Kazumi Sawatari (猿渡 一海 Sawatari Kazumi)[2] is a 29-year-old[3] resident from Hokuto and the leader of the Hokuto Sanbagarasu. In the earlier stages of the war, he transformed into Kamen Rider Grease (仮面ライダーグリス Kamen Raidā Gurisu), as the Rider representative of Hokuto, and later formally joined Team Build to aid the remaining Riders in their fight against Evolto. After the merging of the two worlds, Kazumi regained his memories after Killbus appeared.


Early Life

According to Sawa's report, Kazumi was once the owner of his family's farm in Hokuto, with Akaba, Aoba and Kiba as his workers. However, as a result of the Sky Wall Disaster, virtually all the farmland in the region was rendered infertile. Rather than lay off his workers, Kazumi used his savings to help his employees and their families. Victory of Tears

One day, Kazumi came across a man named Massugu Ubukata, who was attempting to take his grandmother to a hospital only for his path to be blocked by Hokuto soldiers. Giving the soldiers a beating, Kazumi enabled Massugu to proceed, and his grandmother made a full recovery. Kamen Rider Build: Birth! KumaTV!! VS Kamen Rider Grease!

When Kazumi's resources were depleted, he willingly enlisted himself to be a test subject for Faust to further insure his workers' survival. Kazumi tells Stalk, who was leading the experiment, to lie to the workers by informing them that Kazumi lost his memories as a side effect of the experiment. Victory of Tears

Shortly before Hokuto invaded Touto for the Pandora Box, Kazumi was chosen to lead a strike team in charge of retrieving Touto's Fullbottles and Pandora Box panels. He was given a Sclash Driver by Soichi Isurugi, allowing to become Kamen Rider Grease. Feeling indebted to their boss for his sacrifice, his three workers became Hard Smash, forming the rest of his strike team.

Indebted to Kazumi, Massugu Ubukata wished to join his side and as such, crafted dog tags for himself as well as Kazumi and the Hokuto Sanbagarasu. However, Kazumi initially refused his gift and ask him to go back to Hokuto. Kamen Rider Build: Birth! KumaTV!! VS Kamen Rider Grease!

Reclaiming Hokuto's Fullbottles

"These are Hokuto's Fullbottles so I'm taking them back. But don't worry. I'll see you guys again soon... on the battlefield."

Shortly before the outbreak of the War, Kamen Rider Grease took an expedition to Touto in order to reclaim the Phoenix and Robot Fullbottles for Hokuto. Coming across Touto's Kamen Riders Build and Cross-Z, whom were engaged in battle against a squad of Touto's Guardians, Grease swiftly destroyed the Guardians as he snatched the Fullbottles off Build's person before leaving as soon as he came. Though he did not get a clear look at his assailant, Build correctly deduced that he must be another Kamen Rider. Meanwhile, Grease watched the Riders of Touto from a distance, well aware that he would soon face them on the "battlefield". Kamen Rider Heisei Generations FINAL: Build & Ex-Aid with Legend Riders

Hokuto-Touto War

As Kamen Rider Grease, Kazumi led the Hokuto advance into Touto once war was declared by Prime Minister Yoshiko Tajimi. Penetrating the Sky Wall, Grease destroyed many Touto Guardians. The Weaponry Hero

Ryuga Banjo encountered him as he searched for the Hokuto Sanbagarasu. A Strong Smash Hazard appeared and began attacking bystanders, and as Ryuga put on the Build Driver, Kazumi destroyed the Smash in one punch using his hidden Helicopter Fullbottle before leaving. Later, after Ryuga and Sento had defeated the Hokuto Sanbagarasu in Ryuga's first fight as Cross-Z Charge, Kazumi showed up to challenge them with his own Sclash Driver. Rider Wars Start

One fight with Cross-Z Charge was interrupted by the Sanbagarasu. Stating that they broke the rules, Kazumi relinquished the Kuma and TV Fullbottles to Ryuga. He later caught up with Massugu Ubukata when he was defeated by Sento Kiryu, having exposed himself to Nebula Gas and becoming the Ice Smash. Engaging Build, Grease found himself bewildered by Sento's new KumaTV Best Match. Ultimately, however, Sento learned the story of Massugu and Kazumi through Televi-san, and chose to return the Kuma and TV Fullbottles to Kazumi. Left with Massugu, Kazumi realized that he was still holding on to the dog tags he had made for him and his comrades and finally accepted them, claiming that the jingling sound Massugu made when he walked irritated him. Kamen Rider Build: Birth! KumaTV!! VS Kamen Rider Grease!

