Hina holds the rank of Marine Rear Admiral, promoted after the Summit War of Marineford. She commands the Black Cage Corps, a unit patrolling waters near the Arabasta Kingdom with subordinates Jango and Fullbody. Trained at the Marine Academy alongside Vice Admiral Smoker, she consistently shielded his rebellious conduct from dismissal, preserving their enduring friendship. She addresses him as "Smoker-kun," while he uses her given name alone. Her Ori Ori no Mi Devil Fruit, a Paramecia-type power, generates iron restraints projected from her body as black bars or rings. This ability captures adversaries, constructs cages, and enables naval blockades, earning her the epithet "Black Cage." In the Arabasta Arc, she coordinated with Smoker to investigate Baroque Works, deploying a 30-ship blockade. The Straw Hat Pirates and Mr. 2 Bon Kurei escaped her forces, though she later subdued Bon Kurei’s crew solo using her powers. During the Marineford Arc, Hina joined the siege against Whitebeard Pirates, attempting to capture Monkey D. Luffy before he evaded her restraints. She acknowledged the defeat stoically. Post-timeskip, she escorted the Nefertari family to Mary Geoise in the Levely Arc and discussed the Rocks Pirates with Monkey D. Garp at Red Port. In the Egghead Arc, she informed Fleet Admiral Sengoku of Garp’s mission to rescue Koby from Hachinosu. In *One Piece: Stampede*, Hina deployed to Delta Island during the Pirates Festival. She encountered an undercover Smoker and expressed surprise at his attire. When Marines initiated a Buster Call to destroy the island, Smoker ordered her evacuation. She reluctantly restrained Tashigi, Koby, and Helmeppo with her powers to extract them from combat. Hina maintains professional composure and emotional restraint, rarely showing overt reactions. She speaks in third person (e.g., "Hina failed") and tolerates eccentric subordinates like Jango and Fullbody for their combat utility. Her appearance features waist-length pink hair, dark brown eyes, and dark red lipstick. She dons Marine uniforms with light-blue epaulette variants, purple sunglasses, and in combat, a deep-necked purple blouse with gold motifs and high-heeled boots.
