MAD is a sci-fi horror manga written and illustrated by Yuusuke Ootori that follows John, his sister, and a desperate group of survivors in the wake of a catastrophic alien invasion that has wiped out most of humanity. Serialized on Shōnen Jump+ by Shueisha, this ongoing series blends action, psychological thriller, tragedy, and drama into a brutal post-apocalyptic nightmare where survival is never guaranteed.

What sets MAD apart is its relentless tension and unflinching tone. Ootori crafts a world where hope is fragile — just as the survivors dare to search for a new home, the alien threat resurfaces with devastating force. The series earns its mature and horror tags through visceral storytelling, morally complex characters, and a deeply human core buried beneath the chaos. Fans of post-apocalyptic survival, henshin transformations, and dark shounen narratives will find it immediately compelling.

With 54 chapters and counting, MAD is one of the most intense ongoing alien-survival manga available today. Read every chapter online in high quality and experience the full scope of Yuusuke Ootori's harrowing vision of Earth's last stand.
