Throughout history, an elite group of shrine maidens known as "Toji" have saved the world from "Aratama," strange and malevolent beings bent on destroying humanity. In modern times, these warriors have been assigned to a special police squad to exterminate Aratama. The government has also set up five elite schools across the country to provide young girls the necessary sword fighting skills to eradicate these monsters and eventually join their fellow Toji in protecting the world. A student of one of those five schools, Kanami Etou is chosen to represent Minoseki Academy in a sword fighting tournament, where she meets the mysterious Hiyori Juujou. Although Kanami and Hiyori rise to the top of the tournament, their battle takes an unexpected turn, throwing the world of the Toji into chaos. Likely that the Toji are facing betrayal from within, the two are forced to flee the tournament, clashing with former comrades on the way. [Written by MAL Rewrite]

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]

Kei discovers unlikely allies in the form of two former adversaries: high-ranking government official Yuu Tosaki, whose extensive research on Ajin gives him a tactical advantage in the fight against Satou, and Tosaki's Ajin assistant Izumi Shimomura. As his faction continues to gather allies, Kei races against time to put a stop to Satou's crusade before it brings about an end to civilization as he knows it. [Written by MAL Rewrite]
