I already reviewed this manga when it was ongoing (you can read my review here) but not that the manga is finished is it good or not?
Story: The manga follows the anime for a lot of chapters but is faster and explains better the rules of Accel World and the relationships of the main characters. We start with Haruyuki, the main character, that is bullied and Kuroyukihime,
the school's most beautiful and refined girl, introduce him to a software called “Brain Burst” and the benefits that the software has. But there aren't only benefits, there are even some side-effects. But that’s not all: Kuroyukihime asks him to beat the game reaching the level 10.
The plot is easy but there’s a lot of rules that are slowly explained and characters that have a lot of secrets. I really like how the rules are explained and the characters develop.
The drawings are especially well made and sometimes I stop to appreciate them.
Sadly the manga stops after 45 chapters and don't have a proper ending so you need to read the novel to know what happens after.
A little note to say is that there are some chapters with Kirito from Sword Art Online. This special arc has a quick plot (a battle Kirito VS Silver Crow) and some explanations about both SAO and Accel World.
My rating: 9/10
