Description
Seijirō Kikuoka serves in Japan's Ministry of Internal Affairs and Communications within the Virtual Division, monitoring virtual reality incidents. This role masks his true position as a Japan Ground Self-Defense Force Lieutenant Colonel. He transferred voluntarily to spearhead the classified military endeavor, Project Alicization.
Kikuoka participated as an original Sword Art Online beta tester but avoided the launch, foreseeing the technology's potential beyond gaming or military simulations. This insight birthed Project Alicization, aiming to develop bottom-up artificial intelligence by replicating and accelerating human fluctlights within the simulated Underworld. Newborn infants provided templates for the initial artificial fluctlights.
He systematically cultivated ties with Kazuto Kirigaya, leveraging the boy's obligation after revealing Asuna Yuuki's hospital location. Kikuoka later enlisted Kazuto to investigate the Death Gun incident in Gun Gale Online, offering financial reward. During this Phantom Bullet Arc, he operated under his ALfheim Online avatar, Chrysheight. Pressured by Asuna in ALO, he admitted Kazuto's involvement and later apologized to Kazuto and Shino Asada for endangering them.
Project Alicization dominated his agenda. He oversaw its operations aboard the Ocean Turtle marine base, utilizing Soul Translator technology to interface with fluctlights in the accelerated-time Underworld. To circumvent artificial fluctlights' rigid adherence to the Taboo Index—which obstructed military-useful disobedience—Kikuoka's team induced a lethal plague, causing mass casualties in a failed conflict experiment.
He recruited Kazuto for purported STL machine testing, secretly studying Underworld rule violations. After Kazuto suffered brain damage from Johnny Black's assault, Kikuoka authorized his covert abduction. Connecting Kazuto to the STL was framed as life-saving fluctlight repair, simultaneously advancing Project Alicization by reintegrating him into the Underworld.
Confronted by Asuna on the Ocean Turtle, Kikuoka defended his actions, prioritizing a single JSDF soldier's life over 100,000 artificial fluctlights he deemed wartime tools. This utilitarian stance clashed with Asuna and others who acknowledged entities like Yui as sentient. When Glowgen Defense Systems assaulted the base, Kikuoka engaged combatants, shooting Brigg and aiding Kayaba Akihiko—inhabiting a robot—by eliminating bomb-defuser Hans. To shield Kayaba's fluctlight carrier, he faked his death, later accepted by the government to preserve his cover. During the attack, he prioritized Kazuto's extraction over military goals.
After witnessing the War of Underworld and the inhabitants' resilience, Kikuoka abandoned deploying artificial fluctlights as expendable assets. He vowed to protect the Underworld, hoping future descendants of Integrity Knights or Dark Territory warriors might voluntarily enlist, fulfilling inherent protective instincts.
Kikuoka consistently operates covertly, manipulating civilians—including minors—and crossing ethical lines through non-consensual fluctlight copying, the Underworld plague, and Kazuto's abduction. Though driven by aims to reduce wartime human casualties and achieve Japanese military self-sufficiency—fueled partly by resentment over perceived US exploitation of Japanese R&D and his orphan status after parents died in a potential military-error plane crash—his methods spawn moral complexity. High intelligence underscores his character, often concealed behind an unassuming or deliberately obtuse demeanor.