Hokuto's Defeat

Hokuto and Touto decided to end the war by having a duel between their respective Kamen Riders. It looked like Hokuto would win because Kamen Rider Build was afraid of using the Hazard Trigger. Ultimately, Build used the unstable Hazard form to win the duel and the war. Little was accomplished, however, as both war-weary countries faced a common enemy in the Seito nation. Victory of Tears

Seito's Uprising

Kazumi during the tournament.

At the end of the Hokuto/Touto war, it became clear that the two nations would have to team up to defeat the Seito nation, who began an aggressive campaign to conquer all of Japan. Soon after, one of the Hokuto Sanbagarasu decided to defend his people from Seito's wrath, and was soon captured by the Washio Brothers, Kazumi had no other choice but to escape back to Hokuto with Akaba, only to be shot down by Fu Washio. Before sacrificing himself, Kiba gave his dog tag to Kazumi. The Kamen Rider then watched helplessly as Kiba died, rationalizing it as just a common occurrence of war. The Phantom of the West

Seito-Touto War

In the final stage of the Seito-Touto war, an arrangement was reached by both governments. Like before, the two nations would pit their Kamen Riders against each other. Build was hesitant to use his full power, as the Nabeshima Family was held hostage. Once Kazumi got the Nabeshima Family out of danger, he watched as Kamen Rider Build use the full power of the Full Full RabbitTank Fullbottle to defeat Rogue and end the war with Seito. The Genius Arrives With a Tank

Opposing Evolto

Grease BTO.jpg

During the Build Annihilation Plan, Grease 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. Along with Gentoku, Kazumi was stripped of his Sclash Driver and kept in confinement before being set free by Utsumi, who made them beg him to return their Drivers. Making their return, Grease and Rogue defeated both the Scissors and Zebra Lost Smash while the leader of the Blood Tribe was defeated by Cross-ZBuild. Kamen Rider Build: Be The One

Final Battle and Death

After Evolto publicly declares to the world of his alter ego and his plan to destroy the earth, Kazumi asks Sento to make a Power-up Item for him, which Sento immediately shows him the completed Blizzard Knuckle, now added with Grease Insignia and North Blizzard Bottle, made with the data of him and Hokuto Sanbagarasu. Sento give Kazumi warning that if he ever uses it to Transform, His Hazard Level would rise beyond human limits and he'll die, thus it's safer to use it as a weapon. Kazumi shrugs that warning off, claiming that his Sclash Driver only had one slot for Fullbottles.

The next day, Team Build meet Evolto at the base of Pandora Tower. After Evolto explained the rule of his game (Team Build must advance hastily to the top of Pandora Tower, and every 10 minutes, Evolto will destroy an Area using a massive Black Hole), they quickly run to the top of Pandora Tower after Transformed. However, they are intercepted by a clone of Akaba, Aoba, and Kiba made by Evolto DNAs. Grease asks the rest of Team Build to leave Hokuto Sanbagarasu Clones to him and to continue to the top without him.

"Sorry, Sento. I broke my promise."
―Kazumi apologizes to Sento for breaking his promise, before transforming into Grease Blizzard[src]

Kazumi transformed into Grease Blizzard.

Halfway during the fight, Grease initially had the upper hand by using Blizzard Knuckle as Weapon, but due to the clones using his former camaraderie feelings against him by mimicking their voices, Grease was defeated. Left with no other choice, Kazumi apologizes to Sento before pulling Shinobu's Build Driver he took earlier from the basement and use it along with the Blizzard Knuckle and North Blizzard Bottle to transform into Grease Blizzard. An Oath to Be The One

Using his newfound power, Grease is now able to regain the upper hand against the Clones. However, Grease's body starts to disintegrate due of reaching his limits. To make things worse, Misora was also there and witnessing Grease impending death. Grease then injects the Castle Lost Fullbottle to prolong his body limit temporarily and announce that this battle will be his last Festival while attacking Hokuto Sanbagarasu Clones vigorously.

The death of Kazumi.

