Immortal Regis

Immortal Regis is a South Korean manhwa series written by Ga On-Bi and illustrated by Joo Jae-Liu. First serialized in 2007, the series emerged during a period of growth for the Korean webtoon and manhwa industry as it began to gain international traction. The narrative blends elements of dark fantasy and high school drama, centering on a student who finds himself thrust into a supernatural conflict between warring factions of demons, reflecting a broader trend in fantasy manhwa of the era that emphasized gritty character arcs and elaborate battle choreography.

The aesthetic design of the series is defined by its sharp, angular character models and dark, gothic-inspired costume design, which aims to heighten the sense of dread and power dynamics between the supernatural entities. Joo Jae-Liu's art style was intended to capture a balance between youthful protagonists and the imposing nature of the demonic hierarchy they encounter. Upon its release, the series was noted by readers for its distinct visual style and served as a foundational work for the subsequent sequel, Cavalier of the Abyss.
