Sento Kiryu (桐生戦兎, Kiryū Sento), born Taro Satou (佐藤太郎, Satō Tarō), is a genius theoretical physicist who experiments with Fullbottles to further enhance his abilities as Kamen Rider Build (仮面ライダービルド, Kamen Raidā Birudo) to fight against the evil Smash organisms.

History

Early Life

Born Taro Satou, he was friends with Tatsuya Kishida during middle school and formed a band called Lynks with him in their adulthood. However on September 5, as Taro left for a job offer at Takumi Katsuragi's apartment, he was presumably kidnapped by Faust, after which Blood Stalk was deemed responsible for his memory loss, with a single memory left behind which detailed the experiments done on him by Night Rogue. Taro later escaped with no memory of his past and was found lying down in a strange alleyway by Soichi Isurugi, the owner of the café Nascita. With no identification, he was given the name Sento Kiryu and taken into Isurugi's care, hidden in the secret basement laboratory inside Nascita.

Becoming Build

Sento is given the Build Driver — Soichi gives Sento the Build Driver.

File:Buildfirsttransformation13.jpg

At some point after being taken in by Soichi, he was provided a Build Driver and a set of Fullbottles that Soichi stole from Faust. During Sento's first fight against a Smash, he had fought by-hand but was beaten to the point where he had no choice but to use the driver. Upon his first transformation, Sento defeated the Smash and headed back to Nascita, where Soichi and Misora were waiting for him. From that day on, Sento would continue being Build in order to one day uncover the mysteries surrounding his past.

The Rabbit Tank Meets Dragon

After about a year of fighting as Build, Sento had gained some notoriety as the Kamen Rider. However, Sento's search was left at a standstill, as the Smash had no memories of their own experiments upon returning to human form. Meanwhile, Soichi, growing impatient with Sento's freeloading, directed him to a mid-level job at Touto Institute of Advanced Matter Physics.

Sento's first lead came in the form of Ryuga Banjyou, an ex-fighter and wanted fugitive. Alerted by Ryuga's Smash energy readings, Sento followed and eventually apprehended him. Much to his shock, Ryuga had just escaped from the labs where Sento had been experimented on, and had all his memories intact. The two were interrupted by Strong Smash, who attempted taking Ryuga away before Sento defeated it as Build. The Touto government quickly arrived and attempted to take Ryuga back into custody. Believing Ryuga's claim that he had been framed, Build helped Ryuga escape from the government, making Build a fugitive as well.^{[That One with the Best Match]}

Burn Smash Incident and Meeting Night Rogue

Sento hides Ryuga in the secret lab, with Soichi scolding Sento for committing a felony. Sento explained that Ryuga was the 'best match' to his memories as they are both experimented by the same scientist group. On top of that, with exception of the location of the underground lab, Ryuga still had his memories intact. Sento deduced that Ryuga might lead him to the bat man and starts questioning him, but was put to a pause due to a Smash alert (a false trail to lure Build out).

Sento returned to discover Ryuga escaped, later discovering Ryuga's fiancé, Kasumi to have also been abducted by the scientists as well. Ryuga choked him into unconsciousness from getting him involved, but managed to catch up and was too late seeing that Kasumi was already transformed into Burn Smash. Then Night Rogue appeared, where Sento fought to demand answers for his experimentation, but responded that he cared less about every human subject his affiliation experimented. Night Rogue disappeared after delivering the bad news: Kasumi's body was too weak to be restored, and removing her Smash essence would be fatal. Realizing that Kasumi cannot be saved despite Ryuga's pleas, Sento calculated the only way to end her suffering by separating her consciousness long enough for her and Ryuga to say their goodbyes. Ryuga broke down with grief with nothing left to fight for until Sento reminded him Kasumi's life will be for nothing if he gave up and surrender. Sento returned to the lab where Ryuga followed thanked him for the latter, and deciding to cooperate in discovering the truth behind the scientists.

