Can Opener Mask's mission was to investigate an EAGLE base which was developing a new mold to be used in a weapon known as "Kabika X", which would have the ability to destroy any mechanical device by merely being mixed with oil. Kumano was in charge of stopping any Black Cross invasion of the lab, but Can Opener Mask and the Zolder ninjas sneak by eluding them and allowing for them to take the mold and use it to destroy the machines and vehicles of Japanese society. Kumano wants to initially stop them, but can't due to Shinmei grounding the entire Gorengers' fleet out of fear of their destruction via the mold mixing with their fluids. However after Taro becomes severely hurt by a runaway car struck by Kabika X, Kirenger decides to do something about it.
