Nanase is the main character of .Hack//Alcor and she plays as a PC similar to that of Alkaid in .Hack//G.U.+ as well as in .Hack//Alcor. She is part of the Canard Guild but was once part of the guild Kestral which causes problems for her early in the series. It is quite obvious that Nanase has a crush on Silabus also in the Canard Guild but is quite jealous of Alkaid who seems to be attracting Silabus attention.
