The listing, .hack//AI Buster light novel has ended.
This is not a manga but a light novel with some pictures in it from the .hack series. Reads left to right, the cover is a bit worn but over all good condition.
Summary
In an epic prequel to .hack the avatar Albireo is a solo adventurer in the World- the most advanced online fantasy game ever created. When he comes across Lycoris, a strange little girl in a dungeon, Albireo wonders if she's simply nothing more than a bug in the system.
As the two journey further into The World, Albireo watches Lycoris turn all of the rules of The Wold upside down. Slowly, he comes to realize that she may hold a very deadly secret- a secrete that could unhinge everything in the cyber-world and beyond.
