"HumaGears hurt humans... They are the enemy of humanity! I will destroy them all!"
―Isamu's hatred of HumaGears[src]

Isamu Fuwa (不破 諫 Fuwa Isamu) is a captain of the AI intelligence agency A.I.M.S. who has a deep hatred for, as they almost took his life as a child. As a member of AIMS, he fights as Kamen Rider Vulcan (仮面ライダーバルカン Kamen Raidā Barukan) to effectively combat the corrupt HumaGears.


Early Life

Past Fuwa In Classroom

A young Isamu following the Daybreak Town Accident.

Isamu Fuwa was born on February 8, 1992. When Isamu was 15 years old, his school was attacked by a platoon of rogue HumaGears coming from the factory following the Daybreak Town Accident. All of his schoolmates were killed, leaving him the lone survivor. Isamu then developed a hostile view towards Humagears and Hiden Intelligence, who he believed covered up the incident.

Joining A.I.M.S.

By the time Isamu turned 27, he joined the Artificial Intelligence Military Service (A.I.M.S.) and became its commanding officer. However with his recklessness a problem, Yua Yaiba was assigned to his team to not only provide technical assistance but to also keep his fiery ego in check.

Horobi's Advance & Isamu Wounded

"You! It was you! So you were the one behind Daybreak!"
―Isamu discovers that Horobi was responsible for the Daybreak Town Accident.[src]
Fuwa and Yua saw Horobi appeared from nowhere with MetsubouJinrai Forceriser as Horobi transform into Kamen Rider Horobi when Fuwa suddenly remember about the Daybreak Town Accident caused by horobi himself as Fuwa attack Horobi blindly. He was warned by Yua but he was seriously injured after Horobi attack him with his Amazing Kaban Shoot and Sting Dystopia as Fuwa immediately lost consciousness.
"Looks like I've got two memories now. A memory of HumaGears attacking me... and one of them saving me."
―Isamu accepts that not all HumaGears are bad.[src]

Fuwa was rushed into hospital after he got injured badly from Horobi's Sting Dystopia and underwent a surgical operation led by Dr. Omigoto. Somehow, the surgical operation was successfully carried out by Dr. Omigoto and Fuwa even thanked Dr. Omigoto for saving him as Fuwa told Aruto that he accept about not all HumaGears are bad.

Dangerous Evolution: Assault Wolf

"I don't need laughter! What I need... is my rage! Ever since Daybreak... I've survived to this day by rage alone! I will destroy! That... is everything to me!"
―Isamu's resolve of anger to, while forcefully opening the Assault Wolf Progrisekey.[src]
During a meeting analysis on, Isamu suspected that there could be two more head members with the name related to Rai and Bou, like Horobi (Metsu) and Jin. Isamu and Yua later went to investigate Hiden Intelligence, suspecting there could be a spy planted in the company to relay vital intelligence.

Isamu and Yua intercepted Artuo, Izu and Spacemen Raiden and Subaru at Hiden Intelligence's space program. Realizing Raiden's name is based from the Rai hiragana, Isamu accused the older model HumaGear to be the spy, but he denies it and butts head with Isamu until Yua and Izu broke them up. As Jin arrives to take their Progrize Keys, Isamu joined Aruto and Yua, transforming into Kamen Riders Vulcan Shooting Wolf, Valkyrie Dashing Cheetah and Zero-One Shining Hopper before engaging Kamen Rider Jin and the Trilobite Magia. Vulcan and Valkyrie dealt with the Trilobite Magia, easily destroying them as Raiden managed to reject Jin's hacking, forcing the MetsuboJinrai Kamen Rider to flee as he commented on Raiden being a survivor of the Daybreak Incident.

Proceeding into the Space Development Center's observatory, Raiden and Subaru revealed Raiden's origin to Aruto and the A.I.M.S. officers. Isamu, however, still believes Raiden to be a spy and butted heads again until Yua and Izu stopped them, prompting Aruto to tell one of his gags. Fighting the urge to laugh and turning off the screen projector, Isamu proclaims he doesn't need laughter in his life and sticking to his gut that Raiden is the spy, forcing the HumaGear brothers to find the lair.

