Terminally Ill Genius Dark Knight (Korean: 시한부 천재 다크나이트) is a premier fantasy manhwa that has captivated readers with its "glass cannon" protagonist and its high-stakes approach to the "Game Transmigration" genre. Produced with the dark, polished aesthetic common to top-tier fantasy webtoons, it excels at creating tension through its unique "limited life" mechanic.

The story follows Yoo Chan, an elite gamer who spent 10 years mastering the notoriously difficult RPG, Inner Fantasia. After achieving the "True Ending," he is transmigrated into the game world as Knox von Reinhaver, a minor villain destined for an early grave. While Knox is blessed with an unprecedented "Genius" talent for dark arts, he is cursed with a terminal illness. Every time he taps into his immense power, his remaining lifespan decreases. To survive, Knox must use his pro-gamer knowledge to rewrite the story, all while managing a body that is a ticking time bomb.
