Kazuto "Kirito" Kirigaya and his sister Suguha meet up with Asuna Yuuki, Rika "Lisbeth" Shinozaki, and Keiko "Silica" Ayano at the SAO Survivor School a few years after the events of Sword Art Online. After that, Kirito goes to emergency counseling while the girls continue swimming at the pool. It turns out that the "emergency counseling" was a ruse concocted by Seijirou Kikuoka in order to revisit the Sword Art Online event in order to figure out Akihiko Kayaba's motivations. What will the girls do in the pool, and what does Kirito have in store for him and his "counseling"?
