Ryotaro Nogami is seemingly the unluckiest man in the world. During the day, he works at his sister’s café, but the rest of his life he’s lucky if he doesn’t end up hurt during mundane activities like riding his bike and ending up at the top of a tree or being accosted by a gang of thugs after being saved by a rescue team. One day, he picks up a strange train pass on the ground, and when he happens to enter a building at exactly 11:11:11 am, he finds himself in a vast, barren desert with a massive train as the only thing within. After returning to reality, he meets a young woman named Hana who says she is the owner of the Rider Pass that Ryotaro found. As she tries to retrieve it, both are met by a gang of thugs that attacked Ryotaro earlier, and Ryotaro is revealed to be possessed by an Imagin, a monster who has travelled back in time to change the flow of history to favor their future over humanity’s. The hot-headed Imagin calls itself Momotaros, but Momotaros can’t seem to do more than possess Ryotaro, which leads Hana to realize he is a Singularity Point who is immune to changes in time. One of the thugs, however, has an Imagin as well, and this Imagin is looking to use him to travel farther back in time to change the present and future. Hana gives Ryotaro the Den-O Belt, allowing him to transform into Kamen Rider Den-O to fight the Imagin, but his own meek personality makes him a poor warrior.

Yuto Sakurai, a man who Ryotaro realizes shares his name with his sister’s missing fiance, and his partner Imagin Deneb later join Ryotaro in protecting the timeline as Kamen Rider Zeronos, although their methods in protecting the flow of time differ in that Ryotaro believes they should save people while Yuto does not see that as necessary in the scheme of things.

The O Medals, divided into Core Medals and Cell Medals, are the essence of creatures known as the Greeed, homunculi driven by their own incomplete experience of the world such that they create monsters called Yummy to harvest more Cell Medals from humans in a futile attempt to become whole. One of the Greeed named Ankh realizes he is missing most of his body and exists solely as a disembodied arm, so he steals some of his fellow Greeeds’ Core Medals to put them at a disadvantage, but he discovers Eiji has inadvertently taken one of his own Core Medals believing it to be his own pay after the museum is destroyed in the resurrection of the Greeeds.

Haruto Soma is one of a few survivors of a magic ritual called a Sabbath that sought to use him to unleash monsters called Phantoms upon the world. These Phantoms now seek out Gates who are mundane humans who have the potential to become fellow Phantoms if they are brought to the brink of despair, opening up their internalized reality called an Underworld where a new Phantom may be born to take over.

Kouta Sakuraba is one of the many young residents of the city of Zawame who have become dejected due to the imposing influence of the Yggdrasill Corporation whose tower dominates the skyline. To escape this feeling of being peasants in a castle city, the youth of Zawame have formed break dancing crews to add some fun to their lives.

As time goes on, more Inves appear in Zawame, meaning Helheim Forest is slowly encroaching on our reality to subsume it entirely.

Sougo, Tsukuyomi, and Geiz who also can become Kamen Rider Geiz himself work together travelling through time to prevent the Time Jackers from changing history to install their own tyrannical king while keeping an eye on Sougo, whose ability to obtain other Kamen Riders’ powers through other Ridewatches is eerily similar to the evil Oma Zi-O they fear he may become. Things only become more complicated when another Woz appears from the future claiming to come from a future where Geiz has become the savior of time and space and he can transform into Kamen Rider Woz, much to the original Woz’s chagrin.

Touma is attacked by a monster called a Megid which is a type of creature native to Wonder World that has been given more powers by an Alter Ride Book that has the power to change the world. Touma is enraged that the Megid would attack people for no reason until he realizes that a book he found earlier is actually a Wonder Ride Book. It provides him with the Seiken Swordriver that allows him to transform into Kamen Rider Saber to defeat the Megid, which returns everyone to Earth. However, this now puts him in the sights of the Sword of Logos organization, an ancient sect of knights who are tasked to protect the Book of the Ancients, and they want to know how Touma has come across one of their missing Seiken Swordrivers and Wonder Ride Books.
The sommelier Goro is brainwashed and transformed into a cyborg by the evil former anti-terrorist unit Shade, until he sees his girlfriend amongst hostages Shade has taken at TV Asahi’s Tokyo headquarters. He regains his memories and fights off his former allies until the ranking members are revealed to be Worms. Goro then uses his Rider Belt to transform into Kamen Rider G to fight the Worms, until he is overpowered by their leader the Phylloxera Worm. However, Kamen Rider Decade and the other Heisei Kamen Riders give him the encouragement he needs to defeat the Phylloxera Worm and save the day, vowing to spend the rest of his life fighting Shade.
The meek Haruka Mizusawa discovers that he has become infected by Amazon Cells, a creation of the Nozama Pharmaceutical Company, which makes him transform into Kamen Rider Amazon Omega, awakening in him a cannibalistic hunger and the urge to kill others who have also been infected by Amazon Cells to transform them into creatures called Amazonz. He finds himself pitted against Nozama Pharmacy’s Nozama Peston Service, a cell of paramilitary fighters hired by Nozama to hunt down rogue Amazonz, and Jin Takayama, a former researcher at Nozama who infected himself with Amazon Cells to turn himself into Kamen Rider Amazon Alpha. Five years later, a boy named Chihiro, who has been raised from birth by Amazonz, must suppress his urges to kill those around him as Kamen Rider Amazon Neo, until he meets an Amazonz who he does not want to kill.