After the clones were all defeated, Grease's transformation was canceled and his body started to disintegrate once more. Kazumi then gives the purified Castle Lost Bottle to Misora and told her to leave him. However, Misora begged for Grease to continue on living tearfully. Delighted, Kazumi then tells her that he'll brag this to his comrades in the afterlife. Misora continues to tearfully call Kazumi 'Grease' while hugging his back frantically while Kazumi held his comrades and one of his dog tags to his chest before he finally disintegrates into golden smoke. Misora fell on her knees, weeping and finally muttered 'Kazumin' in grief.Zero Degree Flames


At the top of Pandora Tower, Misora gives Sento the purified Castle Lost Fullbottle while announcing that Kazumi is now dead. The Nascita Gang were all in shock and disbelief upon hearing the news. Misora was on her knees and was hysterical, Sawa hugged her tearfully, Ryuga punches the wall in grief, Gentoku cries heavily, and Sento clenches the Castle Lost Fullbottle hard. Misora was also shown keeping Kazumi's dog tags as a memento.

When Gentoku battled Evolto to the death, Gentoku remembered what Kazumi said to him during their BBQ dinner, saying that Gentoku should be a politician again and that he was already forgiven for what he did to Kazumi's hometown.

A vision of Kazumi appears as Banjo encouraging Sento as he had his final battle against Evolto.

New World

New Kazumi.jpg

After Evolto was defeated for good and the new world had been created, Kazumi and the rest of the Hokuto Trio were at Nascita, playfully discussing Kazumi's potential bride, saying she was as cute as an idol, and that Kazumi would fall for her "at first sight". Kazumi shrugged it off, stating that he wasn't that desperate until the girl in question arrived. Kazumi commented that the girl was cute and passed out, which then the Hokuto Trio carry him out before Sento walks in.

Other Events

Kamen Rider Heisei Generations FOREVER

Team Build in Heisei Generations Forever.png

Kazumi temporarily reclaims his memories and powers from Build's world as a result of the Imagin Futaros using his powers to grant Ataru Hisanaga's wish of meeting Kamen Riders. Grease and Rogue reunite with Team Build to fend off Another Double and protect the little boy named Shingo he was chasing, though Gentoku loses his memories shortly thereafter. Kazumi later accompanies Shingo and Ataru on their bus ride home, during which the latter comments on Kazumi's resemblance to Otoya Kurenai from Kamen Rider Kiva. Upon reaching the Hisanaga residence, they are attacked again by Another Double and Another Den-O. Grease attempts to fight them off on his own, but is defeated and loses his memories again. With Shingo captured and an amnesiac Kazumi unwilling to fight the monsters, Ataru is disillusioned and decides to simply wait until his "delusion" is over.

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. Kazumi presumably loses his memories for the last time after Another Ultimate Kuuga is defeated and the Hisanaga brothers return to their world and respective time periods.

Build NEW WORLD: Kamen Rider Cross-Z

"That is...."
"Kamen Rider... Cross-ZEvol.
―Kazumi and Gentoku Witnessing the Transformation of Kamen Rider Cross-ZEvol.[src]

Due to the appearance of Killbus, the memories of Kazumi from the old world have eventually merged with this world’s Kazumi due to Killbus using Ryuga Banjo and the white panel of Pandora Box. He, along with Misora, and Sawa, who have just regained their memories from the old world, has been called by Gentoku to go to the government office before Sento arrives to reunite with them to discuss a plan to defeat Killbus. Kazumi and Gentoku help Ryuga battle Killbus and his Smash monsters.Build NEW WORLD: Kamen Rider Cross-Z

Build NEW WORLD: Kamen Rider Grease

Kazumi Sawatari Grease Profile.png

Sometimes after the incident with Killbus, Kazumi visited Misora in a park while making a delusion on his next life whether he will be with Misora. Then, Misora asked Kazumi out on the next day which shocked Kazumi as he didn't think the day would come when Misora asked him to go out with him. Kazumi wore a tuxedo and accompanied Misora on the next full day, giving Misora a gift and confessed his feelings at night. But Misora felt disgusted as she got the gift of her outfit as a net idol during the previous world and explained to Kazumi that she just asked Kazumi to go out shopping to buy a gift for her father, much to Kazumi's shock. The Hokuto Sanbagarasu tried to cheer him up, resulting in Kazumi taking them with him sailing to nowhere with a rubber boat. They got lost on an unknown island for days afterward.

