Saigiku Jōno, a key operative within the elite military force the Hunting Dogs, maintains an air of unflappable composure paired with ruthless efficiency in interrogation. His striking appearance—sporting white hair streaked with crimson at the tips and a bell-chimed earring on his right ear—belies the danger beneath his perpetually closed eyes. Blind since birth, his absence of sight is countered by hyperacute hearing, smell, and touch, enabling him to dissect lies through fluctuations in heartbeat, shifts in breath, or fleeting emotional tells. These traits render him impervious to deception, making him a nightmare for those hiding secrets. Before his military tenure, Jōno navigated the underworld as a high-ranking criminal executive. Six years pre-series, Ōchi Fukuchi recruited him for the Hunting Dogs, drawn to his auditory precision and investigative instincts. This invitation doubled as a covert test for entry into the Decay of the Angel, though Jōno ultimately spurned Fukuchi’s offer, declaring allegiance to civilian safety over shadowy agendas. Beneath his polished exterior simmers a volatility quick to ignite. He despises disruptions, hypocrisy, and emotional unpredictability, frequently clashing with peers like the eccentric Tetchō Suehiro through venomous sarcasm or thinly veiled threats. Professionally, he walks a razor’s edge: a self-proclaimed "public evil" who wields legal authority to indulge a sadistic streak, deriving twisted satisfaction from breaking suspects while cloaking his cruelty in duty. His ability, *Priceless Tears*, manifests as the power to disintegrate his body into indestructible particles, evading physical harm and slipping through confined spaces. Fire remains his sole vulnerability, capable of incinerating his dispersed form and halting regeneration. This skill synergizes with his sensory mastery, trapping targets between his intangible assaults and psychological warfare during interrogations. Notable exploits include outmaneuvering Osamu Dazai during a high-stakes horse race by exploiting physiological tells, impaling Tetchō to command an investigation, and confronting Fukuchi’s betrayal. Though merciless, he upholds the Hunting Dogs’ mandate with fanatical loyalty, rejecting Decay of the Angel to prioritize civilian lives over personal power. A former criminal turned self-styled "strongest Hunting Dog," Jōno embodies contradictions—a man of justice steeped in brutality, a protector who relishes destruction, and a polite facade masking calculating pragmatism. His every action dances between duty and darkness, leaving allies and enemies alike uncertain where the soldier ends and the sadist begins.
