Summoned to Egil's shop, Kazuto's gaze is drawn to a screenshot that Egil shows
him - that of a VRMMORPG called Alfheim Online (ALO).
A girl resembling Asuna can be seen in this screenshot. When he finds out that the company that launched ALO is RECTO, where Sugou works, Kazuto is convinced that Asuna is trapped inside the game.
Wasting no time in logging into ALO under the name Kirito, he discovers that for
some reason, his newly-created character has retained all of his SAO data."
