New Kamen Rider SEGA
Status
Summary
AR SEGA no Sekai. After a new form of Shocker arises, Kamen Rider Ichigou follows them to a world with no Riders. An accident occurs of sorts where a piece of gem is left near a normal Dreamcast, and then, that world's first Kamen Rider is born, Heisei Kamen Rider #17: SEGA!
