==History==
===Background===
Gentoku Himuro is the son of Taizan Himuro, who would become the Prime Minister of Touto. He was childhood friends with Koji Hotei since elementary school. Before the Sky Wall Disaster, the two had expressed their interests in politics and wanted to change Japan. During the Martian exploration ceremony, Gentoku arrived in his father's place where he sat beside Yoshiko Tajimi and Masakuni Mido. Suddenly, Soichi Isurugi ran over to activate the Pandora Box, triggering the Sky Wall to raise in Japan, dividing it into three regions, and exposing Gentoku, Tajimi and Mido with a blinding light.
Seven years after the Sky Wall Disaster, Gentoku had been appointed director of the Touto Institute of Advanced Matter Physics. After having Takumi Katsuragi arrested for performing illegal experiments, he later recruited him to continue his Nebula Gas experiments elsewhere. Using resources by Namba Heavy Industries Ltd., Gentoku pressed on to create an underground organization to protect Touto and Japan. After meeting with Soichi Isurugi, Gentoku declared his organization shall be called Faust, deeming that people may view them as devils with their hands in blood as he transformed into Night Rogue.
Within three years following Faust's founding, he was promoted to the position as aide to the Prime Minister of Touto, overseeing research of the Pandora Box. In his time as Night Rogue, he oversaw the human experimentations, including the one that appeared in Sento Kiryu's memories from before his escape, sitting atop a throne. According to Gentoku himself, the reason behind these experiments is to accomplish one of Faust's objectives: to create the "Ultimate Lifeform."
===The Faust Conspiracy===
While Gentoku and his assistant Nariaki Utsumi were interviewed by journalist Sawa Takigawa, he recalls the Sky Wall Disaster and the Touto Institute's objective to decipher the Pandora Box before foreign countries attempt to seize the country. He hires Sento Kiryu to analyze the Pandora Box's energies. When Gentoku later led a group of Guardians to apprehend the escaped convict Ryuga Banjo, he was angered once he escaped with Kamen Rider Build's assistance. Declaring war on both of them, Gentoku as Night Rogue had Banjo's fiancée Kasumi turned into the Burn Smash, knowing that there's no way in saving her.
Using his position as the Touto Prime Minister's aide, Gentoku continually pleads to his father to expand their nation's militia, only for his ideas to be quickly rejected. As director of the Tohto Research Institute, Gentoku continues overseeing the efforts to understand the power of the Pandora Box, and also impart Sento Kiryu information about Takumi Katsuragi and his Nebula Gas experiments. Gentoku as Night Rogue abducted several people to inject them with Nebula Gas. Tantalized with the prospect of the Build Driver, the peak of Takumi Katsuragi's weaponry, he sought to claim the Rider System as Touto's military defense against the other nations.
Night Rogue often comes into conflict with his accomplice Blood Stalk, who has bigger plans for Kamen Rider Build and Ryuga Banjo. Gentoku would often communicate with Juzaburo Namba as Namba Heavy Industries Ltd. has funded for Faust's endeavors. Desperate to militarize the Rider System before the other nations do, Gentoku tried stealing the Pandora Box from the Touto Institute. Despite a setback from with Blood Stalk and Build, he would claim the Pandora Box in Faust's custody. After Taizan had a heart attack and carried by paramedics, Gentoku was appointed as the acting Prime Minister of Touto, much to his amusement. He ensured to do whatever it takes to protect the Pandora Box and maintain his cover, even having his assistant Utsumi taking the fall for him.
Unfortunately, Gentoku's cover was blown away by Soichi Isurugi after Sento uncovered his double-life as Blood Stalk and disclosed of Night Rogue's identity. Gentoku tried manipulating Sento to retrieve the Pandora Box under Seito's custody, but drops his act after revealing Faust's objectives. He continued chasing after Sento and Banjo for the Pandora Box. Due to his grandiose delusions of ruling Japan, Night Rogue is defeated by the Build RabbitTank Sparkling. Taizan arrives in a wheelchair and scolds Gentoku for his involvement with Faust. Before Gentoku was handed over by authorities, he confirms to Sento that he was actually Takumi Katsuragi all along, mocking Sento for being the exact opposite of Katsuragi and that very soon, he'll be on his side.
