Description
Kikuoka Seijirou is a Lieutenant Colonel in the Japan Self-Defense Force operating undercover within the Ministry of Internal Affairs and Communications' Virtual Division. He participated in the Sword Art Online victim rescue, providing Kirigaya Kazuto with Yuuki Asuna's hospital location. This act established a relationship where Kikuoka leveraged Kazuto's gratitude to secure his assistance in investigating virtual reality incidents.
Kikuoka was a beta tester for the original Sword Art Online but deliberately skipped the full launch to pursue Project Alicization, recognizing VR's potential beyond gaming. He maintained an ALfheim Online research avatar named "Chrysheight," derived from "Chrysanthemum" and "Height," referencing the kanji in his surname.
In December 2025, Kikuoka recruited Kazuto to investigate the Death Gun incident in Gun Gale Online, offering payment while withholding critical risk information. He only revealed the investigation's full scope after Asuna confronted him in ALfheim Online.
His primary focus was Project Alicization, a classified JSDF initiative to develop "Bottom-Up" artificial intelligence for military use. The project employed the Soul Translator (STL), technology co-developed by Akihiko Kayaba, to replicate human consciousness ("Fluctlight"). Initial adult Fluctlight cloning attempts failed, leading to experiments with newborns to create a "Soul Archetype." These artificial Fluctlights were raised within the rapidly time-accelerated simulated world, Underworld.
Kikuoka oversaw the project's conception and execution, including the cloning process and accelerated society within Underworld. He manipulated Kazuto into STL testing under false pretenses, seeking to understand why Underworld residents exhibited absolute obedience to the Taboo Index. Kazuto's real-world VR experiences were considered essential to trigger rule-breaking behavior in the artificial Fluctlights.
Following Kazuto's poisoning and resulting brain damage, Kikuoka authorized his covert transfer to the Ocean Turtle facility. Kazuto was connected to an STL to facilitate neural recovery within Underworld. When Asuna infiltrated Ocean Turtle, Kikuoka disclosed Project Alicization's true military objective: creating AI capable of violating laws, specifically murder, for unmanned warfare. He justified this by prioritizing a single human soldier's life over thousands of AIs.
After an attack on Ocean Turtle, Kikuoka permitted Asuna to enter Underworld to aid Kazuto's recovery. He later contacted Kazuto again following unauthorized intrusions into Underworld. Kikuoka consistently operated through manipulation and secrecy, exploiting civilians like Kazuto and Asuna while pursuing technological advancements for Japan's military autonomy, regardless of ethical boundaries.
