an avatar that looks remarkably similar to your brotherEh , there is a bit of a disconnect here . According to the text Kirito ' s ALO avatar looks noticeably different than he does IRL , one of the big features being ashcolored skin . So not only do they look different in terms of features , they also look racially different . Not to mention that I ' m sure fairies have more differences in terms of looks from humans than are apparent from anime art styles . chose a username that shares the first two syllables of your brother ' s sir nameFirst things first , because I have problems , the term is surname . More to the point , that ' s a bit of a struggle to connect due to the Japanese . Kirito ' s name is , whereas his username is . Yes they ' re the same syllables , but because there are so many kanji the kana that match those syllables are likely nottoouncommon . It ' s not like English where we have 26 characters to work with , there are approximately 2 , 000 to 3 , 000 characters commonly used in Japan , a few thousand more that get occasional use , and a total of about 13 , 000 characters that can be encoded in various Japanese Industrial Standards for kanji . We ' re talking about her recognizing a name because of syllables that could match up to any number of literally thousands of kanji . Not to mention that numerous kanji can be pronounced in different ways , creating potentially even more names that could match the kana . this guy who looks and sounds like your brother and who you ' re also falling in love withTo be fair , her falling in love with Kirito was partially forced . She literally states that she was using Kirito to forget about Kazuto , so that ' s a bit of a grey area .
