Ajin Demi Human ⁽⁶⁾

Ajin presents the story of a student named Nagai Kei, who discovers he is an "Ajin" when he is fatally wounded in a traffic accident. In the world of Ajin, a small number of humans (termed "Ajin") possess immortality and extreme regenerative abilities that trigger upon death, allowing them to completely recover from any mortal injury in a matter of seconds. Ajin can also create "black ghosts", highly dangerous combat-oriented entities that are only visible to other Ajin. "Black ghosts" are resistant to physical injury, exhibit extraordinary physical strength, and have sharp teeth and claws. Different "black ghosts" have varying degrees of intelligence: most are completely reliant on their Ajin for directions, and others, such as Kei's, are more independent and likely to engage in self-initiated actions.
