In 1959, just moments before Typhoon Vera makes landfall at the Port of Nagoya, 12-year-old Asa Asada frantically seeks help from a local obstetrician to help deliver her mother's twelfth child.
When Kasuga realizes his mistake, he regrets his actions, blaming his hard luck after returning from World War II as bomber pilot.
He protects Asa from the storm's damage, and the pair work together to distribute food to flood victims by flying a stolen airplane.
Kasuga is visited by Colonel Shissoji, a former military commander, who shows him a recent photo of the same monster they encountered years earlier.
Colonel Shissoji gives Asa and Kasuga a secret mission to protect the opening ceremonies of the 1964 Olympic Games by converting their aircraft into a makeshift fighter plane.
Restaurant owner Kinuyo, now acting as the remaining Asada children's adoptive mother, defends them against local bullies when the youngest child, Koshichi, claims to remember seeing the monster even though he was less than a day old during the typhoon.
The agent and Eisaku team together to change Yoneko's image to resemble to Marilyn Monroe, but she rejects their efforts and returns home.
Following the opening ceremonies, Colonel Shissoji enlists Asa and Kasuga to stay on call in case of another monster attack.
Young SDF Lieutenant Kosugi suspects the government is covering up a kaiju attack and fakes an emergency on his naval cruiser to take a closer look.
