Teruko Ōkura is vice-captain of the Hunting Dogs, a military unit enforcing order with ruthless efficiency. Her deceptively youthful stature—a petite frame, light wavy hair pulled into a ponytail—clashes with her ferocious reputation as the "blood-briar queen," renowned for wielding a steel whip and a sword. She dons the Hunting Dogs uniform, adjusted to secure her ponytail, and harbors *Gasp of the Soul*, an ability to manipulate age via touch. This power fuels combat tactics, interrogations, and disguises, shifting her form to an adult, elderly woman, or child as missions demand. Intensely volatile and brash, she champions the Hunting Dogs’ creed of violent peacekeeping, declaring herself a "slave to society’s order." Her justice is laced with menace, openly relishing threats to gut adversaries. Obsessive loyalty binds her to Captain Ōchi Fukuchi; subordinates who question him face mockery, while her trivia whims—coveting Fukuchi’s discarded socks, demanding piggyback rides—hint at a capricious, almost childish undertone beneath her brutality. A veteran of the Great War at age twelve, she now operates in her mid-to-late twenties, enduring monthly surgeries to augment her combat prowess, a physical testament to her creed of total sacrifice. *Gasp of the Soul* doubles as psychological warfare: accelerating a victim’s aging to extract confessions, then reversing the decay. Though her role solidifies the Hunting Dogs’ moral grayness, fleeting glimpses of humor—taunting failed subordinates, trivial fixations—puncture her otherwise unrelenting facade.
