Mokutarō Kikuta, a Warrant Officer in the Imperial Japanese Army’s 7th Division, hails from Saitama Prefecture and once shaped recruits as an instructor at the Army Academy. Among his pupils was Saichi Sugimoto, whose innocence mirrored that of Kikuta’s late younger brother—a brother whose death in military service fuels Kikuta’s torment, convinced his own persuasion doomed them both to "vip seats on the train to hell." Towering and broad-shouldered, Kikuta bears a square-jawed face framed by side-parted dark hair and shadowed, downturned eyes. A jagged scar branches across his chest from pectoral to abdomen, a stark contrast to the array of holsters strapped over his torso, each housing a Nagant M1895 revolver for swift combat transitions. His attire is marked by a dark-brown striped scarf, claimed from Toni Anji, a blind convict turned adversary. A veteran of the Russo-Japanese War, Kikuta scavenged firearms from fallen foes as grim souvenirs. His service later entangled him in the 1902 Koito kidnapping, discreetly disposing of Russian assailants’ remains at Fort Goryokaku while monitoring Lieutenant Tsurumi’s dealings. In Noboribetsu, he pursued a straw-booted figure clad in Ainu designs alongside Privates Ariko and Usami, culminating in a sulfurous clash with Anji in Hell Valley. There, Kikuta’s multi-revolver tactics and terrain adaptability turned the tide. Guilt binds him to Ariko, whose father’s demise Kikuta inadvertently caused. Yet he trusts Ariko’s mountain expertise, relying on it during covert operations. Pragmatism drives Kikuta to execute Tsurumi’s orders—espionage, kidnappings—without hesitation, though peers like Usami provoke his ire when dismissing his capabilities. Eager to prove worth, he hunts tattooed convicts for intelligence to regain Tsurumi’s approval. A strategist attuned to environmental cues, Kikuta once tracked foes through echoing ice caves by sound alone. His dry wit surfaces in chiding Ariko for vanishing acts, tempered by grudging praise for the private’s cunning. He savors watermelon but spurns Tsukisamu anpan. Though later chapters of his journey remain unchronicled, Kikuta’s narrative anchors itself in unyielding loyalty to the 7th Division, battlefield ingenuity, and the weight of a past that sharpens both his resolve and his scars.
