Seo reigns as the primary antagonist and formidable CEO of OctinQ, a global IT titan shaping Neo San Francisco’s technological landscape. Renowned for his razor-sharp intellect, he punctuates interactions with theatrical English exclamations like “GREAT!” and “EXCELLENT!”—a quirk echoing the eccentric flair of characters such as Dr. Robotnik. Under his leadership, OctinQ weaves itself into the city’s vital systems, from infrastructure to public services, anchoring Seo’s dominance over its daily operations. Beyond boardrooms, he cultivates a refined passion for ceramics, juxtaposing ruthless corporate strategy with artisanal precision. His dealings with rivals and allies alike blend strategic maneuvering with interludes of calculated charm, though the shadows of his past and true ambitions remain veiled. As the series’ conflict unfolds, his corporate empire becomes both shield and weapon in opposing the protagonists’ fight to safeguard the city from emerging threats.
