Isamu Fuwa

Isamu Fuwa (不破 諫) is a captain of the AI intelligence agency A.I.M.S. who transforms into Kamen Rider Vulcan (仮面ライダーバルカン).

Daybreak Accident
The Daybreak Town Accident occurred while Isamu was in class. Following the explosion (which destroyed Isamu's classroom), the boy was hunted by a swarm of rogue HumaGears. The incident caused Isamu to believe HumaGears were designed to kill humans, leading him to despise both HumaGears and Hiden Intelligence, who he believed covered up the incident.

Joining A.I.M.S.
Due to his hatred for HumaGears, Isamu joined the Artificial Intelligence Military Service (A.I.M.S.), eventually becoming the commanding officer. With his excellent fighting capabilities, he fought against A.I.-related violence, especially cases regarding HumaGears. Isamu's recklessness was kept in check only by his colleague Yua Yaiba.

Dangerous Evolution, Assault Wolf
"I don't need any laughter! What I need is...anger! Ever since the Daybreak incident, I lived my whole life full of anger! I will destroy MetsubouJinrai.net! That is...my all!"

- Isamu's resolve of anger to MetsubouJinrai.net, while forcefully opening the Assault Wolf Progrise Key. During the meeting to discuss about Metsuboujinrai group, 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 went to investigate Hiden corps in a suspect that there could be a spy since so far, their move were seemed to be predicted and be advanced a step ahead.

Isamu completely suspected on Spaceman Raiden as the spy after hearing his name, this was later proven to be true which couldn't be believed by Raiden himself because the spy program which was installed to him has made him even unable to notice his position. When Raiden become Kamen Rider Ikazuchi, he defeated Isamu and Aruto when they become Vulcan Punching Kong and Zero One Biting Shark. As the result, all of Isamu's Progrise Keys were taken alongside most of Aruto's by Raiden and were used to create a new and more powerful Progrise Key.

The Progrise Key was finished by Horobi and given to Jin, but Aruto interfered by accessing Zero One Shining Hopper and shot both Jin and Raiden with the newly developed Authorise Buster, making Jin and Raiden dropped their Progrise Keys with Jin only able to take his and Horobi's. Isamu took the Assault Wolf and wondered of why Metsuboujinrai would create a wolf key.

Despite Horobi's warning about the key was only able to be used by Metsuboujinrai, Isamu broke Horobi's expectation by opening the key by force like he always did and becoming the new Vulcan Assault Wolf. Raiden challenged the new Vulcan, only to have a one sided battle with Isamu won, destroying Raiden with the Authorise Buster. Unfortunately, the form had a side effect and made Isamu fell with coughing some blood. Aruto and Izu made their rush on taking Isamu to the safe place.

Personality
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 Progrise Keys 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.

He would later grow even more scornful towards MetsubouJinrai.net due to the Daybreak Town Accident, proclaiming that he doesn't need laughter, only anger.

Fighting Skill
Isamu is trained properly and became an expert in military combat arts. Despite becoming Vulcan which is designed to be a far ranged fighter, Isamu advanced the use for making Vulcan Shooting Wolf even capable to fight properly in close combat. Despite being a person to never make a plan to advance in the fight, Isamu always managed to outwit any opponent mostly as long as they didn't have a better state than him.

Skills

 * 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 Progrise Key's lock and even leading him to adapt Attache Shotgun's recoil after many attempt usage with Vulcan Shooting Wolf which had a weaker power trait than Vulcan Punching Kong.

Weaknesses

 * Assault Wolf: Although this form surpasses the other forms of Vulcan in several ways, this form has an extremely detrimental effect on Fuwa's health, as was seen when its use made him cough up blood and barely be able to walk.

Devices

 * A.I.M.S. Shot Riser - Transformation device and main weapon
 * Progrise Keys - Transformation trinkets
 * Assault Grip - Used to access Assault Wolf

Weapons

 * Attache Shotgun - Vulcan's personal weapon
 * Attache Calibur - Borrowed from Zero-One
 * Authorise Buster - Assault Wolf's personal weapon
 * Assault Rifle - Standard armament of A.I.M.S. squad members; replaced by A.I.M.S. Shot Riser.

Suit-equipped weapons:
 * Knuckle Demolition: Punching Kong's gauntlets.

Allies:

 * Aruto Hiden/Kamen Rider Zero-One: Both Isamu and Aruto have the opposite view 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), 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. 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 Progrise Keys. After Isamu learns of Yua's heavy affiliation with ZAIA, he begins to become more skeptical of her, but they still work well together when the situation demands.
 * Izu: The hatred that Isamu feels towards the HumaGears after the Daybreak Town Accident seemingly extends to Izu.

Enemies:

 * Horobi: After knowing that Horobi is the main perpetrator behind the Daybreak Town Accident, evidenced by the latter's transformation into Kamen Rider Horobi, Isamu now holds great hatred against Horobi. His rage makes him lose his composure and attack him wildly.
 * Jin: TBD

Hiden Intelligence:

 * Jun Fukuzoe: TBD