Other Appearances

Seeking a sample of Ex-Aid's essence, Build mistakenly intercepted Kamen Rider Genm while he was fighting through the Bugster Virus hordes of Gamedeus Cronus. Switching to the GorillaMond Form to engage him, only after eliminating one of Genm's lives did Build realize that he was not Ex-Aid and promptly took his leave after identifying himself to Dan. ^{[The Last Smile]} Inspired by this encounter, Dan created a Rider Gashat based on Build, the latest in his collection of those of the Heisei Riders, ^{[Kamen Rider Ex-Aid "Tricks": Kamen Rider Genm]} which Emu Hojo snatched from his hand and activate it. ^{[Endless Game]}

Personality

As Taro Sato

Not much to be known of his past life, although according to Tatsuya, he is hinted as a rebellious man who has a large dream of living a luxurious life should their band Lynks become successful. His former apartment implied Taro as a man who lacked a sense of hygiene. Despite all these negative traits, he is nevertheless kind to his friends due to his job application in Katsuragi's lab stems from the need to provide Tatsuya with financial support.

As Sento Kiryu

2

"You know, in spite of how it may seem, I'm actually a pacifist."

―Build to Genm^[src]

"For the justice I believe in, I will beat you!"

―Sento to Blood Stalk^[src]

Sento is a highly intelligent and sarcastic young man: He likes to praise himself for his works, and has a somewhat child-like curiosity when learning new things, such as when he first sees the Pandora Box. Additionally, when he gets excited, a part of his hair sticks up. On the other hand, Sento is generally composed and calm while fighting.

But when Sento is not composed, he immediately rushes to settle things as seen when he finally met Night Rogue, even telling that he didn't care to know his name when Night Rogue introduced himself, and attacking Night Rogue carelessly. However, rage also enabled Sento to bring his ability as Build to higher potential, shown when he single-handedly managed to injure Blood Stalk. Blood Stalk comments that both Sento and Banjou were exposed to the same Nebula Gas amount to turn people as Smash, thereby classified them as Hazard.

Despite his eccentricity, Sento is a honorable hero. During his job as a Kamen Rider, he always upholds heroism without expecting anything in return.

Sento has a couple of catchphrases. Before he transforms, he says "Now, shall we begin the experiment?" (さあ、実験を始めようか？, Sā, jikken o hajimeyou ka?). After transforming, he says "The laws of victory have been decided." (勝利の法則は決まった, Shōri no hōsoku wa kimatta).

Powers and Abilities

Hazard Level 3 Physiology: Sento has undergone an experiment from Faust which injected him with a certain amount of Nebula Gas. However, instead of mutating into a Smash, the gas retained his body without side affects aside from memory loss. As result, his initial Hazard Level starts at Level 3, where subjects like him can utilize the Build Driver to transform into Kamen Rider Build.
Genius-Level Intellect: Sento's most defining trait is his intelligence. He has an advanced knowledge of physics, and developed several of Build's accessories on his own.
- Genius Physicist: Sento has an advanced knowledge of physics, having finished a difficult physics test with perfect results. This proves a significant asset in battle, which Sento incorporates into his fighting technique.
- Genius Engineer: Sento has built the majority of Build's accessories, as well as all of Cross-Z's equipment, on his own.
- Strategist: Sento has shown him to be a capable strategist, being able to outwit even Blood Stalk on two occasions.
Fullbottle Augmentation: By using a Fullbottle in his hand without transforming, Sento can gain abilities based on said Fullbottle's traits:
- Rabbit: Allows Sento to gain fast reflexes. First used to defeat Ryuga Banjou in a one-on-one fight.
- Gorilla: Allows Sento to perform fiery punches. First used to fight Ryuga Banjou.

