Description
Seijirō Kikuoka first appeared as a representative from the Ministry of Internal Affairs and Communications' Virtual Division, tasked with monitoring virtual worlds. His true role was later exposed as a Lieutenant Colonel in the Japan Ground Self-Defense Force (JSDF). He had been one of the original 1,000 beta testers for Sword Art Online but skipped the full launch to concentrate on developing the classified Project Alicization. This initiative aimed to create artificial fluctlights (bottom-up AI) for military applications like unmanned weapon systems.
Following the Sword Art Online incident, Kikuoka contacted Kazuto Kirigaya (Kirito), offering critical information about Asuna Yuuki's hospitalization in exchange for details on the SAO incident. This initiated a pattern of leveraging Kirito's cooperation for investigations, beginning with the Death Gun case in Gun Gale Online. Kikuoka persuaded Kirito to investigate mysterious deaths linked to GGO, requiring Kirito to convert his ALfheim Online avatar. During this investigation, Asuna confronted Kikuoka in ALfheim Online under his avatar "Chrysheight," compelling him to reveal the mission's true nature.
Kikuoka's involvement deepened significantly during Project Alicization. He oversaw the cloning of newborn infants' souls to generate artificial fluctlights and accelerated the Underworld's societal development through time manipulation. His methods included ethically questionable actions, such as triggering a plague within the Underworld to test the residents' capacity for survival-driven violence. This resulted in numerous deaths but failed its intended purpose. After Kirito suffered brain damage from an attack, Kikuoka orchestrated his abduction to connect him to the Soul Translator (STL), aiming to facilitate Kirito's recovery while advancing Project Alicization's objectives.
During the War of Underworld arc, Kikuoka confronted threats to the Ocean Turtle facility from foreign operatives seeking the fluctlight technology. He engaged in direct combat, including a gunfight where he faked his death to protect a robot controlled by Kayaba Akihiko, ensuring the Underworld's safety. Despite his earlier stance that artificial fluctlights were expendable tools—prioritizing one human life over 100,000 AIs—he later vowed to protect the Underworld and its inhabitants, while still hoping they would voluntarily participate in future military endeavors.
In the movie *Ordinal Scale*, Kikuoka assisted Kirito in uncovering a conspiracy involving memory theft from SAO survivors via the Augma device. After resolving the incident, he recruited the perpetrator, Dr. Shigemura, for Rath, recognizing potential in his AI research.
Kikuoka maintained the ALfheim Online avatar "Chrysheight" for research and communication. His personality exhibited eccentric traits, including discussing obscure topics like Kiviak in casual settings, and he possessed a noted strong preference for sweets. Kirito regarded him with deep distrust, considering him the third person he hated most after Heathcliff and Sugou.
Kikuoka's backstory revealed he was orphaned in the 1980s after his parents died in a plane crash, an incident potentially caused by a misfired military missile. This tragedy influenced his commitment to removing human soldiers from warfare, though his methods often involved manipulation, secrecy, and morally gray decisions concerning civilian minors like Kirito and his friends.
