Acting personally as Night Rogue, Utsumi helps Sento to collect data for a killswitch to handle the Hazard Trigger. Soon after, Sento is called to a facility containing Fullbottles for Touto, which he finds being attacked by what he recognizes as the "Bikaiser" accompanied by Faust Guardians. [First Chapter]
    • Transforming into Build, Sento defeats the Guardians and Bikaiser, revealing the latter to be a test subject. Recovering the Nebulasteam Gun, Utsumi, having arranged the encounter to collect data himself, achieves a successful transformation into Hell Bro's. [Next Chapter]
  • February 10th: On the eve of battle, Sento decides that he will represent Touto, overruling Ryuga. Entrusting Misora with the killswitch for the Hazard Trigger, he instructs her to use it to stop him from murdering Kazumi even if it kills him. [Victory of Tears]
  • February 11th, 1-on-1 Proxy Battle: On behalf of Touto, Build uses the power of the of the Hazard Trigger to defeat Grease. Though Misora could not bring herself to uses the killswitch, Kazumi's life is saved when Cross-Z Charge intervenes to pacify Build. Unwilling to abide Taizan's terms Tajimi orders an all-out invasion of Touto only to be betrayed by Blood Stalk who reveals that the forces of Seito, backed by Namba and the new Kamen Rider Rogue, have taken the opportunity to seize Hokuto while its forces have been occupied in Touto, with Hokuto's Prime Minister being taken into custody.

  • Having revealed himself as Evolto's benefactor, Shinobu Katsuragi transforms into another Kamen Rider Build, holding his own in battle against the Kamen Riders and leaving Sento conflicted at the thought that his father is the enemy. Seeking to help Sento, Misora approaches Evolto and is infused with Nebula Gas, using the Lost Fullbottle to become the CD Lost Smash. She is, however, saved when Sento uses the power of Genius to transfer the essence of Vernage within her to Ryuga, pacifying his Evolto-influenced violent instincts while freeing Misora of her transformation. Meanwhile, Kazumi and Gentoku head to Faust's lab. [Another Build]
  • As intended, Kazumi and Gentoku increase their power with a near lethal dose of Nebula Gas before being retrieved by their fellow Kamen Riders. Soon after, all four Riders engage Evolto in battle and seemingly destroy him. [The End of Evolto]
  • With Evolto's body destroyed, Shinobu Katsuragi, revealing he was waiting to betray him all along, contains the Evol-Driver holding his essence to prevent his return. However, he is outmaneuvered by Evolto, who had detached a part of himself to possess Utsumi when his body was destroyed, proceeding to kill Shinobu and reclaim his Evol-Driver. After collecting the complete set of Lost Fullbottles, Evolto accesses his complete form which he uses to destroy an alien world only to be stripped of his full power when Build uses the power of the Hazard Trigger to pacify and reclaim a couple of Lost Fullbottles, Sento having realized his father's true intention for the device's use. [The Scientist of Hope]
  • Build Annihilation Plan: Acting in opposition to Evolto in order to hasten the destruction of Earth, the Blood Tribe members compel the populace of Japan, including Ryuga, to hunt down and eliminate Build; their leader, "Kengo Ino", uses the Cobra Lost Fullbottle along with Sento's Hazard Trigger as well as Banjo's Build Driver and Great Cross-Z Dragon to become Kamen Rider Blood. However, with the power of Genius, Sento frees Banjo and, with the power of Vernage combines the Gold Rabbit and Silver Dragon Fullbottles into a Can which allows them both to become the 2-in-1 Kamen Rider Cross-ZBuild, defeating the Blood Tribe much to satisfaction of Evolto, who recovers their Lost Fullbottles for his own use. [Kamen Rider Build: Be The One]
  • [An Oath to Be The One]
  • Having reclaimed all Lost Fullbottles, Evolto returns to his ultimate form by consuming the Moon before turning on the Earth. Gentoku Himuro gives his life to inflict damage upon Evolto's Evol-Trigger, causing him to lose his grip on the Lost Fullbottles and the Black Pandora Panel which, upon fusing with the White Pandora Panel, begins the process of combining the Earth with one from another dimension with no Sky Wall. [Zero Degree Flames] [To The World of Love & Peace]
  • August: After defeating Evolto once and for all, and the two worlds combined, Sento woke up in a new world in a new reality. This new world seemingly different with his friends have no memories of him. However, the Banjo from his world sees Sento and the two are now starting a new life. [The Tomorrow Build Will Create]

New World[]

