Kibaou was sentence to be punished after he cause the death of Cobert, when he order his group to go challenge the 74th floor boss by themselves. Before the judgement has been given, Kibaou contacted the Army’s leader to meet face to face, and trick Thinker; sending him into a high-level dungeon unarmed without any armor or weapon. Once Yulier heard about Kirito and Asuna, Yulier came to ask for their help. Kirito and Asuna have doubts about her Yulier’s story, as it could be a trap. However after Yui state that Yulier is ‘telling the truth’; Kirito chose to believe in her story as well and they agree to help. Kirito and Asuna hope the Yui would stay behind, however Yui wouldn’t accept it and they are force to take her along as well.

Yulier explains about the recently found dungeon, in which Thinker is, and that there're strong monsters inside. While Asuna takes care of Yui, Kirito enjoys himself killing all the monsters in his way. At the end he shows Asuna the frog meat he got and tells her that he wants her to cook it, but Asuna instead throws it away.

They finally arrive before the safe area in which Thinker is trapped, Yulier runs toward it, but Kirito notices an enemy and Jumps just in time to save her from being taken down by The Fatal Scythe. Yulier runs to the safe zone and they take Yui, while Kirito and Asuna discuss about fighting the strong enemy or fleeing. They decide to fight, but are easily blown away by just one attack, they can't stand up, and The Fatal Scythe is about to finish of Kirito, when suddenly Yui stands between them, her clothes change back to the ones she used when they found her in the forest and summons a huge sword that defeats The Fatal Scythe in one blow.

Back in the safe area, Yui explains that she's a program focused on studying and monitoring the psychological state of the players, but she was unable to do so because she was blocked by the Cardinal System. She only saw hate, rage and desperation in the players, until she saw Asuna and Kirito, so she decided to meet them. She explains that she's going to be deleted by the Cardinal System for not obeying its orders and says her farewell to Kirito and Asuna.

Kirito takes the keyboard in the GM access found in that safe zone and manages to save Yui's program by transforming it into an in-game object and storing the information in his Nerve Gear's local memory. On the way home, Kirito and Asuna talk about recreating Yui after they escape from SAO.
