Saigiku Jōno is a white-haired Hunting Dog with distinctive red-tipped ends and a bell earring on his right ear. His eyes remain closed due to blindness, offset by extraordinarily sharp senses of smell, hearing, and touch. These heightened senses detect physiological functions like heartbeats and respiration, along with emotional states, making him immune to sensory illusions. Recruited into the Hunting Dogs six years ago by Ōchi Fukuchi, Jōno was previously a criminal organization executive. Fukuchi recognized his sensory acuity and combat potential, also considering him for the clandestine Decay of Angel group. Jōno typically maintains composure yet harbors a volatile temper, frequently threatening his eccentric comrade Tetchō Suehiro. He expresses clear disdain for interruptions, injustice, and sudden emotional shifts in others. His sadistic nature emerges during interrogations, where he psychologically torments targets to extract information—a stark contrast to Suehiro's sympathetic approach. Jōno openly admits deriving pleasure from suffering, declaring his desire to "hurt people in the name of the law" and "hear the sound of their destruction," acknowledging himself as a "public evil" lauded by society. However, exposure to civilians' gratitude during his service fostered a sense of responsibility. Notably, an elderly woman thanking him for protection influenced his decision to oppose Fukuchi’s genocidal plans, revealing a latent commitment to justice. Jōno’s ability, **Priceless Tears** (千金の涙, *Senkin no Namida*), allows partial or full bodily disintegration to evade attacks and inflict damage. Named after a kabuki play by his real-world namesake, the 19th-century journalist and playwright Jōno Saigiku, the play's themes of betrayal and tragic loss resonate with his narrative. He integrates this ability with his sensory skills for efficient tracking and interrogation. During the Vampire Infection Outbreak arc, Jōno uncovered Fukuchi’s leadership of the Decay of Angels and confronted him alongside Suehiro. This betrayal stemmed from rejecting Fukuchi’s nihilistic worldview; Jōno prioritized civilian protection above loyalty to his commander. His declaration that “one’s lament is nothing to compare to the pleasure of protecting civilians” underscores his evolution from a self-professed sadist to a conflicted enforcer of justice.
