Meguru Ukiyo has fallen for his childhood friend, Sara Tatsumi. One day, he stumbles across a white snake that…says it can see the future?! A promising up-and-comer makes a bold serialized debut!

Mysterious immortal humans known as "Ajin" first appeared 17 years ago in Africa. Upon their discovery, they were labeled as a threat to mankind, as they might use their powers for evil and were incapable of being destroyed. Since then, whenever an Ajin is found within society, they are to be arrested and taken into custody immediately. Studying hard to become a doctor, Kei Nagai is a high schooler who knows very little about Ajin, only having seen them appear in the news every now and then. Students are taught that these creatures are not considered to be human, but Kei doesn't pay much attention in class. As a result, his perilously little grasp on this subject proves to be completely irrelevant when he survives an accident that was supposed to claim his life, signaling his rebirth as an Ajin and the start of his days of torment. However, as he finds himself alone on the run from the entire world, Kei soon realizes that more of his species may be a lot closer than he thinks.

After losing sight in his right eye during battle, he's banished to an agricultural facility where he's constantly abused by the commanding officers.

Mine has been a life of much shame. I can’t even guess myself what it must be to live the life of a human being. Plagued by a maddening anxiety, the terrible disconnect between his own concept of happiness and the joy of the rest of the world, Yozo Oba plays the clown in his dissolute life, holding up a mask for those around him as he spirals ever downward, locked arm-in-arm with death. Osamu Dazai’s immortal—and supposedly autobiographical—work of Japanese literature, is perfectly adapted here into a manga by Junji Ito. The imagery wrenches open the text of the novel one line at a time to sublimate Yozo’s mental landscape into something even more delicate and grotesque. This is the ultimate in art by Ito, proof that nothing can surpass the terror of the human psyche.
