Synopsis

Unkillable. Unstoppable. Still hunted. Ji-O, a “Heart Mutant” with the Heart of Resurrection, escaped ten years of brutal experimentation, but freedom doesn’t last. With a body that can regenerate from any injury, he’s a target the world won’t ignore. The moment he finds something worth protecting, and even a sliver of a normal life, it’s threatened all over again by the very lab that tortured him and his friends. But this time, Ji-O is done running. (Source: WEBTOON)
