Jin Shirato is a member of Strega, a group of artificial Persona users opposing the Specialized Extracurricular Execution Squad (SEES). He possesses short dark blue hair, often slicked back on one side, and wears orange-tinted glasses. His attire features a green jacket with detached sleeves secured by black straps, navy blue pants, and black shoes. He consistently carries a silver briefcase, suggesting an age older than SEES members, likely 18 or 19, based on his reference to Mitsuru Kirijo as "little lady." Serving as Strega's tactical adviser and primary information gatherer, Jin operates the "Revenge Request" website used for orchestrating assassinations. In combat, he deals fire-based damage using hand grenades and small bombs. His Persona, Moros of the Hermit Arcana, reflects his isolation and reliance on technology, employing fire, darkness, and ailment-inducing skills. Jin survived Kirijo Group experiments where street children underwent Persona-awakening procedures. From an initial group of 100 subjects, only he, Takaya Sakaki, and Chidori Yoshino endured the lethal suppressant drugs. This trauma forged Jin’s fanatical loyalty to Takaya, whom he credits for freeing him from psychological torment. Despite his tactical rationality, Jin harbors deep-seated hostility toward SEES, viewing them as hypocrites who take their powers for granted. He frequently restrains Takaya’s impulsiveness but remains unaware of his own arrogance. In *Persona 3 the Movie: #2 Midsummer Knight's Dream*, Jin appears alongside Takaya during a summer festival arc. They ambush SEES before their confrontation with the combined Shadow Arcana of Chariot and Justice, using poison gas to weaken the team. Jin participates in trapping SEES and questions their goal to end the Dark Hour, reinforcing Strega’s opposition to eliminating the phenomenon they depend on for survival. Across broader media, Jin’s narrative includes pivotal revelations: he discloses Strega’s connection to the Kirijo Group, their role in Nyx’s arrival, and Shuji Ikutsuki’s betrayal to SEES. His final act occurs in Tartarus, where he sacrifices himself via grenade detonation to hold off Shadows after being abandoned by Takaya, emphasizing his unresolved dependence and failure to attain true freedom. In the spin-off *Persona Record Series*, Jin attacks a group seeking Izanami’s Tomb to save Aiko. After incapacitating Tae Takemi outside the tomb, he battles others inside before being subdued. His defeat involves intervention by Yomotsu-Shikome (the tomb’s guardian) and a finishing blow from Sana Futaba in Rumor form. His dissolution grants a "blessing" to Takaya and Chidori, extending his thematic tie to sacrificial loyalty beyond his original storyline.