  • Using the black and white panels of the Pandora Box, Sento Kiryu initiates the process of merging his Earth to World B. He defeats and sacrifices Evolto inside the space-time rift between the two Earths so Evolto's energy is consumed to complete the fusion, resulting in the creation of a New World where the Sky Wall Tragedy never occurred. Every person deceased in one world is retroactively revived by merging with their living counterpart from the other Earth, although some who suffered injuries and fatalities from the Nebula Gas experiments retain the scars on their bodies, including Yui Mabuchi [Build NEW WORLD: Kamen Rider Cross-Z] and former Faust scientist Keiji Uraga, who later discovers that the Sky Wall’s destruction when the New World was fused resulted in natural springs of a condensed form of Nebula Gas called Phantom Liquid. [Build NEW WORLD: Kamen Rider Grease] The only ones who do not fuse with their counterparts are Sento Kiryu, existing independently of Takumi Katsuragi, and Ryuga Banjo, whose counterpart remains separate from him and completely human. Sento chronicles his story into a 49-episode script for a television series. [The Tomorrow Build Will Create]
    • Emerging from the White Pandora Panel, Evolto’s older brother Killbus appears in the New World, stealing Sento’s Build Driver and copying the appearance of flamenco dancer Satoshi Kakizaki before attacking Banjo while he is selling Sento’s inventions as toys. Killbus forces Banjo to catalyze a process that temporarily restores the Pandora Box from the white panel and restores Evolto from within Banjo. Killbus steals Sento’s toy and transforms it into the Killbuspider to become Kamen Rider Killbus. The restoration of the Pandora Box releases an energy wave that restores the memories that former Nebula Gas experiment test subjects had of their past lives. Evolto and Banjo team up to defeat Killbus and stop him from destroying the entire universe. Afterwards, Evolto leaves the Earth peacefully, and Sento treats the injuries that Yui Mabuchi’s hospitalized students sustained from the Faust experiments in the previous world. [Build NEW WORLD: Kamen Rider Cross-Z]
    • The terrorist organization Down Fall—led by Simon Marcus and a vengeful Keiji Uraga—attacks the laboratory where Shinobu Katsuragi has developed a Build Driver and hacks the Guardian forces to stage a takeover of Japan, capturing Gentoku Himuro and his father Prime Minister Taizan Himuro. Their members transform into Phantom Crushers using the Phantom Liquid, while Uraga takes the Build Driver and Hazard Trigger to become Metal Build. The Phantom Crushers use their powers to neutralize the Nebula Gas-based abilities of Team Build and move to steal the White Pandora Panel for Uraga, who betrays Marcus and seizes control of Down Fall. Kazumi Sawatari and the Hokuto Sanbagarasu are able to retain their transformation capabilities due to having retreated to sea and bathed in a hot spring of Phantom Liquid after Misora Isurugi broke Kazumi’s heart. Working with Takumi Katsuragi, Sento Kiryu is able to extract the Phantom Liquid essence from the Hokuto trio’s bodies and derive from it the Grease Perfect Kingdom and tonics that will restore the powers of Nebula Gas subjects. Team Build regains their powers and retaliates against Down Fall, with Grease trading the White Panel for the safety of the captured Misora, giving Uraga the means to transform from Metal Build into Phantom Build. Sento raises Kazumi’s Hazard Level by deceiving him into believing that the Hokuto trio did not survive the extraction of the Phantom Liquid, and his increased power with Grease Perfect Kingdom lets him defeat Phantom Build once and for all. In the aftermath of Down Fall’s downfall, Gentoku and Sawa Takigawa are revealed to have entered a relationship, Nariaki Utsumi perfects the Namba Stick, and Misora asks Kazumi out on a date. [Build NEW WORLD: Kamen Rider Grease]

Behind the scenes[]

Taking place in its own distinct world, Kamen Rider Build premiered on September 3rd, 2017. As a general rule, the dating of the Kamen Rider Series is assumed to correspond at least roughly to its real world broadcast. Indeed, Sento Kiryu's rent notice seen in the first episode is dated September 3rd, a match to the episode's broadcast in 2017. It should also be noted that said rent notice shows that Build's world uses its own year numbering system, using the After Sky Wall as a point of reference. As such, the entirety of the TV series takes place across the years ASW 011 and ASW 012.

The ASW year system is set by ASW 011 = 2017 A.D.[1] However, it is found that the day of week is different from the real world. The week day system is 1 day advance. For example, Kazumi Sawatari's phonescreen as seen in the eighteenth episode shows a date of January 14, 2018, with "Monday" (月, Getsu), which instead Sunday in real world. A weather report also shows the same pattern in the movie. ASW 012 corresponds then to the 2019 calendar, while temporally being the main timeline's 2018.