===The Japanese Civil War===
After Taizan collapsed due to Blood Stalk's secret intervention, Gentoku is still in power as acting Prime Minister of Touto. Despite Faust's apparent dissolution, Hokuto declared war on Touto over the Pandora Box. Sento and Banjo voluntarily assisted Touto's government to protect the nation, but are forced to comply with Gentoku Himuro's orders, finally having the perfect opportunity to utilize the Rider System as a weapon. He discloses to the pair that the six Pandora Panels had ten bottles each and two Panels were divided amongst nations. He later commanded Banjo to use the Sclash Driver against Hokuto's forces, the Hokuto Sanbagarasu and Kamen Rider Grease.
He later realizes Faust is still active in Hokuto with Namba Heavy Industries' support. Furthermore, Nariaki Utsumi is still alive despite his apparent death. Desperate to win the war, Gentoku attempted to order Touto's forces to invade Hokuto without council. When an enraged Gentoku madly proclaimed himself the leader of Touto, this causes a recovered Taizan to renounce Gentoku as his son and sentence him to exile. Furious, Gentoku transformed into Night Rogue and tried to escape with the Pandora Box, but was intercepted by Build RabbitTank Sparkling. Humiliated, Gentoku promised to return with greater power before disappearing.
Gentoku made his way to Namba Heavy Industries in Seito. He demanded Utsumi to turn him into a Kamen Rider, even going as far as to beg on his knees. He would later be imprisoned and tortured for several days. Gentoku was administered with enough with Nebula Gas and succumbed to his feelings of vengeance. His Hazard Level increased above 4.0, allowing him to transform using the Sclash Driver and the Crocodile Crack Fullbottle to become Kamen Rider Rogue. Following the Proxy Battle with Touto and Hokuto, he led the invasion of Hokuto and captured Yoshiko Tajimi. After making his reveal to the heroes, Gentoku promised to make the Devil's Scientist to experience the same hell he went through.
Serving under Masakuni Mido and the nation of Seito, Gentoku stood with the Washio brothers to seize the Pandora Box. Despite the heroes' best efforts to hide the relic's location, Rogue managed to seize the Pandora Box after killing Akaba. Once Touto and Seito arranged a Proxy Battle, Rogue faced Build in the final round. During their battle, Gentoku questioned his opponent's motives for creating a weapon of destruction, and Sento accepts responsibility for his actions, revealing his FullFull RabbitTank Bottle that transforms Build into RabbitRabbit. Rogue tried to gain the upperhand after receiving the RabbitRabbit's data, but did not expect him to change into Build TankTank. Rogue is again defeated by Build once more and led to Touto's victory. In the aftermath, Gentoku was asked by his father to come back to Touto, only to reject his offer and left.
===Road of Redemption===
Although the war between Touto and Seito had come to a close, Blood Stalk decided to press on by raising the Pandora Tower from the Sky Wall. Gentoku would become aware that Masakuni Mido was murdered and replaced by Juzaburo Namba assuming Mido's appearance. While conflicted on Seito launching another invasion on Touto, he was forced to comply due to the chip implanted to his body that could kill him for any sign of betrayal against Stalk and Namba. Despite this, Rogue would secretly help the Kamen Riders during their invasion of the Pandora Tower. Rogue would inform Banjo that it was Stalk's idea to turn Kasumi into a Smash in the first place and quickly informs Sento about Masakuni Mido's death. He allows the Kamen Riders to reach to Blood Stalk's location and reclaim the Pandora Box.
