During Gatanothor's descent, Sawai ordered the evacuation of all personnel in the Dive Hangar to the Artdessei after Gatanothor's darkness had reached the base. He ordered Tetsuji Yoshioka to evacuate after the latter had declared his intent to sink alongside the base, calling him a fool to throw his life away. Sawai then watched Tiga's battle with Gatanothor and eventually came to learn that Daigo was Tiga after the Ultra's defeat and Rena's proclamation. Later on, he recruited Keigo Masaki to participate in the campaign to revive Tiga by using the light-gene converter to deliver the light to the Ultra. After Gatanothor's death, Sawai congratulated Keigo for his efforts and celebrated humanities' victory with his allies. Master of DarknessTo the Shining Ones