They returned to Japan days after and right during the invasion of the Down Fall. Kazumi and co found a group of the Down Fall attacking their farmer friends and proceeded to transform. The leader of the group transformed into a Phantom Crusher and absorbed Kazumi and co's power with no avail much to their shock and asked the reason of why Kazumi and his friends were able to transform. Kazumi didn't get off what happened to him and beat the group with the parting words to have them learn Japanese since they were in Japan.

Kazumi and co went to Sento and informed them what they had encountered. Kazumi finally noticed that the group was supposed to steal their power so they couldn't transform as Sento and Ryuga had become the victim. Sento demanded the answer of why Kazumi and his co able to do so, but Kazumi didn't know and initially made a joke of it as a power of love. But he cut the joke immediately by telling that Misora rejected him led to a strong despair as Sento enjoyed to tease him for a moment.

When Sawa called to Sento about the Phantom Liquid which empowered the Down Fall, Sento and the new world Takumi learned that Kazumi and his co were able to transform because during their day while getting lost, Kazumi and his co were taking a bath in the spot where Phantom Liquid existed thanks to the light radiation from the world merging during the last fight with Evolto (being told by Akaba). Kazumi initially got tricked by Sento to go to a lighthouse where he took the fake map to where Misora lived while his friends rescued Misora on her working site when Sento learned that Misora would be targeted for the terrorist's next phase.

Kazumi arrived late to save Misora and the Hokuto Sanbagarasu and was also overpowered by Keiji Uraga as Metal Build. Keiji demanded the White Pandora panel or else Misora will die. Sento learned that even if he and the others obtained their power back, with the power that Keiji had, they wouldn't stand a chance. Kazumi demanded to be given power as Takumi and Sento could only empower one person who still could fight. But Kazumi later discarded the power up as it requires the sacrifices of his friends and lied to Sento that he went home.

Kazumi went to face Keiji again but as Grease Blizzard much to Misora's shock, but as Kazumi in the current, the form no longer kills him and it allowed Kazumi to beat all the Phantom Crushers and the latter Metal Build. However, Keiji used the underhand method with the sneak attack of hidden Phantom Crushers toward Kazumi and it made Kazumi drop the panel, giving the chance for Keiji to use the panel to power him up and fuse with the Phantom Crusher, turning into Phantom Build.

Kazumi initially brushed the form by just adding a little adjustment and believed that he won't make Keiji win, but Kazumi underestimated the power of the white panel and it led to his defeat. Ryuga arrived and gave Kazumi the Perfect Kingdom adapter and the Grease Fullbottle. When being asked by Kazumi on the others, Ryuga was only quiet and gave Kazumi the group's pendant name, angering Kazumi to think that they were dead.

Grease Perfect Kingdom Profile.png

Proceeding with the new form, Perfect Kingdom Grease, Kazumi settled the last score with Keiji as Ryuga saved Misora. Despite initially being outperformed, Kazumi's anger raised the Hazard level needed to utilize the Perfect Kingdom's true power and he won against Keiji. After he won the fight, he learned that his friends were still alive. On the next day with the same situation during the first moment when the story progressed, Misora finally asked Kazumi on the date for real.


Kazumi's demeanor alternates between calm and composed to ruthless and hysterical, depending on whether he's fighting or not. Presumably, due to his usage of the Sclash Driver, Kazumi is obsessed with battle and finding a worthy opponent. He is not afraid to use lethal methods, going as far as attempting to deliver a Rider Kick to an untransformed Banjo.

However, Kazumi operates by a certain code: he insists on not targeting civilians as long as they stay out of the way, and decided against taking Build's FullBottles due to him butting in the battle, much to the trio and the Hokuto Prime Minister's dismay. He is also repulsed by Prime Minister Tajimi's plan to send unnecessary reinforcements to invade Touto.

He also secretly cares about his underlings, as he is against the Hokuto Prime Minister and Stalk's idea of giving the Sanbagarasu more power by strengthening them with the Hazard Trigger, knowing that they will die after they are defeated. After the Sanbagarasu become Hazard Smashes, Kazumi was visibly frustrated. This is also shown as Utsumi blackmailed Kazumi to defect from Touto and bring Pandora Box to save his remaining co-workers. Kazumi initially fell to despair since he can't betray his comrades and become relieved after confirming his co-worker's safety first hand.

