Description
Isaac Ray Pelham Westcott, originally called Ike, spent his childhood in a hidden village of mages with close friends Elliot Baldwin Woodman, Ellen Mira Mathers, and Karen Nora Mathers. Humans destroyed this community out of fear, killing all residents except Westcott and his three companions. Witnessing this massacre ignited a profound change within him, transforming dormant morbid fascinations into core drives. He resolved to create a new world solely for mages, free from humans, a goal central to his future actions.

After the village's destruction, wealthy British parents adopted Westcott. Their later accidental deaths bequeathed him a significant inheritance, providing essential resources. Roughly 30 years before the main events, he worked with Woodman and Ellen to develop the Spirit Formula. This potent sorcery ritual concentrated the world's mana to artificially create the First Spirit. This act simultaneously birthed an adjacent dimension and triggered the catastrophic Great Eurasian Spacequake, responsible for 150 million deaths. Westcott reacted to this devastation with manic laughter, revealing his detachment from conventional morality.

The First Spirit's creation led to the founding of DEM Industries (Deus Ex Machina Industries), with Westcott as director. DEM specialized in Realizer technology, devices derived from studying the First Spirit's Angel, Ain Soph, propelling the company to global prominence. The First Spirit eventually escaped DEM's control, later emerging as Mio Takamiya. Seeking to reclaim Mio, Westcott captured her adoptive sister Mana and killed her adoptive brother Shinji (later reincarnated as Shido Itsuka). This triggered Mio's uncontrolled power manifestation and escape.

Westcott possessed a complex personality rooted in abnormal psychology. From childhood, he derived pleasure from suffering and death, feeling exhilaration during his mother's funeral. This evolved into full sadomasochism; he relished inflicting despair on others and experiencing his own pain. He maintained a facade of charm and intellect to manipulate others, masking his true nature. While forming genuine bonds with his childhood friends, he viewed all other individuals—including loyal DEM subordinates—as expendable tools. He demonstrated particular cruelty: psychologically torturing Spirits like Nia Honjo to induce Inverse states, deliberately offering victims false hope before crushing it, and contemplating extreme methods including sexual torture to break Tohka Yatogami. He framed his goal of world destruction as revenge for humanity's crimes, though internally acknowledged this justification merely served as convenient cover for indulging his desires.

His operations focused on harvesting Spirit powers. He directed Ellen Mathers to capture Spirit Nia Honjo, subjecting her to physical torture to force an incomplete Inverse transformation. This allowed extraction of her Qliphoth Crystal, which Westcott bonded with to acquire her Demon King, Beelzebub. This granted him abilities including instantaneous knowledge acquisition, information sharing through touch, summoning shadow entities, and creating defensive or offensive barriers from pages. Due to the incomplete transformation, Beelzebub lacked its full potential, including future prediction, and remained vulnerable to interference from Nia's Angel, Rasiel.

Westcott systematically manipulated key figures to advance his plans. He minimized punishment for Origami Tobiichi after her defection from AST, recognizing her value as a pilot for the White Licorice combat unit. He orchestrated Tohka Yatogami's Inverse transformation by having Shido Itsuka ambushed, exploiting her despair to awaken her destructive "Demon King" state. His corporate leadership involved brutal suppression of dissent; he allowed DEM directors to vote against him before having Ellen violently eliminate opposition.

Later developments saw Westcott transcend human limits. After losing an arm in combat against Woodman, he acquired additional Qliphoth Crystals, culminating in stealing the powers of the First Spirit, Mio Takamiya. This transformed him into the Second Spirit of Origin, granting godlike abilities and command over three Demon Kings: Athiel, Qemetiel, and Belial. His final confrontation ended in mutual destruction with Mio, though his legacy of chaos persisted through corporate infighting within DEM and the destabilized Realizer industry.
