Details: The series is currently ongoing, but keep in mind that the most recent issue came out months after the last issue. It’s pretty much on extreme delay/hiatus. More information can be found at https://kodanshacomics.com/series/ajin-demi-human/
Ajin starts out has a horror/survival story, but quickly turns into a psychological thriller. We get to watch a battle of wits between two characters who seemingly can’t die.
Ajin takes place in a fictionalized version of the real world. It’s mostly the same except a few years ago, society discovered that some people cannot die no matter how much harm you inflict upon them. There are only a few of them, but the world awaits the appearance of the next one.
Enter Kei, a Japanese students who discovers he is an Ajin. If he’s captured, what awaits him is a lifetime of dissection, experimentation and torture. So Kei goes on the run.
I want to leave the synopsis there, but it would be a disservice to ignore the latter 70% of the story. About a quarter into the current number of issues, the writer left the series and the artist took over writing duties. This happens sometimes and usually, the results are lackluster. However, the artist somehow wrote a more interesting story than the original writer.
The story changed with the introduction of the character Sato. I won’t go too much into the character, but his personality and insanity add so much to the series. The series becomes this enormous game of cat and mouse between two relative immortals (Ajin still die of old age, just not physical harm) where the two go to great lengths to defeat each other. Sato especially shows just what you can do with immortality if you’re willing to do whatever it takes.
The art is great and the quality is the same throughout. This is obviously because the artist never left.
Overall, this is a great series. The only caveat I would offer is that recently, the series has been almost entirely on hiatus. There are months between the current issue and the prior issue and it is unclear when the next issue will come out. What’s clear is that the series seems to be reaching its end. We just don’t know how many issues it will take to end. Ideally, this series will have a satisfying ending and won’t be dropped by writer/author with no ending.
