Noblesse is about a powerful noble - Cadis Etrama Di Raizel (called Rai) - who has been asleep for 820 years with no knowledge of mankind's advancement and scientific successes. He has recently woken up in an abandoned building in South Korea, and is starting to get used to the modern world. He goes to a school where he meets his loyal servant Frankenstein. With Frankenstein's help, Rai enrolls into Ye Ran high school, and inadvertently befriends Shin Woo - an athletic teenager, Ik Han - a computer geek, Yuna - Shin Woo's crush, and a few others. Noblesse follows the group's often dangerous adventures against a secret organization while uncovering Rai's past.
