Sword Art Online 4: Fairy Dance

Kirito plunges into a suspicious new VRMMORPG called ALfheim Online to rescue Asuna, who never returned from Sword Art Online. ALO offers many features to entertain players in the wake of SAO: ultra-high-end graphics, action-heavy gameplay, a choice of fairy races, and a next-generation flight engine. Playing as a spriggan, Kirito heads for the location of Asuna's prison - the top of the World Tree, the final destination of every player in the game!