After the brothers located the lair to a dam at Daybreak Town, Raiden lead Isamu and Aruto in the dam's interior, but were stopped by Jin, who was waiting for them and called Raiden "Ikazuchi". Isamu realized he was right until Jin further revealed that Ikazuchi was programmed to slip information to with his knowledge and his failed hacking was a disguise to slip a program to lead both humans to the lair as the older model HumaGear's programming began to falter. Isamu and Aruto watched as Jin placed a MetsuboJinrai Forceriser on Raiden, overriding and restoring his previous programming as he transformed with the Dodo Zetsumetsurise Key into Kamen Rider Ikazuchi.

Angered, Isamu transformed into Vulcan Punching Kong and engaged Ikazuchi, but was outmatched even with Zero-One Biting Shark. As both riders coordinated their attack, Ikazuchi intercepted and electrocuted them, forcing them out of their forms and dropping the Punching Kong, Freezing Bear and Biting Shark Progrisekeys. Reverting to Shooting Wolf, Vulcan fires his Shotriser as Zero-One, transformed into Flaming Tiger, shot jets of flames, but Ikazuchi countered with a Zetsumetsu Dystopia Rider slash with his Valk Sabers, cancelling both human riders' transformations and forcing them outside, which made them drop the Shooting Wolf, Flaming Tiger and Breaking Mammoth Progrisekeys.

As Ikazuchi used the riders' Progrisekeys, with the Sting Scorpion and Flying Falcon keys, to force Satellite Zea to restart the Ark, Isamu watched as Aruto transformed into Zero-One Shining Hopper and fight Ikazuchi until his body reached its limit, which Izu arrived with the Authorise Buster, which Zero-One used to fire the Progrise Dust Rider shooting and overwhelmed Ikazuchi, forcing him to drop the Progrisekeys.

After Izu recovered the human riders' keys and Jin takes back his and Horobi's keys, Isamu watched Horobi arrived and tossed a new Progrisekey with a built-in Assault Grip to Jin, but Zero-One fired another blast, forcing Jin to loose his grip on the new key and Aruto was forced out of his transformed state. Isamu takes the new Progrisekey, noting that it belongs to him as it has a wolf emblem, but Horobi explains it can only be used by members. Ignoring both Horobi and Aruto, Isamu struggles to open the device as he states his anger is his reason for living and will use all his rage to destroy as he opened the key and placed it in his Shotriser, transforming into his new form: Kamen Rider Vulcan Assault Wolf.

Shocking the members, Ikazuchi challenges the new Vulcan, only to become overpowered by Vulcan's new form. Despite his new power, Vulcan surmised Ikazuchi won't go down easily until Aruto handed Vulcan the Authorise Buster, forcing Ikazuchi back even more. Inserting his Punching Kong key, Vulcan fires a Punching Buster Dust Rider shot, which overpowered Ikazuchi's Zetsumetsu Utopia attack and destroyed him. Vulcan then proceeded to fight Horobi and Jin until his body reacted to the form's power, cancelling Isamu's form and making him cough up blood, forcing Aruto and Izu to drag him to safety. Far from, Isamu pushes Aruto aside and proceeded back to's lair, determine to finish the terrorist group once and for all. We are the Astronaut Brothers!

"When I say I'll do it, I'll do it! That's my rule!"
―Isamu's quote when he does things his way.[src]
Gruff and serious in demeanor, Isamu is shaped by his burning hatred for HumaGears. Stemming from his trauma during the Daybreak Town Accident, Isamu believes that HumaGears are designed to kill humans, and is thus obsessed with destroying them. To this end, he will readily dismantle any rampaging HumaGear he finds, often ignoring the orders of his colleagues to do so. His recklessness and short temper are kept in check by his combat experience. He chooses to go by his own rules while engaging Magias, as shown when he forcefully opens his Progrisekeys without Yua's authorization since the latter refuses to give it.