Having seen people die in front of him before, Kazumi recognizes the seriousness of war, viewing death to be a natural part of a war. Though he was deeply saddened by Aoba's death, he conceded that Aoba knew that his own life was going to be at stake and that he died because he was weaker, though that did not change the fact that he was someone Kazumi cared about. While Kazumi bears no ill will towards Sento, he still resolved to have a fair fight with the latter that would be held in the proxy war between Touto and Hokuto. The only exception to this is Gentoku, as Kazumi states himself that he'll never forgive Gentoku for killing Akaba, although his attitude towards him softened later on as he has "redeemed" himself thus forgiving him.

Since Kazumi is a huge fan of Mii-tan, he quickly loses his will to fight and even allows his enemy to escape if Misora is the one who helped them. It's later obvious that he is in love with Mii-tan, but when Akaba asked him about his apparent crush and the possibility of her being Sento's girlfriend, Kazumi denied it by claiming that Mii-Tan is everyone's idol. Kazumi has also been shown to be restless when he is physically close to Misora, leading to him having inner monologues on how to approach her in a romantic way.

Powers and Abilities


  • Artificially Enhanced Physiology: Kazumi has undergone an experiment from Faust which injected him with a certain amount of Nebula Gas, which has enhanced his physical condition to a certain degree. To be noted that as his Hazard Level increases, his physical condition increases as well. However, instead of mutating into a Smash, the gas retained his body without side effects (though he did feign memory loss in an attempt to distance himself from the Sanbagarasu). His natural Hazard Level is much higher than most, as his Hazard Level starts at Level 4 during his introduction, allowing him to utilize the Sclash Driver to transform into Kamen Rider Grease. In Episode 19, Blood Stalk read his level, and it has risen to 4.2.
  • Fullbottle Augmentation: By using a Fullbottle in his hand without transforming, Kazumi can gain abilities based on said Fullbottle's traits.
    • Helicopter: Allows Kazumi to perform fiery punches. It was first used to defeat a Strong Smash Hazard.


  • Expert Combatant: He has shown that he can fight against and knock out Guardians and guards with ease. He also trained with Ryuga Banjo who was a professional fighter using Fullbottles and managed to keep up with him.

Former Weaknesses

  • Blizzard Knuckle: Initially, after Kazumi allowed Faust to increase his Hazard Level once more, transforming using the Knuckle would prove fatal, as it would increase his Hazard Level further beyond human capacity, thus killing him. However, use of the Knuckle has not shown this side effect in the New World. His body has been shown to be able to maintain its current Hazard Level without any drawbacks. Whether or not this is solely because of his resurrection in the New World, or if Kazumi's bath in Phantom Liquid fortified him to the form's drawbacks, is unknown.

