第 15 集: 桐人探訪昏迷的亞絲娜，並直面須鄉的收養計畫，同時收到一封神秘郵件。
Two months after the end of the original SAO incident, Kazuto's sister, Suguha, continues to worry about him. Kazuto goes to the hospital to visit Asuna who, along with 300 other players, has yet to wake up after the SAO incident. It is there that he meets an associate of Asuna's father, Shouzou; and Nobuyuki Sugou, who works for him. Much to Kazuto's fury, Sugou tells him that he intends to be adopted into Asuna's family, while she is still in acoma, as a precursor to marriage. Later at home, Kazuto breaks down before Suguha, who tells him not to give up, despite knowing Kazuto is actually her cousin and harboring her own feelings for him. The next morning, Kazuto receives an e-mail from Andrew Gilbert Mills, Agil's real-life persona, with a screenshot from another game of an avatar, a graphical representation, which resembles Asuna.
