When the Black Cross Army launched an assault on the EAGLE bases in Japan, a force led by Bronze Mask attacked the Kyushu base, slaughtering everyone with only Daita surviving. Along with the survivors of the other bases, Daita was summoned to Snack Gon, the secret gateway to EAGLE Japan's main command center by Japan's EAGLE Commander Gonpachi Edogawa. There they were given special formfitting electronic battlesuits, which empower its wearer with various superhuman abilities. Edogawa told them that they are the Secret Squadron "Gorenger", the world's best chance against the forces of the Black Cross Army. Their first battle was with Gold Mask, who they destroyed with the Gorenger Storm.
As Kirenger, he was armed with the “Ki Sticker” which was a fighting pole whose head can be outfitted with various attachments such as a punching fist. He also utilized the “YTC” radio which could jam electronic circuitry. He rode in the “Blue Machine / Blue Star” sidecar. He also co-piloted the “Varibloom” and “Varidreen” sky vehicles.