  • Team Build - Teammates and Friends
    • Sento Kiryu: He and Sento were enemies during the Touto-Hokuto war. Feeling guilty for killing Aoba while under the influence of the Hazard Trigger, Sento begged Kazumi to kill him as a means of suicide. But Kazumi rather face him in the proxy battle, regardless of the sin Sento caused unknowingly. After the Hokuto proxy battle, with Seito waging war, Kazumi offered himself to join Team Build against Seito & Evolto, and continue to help them until his death.
    • Ryuga Banjou: He and Ryuga were enemies during the Touto-Hokuto war. However, after they became allies, Kazumi is the only rider to call Ryuga Banjo by his first name while everyone else calls him by his last name, while Ryuga called him Bakazumin (play word of Baka=Idiot, in the early alphabet). After seeing Kazumi as Grease Blizzard, Ryuga becomes angry with Sento because he knows that Kazumi will die after using the Build Driver.
    • Misora Isurugi: Misora as Mii-tan was Kazumi's idol and crush. When he saw her, he almost recognized her, until Sento threw him off for mistaken identity in order to protect her from Hokuto and the other governments. After the proxy battle, hearing her voice and catchphrase from the net, he finally sees Misora as Mii-tan close up, after being fooled by Sento. Joining Team Build, Misora only calls Kazumi "Grease" due of her thinking if she call Kazumi by his real name Kazumin, he'll leave otherwise, much to Kazumi's dismay. Misora is the one who witness Kazumi's death firsthand, and call him 'Kazumin' after he disintegrated. Nevertheless, Misora grieves over Kazumi's death and kept his dog tag as a memento. In the New World, Misora still calls him "Grease". Kazumi went shopping with her to buy something for her dad, thinking it was a date. But even though the Sanbagarasu helped him and getting Mii-tan's outfit, she rejects his feelings, leaving him heartbroken. But returns when Misora was in danger and regaining his love for her. After being saved from Keiji Uraga, they finally start dating for real, much to Kazumi joy.
    • Sawa Takigawa: Although they usually didn't talk much, Sawa usually 'use' Kazumi's fanboy attitude towards Misora to sell Mii-tan related goods in very high price, which Kazumi finally bought anyway. But when it came to a dakimakura she made as a means to stop the quarrel between the riders, it proved to be expensive for him, even though they finally reconciled.
    • Gentoku Himuro: Gentoku and Kazumi were enemies during the Touto-Seito war. Kazumi originally did not forgive Gentoku for what happened to Akaba, including his former compatriots for Kiba's death as well during the Touto-Seito war. Knowing revenge won't bring him and his comrades back, he makes Gentoku fight him in order to work with him and Team Build. Over time, Kazumi's attitude towards Gentoku seems to have softened, with the two of them seemingly bickering with each other a lot, much like Sento and Ryuga. Kazumi calls Gentoku as Beard (髭 Hige), while Gentoku calls Kazumi as Potato (ポテト Poteto). Kazumi would eventually forgive Gentoku, feeling that he has long repaid for his sins, and that he would be able to follow in his father's footsteps. Upon hearing the news about Kazumi's death, Gentoku is seen screaming inaudibly as he is sad.
    • Nariaki Utsumi: Threatened Kazumi into giving Seito Pandora's Box, if he wants his hometown friends saved. But later they became allies in the New World.
  • Hokuto Sanbagarasu
    • Akaba: Akaba, along with Aoba and Kiba is Kazumi underlings during Touto-Hokuto war. They put great respect and care for their Boss, and Kazumi also care of them, albeit not showing it. Akaba is the last Hokuto Sanbagarasu member to die (due of Kamen Rider Rogue). His death makes Kazumi hates Seito and even refused to fight with them when Evol starts attacking.
    • Kiba: Kiba, along with Aoba and Akaba is Kazumi underlings during Touto-Hokuto war. They put great respect and care for their Boss, and Kazumi also care of them, albeit not showing it. Kiba is the second Hokuto Sanbagarasu member to die (due of shielding Kazumi from Engine & Remocon Bros attack). This become Kazumi motivation to join forces with Team Build, since they share the same enemies.
    • Aoba: Aoba, along with Akaba and Kiba is Kazumi underlings during Touto-Hokuto war. They put great respect and care for their Boss, and Kazumi also care of them, albeit not showing it. Aoba is the first of the Hokuto Sanbagarasu to die (due of Build RabbitTank Hazard), and this becoming Kazumi motivation to defeat Sento in Proxy war.


  • Evolto: Known Evolto as Blood Stalk, until becoming his enemy when he revealed himself to have been working for Seito, having them take over Hokuto.
  • Hell Bros: The Washio brothers; Fu & Rai were sent by Seito to control Hokuto. They even killed his comrade Kiba as an example.

Behind the Scenes


Kazumi Sawatari is portrayed by Kouhei Takeda (武田 航平 Takeda Kōhei), who is more previously well known for his portrayal of Otoya Kurenai in Kamen Rider Kiva. As Kamen Rider Grease, his suit actor is Satoshi Fujita (藤田 慧 Fujita Satoshi).


Following Sento and Ryuga, one of the kanji used to spell his name also represents an animal, Sa (), which poetically means "monkey". It could be referring to grease monkey, an English slang term for mechanics.

Grease's incomplete suit

  • Like Cross-Z Charge, Grease's transformation begins with an incomplete suit that lacks the transparent chest piece and faceplate, as well as the spout bag-themed shoulder pads. These elements are formed once Variable Jelly is secreted from several ports on the suit and solidifies.
  • Kazumi is the first Build Rider to use a purely Abiotic item later, followed by Metal Build.
  • Grease Blizzard's left arm is retooled from Kamen Rider Build's Robot half body.
  • In the promotional poster of the movie Kamen Rider Zi-O: Over Quartzer, Grease among other Kamen Riders is seen in the background of the movie poster despite not appearing in the movie.
  • Grease Blizzard was conceived when Kazumi's actor approached producer Takahito Omori to provide the Rider a new form since his character grew popular.[9]
