Just for the record, Pai's name is actually Pi. They didn't get it wrong in the US translation; it was actually meant to refer to the number Pi.

Taken from the .hack wiki:

# Pi's name comes from the number π, which she believes represents herself: an indivisible and unbreakable woman.
# Pi's name was originally written as "Pai" in Japanese sources. However, this turned out to be a mistake.

i think it might have been written down as Pai for the pronunciation of her name possibly. i could be wrong though and assuming to much though.

hmmm, pie

shit, man... do you actually get all these chicks as allies in the G.U. games??? (PS... Pi is actually Ender from the anime for those who've never watched it)

me again!!! hey, you think you can make similar pictures for kite & tsukasa's groups, please?

I didn't make this image... The fact of the matter is nobody that posts here should be posting their own art.

It's art from the GU games, they let you have your own wallpaper when you're not logged in.
