Sword Art Online - S03

The Soul Translator is a device that connects to a person’s Fluctlight-a digital version of the human soul-and works differently from traditional brain signal interfaces. The secretive organization Rath is refining the technology with help from Kazuto Kirigaya, who works part-time testing the system in a virtual world created by the Soul Translator. Due to a confidentiality agreement, all memories formed inside this world are erased upon returning to reality. Yet Kazuto faintly remembers one name-Alice-and it leaves him unsettled. One night, while walking Asuna Yuuki home, Kazuto encounters a dangerous enemy from his past. He’s badly injured in the fight and blacks out. When he wakes, he finds himself trapped in the Underworld with no clear way out. Now, he must find a path back to the real world.
