This series aired from 2007 to 2008 and ran for 49 episodes. Ryotaro Nogami is a young man with incredibly bad luck who in one day is possessed by a mysterious creature known as an Imagin and discovers the Rider Pass, a device that enables him to transform into Kamen Rider Den-O. When the Rider Pass's owner Hana approaches him, they are attacked by another Imagin, one who come from a possible future to 2007 who grant wishes to weakwilled humans in order to go back further in time to change the past to favor the Imagin's own future. Hana has Ryotaro transform, and the Imagin who possessed him takes pity on him and offers to take over his body and fight in his place. Ryotaro joins Hana, the Imagin Momotaros, and the crew of the DenLiner, which soon includes other Imagin who open contracts with Ryotaro, to protect the flow of time so the future of humanity remains as the one true future.

Ryotaro Nogami is a young man with a lot of bad luck. One day, he finds a strange pass and things got stranger from a mysterious girl and a large time-traveling train to being possessed by an entity called an Imagin, beings from an alternate future whose kind are attempting to change the past. Though slightly confused about the nature of the crisis, Ryotaro, along with the aid of the hot-headed, violent Imagin, dubbed Momotaros, becomes Kamen Rider Den-O, traveling to different times on the DenLiner to battle the evil Imagin to prevent them from altering the past to affect the present and future. During his adventure, Ryotaro is joined by other Imagin who aid him as well; the lying, manipulating and womanizing Urataros, the herculean (and narcoleptic) Kintaros, and the childish yet powerful Ryutaros. He later meets the mysterious Yuto Sakurai and his bumbling Imagin partner Deneb. Yuto is not only Kamen Rider Zeronos but is the younger incarnation of Ryotaro's older sister Airi's fiance, Sakurai, who mysteriously disappeared and is tied to the mysteries involving the Imagin and a person known as the Junction Point.

Imagin (イマジン Imajin^?) are creatures from the future who have come to the year 2007 in hopes of changing the past to alter their future to their liking. To reach this goal, Imagin grant the wishes of weak-hearted humans and then go back in time to that individual's most precious memory. When they lose control of their humanoid forms, Imagin grow into massive proportions known as Gigandeath.
