Noblesse

Cadis Etrama Di Raizel, a Noble of immense power known simply as Rai, wakes from an 820-year slumber into modern-day South Korea. His devoted servant Frankenstein, now the principal of Ye Ran High School, enrolls Rai as a student so he can adjust to the present in relative safety. That safety unravels when agents of the Union, a secret organization built on Frankenstein's stolen research, begin targeting Rai's new classmates.
