Minami Hokutozai is a pre-petrification human who worked as a journalist before the petrification event. In the stone world, she was revived by Tsukasa Shishio, whom she deeply admires. She uses her prior knowledge of famous individuals and her sharp information-gathering skills to help Tsukasa locate strong and capable people to bolster the power of the Tsukasa Empire. After the empire merges with the Kingdom of Science, she continues to serve as an intelligence officer, known for her keen observational abilities and her network of contacts from the old world. Minami typically appears barefoot and wears a leather dress. Her role in the story is primarily as a supporting character who provides crucial intelligence, such as the location of Ryusui Nanami, the heir of the Nanami Conglomerate, whose sailing expertise is essential for Senku’s plans. She does not undergo significant personal development over the course of the series, remaining a steady asset to the kingdom through her information-gathering. Her notable ability is her talent for research and data collection, which she applies to help the group identify key individuals and resources needed for their scientific and exploratory projects.
