head due to having two spines. A daytime airstrike fails to neutralize Gyaos due to its ray. Meanwhile, Gamera recovers from its wounds beneath the sea. During a meeting, the villagers become divided on whether to sell their land or not due to Gyaos. Shiro's crew, save two, quit because of Gyaos. Despite Eiichi's claims that Gyaos is nocturnal, Gyaos ignores military flares and attacks Nagoya. Gamera appears and battles Gyaos once more, biting off its toes in the process. Dr. Aoki discovers that exposure to ultraviolet light, like the sun, causes the toes to shrink. A plan is formed to disorient Gyaos long enough for the sun to rise and kill it, using artificial blood as bait. Gyaos is lured out but the plan fails when the power station overheats. After learning that the expressway would be rerouted due to Gyaos, the villagers blame the headmaster, who ordered them to hold out. The headmaster regales a plan to Shiro, inspired by Eiichi, to start a forest fire to kill Gyaos. Gyaos depletes the fire with a yellow vapor, however, the fire attracts Gamera and engages Gyaos in a final showdown. Gamera kills Gyaos by dragging it into Mt. Fuji's crater. As the authorities celebrate, Shiro affirms to the villagers that work on the expressway will resume. Eiichi bids farewell to Gamera as it flies away.

When Naoyuki Abe was cast, many mistook him as Yuasa's son. A real office in Akasaka, Tokyo was used