Weaknesses

Narcissism: Sento has overwhelming confidence in his own skills, so he tends to be proud of his own achievements and look down on others (especially anyone who relies on his inventions), which contributes to his prideful personality. Sento often relies on his own skills to solve problems and never expects sudden assistance from others, so when it happens, he tends to either be surprised or turns them down. Also Sento can be easily caught off guard when he accomplishes anything or witnesses something unexpected and new which excites him, due to his reliance on his intellect. In this state, he is vulnerable to any surprise attacks.
Desperate Curiosity: Sento can be easily attracted to anything that is mysterious and interesting and tends to do a total discovery for it, such as new innovations and anything that brings him closer to uncovering his past. This will continue until either he reaches a conclusion or someone forcibly stops him during progress.
Dragon Fullbottle: As seen in episode 10, Sento does not have a full control of the Dragon Fullbottle as he transforms into Build KeyDragon, which causes him to be electrified by the energy surges and experiences intense pain. Further use of the Dragon Bottle causes his body to be engulfed in flame-like energy which hurts him even more and forcibly knocks Sento out of transformation. This was due to Ryuga's Hazard Level 3 better synchronizing with the Dragon Full Bottle from prolonged use and exposure to its energy, while Sento had never used it before and lacked that immunity.

Forms

Sento sets two different Fullbottles into the Build Driver and turns the crank to transform into Kamen Rider Build. Kamen Rider Build, like Kamen Riders Double and OOO before him, can assume a variety of different forms, called Trial Forms (トライアルフォーム, Toraiaru Fōmu), using different combinations of Fullbottles. However, each one has a Best Match (ベストマッチ, Besuto Matchi) with another Fullbottle that creates an especially powerful form. Best Matches usually have unique names in comparison to other mismatched forms, and the caps of Fullbottles indicate what Fullbottle is its Best Match.

Build initiates a finishing attack by turning the Build Driver's Vortex Crank again. The finisher of all Trial Forms is called the Vortex Attack (ボルテックアタック, Borutekku Atakku), while the finisher of all Best Matches is called the Vortex Finish (ボルテックフィニッシュ, Borutekku Finisshu).

In any form that uses the Rabbit Fullbottle, Build is armed with the Rabbit Foot Shoes (ラビットフットシューズ, Rabitto Futto Shūzu) on his left leg for increased jumping, and can summon the Drill Crusher.

RabbitTank Form

"Rabbit! Tank! Best Match! Are you Ready? Hagane no Moonsault! RabbitTank! Yeahhh!"

―RabbitTank's transformation announcement^[src]

Rider Statistics

Rider Height: 196.0 cm
Rider Weight: 99.0 kg

Ability Perimeters:

Punching Power: 9.9 tons (right arm)/17.0 tons (left arm)
Kicking Power: 23.7 tons (right leg)/17.8 tons (left leg)
Maximum Jump Height: 55.0 m
Maximum Running Speed: 100 m. per 2.9 sec.

RabbitTank Form (ラビットタンクフォーム, Rabitto Tanku Fōmu) is Build's red and blue primary and default Best Match form form accessed from the Rabbit and Tank Fullbottles, hence known as the Moonsault of Steel (鋼のムーンサルト, Hagane no Mūnsaruto). It is themed after a rabbit and a tank.

RabbitTank is considered to be the most well balanced; having a good amount of power and agility in all of his Ability Perimeters, thus making it Build's default form, despite it being capable of initiating transformation with any set of Build's Fullbottles. This is also Build's second fastest form.

In this Best Match form, Build is armed with the Tank Roller Shoes (タンクローラーシューズ, Tanku Rōrā Shūzu) on his right leg for kicking attacks, and can also act as a working tread to roll along on a flat foot.

This form's weapon is the Drill Crusher.

