Area D was a frustrating experience. The manga starts well, it introduces the concept of powers clearly and at the same time gives a nice dimension to each character that will be relevant to the story. It adds to a powerful art that delivers exciting moments and already captivates the reader. The characters are very charismatic and the author manages to tell the story in a way that makes them seem more human and independent instead of just supporting the protagonist. They have a past that carries desire, guilt and makes them have independent actions that add up to the plot. Seriously, it's funny to see acharacter discover something on his own and then summarize his discovery for others, it makes it feel organic.

The story is also well structured in the way it is told. It's a very simple shounen action, but it also manages to be engaging since one event in the plot leads to another in a consequent way so that you can feel good planning.
In addition, the world still manages to be explored in a cool way for the story. By being limited to one island, the author is smart to give each area personality: a classier women-only zone, a delinquent-style zone, and an animalistic zone, etc. Each of these places being explored and giving a feeling of good use of the world itself.
And as much as the protagonist, Jin, is a simple character, he still manages to act well in the plot with action and ideas that make him have value in the story beyond the beating. He has philosophies, but they are constantly put to the test and that's a good thing!

Unfortunately , the manga still disappoints. Unfortunately, this is most likely the result of a cancellation due to the story suddenly speeding up so that all the events are barely developed and just happen... And this is very remarkable, as the author begins to insert new characters that end up not even being developed simply because there was no time.
At least, the ending closes all the ends. In a rushed and poorly developed way, but at least it doesn't leave open ends.
