Hokutozai Minami was a prominent news reporter before the global petrification event. She maintained an extensive professional network to gather detailed information for her stories, taking pride in her work and refusing to utilize sex appeal for reporting. She owned a cherished camera, attempting to photograph the petrifying light before being turned to stone herself, leading to the camera's destruction over millennia.
Revived by the Tsukasa Empire due to her reputation and research skills, Minami aligned with Tsukasa Shishio, whom she admired pre-petrification, sharing his philosophy opposing the revival of corrupt adults who might recreate societal inequalities. Tasked with selecting individuals for revival, she identified valuable additions like Yo Uei and Ukyo Saionji based on her knowledge of their capabilities. Following Tsukasa's incapacitation, she joined the Kingdom of Science at Senku Ishigami's request. Her initial reluctance to revive Ryusui Nanami, due to his perceived spoiled, wealthy background, was overruled by Senku. After observing Ryusui's leadership and ambition benefiting the group, she revised her opinion of him.
Her journalistic expertise remained central. She exchanged her last revival fluid for a replica camera crafted by Senku, moved to tears by its restoration of her professional identity. She documented the Kingdom of Science's endeavors, including the Perseus voyage, and organized commemorative group photos. She expressed emotional distress during separations, like the crew's departure for America, and profound relief upon Tsukasa's eventual revival.
Minami demonstrated fluency in English and Japanese, leveraging her linguistic skills to negotiate with Brody for Corn City's establishment. Her research abilities facilitated identifying specialists like Joel Gear to disassemble the petrification device. She maintained acute observational skills, noting distant objects like Senku's firearm during aerial combat. Her personality blended emotional vulnerability—crying during pivotal moments—with tenacity in pursuing stories, probing relationships among allies. She disliked Moz's overprotective behavior toward women but acknowledged his combat prowess.
Physically, Minami possessed moderate height, very long blonde hair, and brown eyes. She typically wore a shoulderless burgundy dress with thigh splits, a tan ribbon below her chest, and no shoes. After petrification scars vanished, she adopted war paint mirroring her former stone markings. Her name translated directionally as "North, East, West, South."
