3.5
In this last couple volumes, the story seems to be going a different direction; or maybe it was always intended to be that way, but what it started like mostly a sci-fi and mystery story, is now turning more into sorts of a political intrigue thriller much heavier in action, and maybe not as much in feelings anymore.
As such, I'm personally finding the series a little bit less interesting, and the art that looked original at first is also starting to feel a bit tired to me, especially when it comes to character depiction. I'll just say that, for a long while, I thought Akira was actually a girl... duh.
So even though this is still quite a original story, it is not holding as well as it did at the beginning for me.
