Hokuto

Hokuto is the name of the PC of Haruka Mizuhara and one of the main characters of .hack//AI Buster. Though really played by an experienced player, she pretends to be a newbie. Her online personality is fairly hyper, and she has the tendency to give her friends odd nicknames. When she's around people who know her true identity she drops the newbie act, and acts like the mature woman she actually is. Hokuto was created so that Haruka could enjoy The World without worrying about running into her boss, who would recognize her original character, W.B. Yeats. Source: Dot Hack Wiki
