Takeru Tenkūji, whose father is a ghost hunter who died 10 years earlier, dies at the hands of an evil monster known as a Ganma (眼魔, lit. "Eye Demon") when trying to protect his childhood friend Akari Tsukimura from an attack. A mysterious hermit brings Takeru back to life and bestows upon him the Ghost Driver transformation belt and the Eyecons (眼魂（アイコン） Aikon, lit. "Eye Souls"), a device which can see ghostly creatures like spirits of dead creatures, Ganma, and the other Riders like Ghost. The hermit tells Takeru that he has 99 days to gather the remaining 15 Eyecons in order to be brought back to life permanently, and he must fight the Ganma as Kamen Rider Ghost to obtain them. He is assisted by the Buddhist priest Onari, who previously supported his father as a ghost hunter, and Akari as she is trying to find more scientific reasons behind their supernatural encounters. In his way are Makoto Fukami, a mysterious living young man capable of utilizing a Ghost Driver to transform into Kamen Rider Specter (仮面ライダースペクター Kamen Raidā Supekutā), and the Ganma led by Aran and his mysterious benefactor. The Kamen Riders of Kamen Rider Ghost use Eyecons to transform and to summon the hooded jacket-like spirits called Parka Ghost (パーカーゴースト Pākā Gōsuto) like the spirits of historical figures such as Miyamoto Musashi, Thomas Edison, and Isaac Newton to grant them new powers.[1]
