Frankenstein (Korean: 프랑켄슈타인)
Rai's loyal servant and the principal of Ye Ran High School, Frankenstein is best known for his cheerful demeanor and unwavering devotion to his master. He constantly addresses Rai as "Master" and spent considerable time searching for him after Rai's mysterious disappearance. His shock at discovering Rai in his own school office—dressed in the institution's uniform and freshly awake—kicked off the main events of the story.
Personality-wise, Frankenstein balances his bubbly nature with surprising depth. He can shift into serious, calculating mode when situations demand it, and fans often note his slightly sadistic streak during combat. Despite this, he genuinely cares about the people around him, particularly his students. Rai trusts him enough that he's the de facto authority figure at the school.
Power-wise, Frankenstein is absurdly strong—though Rai sealed away a significant portion of his abilities 820 years ago after he misused them. Only recently has Rai finally lifted this restriction. Interestingly, whenever Frankenstein taps into his full power during serious fights, Rai visibly worries, suggesting Frankenstein's capabilities are genuinely formidable even by his master's standards.
The kids at school tend to call him "chairman."
