This article is open for adoption.
Aki Natsuki (安岐 ナツキ,Aki Natsuki?) is a nurse who works for the Japan Ground Self-Defense Force (JGSDF) and was assigned by Kikuoka Seijirou to oversee Kirigaya Kazuto's medical condition at «Chiyoda Hospital» when he was hospitalized as well as during his rehabilitation. She is later assigned to watch over Kazuto during the «Death Gun» incident and after Kazuto is injected with succinylcholine.
Aki Natsuki has a tall, slender body and is usually dressed in a light pink or white uniform. According to Kazuto's description, Nurse Aki is an extremely pretty woman with braided hair and glasses. He also mentioned that Natsuki had the clean and beautiful smile of a white-robed angel and that she can become quite scary when she likes to.
Aki Natsuki graduated from the «Tokyo Self-Defense Senior Nurse Academy». As the Nursing Academy is affiliated with the Self Defense Force, those who enroll in the Academy are treated as recruits entering the army, which is why Natsuki not only became a nurse, but also received the rank of Sergeant First Class (Japan Ground Self-Defense Force), and should have been working in the Self-Defense Force's Hospital.
Not much is known about Nurse Aki during the great incident when Kayaba Akihiko trapped 10,000 players, other than that she oversaw Kazuto's treatment during the Sword Art Online incident and during his rehabilitation.
Nurse Aki was employed again during the «Death Gun» incident to oversee Kazuto's care. She also tried to console Kazuto and help him deal with the remorse of taking the lives of three Laughing Coffin members.
It was revealed that Nurse Aki was employed under the Self-Defense Force and was once again taking care of Kazuto while he was in a coma. It was also revealed that she was assigned to «Chiyoda Hospital» to take care of Kazuto by Kikuoka Seijirou, due to him wanting to approach the boy. Nurse Aki also comforted Yuuki Asuna that Kazuto will come back.
