At 17, he was the youngest member of the Gorangers. Kenji was training at the Kansai branch of the Japan Block of EAGLE. As someone without a care in the world, he sometimes was a bit brash and temperamental. As Mido Ranger, he was armed with the razor-sharp Midomerang (Green-boomerang) which can be flung at enemies. He could also use it as a handheld weapon to cut and slash his opponents. His Midomerang was later upgraded to the New Midomerang which was a bit bigger. He also carried the Mido Puncher which was a slingshot weapon which could be used to fire pachinko-ball pellets and sometimes explosives. Asuka drove the super motorcycle Green Machine and later the Green Star. [The actor Yukio Itou (also known as Takeshi Itou and Takeshi Shoudou) also played the original Battle Cossack in Battle Fever J.]
