|~ Tsuyoshi Kaijo.|
Tsuyoshi Kaijo (海城 剛 Kaijō Tsuyoshi) is Akarenger (アカレンジャー Akarenjā), leader of the Gorengers, with the designation number "1". He is the younger brother of the Kantou EAGLE base captain.
When the Black Cross Army launched an assault on the EAGLE bases in Japan, a force led by Gold Mask attacked the Touhoku base, slaughtering everyone with only Kaijou surviving after watching his brother die. Along with the survivors of the other bases, Kaijou was summoned to Snack Gon, the secret gateway to EAGLE Japan's main command center by Japan's EAGLE Commander Edogawa Gonpachi. 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.
