When he is first introduced in the series, he is seen blaming the beta testers for the deaths of the beginner players and demands that all the beta-testers apologize for the deaths that they "caused" and give out all the items they had acquired to other players. However, Kibaou is later silenced by Agil, who defends the beta testers by revealing that the free guidebook, which can be obtained for free at any store and is written by said beta testers.

Kibaou is one of the players who were part of the Boss raid of the first Floor and also the leader of group E, in charge of handling the sentinels, during the battle. After the Boss fight, he blames Kirito for the death of Diabel, as he saw how Kirito never healed him. Due to this, the beta-tester hatred resurfaces, which leads to Kirito self-proclaiming himself as a Beater in order to stop the beta tester discrimination for good by drawing all the hatred onto himself.

The Day Before
Kibaou was mentioned to have been regarded as the leader of the clearing group. Fed with the false information regarding the 25th floor boss, the clearing group suffered massive casualties.

Kibaou retired from the front lines after the debacle. «Knights of the Blood» took charge of the clearing group afterwards.

As a warrior and leader of a faction within «The Army» promoting independent action and increasing individual strength, he stages a coup on the leader of the Army, Thinker, while he was about to be expelled due to his mistakes, and seizes control of the Army. Kibaou's faction was well known to be very corrupt as they abused their authority even on children by extorting taxes and other stuff. He also ordered the army squad led by Corbatz to take on the 74th floor's boss after being mocked for being on the sidelines too much. After their slaughter, he was placed under a lot of heat. It was at this point he staged the coup stranding Thinker in a very high level dungeon and used his influence to stop the rest of «The Army» from interfering. At the end, after Thinker is rescued by Kirito and Asuna from the dungeon, he is finally overthrown.

Kibaou was logged out after Kirito killed Heathcliff, prematurely clearing the game.
