, leading him to mistakenly believe she had left him when her absence was simply a pre-planned vacation. His love for his family, particularly his wife Kumiko and son Gou, is immense and openly displayed; his public affection with Kumiko is often described as exceptionally sweet, much to their son's embarrassment.

Jō's motivations are driven by a powerful sense of responsibility towards his team, the protection of the public, and the safety of his family, frequently expressing concern when his son Gou engages in dangerous rescue missions. He is also motivated by a desire to uphold the legacy of his father's work. A unique and significant personal hobby is his annual tradition of traveling to watch dam drainage tests, an event he approaches with unparalleled excitement.

Within the story, Jō acts as a central pillar of the Mobile Rescue Police. He enjoys a long-standing, collaborative friendship with Commander Takahito Saionji, which dates back to their school days. He also directly supervises the mechanics Hayato Isurugi and Toshimichi Izawa, whom he occasionally teases in a good-natured way. His most complex and pivotal relationship is with the antagonist, Dr. Karigari. They were former colleagues in disaster-control robotics, but Jō pointed out critical safety flaws in Karigari's project, leading to its rejection in favor of the Drive Head initiative. This rejection festered into a deep grudge, with Karigari seeking revenge. Despite their adversarial dynamic, Jō possesses a grudging respect for Karigari's intellect and even shows concern for his well-being when Karigari is gravely injured by a greater threat, the Evil AI.

Jō undergoes significant development throughout the series, particularly in reconciling his work-life balance. His initial role is purely technical and strategic, but he gradually becomes more actively involved in frontline rescues, eventually piloting the Transporter Gaia support vehicle himself in later missions. Facing the sentient Evil AI forces him to confront his past, as it leads to the discovery that the AI robot Pit contains a digital copy of his father's consciousness, which provides crucial insights for defeating the threat. His relationship with Dr. Karigari also evolves from pure hostility to reluctant cooperation, with Jō requesting and thanking Karigari for his assistance in combating the Evil AI, even though Karigari refuses to fully mend fences.

Notable abilities include his engineering genius, which led to the creation of the original Sonic Interceptor. After that unit was severely damaged, he spearheaded the development of its more powerful successor, the Cyclone Interceptor. He also contributed to developing the Transporter Gaia. Beyond design, his strategic acumen is a vital asset, proven when he orchestrated the manual launch of Drive Heads after the Evil AI hijacked the Mobile Rescue Police headquarters' systems. His on-foot athleticism and physical courage are also notable, as seen during the dam crisis and the Fugaku ship incident.