As a Best Match, this form has two finishers:

Build Driver finisher:
- Vortex Finish (ボルテックフィニッシュ, Borutekku Finisshu): Build dives underground to send a white energy chart flying up to the surface with the dotted line securing the enemy before leaping back up, and delivering a kick whilst riding the chart's line. According to Blood Stalk, this finisher has a Hazard Level of 3.2, and then 3.7 when Build attacks him out of anger.
Drill Crusher finisher:
- Vortex Break (ボルテックブレイク, Borutekku Bureiku):
  - Blade: Build channels the energy of a Fullbottle in his Drill Crusher and performs a powerful slash.
    - Rabbit: The Drill Spiral Blade spins such that it creates an energy whirlpool before Build performs a red energy slash.
    - Ninjya: Purple energy Drill Spiral Blades are projected and spin violently around the Drill Crusher.
  - Gun: Build channels the energy of a Fullbottle in his Drill Crusher and performs a powerful blast.
    - Harinezumi: Build shoots white energy spikes at the enemy.

Build uses the BLD Prism Glove creates a gust full of diamonds and uses the Muscle Glove to punch them at the enemy. The diamond then creates a tornado that causes a human to separate from his/her Smash form, then Build punches the Smash inside the tornadoes, thereby defeating the Smash.
Build stops an enemy's projectile attack in mid-air with the BLD Prism Glove, altering the projectiles' atomic structure into a diamond shield. He then punches the shield with the Muscle Glove, shattering it and sending the shards flying at the enemy at high speeds.

Relationships

nascita coffee
- Soichi Isurugi / Blood Stalk: Sento was taken in by Soichi during their first encounter, as Soichi believed that Sento had the potential to become Build. Stalk views Build as equal to Night Rogue, but takes his words and assistance into account. He believes that science will one day bring the end of mankind, but Sento disagreed. Before being aware that Soichi was Stalk, Sento's relationship with the shop owner was on very good terms. However upon realizing the two were one and the same, Sento vowed to defeat him and uphold his sense of justice he always had believed in.
- Misora Isurugi: Sento always uses her for fertilizing Fullbottles, likely being introduced to her ability by Soichi when he suggested Sento become Kamen Rider Build. Although they usually bicker and prank each other, Sento cares about her greatly.
- Ryuga Banjou: Ryuga is titled as Sento's "best match" by Sento for helping him search for his memory and Night Rogue, as he's the only surviving experiment who retained his memory and escaped before entirely becoming a Smash. They are shown to constantly banter, however they do trust each other. When Soichi revealed his true plans, Ryuga got angry and attacked Blood Stalk for Sento and Misora's sake.
- Sawa Takigawa: Sawa was saved by Build before he unknowingly revealed his identity and led her to his base. In exchange for her silence, she asks that Sento gives her an interview on the Kamen Rider. Sento agreed on the condition she not only kept his identity secret, but also aid him in solving the mystery of the Smash and his missing memories. Eventually, Sento finds Sawa a bit annoying, as she comments wildly when he is trying to battle. After turned into Smash by Night Rogue and saved by Ryuga as Cross-Z, Sento and Ryuga are shocked as Sawa tells them that she's actually a Faust Spy. In the end, after Sawa explained her reason to become spy, Sento forgives her. Sawa is shown to have upheld her dignity and sought Soichi's past files on Sento's request.

Enemies:
- Gentoku Himuro / Night Rogue: Sento trusts Gentoku as a more senior employee. Sento views Night Rogue as a rival, with this hatred is fueled further by how he was responsible for the former's experimentation and loss of his past memories. However when Soichi revealed Gentoku's true identity as Night Rogue, Sento confronts Gentoku and they fight.

Past Riders:
- Emu Hojo: It's unknown why Sento planned to attack Emu and take his essence.

Others:
- Tatsuya Kishida: Before Sento's disappearance, he was childhood friends with Tatsuya and were bandmates. They were so close that they called each other "bros." After Sento became Build and reunited with Tatsuya, he had no memory of him but continued to protect him as his duties of Build.

Behind the Scenes

Portrayal

Sento Kiryu is portrayed by Atsuhiro Inukai (犬飼貴丈, Inukai Atsuhiro).^[13] As Kamen Rider Build, his suit actor is Seiji Takaiwa (高岩成ニ, Takaiwa Seiji) and Yuya Nawata (縄田雄哉, Nawata Yuya) in his televised debut in the 44th episode of Kamen Rider Ex-Aid.

