Three Sizes (BWH): 82-60-83 Asuna is a friend of Kirito and is a sub-leader of the guild Knights of the Blood (KoB), a medium-sized guild of about thirty players, also called the strongest guild in Aincrad. Being one of the few girls that are in SAO, and even more so that she's extremely pretty, she receives many invitations and proposals. She is a skilled player earning the title "Flash" for her extraordinary sword skill that is lightning fast. Her game alias is the same as her real world name.

Yuki Nagato is a quiet high school freshman that is the only member of the SOS Brigade that was not "voluntarily arrested," or coerced into joining, by Haruhi Suzumiya. When Haruhi claimed the empty Literature Club as the SOS Brigade's clubroom, Yuki was found reading there. Haruhi claimed the clubroom and Yuki as part of the Brigade, both of which she didn't mind. She lives alone in the same apartment complex as Ryoko Asakura. She wears glasses and her school uniform at all times, only discarding the former after Kyon babbled that she was cuter without them and that he wasn't a "glasses man," and the latter when the SOS Brigade went on vacation.
