Terminally-Ill Genius Dark Knight is a psychological fantasy action manhwa written by Jung SeonYul and illustrated by Nagi, following Yoo Chan — a young man diagnosed with a terminal illness whose entire life revolved around a notoriously brutal fantasy RPG. When that game becomes his reality, he is forced to inhabit the body of Nox von Reinharber, the most despised villain of the story's first act.

What sets this series apart is its razor-sharp blend of psychological tension, dark fantasy world-building, and high-stakes adventure. Yoo Chan's deep mastery of the game's lore becomes his only survival tool as he navigates a world that wants him dead — by design. Themes of mortality, identity, and calculated strategy run throughout, making it a standout pick for fans of Solo Leveling, My Death Flags Show No Sign of Ending, and other 'trapped-in-game' or villain-redemption manhwa.

This ongoing series is regularly updated with new chapters and is best enjoyed in high-quality scans in English. Whether you're drawn in by the genius dark knight concept, the terminal illness narrative, or the thrilling RPG survival premise, Terminally-Ill Genius Dark Knight delivers a uniquely compelling read that keeps fans coming back chapter after chapter.
