When Cadis Etrama Di Raizel or Rai, as he is known, awakens after 820 years, he discovers a modern world he simply doesn't understand. Once an extremely powerful member of the Nobles, a race of nearly immortal and powerful creatures, Rai decides to start again as a high school student at Ye Ran High School, founded by his former servant Frankenstein, who is somehow still alive after all these centuries.