After he freed Kazumi Sawatari's farm workers in defiance, Gentoku was ordered to abduct Taizan Himuro as a hostage. He expressed his shame to his father that he intended to reunify the country, but took his approach very wrong. While trying to smuggle his father out of Stalk's custody, the chip in his body was hindering any chance of escaping. Through Sento Kiryu's assistance, Gentoku's chip was disabled and allowed Rogue the freedom to fight against Stalk and Namba. However, Evolto recovers the Evol-Driver and emerges as Kamen Rider Evol. During a battle between Rogue and Evol, Taizan shields Gentoku from his blast. Being forced to hold his father in his final moments, Gentoku is requested to atone for his crimes and assures him he can reunite Japan. With his father's body lying in his arms, Gentoku screamed as he cried in agony.
With Evolto posing as a larger threat than expected, Gentoku is called upon by Sento for assistance to stop Evolto as he had possessed Banjo. But even the combined forces of Rogue, Build, and Grease weren't able to stop Evol as their foe managed to complete the Pandora Tower. While Kazumi later engaged in a sparring match with Gentoku as he still never forgave him for killing Akaba, he decided to put aside his anger for the time being. Banjo was eventually free from Evolto's influence, only to have possessed Sento instead and can access Evol's Rabbit-based Phase 3 form. Although he initially couldn't help Banjo regain his transformation ability after the latter lost his alien genes, this did not stop Rogue from fighting Evol with Grease and eventually Great Cross-Z.
However, Evolto managed to complete the Evol-Trigger from the Kamen Riders' powers and access his Black Hole form, jettisoning Sento. However, his memories of being Sento are gone and is reverted back into Takumi Katsuragi. Gentoku reunited with his former colleague and apologized for his actions, in which Katsuragi refusing to accept his apologies due to the war Gentoku had a hand in creating. Even after forming a truce with Namba Heavy Industries, the Kamen Riders were no match for Evol Black Hole. Following Nariaki Utsumi's breakdown into Kamen Rider MadRogue, Gentoku expressed shame for bringing his former assistant into a dark path. He continued to beg for Katsuragi's forgiveness, recognizing that while he cannot undo his mistakes, he should at least atone for them. Although Katsuragi left without saying a word, Gentoku's words to him is what allowed him to remember his life as Sento Kiryu and would allow him to become Kamen Rider Build Genius Form.
===Gentoku's Atonement===
With Sento's memories been restored back to normal, Gentoku greets him in the cafe in a set of denim clothes. His sudden fashion sense repulsed everyone in Nacista, with Misora being the most disgusted over the mismatch of clothes that Gentoku wore. He tried to change his style by wearing a set of flashy pink clothes and later a rainbow poncho, both were rejected by Misora. Eventually, Gentoku settled in wearing a black jacket but wearing shirts printed with multiple messages.
Gentoku, now a member of Team Build fights against another invasion by Seito. Following Shinobu Katsuragi's resurface as Evolto's accomplice, Gentoku advises Sento to not let any his hope of father blind him from his actions he committed. This was when Gentoku and Kazumi decided to raid a Faust experimentation site in order to increase their Hazard Levels using the Nebula Gas chambers. While this did increase their strength, the Nebula Gas overdose threatened to damage their bodies, a necessary risk that Gentoku and Kazumi agreed to take. When Sento attempted to fight Evolto alone, Gentoku along with Banjo and Kazumi accompanied him in the ensuing fight with Evolto. In the ensuing fight, Rogue manages to help restrain Evol and allowing Build to unleash a devastating attack on Evolto, this still did not defeat Evolto for good.
Evolto continued to collect the Lost Bottles to complete the Black Panel to evolve into a horrifying new monster form and announcing his intention to destroy Earth. Gentoku would join in Sento's plan to use the White Panel to merge their world with one where the Sky Wall did not exist, using Evolto himself as the catalyst. Shortly after Evolto's national television broadcast, the Kamen Riders raced up to Pandora's Tower. Gentoku stayed behind to fight Evolto's replicants of the Hell Bro's. He was also unexpectedly aided by Utsumi, having feigned his alliance with Evolto. While engaging with Kamen Rider Evol, Gentoku discovered Evolto had converted Utsumi into a cyborg right after Gentoku shot him and MadRogue ended up short-circuiting in an attempt to overwhelm Evol. After making a hasty retreat to the height of the tower, he learnt of Kazumi's death from becoming Grease Blizzard, with Gentoku screaming in sadness over the loss of his friend and comrade.
