Sword Art Online

Kazuto visits Andrew, the real-life persona of Agil, who explains that the screenshot originated from "ALfheim Online" (ALO), a virtual reality game where players take the role of fairies capable of flight. He explains that the avatar resembling Asuna was spotted somewhere on the World Tree. Discovering that RECT Progress Inc. created the game, Kazuto is convinced that when Asuna logged out of SAO, she was somehow trapped in ALO. Wasting no time, Kazuto logs in to ALO as "Kirito" and selects the shadow fairy Spriggan as his avatar. He discovers that he still has his SAO game data, including skill levels and the SAO in-game item containing the data of Yui, which he activates to bring Yui into ALO as a Navigation Pixie. Yui deduces that the game was made using a copy of SAO's servers, explaining why Kirito's statistics from SAO had been carried over to ALO. After Yui teaches Kirito how to fly using a controller, he assists a wind fairy Sylph player named Leafa in defeating three fire fairy Salamanders, led by lance squad captain Kagemune.
