Sword Art Online 4 - Fairy Dance 2

Asuna still hasn’t woken up from Sword Art Online, so Kirito has gone after her into an MMO called Alfheim Online.
ALO is a new-generation virtual game. It entices players with action-packed combat where reflexes and strategy determine the winner, fairy races soaring through the skies, and flawless graphics that could rival even SAO. In the game, Kirito, as a Spriggan, is heading towards the World Tree—the location of the main quest and also Asuna's prison.
Along the way, he almost fell victim to a group of Salamanders, but thanks to the help of a Sylph girl named Leafa and the navigation pixie Yui, he managed to escape with his life.
But when they finally stand together before the roots of the World Tree, a nasty surprise awaits them.