===Final Battle and Death===
Despite his injuries during the raid of the Pandora Tower, Gentoku joins with Sento and Banjo to charge at Evolto, who was unimpressed at their performance and takes an opportunity to transform back into his monster form. Rogue continued to fight Evolto after he tried to absorb the moon. Gentoku thought back to one of his final conversations with Kazumi, how he forgave him for Akaba's death and believed he had atoned enough for his crimes. Upon hearing the voices of the people, he continues fighting as his Hazard Level increased and deploys a desperate Rider Kick, but to no avail as Evol easily brushes the Rider aside into a nearby pillar. Having exhausted the last of his strength, Gentoku entrusts Sento with defeating Evolto. In his last moments, Gentoku ponders if he had lived up to his dad's legacy before disintegrating into purple embers.
===Legacy===
Thanks to Gentoku's persistence, Evol became paralyzed as Rogue's last attack managed to break the Evol Trigger apart. This allowed Sento to extract the Black Pandora Panel and the ten Lost FullBottles from Evolto, and fuse them with the White Pandora Panel, opening the path for the new world that Sento would build.
===New World===
After Evolto was defeated for good and the new world had been created, Gentoku is still working for his father, the Prime Minister of Japan, as an aide and politician. Gentoku then meets Sawa Takigawa, now a Central Politics and Economics journalist and asks her if they could continue the interview in his office, which Sawa agrees.

===Kamen Rider Heisei Generations Final: Build & Ex-Aid with Legend Riders===
During the Enigma crisis, Gentoku Himoru provided Sento Kiryu information on Kaisei Mogami, a researcher who left the Touto Institute and pursued studying parallel dimensions and the Bugster Virus that was looming in Sky Wall. Soon after, Mogami's plot to smash the two Earths was thwarted by Build's intervention.
===ROGUE===
Gentoku Himoru's backstory is further expanded during the events of founding Faust and his evolution into Kamen Rider Rogue. Before he was aide to Touto's Prime Minister, his childhood friend Koji Hotei assumed the role. Gentoku tried to request Hotei to convince his father to expand Touto's militia to no avail. This led him to founding the Faust with financial backing from Namba Heavy Industries, and cooperating with Takumi Katsuragi and Soichi Isurugi with their knowledge with Pandora Box and the Nebula Gas. Isurugi later kills Hotei to secure Gentoku's position as the Touto Prime Minister's aide. Gentoku becomes Night Rogue to change Japan using the Nebula Gas technology to advance Touto's defenses.
Flashforward to his exile from Touto, Gentoku arrived to Namba Heavy Industries in Seito and demands Utsumi to turn him into a Kamen Rider, even going as far as to beg on his knees. After the new Sclash Driver was created, Gentoku was denied being administered Nebula Gas. He was locked into Namba Heavy Industries' detention facility for those with low Hazard Levels. Blood Stalk had set his sights on Gentoku as the ideal candidate as Seito's Kamen Rider, believing he had strong enough emotion to use the belt, despite Utsumi's denial. While Gentoku endured being beaten senselessly by the other prisoners, this did not take away his desire to become a Kamen Rider and got his wish to undergo the Nebula Gas treatments.
