In previous Episode, we see that Kirito and Eugeo left the village and started their journey towards the Central city to find Alice and bring her back. Sword Art Online: Alicization episode 05 begins from the end of the first episode where Kirito got poisoned while trying to save Asuna from Johnny Black, the last member of Laughing Coffin from Aincrad. After Kirito is poisoned, he is in Setagaya General Hospital with Asuna and his sister Sugaha. The doctor came and tell them that he is now out of danger. Because Kirito’s heart stopped for a few minutes, his brain and body could have suffered long-lasting damage and he may not regain consciousness ever. By hearing that Asuna and Suguha is crying.
Then Came Mr. Kikuoka Seijirou who was looking for Kirito’s parents on June 28, 2026. He convinced Kirito’s parents to transfer his into another high tech hospital. After that, they transfer him to the hospital by an ambulance on June 29,2026. The next day, when Asuna and Sugaha go for a visit on June 30, 2026, they weren’t able to meet him. They were told that because of the secret machinery used in the treatment of Kirito, no visitors are allowed.
After that when Asuna is meeting with Liz, Shino-non, Ayano and Sugaha ( Leefa) in the online world, she told them about her experience at the hospital and they all agreed that it sounds really suspicious. They also discovered that, the ambulance that carried Kirito has never gone to that hospital. Then they talks about Kikuoka and Rath, the company where Kirito used to work. They suspect Rath has something to do with Kirito’s disappearance and thought they should look for him at their headquarters in Roppongi.
Then Asuna shows everyone the heart rate monitor of Kirito and asks her AI daughter YUI to follow the heart rate monitor’s signal. YUI last traces Kirito’s heart rate monitor’s signal back to a Warehouse in Minato Ward and after that, it disappeared. So, they decided to split into two groups. One group will look for Kirito’s trace at Rath’s headquarters in Roppongi. And other group will look for him in the Warehouse situated in Shinagawa Wharf, Minato Ward where Kirito’s signal disappeared. Klein, Asuna and Suguha go to Minato Ward and Liz, Shino-non and Silica gone to Roppongi on the evening of June 30, 2026. Liz and others find that Rath headquarters has tight security. They checked the whole places camera footage by using YUI but found no trace of Kirito. He let Asuna and others know about that.
On the other hand, Asuna and others are using YUI’s analytical ability to find Kirito and discovered that there was a helicopter takeoff yesterday. They couldn’t find anything more substantial at that point. Asuna gets really depressed by thinking that Kirito could be out of the country. Then YUI gives her hope by telling her that when she was trapped in Alfheim, Kirito never lost hope for her.
By hearing YUI encouraging words, Asuna regains her composure and asks Sugaha if Kirito ever told her anything about Rath. Then she remembers, Kirito once told her about the Rath’s machine in Roppongi is based on Medicuboid which is developed by Kayaba Akihiko. Asuna realized Medicuboid is must be a Soul Translator ( STL ) device. Then Asuna also remembers about a Rinko Kojiro who was mentioned by Kirito once. Rinko was the one looking after Heathcliff’s ( Kayaba Akihiko) body when he was full diving in the fantasy world of SAO. She was doing full dive research on the same lab as Kayaba Akihiko. But she is now researching on California University. Then Asuna thought, she may know about Rath and STL.
After that, We see Rinko sitting in front of a computer in California and thinking about Akihiko and his dream about Aincrad. She was contacted by Rath for researching with them but she declined. Then she sees a mail from Asuna about Kirito and Rath. So she decided to help.
Almost a month later, we see Rinko and a blond hair girl in a helicopter going to a fort middle of ocean called Ocean Turtle. When they land on the ocean fort she was escorted by Lieutenant Nakanishi. Nakanishi asked about the blond girl to Rinko and she replied by saying she is her assistant Mayumi Reynolds. Then they are escorted inside and checked by a computer for their identity. After confirming their iden, they enter the control room where Kikuoka is waiting for them in Kimono. Rinko sees Kikuoka and asks, why he is in a Kimono. He replied by saying that he is here for almost one month, so he decided to be a little comfortable. While talking Rinko notices her old colleague Hage from Shigemura Lab. After talking for a while, Mayumi Reynolds reveals herself as Asuna and ask Kikuoka where Kirito is ……