Rider No.

As the leading rider protagonist of Kamen Rider Build, Build is labelled Kamen Rider #34 (仮面ライダー34号, Kamen Raidā Sanjūyongō) and Heisei Rider #19 (平成ライダー19号, Heisei Raidā Jūkyūgō).

Etymology

The kanji used to spell his first name, Sento (戦兎, Sento), is composed of the first kanji for tank (戦車, Sensha) and the kanji for rabbit (兎, To); this is referring to Build's primary form, RabbitTank. In-universe, he was given this name by Soichi Isurugi for this reason, who also took Sento's last name, Kiryu, from the name of the barber he had been heading to at the time he found Sento.

His real name, Taro Satou (佐藤太郎, Satō Tarō), is likely referring to the names of two subjects related to "rabbit" and "tank" in real life. Taro is derived from the EH500 Kintaro Tank Freight Train and Satou is derived from a Japanese picture book, Sato the Rabbit (うさぎのさとうくん, Usagi no Satō-kun).

Notes

Sento as a Rider makes a variety of callbacks to previous Riders in an attempt by Toei to bring the franchise back to its roots:
- Build's design uses more basic Kamen Rider design cues than many of his recent predecessors, such as large compound eyes, antenna-like features, and his unique motifs being less prominent in his main form.
- Build's functionality and design is extremely similar to Kamen Rider Double, the Rider who kicked off the second phase of the Heisei Era, using two trinkets in his black and red Driver to interchange halves of his Forms. Other similarities include form names that combine the names of the trinkets in use, and being the first Rider since Double to not have a unique term for his Forms.
- Build RabbitTank's color scheme is reversibly similar to Para-DX Perfect Knockout Gamer Level 99, which uses blue and red color connection.
- Sento's imprisonment and experimentation on by Faust is a reference to the Shocker experimentation origins of the Showa Era Riders.
- Sento's Ninjya Fullbottle creates a half form that gives him a scarf, making him the first main protagonist Rider since Double to have that classic design element.
- His Driver is also similar to that of Kamen Rider OOO, as there is a set number of collectible items required for a form, certain combinations match to create powerful forms, and said forms have special jingles, while mismatched forms only state the names of the collectibles.
According to director Ryuta Tasaki, Build has the "highest IQ of all the Heisei Riders" as Build is a prodigy in physics.
- Given the statement of being the smartest of just the Heisei Riders, he is seemingly only rivaled in intellect by Kamen Rider 1, who has an IQ of 600 and a major in biochemistry.
Sento is the first Kamen Rider with the rabbit, giraffe, and the hedgehog as an animal motif.
Sento is the third amnesiac protagonist with a mysterious past, after Shouichi Tsugami of Agito and Tsukasa Kadoya of Decade.
Build is the first Kamen Rider since Agito to have certain parts of his body possess different amounts of power (save Ex-Aid's Robot Gamer left arm attachment).
The pneumatic tubes and assembly platform will not appear when Sento doesn't use a Best Match form.
- One of the pneumatic tubes will go invisible if a part of the Best Match is already in use during the change into a Best Match from a Trial Form.
Sento is the first main Heisei Era Rider that has a different color for each eye in all his forms.
HawkGatling Form is similar to Snipe's Combat Shooting Gamer Level 3, as both of them are orange-colored flying forms armed with gatling guns.
Coincidentally, Build's PhoenixRobo Form shares an identical motif with Houou Soldier's mecha, Gigant Houou, from Build's first Super Hero Time partner, Uchu Sentai Kyuranger.
Build's Legend Rider forms work similar to Decade's main ability, with both Riders being able to transform directly into their predecessor Riders.
- Incidentally, Build is also able to transform into Decade as well.
A Ganbarizing exclusive finisher for KaizokuDensha bears similarities to Den-O Liner Form's Densha Giri. ^[14]
Build is the next rider other than Agito to have more than one super form.
