Sword Art Online II Episode 17

Excaliber (エクスキャリバー) is the seventeenth episode of the Sword Art Online II anime adaptation, as well as the third and final episode of Calibur. It aired on November 1, 2014.

Plot
The battle against Thrym began with Thrym's attack. Surviving the initial attacks, the fairies and Freyja managed to bring down Thrym's HP to two bars. However, after they survived a breath attack, Freyja approached Kirito and Leafa and requested them to find her family treasure, a golden hammer, hidden within the room, as they would not be able to defeat Thrym otherwise. Under Leafa's advice, Kirito used «Lightning Fall» to find the hammer hidden in the piles of treasure. Unexpectedly, once the hammer was returned to Freyja, she transformed into a giant man, the god of thunder, Thor. With Thrym's attention occupied with Thor, the fairies rushed to help Thor with their own attacks. Once Thrym's HP was nearly depleted, Thor finished Thrym off with his hammer. Before Thor took his leave, he rewarded Klein with a miniature replica of his hammer. At that point, the fairies found out that the quest had not yet been completed, as Excaliber had not been retrieved yet, and Yui informed them that new stairs had appeared behind the throne. At the room where Excaliber was held, Kirito successfully managed to pull out the sword from its plinth. This caused the roots of the World Tree to grow and Thrymheim to break. As the fairies were falling, Tonkii arrived to rescue them, but, as Kirito could not store Excaliber into his inventory and it was too heavy for him to jump on Tonkii with, he had to leave the sword behind. But unexpectedly, Sinon used an archer spell, called «Retrieve Arrow», to retrieve the lost sword which she then gave to Kirito, after teasing him to always remember her when he used it. The fairies were then approached by Urðr and her sisters who rewarded the fairies for their help. Back in the real world, the group met up at the Dicey Cafe where they celebrated the end of the year and the successful completion of the quest.
