Natsume (なつめ) is a character that is introduced in .hack//GU vol. 3: At Walking Distance. Not much is known about her role in .hack//G.U. aside from her appearance in a magazine article, pictured along with potential party members.
Natsume is very similar in appearance to the Natsume from Project .hack; they both have green hair, wear a blue one-piece outfit, and have permanently shut eyes. However, Natsume's outfit is slightly more revealing, and her hair appears to be slightly longer and combed down compared to the original.
In real life Natsume is stupid.
