Tenkuji Takashi, who wanted to become a ghost hunter, received a Ghost Eyecon from his late father on his 18th birthday. A strange man from another world, the Eye Demon, suddenly appeared in front of him and set his eyes on it. He even died to save his childhood sweethearts Tsukimura Akari and Onari. With the help of the immortal, he obtained the Ghost Driver and transformed into Kamen Rider Ghost, and was able to revive his short life for 99 days. In order to collect the Eyecon of "15 great men" who wished to be resurrected, he threw himself into a battle that would affect the fate of the world.
