Loid Forger operates primarily under the codename "Twilight" as a master spy for Westalis's intelligence agency, WISE (Eastern-Focused Division). He deliberately discarded his true name and original identity upon joining, severing ties to a traumatic past rooted in childhood during the Westalis-Ostania war. Growing up in Luwen, Eastern Westalis, he survived an Ostanian bombing at his friends' hideout only because he left early, burdened by guilt after lying to his strict, pacifist-leaning father for money to buy toy soldiers. His father vanished during that attack, and a subsequent air raid in Kielberg killed his mother, leaving him orphaned. These losses fueled a deep hatred for Ostania, driving him to enlist in the Westalian army at 16 under the false identity "Roland Spoofy." Combat experiences, including the loss of childhood friends in a botched operation and an encounter with an Ostanian deserter, reshaped his worldview. He recognized his ignorance about the war's causes as a weakness, ultimately compelling him toward intelligence work with the goal of creating a world "where children don’t need to cry." He underwent rigorous training under Sylvia Sherwood at WISE, evolving into a coldly efficient operative renowned for completing high-risk missions across Ostania for over a decade. As Twilight, he excels through exceptional physical prowess, analytical intelligence, and mastery of disguise. His skills encompass hand-to-hand combat, marksmanship, multilingualism, lock-picking, bomb disposal, and the flawless emulation of targets' appearances and mannerisms. An eidetic memory allows rapid recall of vast information, from classified codes to the dietary habits of 200 penguins. His methodology prioritizes logic and emotional detachment, often employing deception, exploitation, or manipulation to achieve objectives. However, he maintains a moral code: avoiding unnecessary killing, refusing to endanger civilians, and showing compassion toward animals, like disarming a bomb strapped to a dog rather than shooting it. This pragmatism extends to his personal life, where he views relationships as transactional mission tools. His current long-term mission, Operation Strix, requires infiltrating elite social circles to surveil Ostanian politician Donovan Desmond, necessitating a credible family facade. He adopts Anya Forger, an orphan from a dubious institution, believing her ability to solve crosswords indicated academic promise suitable for Eden Academy enrollment, unaware she is a telepathic test subject. He later marries Yor Briar, a city hall clerk seeking marital cover to avoid suspicion as a single woman, equally unaware she is the assassin "Thorn Princess." Initially viewing both solely as mission assets, he plans to dissolve the family post-operation while ensuring their financial security. Early interactions with Anya involve strict academic drilling, frustration over her poor grades, and confusion at her emotional outbursts, reflecting his inability to understand children. With Yor, he maintains emotional distance, treating dates or gestures like gift-giving as strategic performances to uphold their cover. Living as Loid Forger fundamentally alters his emotional landscape. His commitment to the mission clashes with growing, unacknowledged attachments. He displays protectiveness beyond operational necessity: rescuing Anya from kidnappers despite planning to replace her, violently assaulting a school interviewer who humiliated her, and training their precognitive dog Bond as a family guard. He adapts his parenting style for Anya, shifting from harsh drills to patient encouragement after Yor's intervention, and comforts her with affectionate head pats. With Yor, he lowers his guard, sharing personal war trauma to affirm her place in the family and experiencing uncharacteristic reactions like blushing during intimacy or anger when she is insulted. Exhaustion from maintaining his spy persona surfaces during family milestones, like collapsing from relief after Anya's exam success. While encouraging Yor's friendship with Donovan Desmond's wife, Melinda, as a new avenue for Operation Strix, he internally grapples with guilt over manipulating her. These developments highlight an ongoing conflict between his spy ethos of emotional suppression and his authentic, albeit reluctant, embrace of familial bonds.
