In Sword Art Offline 2 7 when Yuuki learned that Asuna was married in-game and she and Kirito had Yui as their daughter, she started saying how she would want to marry Asuna and make her happy and have many babies with her (not knowing how babies are made). This also seems to spark a rivalry between her and Kirito in Sword Art Offline 2 7.
I remember reading that Yuuki in real life is also female and there is some fanart of an Asuna x Yuuki pairing here, here and here.
Now I know that like any other pairing, fanbase shoujo ai/yuri fans would jump at Yuuki's comments in Sword Art OnlineOffline. However i am wondering if there is any evidence that indicates that Yuuki is bi/homosexual and that her comments in Sword Art Offline are sincere, that she would want to marry Asuna and (with her limited understanding of hwo) have babies with her.
EDIT: by bi/homosexual I am referring to if Yuuki would have deeper feeling for the same sex.
