The former Imperial Navy officer Kawai, who brought the heart to Hiroshima's army hospital, is now working in an oil factory in Akita Prefecture, when a sudden earthquake destroys the refinery. Kawai catches a glimpse of a non-human monster within a fissure before it disappears. Meanwhile, Bowen and his team find out that the strange boy is growing in size due to an intake of protein. Afraid of his strength, the scientists lock and chain the boy in a cage and Sueko, who cares for him, feeds him some protein-filled food to sustain him. Bowen is visited by Kawai, who tells him that the boy could have grown from the heart of the Frankenstein Monster, as the boy was seen in Hiroshima more than once before. At Bowen's advice, Kawaji confers with Riesendorf in Frankfurt. Riesendorf recommends cutting off a limb, speculating that a new one will grow back. Sueko and Bowen strongly object to this method.