As the experimentation only increased his Hazard Level to 3.5, Gentoku was dragged to an isolated section of the facility to fight the prisoners to the death to increase his Hazard Level. Surmising the possibility of death, Gentoku apologized to Utsumi for his actions. Gentoku engaged the prisoners and managed to held on his own. When Remocon and Engine Bro's entered the battlefield, Gentoku's Hazard Level reached 4. This allowed allowing him to finally transform into Kamen Rider Rogue to vanquish the Kaisers, despite knowing they were his former subordinates, Kakizawa and Matsui, and believed they served their purpose. Rogue's body reached its limit and cancelled the transformation. Gentoku watched Stalk and Utsumi leave as they have much planned for him in the future. As he tried to stand back up, Gentoku claimed he'll free himself someday.
===Kamen Rider Prime Rogue===
One day, Gentoku is forced to go clothes shopping with Misora. While Misora tries to have him dress more conservative, Gentoku continues electing to wear a mismatch of clothes. He also meets a little boy named Sho who wears a black jacket that is too big to fit him, a keepsake of his late father. As the city is being attacked by Kamen Rider Evol and his Hard Guardians, Gentoku decides to use Sento's new power-up item and transforms with the Prime Rogue Fullbottle and the Build Driver to become Kamen Rider Prime Rogue. Gentoku was given Shou's jacket as a token of appreciation but dismayed when Sento reveals that the Prime Rogue Fullbottle would take a month to repair.
===Kamen Rider Build: Be The One===
During the Build Annihilation Plan, Rogue attempted to protect Sento Kiryu from the amassed populace of Japan, who had been compelled to eliminate him, only to be overwhelmed by the angry mob. Gentoku and Kazumi were stripped of his Sclash Driver and kept in confinement before being set free by Nariaki Utsumi, who made them beg to return their Drivers. Making their return, Rogue joined in the final battle against the Blood Tribe with the Kamen Riders and defeated the Scissors Lost Smash.
===Kamen Rider Heisei Generations Forever===

Kazumi and Gentoku later regain their memories again and become Grease and Rogue once more to protect Misora and other civilians from Tid's forces.
===Build NEW WORLD: Kamen Rider Cross-Z===
Sometime after the creation of the New World, Gentoku settled his life as a politician. However, due to the appearance of Killbus, his memories of the previous world were restored once the Pandora Box was reactivated. Reuniting with his allies once more, Gentoku becomes Kamen Rider Rogue and assists Banjo as they battle Kamen Rider Killbus. The next day, Rogue and Grease help Cross-Z defeat Killbus, while holding off the Smash.
===Build NEW WORLD: Kamen Rider Grease===
Gentoku continues to act as the aid to Japan's Prime Minister, Taizan Himuro, and notably shaved his beard. He was presenting to UN Representive, Simon Marcus, regarding the Build Driver with Shinobu Katsuragi. Upon the appearance of the terrorist organization Down Fall, Gentoku battles the group but his Hazard Level was absorbed, rendering him incapable of fighting after a sudden blank point shot from Simon Marcus as a Phantom Crusher. After he was captured by the terrorist group, he called Sawa to overhear the conversation of Down Fall. 
Sawa later finds his location and doses him with a Phantom Liquid elixir to replenish his Hazard Level. Gentoku later teams up with the Kamen Riders to battle the terrorist group as he transforms into Kamen Rider Prime Rogue. After the battle, Sento asked Gentoku why he called Sawa first. As Banjo asked Gentoku what happened to his beard, he revealed Gentoku and Sawa became a couple by showing off their outfit, revealing Sawa is the one who told him to shave.

With Sento's help, this chip was deactivated.
*Nebula Gas Deterioration: Gentoku allowed Faust to dose him with Nebula Gas to increase their Hazard Levels. While this did increase their strength, the dosage threatened to damage their bodies, a necessary risk that he agreed to take.

===Friends===
* Team Build - Teammates and Friends
**Sento Kiryu/Takumi Katsuragi/Kamen Rider Build: Gentoku knew Sento back then as Katsuragi. When Takumi returned as Sento, he didn't recognize him only just another stranger who he hired to research on Pandora's Box. Eventually, learning the truth from Stalk that Sento was Takumi, he immediately called him by his true name. Becoming from Night Rogue to a Kamen Rider, the Nebula Gas changed him back to his normal self from Pandora's Box's light. Knowing how it caused him to go powerhungry and waging war on Hokuto & Seito, using Takumi and Utsumi for his own gain, he wishes to redeem himself for what he's done, joining Team Build. However, Gentoku always calls Sento as "Katsuragi", until his final moments.
