Godzilla vs. Biollante
After moving from Saradia due to the killing of his daughter, Genshiro Shiragami lives in a house near Lake Ashi, and it is here where he continues to tend to the rosebushes containing her soul. After Mount Mihara erupts, some of the rosebushes are damaged, and in desperation, Shiragami injects the DNA of Godzilla into the plants. Agents from both Bio-Major and Saradia storm the house, but are killed by an unknown force. The next morning, Shiragami and Miki Saegusa find the building in ruins, and go outside to find that Biollante in her rose form had grown from the plants, then smashed through the house and rooted herself in the shallows of the lake. Shiragami names the giant plant Biollante, and looks on in astounded reverence, as the plant monster begins to call out to Godzilla, who had just made landfall in Odawara. Godzilla and Biollante later battle in the Lake, and Godzilla is seemingly victorious, forcing Biollante to dissipate into spores and rise away from the lake. Later, Biollante returns, and battles Godzilla on the shores of the lake in her final form, but is wounded once again and has to dissipate into space. Shiragami witnesses the entire fight, and feels at peace when he knows that his daughter lives on in Biollante's rising cells, but can't live to see the monster again, as he is quickly killed by the Saradian spy, SSS9.