Isamu is openly scornful towards Hiden Intelligence, whom he believes covers up attacks related to HumaGears. This hostility extends to its current CEO, Aruto Hiden. However, his view towards HumaGears eventually started to soften a bit after he learned the truth of the incident, thanks to Anna resisting the transformation into a Trilobite Magia to show the records of the Daybreak City Accident, and more after his life was saved by Dr. Omigoto. Ironically, while generally antagonistic towards Hiden Intelligence and its staff, he's actually fond of Aruto's lame jokes (being the only one who appreciates them) and tries his best not to laugh.

The more he learned about the more he grow even more scornful towards it due to the Daybreak Town Accident, proclaiming that he doesn't need laughter, only anger. However after the destruction of the terrorist, he openly admitted to Yua that he felt awkwardly in peace and has no more hatred against them. He even said himself for being stupid to get angry only to the robot who only follow orders while looking at the immobilized Horobi.

After the incident of was over, Isamu became completely soft but still retain his hard-headed personality on every injustice deed he encounter. Isamu even helped Aruto not as AIMS personal soldier, but as himself, going far to be his moral support about Humagear, showing that Isamu has completely losing his hatred to HumaGear as long as they are not malicious.


Fighting Skill

Isamu is a skilled fighter and is trained in the military combat arts. Despite Vulcan originally being a ranged shooter, Isamu is able to utilize Vulcan's abilities in close-quarters combat. Isamu is also able to fully outwit his opponents despite going into battles without prior battle plans.


  • Marksmanship: It has been shown that Isamu is an expert in firearms, since he is capable of firing without failing his target either long or short distance.
  • Peak Human Strength: Isamu trained hard enough to have a powerful body enough to break the locks over the Progrisekeys and even leading him to adapt Attache Shotgun's recoil after many attempt usage with Vulcan Shooting Wolf. Isamu is also strong enough to be capable of ripping off the Zero-One Driver from a rampaging Metal Cluster Hopper Zero-One.


  • Assault Wolf Progrisekey (formerly): Although this form surpasses the other forms of Vulcan in several ways, this form has an extremely detrimental effect on Fuwa's health, as seen when its use made him cough up blood and be barely able to walk. He eventually managed to overcome these limitations owing to the Assault Grip gaining new data from the Shining Hopper Progrisekey.


Shooting Wolf

Shooting Wolf

"Shotrise! Shooting Wolf! The elevation increases as the bullet is fired.[1]"
―Transformation announcement[src]

Rider Statistics[2]

  • Rider Height: 197.2 cm
  • Rider Weight: 95.6 kg

Ability Parameters[2]

  • Punching Power: 10.5 t
  • Kicking Power: 27 t
  • Maximum Jump Height: 16.2 m
  • Maximum Running Speed: 100 m per 2.9 seconds

Shooting Wolf (シューティングウルフ Shūtingu Urufu) is Vulcan's wolf-based primary form, accessed by using the Shooting Wolf Progrisekey in the A.I.M.S. Shot Riser.

Compared to Zero-One's Rising Hopper form, this form has higher punching power and running speed, but is far outclassed in terms of both kicking power and jump height. It makes up for these weaknesses, however, by being specialized for long-range combat.

Shooting Wolf is composed of the following parts:

