Riders 1 and 2 ride off with their painful struggle seemingly at an end, but they are attacked by a car mounted with machine guns and adorned with the Tachibana Racing ClubIcon-crosswiki logo. It turns out that the vehicle is manned by another Kamen Rider who identifies himself as Kamen Rider 3Icon-crosswiki who was designed to destroy Riders 1 and 2. They do battle, but Rider 3 is able to take on both of them easily by himself. Riders 1 and 2 use their Rider Double Kick, but Rider 3’s own Rider KickIcon-crosswiki destroys Riders 1 and 2, and a green shockwave covers the land.
