Description
Isaac Ray Pelham Westcott began life as Ike in a secluded village of natural mages, alongside close companions Elliot Baldwin Woodman, Ellen Mira Mathers, and Karen Nora Mathers. Initially kind and intellectually promising, his psychology fractured following personal losses. The death of his pet evoked unexpected pleasure from his own sorrow, a reaction intensifying during his mother's funeral where he found morbid fascination in the mourners' grief. This pathology remained concealed until humans destroyed the village, fearful of magic. While Westcott publicly cited this tragedy as motivation for vengeance against humanity, internally he welcomed it as justification to unrestrainedly indulge his aberrant desires.

As an adult, Westcott founded and led the global military corporation Deus Ex Machina Industries (DEM), specializing in Realizer technology and CR-Units. He presented a composed, charismatic facade but governed DEM with ruthless authoritarianism, viewing subordinates and allies as expendable instruments. His calm demeanor masked extreme sadomasochism; he derived gratification from inflicting suffering and experiencing his own pain, including forming attachments solely to witness eventual despair and death. Notable manipulations involved psychologically torturing Spirits like Nia Honjo to induce Inverse states and offering victims false hope only to systematically crush it, exemplified by allowing Nia a brief escape before engineering her subsequent despair.

Approximately thirty years before the main events, Westcott collaborated with Woodman and Ellen to develop the Spirit Formula ritual, concentrating the world's mana to artificially create the First Spirit, Mio Takamiya. This act triggered the Great Eurasian Spacequake, killing 150 million people, to which Westcott responded with manic amusement. He later captured Mio for experiments until her escape. When Mio assumed a human life with Shinji Takamiya and Mana Takamiya, Westcott abducted Mana and fatally shot Shinji, provoking Mio's power manifestation and flight. This event indirectly led to Shinji's reincarnation as Shido Itsuka and Mio's distribution of Sephira Crystals to form new Spirits.

Westcott's endgame centered on harvesting Qlipha Crystals from Inverse Spirits. After extracting an incomplete crystal from Nia, he gained the Demon King Beelzebub, granting extensive knowledge absorption and information transfer capabilities. Beelzebub could trap individuals in fabricated narrative worlds (Ashufiriya), nullifying their powers, and summon limitless paper-based soldiers called Nibelcole. Later, Westcott replicated the Spirit Formula on himself, becoming the Second Spirit of Origin. This transformation granted him three Demon Kings mirroring Mio's abilities: Athiel (instant death via dark particles), Belial (reality distortion), and Qemetiel (existence erasure). He utilized these to empower allies like Ellen and Artemisia while neutralizing opposing Spirit abilities.

His final confrontation culminated in a battle against Shido, the Spirits, and Mio. Despite near-godlike power, Westcott engaged Mio directly, resulting in mutual annihilation. His death was momentarily reversed by Kurumi Tokisaki's time manipulation, but he ultimately perished. His childhood friends Woodman, Ellen, and Karen mourned his passing.

Throughout his life, Westcott exhibited an ageless appearance, maintaining a 30-year-old visage despite being approximately 50, an anomaly unexplained by conventional magic or technology that contributed to his unsettling aura. His influence extended globally through DEM, enabling political manipulation and widespread conflict to further his objectives.
