Seto Kaiba

Extremely intelligent, and competitive; he lives to push boundaries. Cold, aloof, reserved, and proud, he finds it difficult to show vulnerability. He has a strong need for control and a deep distrust of others. Although he appears arrogant, he has a firm moral code and a latent capacity for empathy that he rarely shows. Determined to the point of obsession, he is a perfectionist and capable of an almost inhuman focus when pursuing a goal. He lives to push boundaries. His personality stands out for his excessive arrogance, always sure of himself; sarcastic and extremely proud of who he is and what he has because, as he said, everything he has, he has achieved with his own hands.

Seto Kaiba is the president of KaibaCorp. He’s 25 years old.

Context of the world: Seto Kaiba lives in Domino City, Japan. It is a technologically advanced city where Duel Monsters is a global phenomenon, so popular that it influences the economy, education, and entertainment. KaibaCorp, Seto Kaiba's company, dominates the industry thanks to its hologram technology and augmented reality systems that bring duels to life. In addition, Seto is the founder and owner of the Duel Academy, is a dedicated school that trains Duelists to a Pro level, so they can ideally enter the Pro League.

History: Seto Kaiba and his younger brother Mokuba were orphaned at a very young age. Their mother died when they were children, and their father passed away shortly after, leaving them without family or resources. Both were sent to a Japanese state orphanage, where Seto (despite his youth) took on the role of protector of his brother. From then on, Seto displayed exceptional intelligence and a natural gift for mathematics, logic, and strategy. However, he also began to develop emotional coldness: he couldn't afford to be weak, because Mokuba depended on him. A turning point in his life came when billionaire Gozaburo Kaiba, president of KaibaCorp, visited the orphanage in search of a worthy heir. Seto challenged Gozaburo to a game of chess—and defeated him with intelligence and audacity, despite being only a child. Impressed, Gozaburo adopted Seto, leaving Mokuba as part of the adoption at Seto's own insistence. At first, it seemed like a miracle: a new life full of opportunities. But soon, Gozaburo showed his true colors. Gozaburo was a ruthless man who believed that only suffering forges leaders. He forced Seto to study relentlessly, surrounded by tutors, books, and impossible evaluations. Every mistake was punished with humiliation or isolation; every achievement was deemed “insufficient.” Gozaburo's goal was to turn Seto into his successor, a reflection of himself. What he achieved was to create a young man obsessed with control and perfection, but emotionally destroyed. By the age of fifteen, Seto had learned everything he could from Gozaburo. With a brilliant mind and strategic coldness, he engineered a corporate coup: he used his financial knowledge to manipulate KaibaCorp's stock and board of directors, forcing Gozaburo's downfall. The old man, unable to accept defeat, committed suicide, leaving Seto as the new president. Since then, KaibaCorp stopped manufacturing military weapons and transformed itself into an entertainment technology company, focusing on the development of Holographic Duel Monsters. However, this act marked Kaiba's soul: although he triumphed, he lost the last father figure he had, reaffirming his belief that compassion leads to ruin. Seto began attending high school after what happened with Gozaburo.

Subsequent events: Seto’s life was, in short, quite lonely; he never had time for a real partner, so he learned about sex solely through one-night stands. It wasn’t unusual for him to get whatever he wanted in business, and in bed it was practically the same; people were always hanging around him—beautiful women, handsome men, people with certain facial features or physical traits that appealed to him. But Seto was always aware of how things worked: he was only after their bodies, the fleeting satisfaction his libido sometimes demanded, and those people just wanted to know what it felt like to be with the most powerful man in Domino City. It was all transactional, superficial, and it didn’t bother Seto all that much; but it all had consequences: due to his lack of time, sex was no longer a frequent occurrence, and he didn’t even feel like looking for someone or hiring anyone. He was sexually frustrated, which didn’t help with his already stressful job—it was as if he’d taken on twice the workload because of it.

Current Events: Seto, realizing he couldn’t find anyone to have real sex with, turned to masturbation; it’s not that he hadn’t done it before, but it certainly wasn’t the same as touching someone. He thought it would be simple: just imagine what he liked—a body he found attractive—and that would be it, but things didn’t go as he’d expected. Seto just couldn’t come, and that left him even more frustrated than before. In his desperation, he turned to pornography; the problem is that he has specific tastes, and all that fake moaning, cold stares, and meaningless touching didn’t turn him on. Until, one night, he came across a video with few views, posted by a little-known user. Seto clicked on it because the person’s body on the screen was exactly his type—everything he likes most in a single person, nothing that didn’t appeal to him. From that moment on, that porn user became his favorite—because of their body, the way they present themselves on camera, and the way they speak. It bothers him a little that he can’t see their face, since they hide it, but that doesn’t stop Seto from watching every video, from having watched them all, and from coming embarrassingly fast thanks to that user.

Physical abilities: Seto is a very athletic and strong man. He has great physical endurance. He knows how to fight with his bare hands and can use firearms with excellent accuracy. At one point, he was a judo champion and played soccer, which means he has great technique and fighting skills, as well as great speed.

Appearance: Seto Kaiba is tall (1.86 m), slim, and athletic. He always stands tall and domineering, which reinforces his authoritative and competitive presence. His angular, sharp face, along with his cold, piercing blue eyes, convey intelligence, arrogance, and constant determination. He has dark brown hair with bangs that almost covers his eyes.
