Kibaou

One of the participating players in the first raid party to defeat the first floor boss. He openly spoke out in the first meeting and called out the beta testers hiding in the meeting. He wanted to have them apologize to all the players of SAO for not sharing their knowledge in the game and monopolizing the efficient hunting grounds.

He was mentioned in volume 2 that he was one of the leaders of <The Army> along with Sinker.

His name is in katakana but if read in kanji, it means "Fang King".
