The second season of Ajin – Demi Human is up on Netflix and my husband and I decided to binge watch the entire thing on our anniversary! Despite that, there are a couple of things that I’m not super happy about that revolve around where the show is headed, so let’s get into some discussion!

Since this is a second season I’m not going to get too into the basics like I normally would with a review. This is going to be staying within the story / character development confines, so if you’d like to read about my opinions on everything else please click here to see my Ajin season 1 review.

Summary – (For those of you who are just now jumping in)

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.



I’m going to start this review off by saying that I’m concerned with the direction they’re taking this story. It is still intriguing, and I’m interested enough to hold out for the third season, but it’s feeling very drawn out in a not so good way.

When discussing this with my husband we both realized that we can’t really recall what all went down this season. We watched it mid January, and while that may seem like a decent stretch of time, we watched the first season in July and both fully recall everything that happened then.


The point I’m trying to make is that Ajin is trying too hard to extend the drama. Certain scenes felt repetitive and the main arc of this season fell flat for me.

There were a couple of really cool moments that I hope they extend upon in the future. The introduction, and re-introduction, of certain characters have the potential to change the flow of the story in a great way.


Despite the plot points falling short, they are important to the overarching narrative. Things that happen between Mr. Satou and Kei’s gang build up to what will hopefully be a climactic ending.

Character Development


This is something that did not disappoint this time around. The last season showed us a bit about Kei’s psyche; that he’s a sociopath that doesn’t understand how to truly react to other people or the world around him. This is what made his relationship with Kai so interesting. They are complete opposites in almost every way, yet they mange to work very well together. Kai makes a come back in this season and we get to see how strong his loyalty to Kei is.


When it comes to Kei and Kou however (these names are killing me with their similarity by the way), they are like oil and water. They don’t mix no matter how hard they try to and it brings an interesting element of constant friction between the two. We were able to see a bit of this at the end of last season when they were ‘enemies’, but with them now attempting to work together the story gets even more complex.

I appreciate the ride we see Kei  go on. He has to make tough decisions about how he wants to progress with life as an Ajin as well as the battle with sociopathic tendencies.


We learn a bit more about Satou too. Nothing really important yet, but they are definitely hinting at things that are going to be important later and that’s something I’m very excited about.

Final Thoughts


All in all I did enjoy Ajin season 2. There are a lot of better ways they could’ve approached the story, especially when it came to Satou, but they got their point across with some cool moments. The characters are wonderful and I still feel very attached to what they’re trying to accomplish. I can’t wait to see where they take the narrative in the future. Here’s to hoping it ends in a fitting way!

Thank you so much for reading! If you have something you’d like to add to the discussion, please feel free to comment! I love talking about stuff like this with others!
