Determined to protect everyone and save the city, the flaming sword along with the slumbering fire dragon was awakened by Miyuki once again and allowed her to become Kamen Rider Saber. A new story has begun. A buried past has been dug up. Two old friends return to the dead. New connections. Another mysterious enemy.
