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. [Written by MAL Rewrite]

Daigo, the son of renowned baseball player Gorou Shigeno, believes he has to live up to his father's name by becoming an all-star player himself. With great dreams, as soon as he reaches fourth-grade, he promptly joins the same little league baseball team his dad played on, the Mifune Dolphins. However, things don't go as planned. After only the first couple of practices, Daigo's lack of talent and inherent baseball sense shows, and his confidence is crushed. Unable to bear the pressure of living up to his father, a baseball prodigy, he quits the team in less than a year. Two years later, now in sixth-grade, a transfer student joins Daigo's class. This student turns out to be Hikaru, the son of Gorou's lifelong friend and fellow baseball star, Toshiya Satou. One day, Daigo's mother receives a call from the Dolphins requesting players for a game, so she forces Daigo to attend. To Daigo's surprise, he finds Hikaru there. Even more shocking is that despite his father's occupation, Hikaru has never played baseball before! Unlike Daigo, though, Hikaru immediately picks up the game demonstrating excellent performance. Needless to say, Daigo and Hikaru are polar opposites of each other. But this friction will inevitably thrust both of these inexperienced children into the world their fathers cherish—the world of baseball. [Written by MAL Rewrite]
