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.

Ajin is scheduled to be streamed by the multinational provider Netflix worldwide after the current run ends.

REVIEW (for the 2 seasons): An anime with a very interesting proposal and story and a captivating villain.
What gets in the way a little is the 3D animation, which was still emerging as a new animation technique, causing some initial strangeness, but there is fluidity in the movement.
The characters and the story develop well, with development in the characters and deepening in the antagonists. Dealing with more serious matters, with a good Seinen. The action happens in a good measure, in a well-choreographed way and with several heavy scenes.

Greetings, all you cool cats and kits! This is your old pal Kiba Snowpaw, Ice Wolf extraordinaire, manga aficionado since the 80's, movie watcher, serial binger, and gamer - the one who has run with the likes of Sonic and shrugged off fireballs from Bowser. If I could harness the same stamina I've got for devouring anime for anything else, well... we'd be living on the moon by now! Now, let’s dive into the rich, intriguing, and somewhat controversial world of the anime, Ajin: Demi-Human.

You could say that Ajin is the black sheep of the family - it's the cousin who brings a homemade flamethrower ...

It's a shame that such a passable concept was ruined with such violently bad animation. I'm not stuck up enough to think that I could do better, and I understand that talented people probably put a lot of work into making this anime look the way it does, but I think they're all in the wrong business.

It's not even the FPS and speeding it up doesn't make it look any less terrible. The animation doesn't look like anime; it looks like one of those free video animation sites that we all used in high school to make presentations. It looks like an artificial intelligence was ...
