Plot Summary

Asuna looks at Kirito and Klein
Asuna looks at Kirito and Klein

As Asuna and Kirito open the door, their eyes lay upon a terrifying blue creature equipped with a large sword. They run towards the exit and manage to exit the boss room. Kirito mentions that they should have ten people with shield, and Asuna finds it strange that Kirito does have a shield or Lisbeth's forged sword. Then, she opens her inventory to bring out the sandwiches she made. Asuna brings out the spices and sauces that she experimented. Kirito remarks that Asuna could make a lot of money by selling the food, but he changes his mind saying that he will not get a chance to try her food. Out of the portal, Klein emerges with his team all exhausted, and he sees Kirito with a girl since Kirito is usually a solo player. Kirito introduces Asuna and Klein to each other, and both Klein is shocked. Klein tries to hit on Asuna, but Kirito knocks him out. Klein's guild members surround Asuna to get her attention.

From a distance, they see the Aincrad Liberation Army who they mentioned is strengthening their army. Lt. Col Corbatz asks Kirito if they have the map data, and he states that he is dividing the resources for all players. Kirito gives the map data much to Klein and Asuna's protest since Kirito is going to make it public. Lt. Col Corbratz decides to move his army towards the boss room, and Kirito suggests that they should follow them. Kirito and Asuna hear screams, and they find out that the guys cannot use teleport crystals in the room. Kirito starts to have bad memories from his guild that was trapped in a similar room. The lieutenant dies right in front of them, and Asuna freaks out and attacks the boss. Asuna gets hit, and Kirito helps save Asuna. Kirito has difficulty battling the boss, and he thinks about using that item. With the death of Sachi in his mind, he asks Asuna and Klein to hold the boss off for ten seconds.

Equipping the Star Stream Burst sword, Kirito wields two swords, and as he battles the boss, he tells his body to go faster. Kirito manages to defeat the boss with only small amount of health left. He blacks out, and later, he wakes up to see Sachi. However, it's Asuna who is crying, and she hugs Kirito tight. Klein asks Kirito about his new move, and Kirito explains it's a dual blade skill that he doesn't know how to obtain it. He tells Klein that he did not mention his secret skill, and Klein tells Kirito that he is happy to see Kirito jumping in to save the everyone. After Klein and his guild leave, Asuna tells Kirito that she is taking a break from the guild since she is Kirito's partner. Meanwhile, Egil talks how Kirito make the news, and Asuna arrives to take Kirito to a meeting with Commander Heathcliff. Upon hearing Kirito's success in defeating the boss, Heathcliff challenges Kirito to a duel. If Kirito wins, Asuna will have the right to leave the knights guild.