  • Wolf Head (ウルフヘッド Urufu Heddo) - The helmet.
    • Wolf Border (ウルフボーダー Urufu Bōdā) - The blue section on Vulcan's forehead area. It is equipped with an auditory sensor and a radar system, giving Vulcan excellent tracking ability. Additionally, it can improve accuracy of shots by sending obtained information toward the Shooting Leader program located within the Wolf Breast chestplate.
    • Wolf Border Ears (ウルフボーダーイヤー Urufu Bōdā Iyā) - The 'wolf ears' attached to the Wolf Border. They are sophisticated auditory devices that can track up to 26 targets simultaneously within a 5km radius by detecting their sound patterns.
    • Wolf Border Hair (ウルフボーダーヘアー Urufu Bōdā Heā) - The blue and red 'hair' located on the sides. Each 'hair' panel houses a type of reflector antenna that forms a beam. By changing the angles of each hair panel, the antennae patterns can be changed as well, allowing Vulcan to collect a wide range of information on his surroundings.
    • Vulcan Face (バルカンフェイス Barukan Feisu) - The white faceplate. It has a built in respiratory filter that removes impurities from the surrounding atmosphere, allowing Vulcan to breathe (akin to a gas mask). It is extremely strong, and can withstand 200 meters of water pressure.
    • Vulcan Optical Visor (バルカンオプティカルバイザー Barukan Oputikaru Baizā) - The blue compound eyes. It not only allows Vulcan to see at a 160° viewing angle at eight times the visual acuity of normal humans, but also allows him to see it in night vision or shading. Additionally, by synchronising with the A.I.M.S. Shot Riser and the Wolf Breast chestplate's Shooting Leader program, Vulcan can shoot targets precisely, with a margin of error of 0.05mm for targets within a 3 km radius.
    • Base Act Head (ベースアクトヘッド Bēsu Akuto Heddo) - The overall helmet. It is part of the Rise Base Actor. It is composed of Zain Ceramic (ザインセラミック Zain Seramikku) armor and is reinforced with a laminated exterior. It is equipped with many sensors. Furthermore, it is highly adaptable, able to change its abilities according to what Progrisekey is used.
    • Base Act Communicator (ベースアクトコミュニケーター Bēsu Akuto Komyunikētā) - The 'ears'/communication devices. Located to the left and right of the Base Act Head, it integrates wireless communication devices and speakers to communicate with outside forces.
  • Rise Base Actor (ライズベースアクター Raizu Bēsu Akutā) - The bodysuit; more specifically the white/silver areas. It is composed of Zain Ceramic armor and is reinforced with a laminated exterior. It is equipped with many sensors. Furthermore, it is highly adaptable, able to change its abilities according to what Progrisekey is used.
    • Base Act Arm (ベースアクトアーム Bēsu Akuto Āmu) - The left arm. Due to it being a part of the Rise Base Actor, it amplifies the wearer's arm strength, allowing Vulcan to lift up to 4 tons.
    • Base Act Grab (ベースアクトグラブ Bēsu Akuto Gurabu) - The left hand. Punching power is amplified and the Paw Pad Connector (パウパッドコネクタ Pau Paddo Konekuta) located on the palm synchronises with the A.I.M.S. Shot Riser as well as the Vulcan Optical Visor.
    • Base Act Leg (ベースアクトレッグ Bēsu Akuto Reggu) - The left leg. Strengthens kicking power and improves running power.
    • Base Act Boot (ベースアクトブーツ Bēsu Akuto Būtsu) - The left foot. Jumping power is enhanced thanks to the Paw Pad Soles (パウパッドソールによ Pau Paddo Sōru)
  • Wolf Breast (ウルフブレスト Urufu Buresuto) - The chest armor. It is equipped with a shooting control system dubbed Shooting Leader (シューティングリーダー Shūtingu Rīdā) that controls the operation of Vulcan's equipment, including firearms, searching, capturing and tracking, and the launch trajectory of bullets to maximise efficiency. In addition, the Wolf Breast has two programs that switch between each other to suit a situation; Frac Wolf (フラックウルフ Furakku Urufu) for operational behaviour and Alone Wolf (アローンウルフ Arōn Urufu) for infiltration operations.
  • Wolf Shoulder (ウルフショルダー Urufu Shorudā) - The blue right shoulder piece. It is equipped with a Howling Canceller (ハウリングキャンセラー Hauringu Kyanserā) device that counteracts the recoil of a shot, reducing damage to Vulcan.
  • Wolf Arm (ウルフアーム Urufu Āmu) - The right arm. Compared to the Base Act Arm, the Wolf Arm's agility is greatly enhanced.
  • Wolf Gauntlet (ウルフガントレット Urufu Gantoretto) - The right forearm armor. Allows Vulcan more accurate shots by utilising a sighting device located within the Wolf Breast and incorporating the data.
  • Wolf Grab (ウルフグラブ Urufu Gurabu) - The right hand. It is capable of fine finger movements, able to capture and lock on an enemy within 1/30 of a second. In addition, it is covered with a special armor made of carbide steel dubbed ZIA209-03 (「ZIA209-03」) in the shape of a wolf claw, allowing Vulcan to slash enemies at super close range.
  • Wolf Leg (ウルフレッグ Urufu Reggu) - The right leg. It incorporates a gyro stabiliser, allowing Vulcan to remain a stable posture when shooting and/or running.
  • Wolf Greave (ウルフグリーブ Urufu Gurību) - The lower right shin armor. Somehow allows Vulcan more accurate shots by utilising a sighting device located within the Wolf Breast and incorporating the data.
  • Wolf Boot (ウルフブーツ Urufu Būtsu) - The right foot. It is covered with a special armor made of carbide steel dubbed ZIA209-03 in the shape of a wolf claw, which not only increases the power of kicks, but also acts as a type of weight that allows Vulcan to remain stable when shooting.

