Matsugorou Tenjinbayashi, a scientist with facial hair, operates as the primary antagonist. He engineers schemes for global domination by deploying an army of advanced-technology robots. Two inept assistants, Epsilon and Omega, support his operations by managing the robotic forces. Matsugorou’s drive for technological supremacy fuels his quest for absolute control, pitting him against opposition.

The protagonists combating Matsugorou are three brothers: Ran Tenjinbayashi, Ken Tenjinbayashi, and Takeo Tenjinbayashi. They unite as the Emergency Departure Saver Kids team. Ran employs martial arts expertise and physical prowess in confrontations. Takeo is noted for wearing glasses, though his abilities remain undefined. Ken’s specific traits are unspecified. Together, they pilot specialized aircraft to dismantle Matsugorou’s threats and shield others from his robotic forces.

Umeko Tenjinbayashi exists within the Tenjinbayashi family without a defined role or relationship to the core characters. Seira appears in the series with unspecified connections or relevance to the conflict. Dr. Bug maintains an affiliation to Matsugorou’s operations, though the nature of this alliance and Dr. Bug’s expertise lack detail.
