Ep. 24: Asuna bids farewell to Yuuki, who shares her final sword skill before passing away peacefully.

Months after speaking with her mother, Asuna learns from Kurahashi that Yuuki is dying. Holding Yuuki’s hand, Asuna realizes her friend wishes to return to the virtual world, and Kurahashi permits her to FullDive. At the island where they first met, Yuuki creates a scroll containing her Original Sword Skill for Asuna’s protection. The Sleeping Knights, along with Kirito, Klein, Leafa, Lisbeth, Silica, Sinon, Yui, and many fairies, gather to support Yuuki, having been notified by Asuna to ensure she does not die alone. Yuuki explains that she found her reason for living in these fulfilling final moments. Asuna vows to meet her in another world. A week later, at the memorial service, Asuna meets An Shiun, whose condition is improving. Kazuto and Kurahashi discuss applying the Bidirectional Communication Probe for medical FullDive technology, using data Yuuki provided. Kurahashi reveals that Medicuboid designs originated from Akihiko Kayaba, via Professor Rinko Koujiro, who cared for Kayaba during the SAO Incident.
