I bought this Manga about a year ago now, and decided to write a review for it.

The .hack//LOTB(as it is more commonly known) is in three volumes. The plot differs a lot from the anime.

Spoiler:
	In the manga, Shugo finds a young girl, who has a relation to Aura, but she is not seen in the anime. This girl is an AI and is seen giving Hotaru's grunty an Afro. She also calls Rena, 'Charcoal'.

Spoiler:
	Another difference in the plot, is that Miri's mother used to play The World, and gave her daughter her character. When on the run from system admin, an old friend of her mother's appears and helps them escape.

Spoiler:
	After Shugo fights with the system admin, and breaks her spear, he talks to her and she lets him escape. This is not seen in the anime.

The drawings and story are both very good quality, and it is a shame it was only 3 volumes.
Overall, It is a good read, and I recommend reading it if you ever get a chance.