This form has six finishers:

  • A.I.M.S. Shotriser finishers:
    • Shooting Blast (シューティングブラースト Shutingu Burasuto): Vulcan fires 4 blue energy constructs of wolf heads from the Shotriser that attach to the enemy's limbs and crash it into a nearby surface, followed by the energy heads transforming into energy pins and securing the target in place. Vulcan then charges the Shotriser and fires a ball of blue energy that can melt through anything in its path, including the enemy.
    • Shooting Blast Fever (シューティングブラーストフィーバー Shutingu Burasuto Fībā):
  • Attache Calibur finishers:
    • Kaban Strash (カバンストラッシュ Kaban Sutorasshu): Through the use of a Progrisekey, Vulcan can boost his Kaban Strash attack.
      • Shooting Wolf​: Vulcan swings the Attache Calibur and creates two blue energy constructs of wolf heads that attach to the enemy's limbs and crash it into a nearby surface, followed by the energy heads transforming into energy pins and securing the target in place. Vulcan then jumps into the air and spins like a buzzsaw before delivering a downward slash to the enemy as he falls to the ground.
  • Attache Shotgun finishers:
    • Kaban Shot (カバンショット Kaban Shotto): Through the use of a Progrisekey, Vulcan can boost his Kaban Shot attack.
      • Gatling Hedgehog​: Vulcan unleashes a rapid-fire volley of energy hedgehog quills in an arc.
      • Punching Kong: Vulcan shoots a energy construct resembling the Knuckle Demolition.
    • Gatling Kaban Buster (ガトリングカバンバスター Gatoringu Kaban Basutā): Vulcan shoots a mass of energy hedgehog quills into the air, which home in on the enemy and pierce it.

  • Punching Power: 47.3 t
  • Kicking Power: 22.9 t
  • Maximum Jump Height: 8.5 m
  • Maximum Running Speed: 100 m per 3.1 seconds

Punching Kong (パンチングコング Panchingu Kongu) is Vulcan's gorilla-based form, accessed by using the Punching Kong Progrisekey in the A.I.M.S Shot Riser.

This form grants Vulcan an extreme increase in punching power, but a moderate decrease in all other stats. Using Punching Kong also minimizes the Attache Shotgun's recoil.

Punching Kong is composed of the following parts:

  • Kong Head (コングヘッド Kongu Heddo) - The helmet.
    • Kong Border (コングボーダー Kongu Bōdā) - The red section on Vulcan's forehead area. A multi-faceted armor shape with Kong Border Arm and priority for reinforcement for fighting increases the strength of the entire head.
    • Kong Border Ram (コングボーダーラム Kongu Bōdā Ramu) - The forehead. It is a fighting fighting equipment that makes use of the hardness of a special armor made of carbide steel dubbed ZIA209-03 (「ZIA209-03」), and its shape protruding at an acute angle functions as an impact angle and at the same time increases the strength of the forehead.
    • Vulcan Face (バルカンフェイス Barukan Feisu)
    • Vulcan Optical Visor (バルカンオプティカルバイザー Barukan Oputikaru Baizā) - The blue compound eyes. It not only allows Vulcan to see at a 160° viewing angle at eight times the visual acuity of normal humans, but also allows him to see it in night vision or shading.

