Description
Cadis Etrama di Raizel, often called Rai, is the central protagonist of the story. He is an ancient being known as a Noble, specifically holding the unique and paramount title of Noblesse. This title distinguishes him from all other Nobles, marking him as their hidden protector, their impartial judge, and, when necessary, their executioner. After sleeping in a sealed state for over 820 years, Rai awakens in an abandoned building in modern-day South Korea, completely unaware of humanity's technological and social advancements.

Possessing a stoic, elegant, and seemingly apathetic demeanor, Rai rarely displays overt emotions. His expression is typically neutral, and his manner of speaking is formal and reserved, reflecting his immense age and authority. Beneath this composed exterior, however, lies a deeply compassionate character. He shows great concern for both humans and those under his protection, a trait that drives many of his actions. While his initial regard for humanity may be rooted in the Noblesse's ancient duty to safeguard the weak, his feelings become genuinely personal as he forms bonds with the people he meets in the modern era. A notable source of comic relief in the narrative is his complete unfamiliarity with 21st-century technology, such as mobile phones and computers, and his surprising love for ramen.

Rai's primary motivation is to protect those he comes to care about, including his devoted servant Frankenstein and the human students of Ye Ran High School. Having spent most of his long life in isolation in his mansion on Lukedonia, feared by his own kind and visited only rarely by clan leaders or his one true friend, Muzaka, he yearned for a normal existence. Therefore, he is determined to safeguard the ordinary life he has found, refusing to allow his friends to come to harm. Within the story, he serves as an almost omnipotent force against the various threats that emerge, from secret organizations to rogue Nobles and werewolves. His role is often that of the ultimate arbiter who steps in when the situation escalates beyond the capabilities of others, using his authority as the Noblesse to execute judgment.

His most significant relationship is with Frankenstein, his loyal and powerful human servant who acts as his butler and the principal of Ye Ran High School. Frankenstein, who has served Rai for over eight centuries, is deeply devoted to his master, creating the school to grant Rai the peaceful, normal life he always desired. Rai trusts Frankenstein implicitly but does not hesitate to correct or berate him when necessary, having even sealed Frankenstein's powers in the past to prevent their misuse. Another key relationship develops with the high school students Shinwoo, Ikhan, and Yuna, who give him the nickname Rai. His affection for them is profound; he cannot bear to see them injured and refuses to enter a restorative slumber out of fear that he might never see them again.

While Rai experiences little character change in terms of his core values, he undergoes significant emotional development. Initially a solitary being who spent centuries staring from a window, he gradually becomes integrated into a social circle. His love for the human children and his desire to help displaced individuals like M-21, Tao, and Takeo find a normal life allow him to vicariously experience a sense of belonging he had been denied for millennia. He demonstrates a willingness to forgive those who once tried to kill him, but remains absolutely relentless in punishing anyone who harms his followers or innocent people.

As the Noblesse, Cadis Etrama di Raizel possesses power far beyond that of any other Noble, surpassing even several Clan Leaders combined. However, this immense power comes with a critical weakness: every use of his abilities erodes his life force. This drain has pushed his body to its limit, and the only way to recover is through long periods of hibernation. His notable abilities include physical prowess such as superhuman strength, speed, and flight. He also wields potent mental powers, including telepathy and a form of mind control that can force even powerful enemies to their knees. Among his signature techniques is the Blood Field, a reality-warping domain that allows him to telekinetically crush everything within its bounds. He also possesses other blood-manipulation abilities, such as transforming his own blood into wings or a phoenix for combat. To seal his overwhelming power, he once wore a pair of silver cross earrings, a gift from a previous Lord.
