The Holy Grail is a powerful, ancient relic capable of granting any wish the beholder desires. In order to obtain this power, various magi known as "masters" summon legendary Heroic Spirits called "servants" to fight for them in a destructive battle royale—the Holy Grail War. Only the last master-servant pair standing may claim the Grail for themselves. Yet, the third war ended inconclusively, as the Grail mysteriously disappeared following the conflict. Many years later, the magi clan Yggdmillennia announces its possession of the Holy Grail, and intends to leave the Mage's Association. In response, the Association sends 50 elite magi to retrieve the Grail; however, all but one are killed by an unknown servant. The lone survivor is used as a messenger to convey Yggdmillennia's declaration of war on the Association. As there are only two parties involved in the conflict, the Holy Grail War takes on an unusual form. Yggdmillennia and the Mage's Association will each deploy seven master-servant pairs, and the side that loses all its combatants first will forfeit the artifact. As the 14 masters summon their servants and assemble on the battlefield, the magical world shivers in anticipation with the rise of the Great Holy Grail War. [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]