**Ryuga Banjo/Kamen Rider Cross-Z (Charge): Once an enemy of Banjo who escaped Faust and later fought him becoming Cross-Z. Banjo accuses Gentoku as the person who killed Kasumi with the Smash experimentations, although Gentoku said that he didn't order it. He didn't know Blood Stalk was actually using Banjo for his Hazard Level to rise, in order to take back his DNA. When Gentoku joins Sento's battle against Evolto, Banjo lost all of his enmity to Gentoku.
**Kazumi Sawatari/Kamen Rider Grease: Both he and Kazumi are like Sento and Banjo. Kazumi and Gentoku were enemies during the Touto-Seito War. After the rebirth of Evolto on Earth, Kazumi fought with Gentoku to make him fight alongside Team Build and to pay him back for not only Akaba's death, but also for his former compatriots killing Kiba and waging war on Hokuto during his time in Touto. Defeated, Gentoku fights alongside them when freeing Sento from Evolto's control. Kazumi is usually annoyed with Gentoku's retro fashion, and they bicker endlessly such as not cooking Kazumi's own special pasta recipe precisely. Kazumi calls him Beard (髭 Hige), and likewise, Gentoku calls Kazumi Potato (ポテト Poteto). However, Gentoku and Kazumi eventually grow friendlier with each other and often fight back-to-back in battles, with Kazumi even forgiving him at last and suggesting him to get back to the government after their battle is over.
**Misora Isurugi: Misora knew Gentoku as Night Rogue and later Kamen Rider Rogue. She hates Gentoku's fashion sense.
**Nariaki Utsumi/Night Rogue/Kamen Rider MadRogue: Once in service to Gentoku, he was shot by him as a means of covering up his tracks as Night Rogue. Seeing him alive, working for Namba left him in shock. Utsumi desired revenge on him for all the life of hell he's been put through. Hearing Gentoku banished from Touto, gave him the opportunity for payback, when Gentoku demanded him and Namba to make him a rider for Seito. When Namba was killed by Evolto, choosing to serve him, Utsumi's vengeance on Gentoku grew when becoming MadRogue. He revealed himself to be getting revenge for Namba's death along with being reborn a cyborg due to Gentoku's actions in his final days. Gentoku thus blames himself for Utsumi's loss of sanity. Later they became allies in the New World, though, Utsumi still appears to express disdain for him being a cyborg caused by Gentoku in the previous world.
===Enemies===
*Evolto/Blood Stalk/Kamen Rider Evol: Gentoku knew Evolto back as Blood Stalk while possessing Soichi Isurugi. He questions his loyalty to him and his motives with Sento and Banjo. Stalk was also the reason he learned of Sento's past identity as Takumi Katsuragi. After being banished by Touto for overthrowing his father as their Prime Minister, Evolto helps turn Gentoku into Seito's Kamen Rider in revenge. Things changed between them after regaining the Evol Driver. Evolto as Evol tried to kill Gentoku, for serving his purpose, but his father Taizan ended up sacrificing himself to save his life. For this, Gentoku vowed revenge.
*Hell Bros - Fu & Rai Washio: The Remocon & Engine Bros, once his allies in Seito, now his enemies after defecting to side with Team Build against Nanba.
*Juzaburo Namba: Once served under him during his time in Touto before joining Seito. Now later enemies after realizing the situation he's in after Namba replaced Mido as him.
*(Kamen Rider) Killbus: Killbus came to the new Earth to destroy it, as he, Kazumi and Banjo stood together to stop him with Evolto's help.
*Keiji Uraga/Kamen Rider Metal Build/Phantom Build: to be added
