Kamen Rider Ghost (仮面ライダーゴースト Kamen Raidā Gōsuto) is a Japanese tokusatsu drama in the Kamen Rider Series, written by Takuro Fukuda.
Daitenkū-ji (大天空寺) is a fictional Buddhist temple in Kamen Rider Ghost which has been taken care of by the Tenkūji family for generations. It is the home and base of operations for the series' main characters.
Takeru Tenkūji (天空寺 タケル Tenkūji Takeru) is an 18-year-old man who is the current heir to Daitenkū-ji. Ten years earlier, his father left him home as he went on a ghost hunting expedition. Before his father apparently died, he sent Takeru a gift of the tsuba from Miyamoto Musashi's katana which he wears on a necklace. As well as his interest in Miyamoto Musashi, Takeru enjoys reading from a book titled Stories of the World's Greatest People (世界偉人伝 Sekai Ijinden) and learning about the history and legends of famous historical figures. Wishing to follow in his father's footsteps as a ghost hunter, Takeru laments being unable to see ghosts, which neither Akari nor Onari believe exist, until he receives an item called a Ghost Eyecon (ゴースト眼魂 Gōsuto Aikon) on his 18th birthday, a gift meant for him should his father have truly died. This allows him to see the monstrous ghosts known as Gamma who then attack and kill him, as they are after the Eyecon themselves. He is brought back to life by a mysterious hermit who grants him the ability to transform into Kamen Rider Ghost to fight the Gamma. The hermit tells Takeru he has 99 days to gather the 15 heroic Eyecons of great men from history in order to fully come back to life through the monolith below Daitenkū-ji, as the hermit's magic is not powerful enough to truly restore him to life. However, after seeing his childhood friend Makoto Fukami become the cold Kamen Rider Specter as a result of his sister Kanon's body being trapped in the Gamma World. When all 15 heroic Eyecons are gathered by Chikara Saionji, Takeru's pure heart and willpower to be a Kamen Rider allows him to be uncorrupted by the monolith's magic and he passes on getting his life back so Kanon can be saved. During his first visit in the Gamma World, Takeru gains the ability to enter a person's memories by touching them. After finishing an investigation of the Gamma's plot on turning most of the middle aged adults into kids with the help of Tutankhanum to restore the victims' actual ages, Takeru hears an unknown female voice, later revealed to be his mother, thanking him when he said something about motherhood. His mother is revealed to have died when Takeru was born, and thus, he is unable to remember her face. As a child before his father's death, Takeru used to disrespect his father for involving him with his so-called expedition. When he later enters Igarashi's memories, he learns that his father kept him along on his expeditions as he saw a hidden infinite potential in him that would make peace with the Gamma World. The hermit also reveals to him that the Eyecon containing his soul was supposed to have contained his father's soul until his death at the hands of a Gamma, and that if he cannot restore his original body within another 99 days both his soul and his father's soul will disappear forever. When entering Adel's memories, Takeru finds out that Adel was the one who killed his father ten years ago, before he killed his own father Adonis years later in the present. However, Takeru notes that Adel's madness was because his and Alain's mother Alicia died in illness, which is why he tells Alain not to blame himself for what happened ten years ago. Once Takeru and his allies discover the true mastermind to be the Gammisers, as they were the ones manipulating Adel and creating Makoto's clones, he manages to defeat them possessing Adel's Perfect Gammiser form with Mugen Damashii, and then the Great Eyeser with both Mugen Damashii and Ore Damashii, thus saving the world. As a debt from the Great Eye for freeing them from the Gammisers and ever since the Great Eye began eyeing Takeru for his heroic deeds since their first meeting, Takeru is granted more than one wish besides reviving himself. Now that he's finally been revived, Takeru can continue his unfinished education in high school. Unfortunately, during Kamen Rider Heisei Generation: Dr. Pac-Man vs. Ex-Aid and Ghost with Heisei Riders, Takeru is afflicted with a Pac-Man based Bugster virus, causing him to die and be unable to transform into Ghost due to the virus in him disabling his rider powers. He seeks CR's help at Seito University Hospital where Kamen Rider Ex-Aid is not only to save himself, but also the other victims infected by the Pac-Man Bugster virus, including his friend Akari, with help from Kamen Riders Drive, Gaim and Wizard.
