Within an abandoned building in South Korea lies a white coffin, from which rises Cadis Etrama Di Raizel "Rai"—an unimaginably beautiful, dignified, and noble man. Awakening in this unknown time, Rai must seek out someone he can trust—his loyal companion, Frankenstein. To begin with, Rai attempts to blend into human society by transforming his old-fashioned clothing into the pristine blazer of the nearby Ye Ran High School. As it turns out, the principal of the school is his servant Frankenstein.

After slumbering for the past 820 years, Rai requires Frankenstein's help to adapt to the current age, so Frankenstein enrolls him as a new student in order to help him understand modern society and experience a normal life. Frankenstein's plans, however, soon go awry not only because of the problems stemming from modern society, but also unresolved conflicts from him and his master's troubled past. Left with no other choice, Rai must resort to using his mysterious power to protect those he holds dear.
