The End of the World (世界の終焉) is the fourteenth episode of the Sword Art Online and the last episode of the Aincrad Arc. It aired on October 6, 2012.

Plot
Kirito and the others continue fighting, until Heathcliff notices that the boss' life is about to extinguish, so he tells everyone to attack, and after a fierce battle, they finally defeat The Skull Reaper.

Everyone is exhausted from the battle, Kirito informs Klein that 14 players died. The players begins to have doubt about completing the remaining 25 floors. That's when Kirito notices that Heathcliff is standing without any sign of fatigue from the battle, he recalls their duel, and suddenly attacks Heathcliff, but the sword is blocked and an Immortal Object sign appear like when Yui was attacked. Everyone is shocked and confused. Kirito explains that the game ensures that Healthcliff's HP will never fall into yellow zone, and since the game started Kirito has wondered where was "he" was watching the players and adjusting the world from. Realizing that there's nothing as boring as watching someone else play RPG, Kirito concludes that Heathcliff is in fact, Kayaba Akihiko.

Heathcliff admits that he is Kayaba, causing one of the Knight of the Blood to attack him in frustration, but the player is stopped when Kayaba paralyzes him and everyone else aside from Kirito. Kirito asks if he is going to kill everyone in order to cover up the fact that Heathcliff is Kayaba. Kayaba answers that it wouldn't be fair, and instead will be the last boss to wait for the players on the top floor of Aincrad in the Ruby Palace.

As a reward for revealing Heathcliff's true identity, he offers Kirito a chance to fight him on a one-to-one battle while deactivating his immortal status. If Kirito can defeat Kayaba, all of the players will be able to log out. Asuna pleads with Kirito to not accept the challenge and to fall back, but Kirito has flashbacks of all of those who have died and not wanting any more deaths, accepts the wager. Kirito apologies to Asuna that he will not run away and reassures her that he will win and end the game. Agil and Klein beg Kirito to not battle. Kirito thanks Agil for helping the swordman from the middle levels to level up, and apologies to Klein for leaving him on the first day. Klein retaliates that he will not forgive Kirito until he buys him a meal in the real world. Before the start of the duel, Kirito asks that if he does die, he wants Kayaba to make sure that Asuna can't kill herself for a while. Kayaba smiles and accepts the request. Asuna cries out for Kirito.

At the start of the duel, both fight at extreme speed. Knowing that Kayaba designed the Dual Blades skill, and will be able to block the pre-programmed combos, Kirito tries to use his own skills without the help of any Sword Skills. Kirito starts to corner Kayaba, but for an instant he loses focus and activates Eclipse, a high level Dual Blades skill, to which Kayaba easily blocks each and every strike. Dark Repulser breaks on Heathcliff's shield and when he's about to deliver the finishing blow, Asuna jumps between the two, blocking the attack but facing her demise. Kayaba is surprised that Asuna was able to neutralize the paralysis on her own.

In disbelief of losing Asuna, Kirito swings his sword with little effort and Kayaba easily sends his Elucidator flying to stab Kirito, but in the moment his life drops to zero he stabs Kayaba with Asuna's Lambent Light, killing him as well. Kirito asks if "it was good enough" before he and Kayaba shatter into thousand of pieces. A voice of the system announces, "As of 14:55, November 7, the game has been cleared."

Kirito open his eyes and finds himself in the sky outside of Aincrad. Kirito is shocked to see Asuna, and tells her that he is sorry for dying before they hug and share a kiss. While watching the destruction of Aincrad. Kayaba appears and tells them that in 10 minutes or so Aincrad will completely vanish, that the remaining 6147 players were successfully logged out and those who have died are in fact gone forever. Kayaba cannot remember why he created Aincrad but recalls his desire to create a castle, a world that surpassed all laws and restrictions for a long time. He congratulates Kirito and Asuna for clearing the game and disappears.

Kirito and Asuna spend their last moments together, telling each other their real names as they see the last of Aincrad disappear. Kirito being the 16 year old Kirigaya Kazuto and Asuna the one year older Yuuki Asuna. Kirito cries and is apologizes that he was unable to send Asuna back to the other world. Asuna comforts him that it's okay and tells him that meeting and living with him was the happiest moment in her life and that she loves him. Kirito and Asuna hug each other, waiting for the final moment. Both disappear along with Aincrad.

Kirito wakes up and finds himself in the hospital bedroom, while trying to make sense of where he is, he remembers Asuna, bringing tears and life back into his eyes. He takes off the NerveGear and grabs the IV drip stand for support and slowly walks out of his room to find Asuna while calling her name.
