Vulcan Joseph engineers solutions for a specialized firefighting unit, deploying mechanical ingenuity to aid their operations. Raised in a family of engineers, he honed his skills constructing machines with his father and uncle. Their tragic, suspicious transformation into Infernals ignited his fierce animosity toward Haijima Industries, a corporation he holds responsible for their deaths and systemic corruption. Though distrustful of Haijima-affiliated groups, he allied with the firefighting unit after they shielded him from the corporation’s reach. His striking appearance features short red hair with shaved sides, cyan-blue eyes, and bold striped tattoos spanning his neck, shoulders, and arms. He favors animal-themed attire, including a white "THE ANIMALS" T-shirt adorned with a black paw print, symbolizing his dedication to resurrecting extinct species. On missions, he wears a ram skull mask paired with goggles and a utility-laden toolbelt, merging functionality with his animal-centric ethos. Driven to engineer an energy source superior to Amaterasu, he seeks to eradicate power systems reliant on human sacrifice while reviving lost wildlife. His relentless prototyping involves brutal stress tests—shattering devices with his fists—to guarantee durability. He champions machines as tools, stressing trust in living beings over mechanical reliance. Initially abrasive toward the firefighting unit, he forged brotherly ties with Shinra and Arthur after recognizing their integrity. Yet his hatred for Haijima and figures like Giovanni burns undimmed, fueled by Giovanni’s betrayal of his family, manipulation of allies such as Lisa Isaribi, and sabotage of his projects. A defining mission against a demonic Infernal showcased his tactical growth: collaborating to convert chaotic flames into a directed firestorm proved his shift from solitary inventor to strategic team player. His core resolve—to safeguard loved ones and achieve his energy vision—remains unshaken. His bond with Lisa Isaribi underscores his empathy. He stands by her despite her betrayal, perceiving her as collateral in Haijima’s exploitation. This loyalty mirrors his broader defiance against systems devaluing life, reinforcing his commitment to protect both people and creatures.
