To rid Destron of its witness, and taking no chances, they sent Scissors Jaguar to murder the entire Kazami family. Though he was forced to watch his family die before his eyes, Shiro was saved from the same grisly fate by the interference of Kamen Riders 1 and 2. Bent on revenge for his family's deaths, Shiro pleas the Kamen Riders to make him into a cyborg just like them. The two Kamen Riders refuse at first, but after Shiro was fatally wounded while saving them, the two had no choice but to respect his wishes.