    • Base Act Boot (ベースアクトブーツ Bēsu Akuto Būtsu)
  • Kong Breast (コングブレスト Kongu Buresuto) - The chest armor. The surface layer of heavy armor that can withstand direct hits from tank guns is space armor, with space between the armor. Resonating the front of the armor by drumming generates acoustic shock waves that prevent physical attacks.
  • Kong Shoulder (コングショルダー Kongu Shorudā) - Six superconducting servo units and linear cylinders built in to the left and right produce ultra-high torque. This gives the wearer super power that can easily handle the heavy-weight Knuckle Demolishion (ナックルデモリション Nakkuru Demorishon).
  • Kong Arm Guard (コングアームガード Kongu Amu Gado) - The upper armor. In addition to protecting the upper arm with heavy armor, it has the role of transmitting super power by connecting the shoulder and forearm.
  • Knuckle Demolition (ナックルデモリション Nakkuru Demorishon) - The gauntlets. It is good at physical destruction by blow using the hardness of carbide steel ZIA209-03 (「ZIA209-03」) and the mass of 150kg on one side. In addition, it can be ejected as a kinetic energy bullet by injecting charged energy, and not only close combat but also the middle range is used as a range, and by using it as a propulsion device, the mobility reduced by weight is compensated.

This form has four finishers:

  • A.I.M.S Shot Riser finisher:
    • Punching Blast (パンチングブラースト Panchingu Burasuto): Vulcan charges his gauntlets with scarlet energy before firing them off to punch the enemy into the air.

Suit-equipped weapons:

  • Knuckle Demolition: Punching Kong's gauntlets.



  • Aruto Hiden/Kamen Rider Zero-One: Both Isamu and Aruto have opposite views regarding HumaGears. While Aruto believes HumaGears are the dream of humanity, Isamu views HumaGears as nothing more than killing machines. Initially, Isamu didn't know about Aruto's alter-ego as Zero-One and called him Grasshopper Jerk (バッタ野郎 Batta Yarou), but the young CEO would eventually reveal his identity by transforming into Zero-One in front of his eyes, in order to prove his honesty. Isamu's views towards HumaGears soften up after his life was saved through a medical procedure by a HumaGear, and became more cooperative towards Aruto and Hiden Intelligence, despite Yua going back to ZAIA. Despite their tense relationship, he's fond of Aruto's lame jokes and is the only one who appreciates them, though he tries to keep this to himself.
  • Yua Yaiba/Kamen Rider Valkyrie: Despite being assigned to the same team, Isamu and Yua actually don't get along and often argue, mostly due to Isamu's rebellious and insubordinate behavior, which causes her to deny him authorization to use the A.I.M.S. Shot Riser and any of his Progrisekeys. After Isamu learns of Yua's heavy affiliation with ZAIA, he began to hold suspicious with her affiliation with Gai, but they still work well together under pretense.
  • Izu: At first Fuwa felt a certain hatred towards the HumaGears, because of the Daybreak Town Accident that had happened that apparently extended to Izu, but little by little he overcame that hatred to the point that he considers her as an ally, such a point that it was she who warned him about what Yua could be doing along with Zaia Enterprise. On the other hand, despite now working together, Izu sees Fuwa's wild and reckless nature and compares it to a gorilla, much to Fuwa's outrage.


  • Horobi: After knowing that Horobi is the main perpetrator behind the Daybreak Town Accident, evidenced by the latter's transformation into Kamen Rider Horobi, Fuwa now holds great hatred against Horobi. His rage makes him lose his composure and attack him wildly. Although he was surprised along with Jin that he was able to use the Assault Wolf Progrisekey despite the fact that only the members could use it. Fuwa finally got his revenge after Horobi took the Rider Kick meant for Jin, thus decommissioning the rogue HumaGear.
  • Jin: Although there was not much interaction between them, Fuwa considers him as an enemy for being a member of After Jin was destroyed by Zero-One Shining Assault Hopper, Fuwa is relieved.

Hiden Intelligence:

Zaia Enterprise:

  • Gai Amatsu/Kamen Rider Thouser: Fuwa suspects Gai and his company of what he might be trying to do. After seeing that Yua, is affiliated with Gai has a fight with her but before defeating her Gai appears considering him now an enemy.

