Episode Title:
Excaliber.
Episode Description:
The group engages in battle against Thrym, overwhelming him with their attacks, but he soon retaliates. Among the pile of gold, Kirito finds a golden hammer and tosses it to Freyja, who suddenly transforms into Thor, the Norse god of thunder. With the group's help, Thor defeats Thrym once and for all, rewarding Klein with the golden hammer Mjölnir. A staircase opens up and leads to the last floor, where Kirito pulls the sword out of the ice with much effort, causing the floor to break off and drop down a chasm. As Tonky arrives to save them, Kirito is forced to throw Excaliber into the chasm due to its heavy item weight, but Sinon uses her bow and arrow to retrieve it. As a result, Jötunheimr is rejuvenated and filled with fresh water and greenery. Urðr and her sisters Verðandi and Skuld appear and thank them for saving Jötunheimr, in which Urðr rewards Kirito with Excaliber. In the real world, Kazuto, Suguha and Shino test out an audiovisual bidirectional communication probe for a mechatronics project to allow Yui to interact with the real world. The group later has lunch to celebrate the conclusion of the quest.
