 * Over 30,000 years ago  OverLord the twin entities, embodiments of Light & Darkness battled to settle who will rule over their creation, Before dying by his brother's hand, The OverLord of Light bestows his essence to humans so that someday they will be able to awaken his power within them. The OverLord of Darkness then created his emissaries as protectors of humanity but they must eliminate humans who posses the Seed of Agito. Before he passed away, the OverLord left his very own DNA model in the mysterious puzzle artifact. Over 30.000 years later, some scientists solved the puzzle and using his DNA model to recreate him.
 * 10,000 years ago: The Undead are created by God in the form of a stone slab called the Stone of Sealing, to kill each other in a free-for-all battle royale known as the Battle Fight, with the winner granted a wish to alter the world. The 52 Undead represented 52 different species and battled so they can wish for the species they represent to rule the Earth, while the Joker represented death. While the other Undead were sealed by the Monolith, the winner of that battle was the Human Undead and the world has been populated by humans ever since.
 * Early human civilization: The Gurongi, a mysterious ancient civilization consisting of beings that can transform into monsters to kill people for their ruthless game, which is translated into the Gurongi Language as the "Gegeru", attack their rival civilization the Linto, the original Kuuga defeats the leader of the Gurongi and seals all 200 of the Gurongi away. The Linto's success in defeating the Gurongi was because of the Lords, who had revealed to them how to make Kuuga's equipment.
 * 1211 A.D.: The Greeed are created from the fifty Core Medals by humans who attempt to create life under the will of the King, the First Kamen Rider OOO, as part of his plan to achieve godhood. Though originally mindless, the five Greeed gained wills of their own after one Medal in each of the five sets was destroyed. They are beings without true life that crave endlessly, cursed with a void in them that can never be filled. They lack proper senses, resulting in bleak sensory input (e.g., colors are washed out, taste is nonexistent, sounds are muffled and distorted), as well as the inability to feel deeper emotions such as love. As such, the four other Greeed became bent on filling the void left in them by consuming everything obsessively in an attempt to experience what humans normally take for granted. However, they and part of Ankh were sealed by the King when the Core Medals consumed him and transformed him into a stone coffin.

Wizard

 * The Sabbath: On the day of a solar eclipse, Wiseman performs a ritual involving the gathering of many Gates, humans with magical potential, who were forced into deep despair and sacrificed, giving birth to the Phantoms. These Phantoms seek to increase their numbers through placing more Gates in despair to create more of their own kind so the Wiseman can perform the Sabbath once more. One of the Gates who was sacrificed was Haruto Souma, but he survived thanks to the promise he made as a child to his parents, when they were on their deathbed after a car accident, to keep hope alive in his heart. He was able to keep his inner Phantom, Dragon, from tearing him apart from the inside through sheer willpower, Haruto was one of the very few to have survived the ritual and emerged with the ability to perform magic.
 * In the aftermath of the ritual, Haruto is attacked by a Phantom but is saved by the White Wizard, who entrusts another Gate, Koyomi, who also survived the ritual but lost her identity, to the youth while giving him the Wizardriver and the Flame Ring to fight the Phantoms as Kamen Rider Wizard. Haruto and Koyomi go to the Antique Shop Omokagedo, seeking Shigeru Wajima, who made the Wizard Rings. Wajima would go on to make more and more rings for Wizard to use in his fight against the Phantoms.
 * The Phantom Gargoyle is assigned to go after a high school student named Naoki Katayama, murdering his detective father when he attempts to stop him. But due to Kizaki honoring his late partner's request, Gargoyle never gets to Naoki as he is sent to Akita Prefecture.
 * Six months after the Sabbath, Haruto encounters rookie detective Rinko Daimon, whom he discovers is a Gate just as she is forced into despair by the Phantom Minotauros. Haruto destroys Minotauros then travels to Rinko's Underworld, using his own Phantom, now known as WizarDragon, to destroy Rinko's source of magical potential and inner Phantom Jabberwock, giving her the hope she needs as well as rendering her a normal human.
 * Haruto meeets a young man, Shunpei Nara, who wishes to be a wizard. When Shunpei is attacked by the Phantom Hellhound and his Ghouls, Rinko returns, coming to his and Haruto's aid. She tells Haruto that she will help people, magic or no magic.
 * Hellhound, assuming the form of his Gate, takes advantage of Shunpei's wish to be a wizard, creating the illusion that he can cast fire spells, then forcing him into despair after revealing the deception and his true self. Haruto destroys Hellhound and travels to Shunpei's Underworld, destroying his inner Phantom Cyclops and rendering him a normal human. Shunpei makes himself Haruto's assistant, saying that he will help Haruto even if he doesn't have magic.
 * Koyomi's nature is revealed to Rinko and Shunpei. The lazy Phantom Caitsith is forced to target pianist Eisaku Takagi who has fallen into a performance slump.

As Wizard destroys Caitsith, Takagi loses the piano competition again but decides to move on by moving overseas and starting over with his career, thanking Koyomi for inspiring him.

With WizarDragon's power, Haruto assumes Flame Dragon Style. He manages to save Hiroki's parents and destroyed Phoenix, though unknown to Haruto, he revives himself later on.
 * Naoki Katayama returns to Tokyo to learn the truth behind his father's death. Kizaki has Wajima kidnapped so he can make him a Wizard Ring using a green Magic Stone he has obtained.

This causes a guilt-ridden Naoki to fall into despair and his inner Phantom Jörmungandr to manifest. With time running short. Kamen Rider Wizard Flame Dragon quickly destroys Gargoyle before entering Naoki's Underworld to exterminate Jörmungandr.
