In ancient Disboard, Riku is an angry, young warrior intent on saving humanity from the warring Exceed, the sixteen sentient species, fighting to establish the "One True God" amongst the Old Deus. In a lawless land, humanity's lack of magic and weak bodies have made them easy targets for the other Exceed, leaving the humans on the brink of extinction. One day, however, hope returns to humanity when Riku finds a powerful female Ex-machina, whom he names Schwi, in an abandoned elf city. Exiled from her Cluster because of her research into human emotions, Schwi is convinced that humanity has only survived due to the power of these feelings and is determined to understand the human heart. Forming an unlikely partnership in the midst of the overwhelming chaos, Riku and Schwi must now find the answers to their individual shortcomings in each other, and discover for themselves what it truly means to be human as they fight for their lives together against all odds. Each with a powerful new ally in tow, it is now up to them to prevent the extinction of the human race and establish peace throughout Disboard!

Foolhardy police officer Brian Nightraider is dismissed from the force for a history of reckless behavior that ultimately resulted in his partner's death. While wallowing in self-pity, the disgraced officer receives a curious invitation from the United Nations Immigration Bureau Special Investigation Unit. He has been recruited to join the Marginal Service, a secret underground branch of the UN tasked with handling Borderlanders. Indistinguishable from humans, Borderlanders are aliens that peacefully coexist in society. But now, a Borderlander terrorist organization has emerged, manufacturing and distributing a potent drug called Confu. With the Borderlanders' ability to regenerate and blend in as humans, uncovering the drug-trafficking ring will be no easy undertaking. However, the ra group at the Marginal Service are not one to back down from a challenge—even as their work exposes some unexpected figures as Borderlanders.

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]
