What would you do if you died today, only to wake up completely unharmed moments later? For high school student Kei Nagai, this terrifying realization is the beginning of a nightmare. After a gruesome traffic accident claims his life, Kei discovers he is an Ajin—a rare, immortal being feared by humanity and hunted by the government. Branded a monster and forced to flee the only life he has ever known, Kei is thrust into a cold, calculated war between his own kind and a society that views them as nothing more than lab rats.

This is not your typical supernatural thriller. Ajin: Demi-Human is a masterclass in psychological tension and high-stakes action, exploring the dark corners of morality when survival is at stake. With fluid, cinematic art and a plot that keeps you guessing at every turn, this award-nominated series pits human cruelty against the chilling resolve of those who cannot die. As Kei is dragged into a global conflict built on terror and betrayal, the line between hero and villain begins to blur. Dive into one of the most gripping Seinen sagas ever written, where the greatest threat isn't death, but what you are willing to become to stay alive.