Behind the Scenes


Isamu Fuwa is portrayed by Ryutaro Okada (岡田 龍太郎 Okada Ryutaro). As Kamen Rider Vulcan, his suit actor is Kosuke Asai (浅井 宏輔 Asai Kōsuke).


  • Kamen Rider Vulcan's name comes from the M61 Vulcan, a gatling gun employed by the military. Vulcan is also the Roman name for the Greek god Hephaestus.

  • Kamen Rider Vulcan Assault Wolf Concept Art


  • On every Zero-One episode when Aruto often make a joke, somehow Fuwa always tried to not to laugh in the front of aruto but makes funny reaction from Aruto's bad jokes.
  • Despite Isamu's hot blooded attitude and cold personality, Izu directly questions him: Are you really a gorilla? (あなたはゴリラですか? Anata wa goriradesu ka?). Referencing on Isamu's usage on the Punching Kong Progrisekey, which outrages him with an awkward reaction in front of Izu.Objection! That Trial
    • Coincidentally, "Are you really a gorilla?" Meme was spreaded and goes viral on the internet by some of Kamen Rider Zero-One fan due to the popularity of "Are you really a gorilla" Scene, and even the meme itself was reviewed by Isamu's Actor on one of his Youtube video after Zero-One Episode 21 aired.[7]
  • Somehow, Fuwa also forcefully opens His Progrisekey when he use it for the first time:
    • Shooting Wolf Progrisekey in Episode 2.
    • Punching Kong Progrisekey in Episode 4.
      • The low reverb pitched version of Punching Kong jingle sound can be heard in the scene of Episode 21, where Fuwa is angry at Izu when she directly questions him: Are you really a gorilla?.
    • Assault Wolf Progrisekey in Episode 14.


  • Isamu transforms with the Shotriser in its Gun Mode and opens his Progrisekey by force prior to inserting it, whereas Yua transforms with it in its Belt Mode and opens her Progrisekey after inserting it.
  • While not the first Rider with a wolf/werewolf motif, Vulcan is the first to have it as the motif of his main form.
    • He is also the first Secondary Rider of the Reiwa era where his upgrade form is accessed in a similar matter to the main rider, something that was used in both phases of the previous era.
  • Isamu's motivation to eradicate all HumaGears, both good or bad, is similar to Go Shijima's prejudice against the Roidmudes.
    • Him being present in a tragic incident as a child along with the main protagonist is similar to Hiryu Kakogawa being there along with Sougo Tokiwa from the previous season. Unlike Hiryu, Isamu is not openly hostile towards Aruto.
    • Unlike Go, Isamu become more open after he accepted the fact of good HumaGears after his life had been saved.
  • Isamu is the first Secondary Rider to be injured after using his Rider Shooting during the form's first debut.
  • Isamu often strikes the bullet with his left hand when transforming. A cross (straight punch) for Shooting Wolf and a backhand for Punching Kong.
    • When transforming for Assault Wolf, he catches it in his left hand.
  • Isamu's hot-blooded and hostile personality paired with his occupation brings to mind Keiichiro AsakaIcon-crosswiki (Patren 1gou) from Kaitou Sentai Lupinranger VS. Keisatsu Sentai PatrangerIcon-crosswiki.
    • Isamu's dynamic with Yua is similar to the dynamic between Keiichiro and Tsukasa MyoujinIcon-crosswiki.
  • Isamu’s surname, Fuwa (不破), is also a homophone to the name of the fairy Fuwa (フワ) from Star☆Twinkle Pretty Cure, which airs alongside Zero-One. This fact is implicitly acknowledged by Isamu’s actor on some of the song cover videos on his YouTube channel, where he has a Fuwa plush on his music stands.
  • Vulcan Assault Wolf's helmet uses pieces of Kamen Rider Build RabbitTank Form's helmet.
  • Like Kamen Rider GeizRevive, Vulcan Assault Wolf puts a strain on Fuwa's body to the point that he will cough out blood.
