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. Frankenstein's goal: to help his powerful, vampire-like immortal master learn about human life and culture as he protects him from the modern forces Rai cannot fathom. But Rai's somewhat peaceful new life is about to be disturbed by The Union, a secret organization interested in using his powers to further their own malicious goals. In Volume 3, Rai struggles to adjust to the modern world, but new threats have emerged in the form of a Union scientist's twisted experiments. Meanwhile, two failed experiments--M-21 and M-24--try to find the identities that the Union stole from them and find unlikely allies in Rai and Frankenstein.
