Minami Kaburagi, known as "Minami-san" or nicknamed the "mad scientist," is the medical officer and health committee member aboard the destroyer *Harekaze*. Born September 4 in Omaezaki Port, Shizuoka Prefecture, her exceptional intellect allowed her to skip grades, enter Ocean Medical University as a child, complete her undergraduate studies in two years, graduate school in three years, and earn a doctorate. At 12 years old, she is the *Harekaze*'s youngest crew member. Holding a US medical license and ship health manager qualification, she joined Yokosuka Girls Maritime High School as a school nurse to complete mandatory ocean training credits, leading to her assignment on the *Harekaze*. Minami stands 143 cm tall with black hair typically styled in braids secured by yellow bands and light green eyes. She wears the standard crew uniform featuring a distinctive red-lined skirt, often covered by her trademark white lab coat. Her preferred color is white. Due to difficulties walking on a rocking ship, she relies on a personal mobility device. Reserved and thoughtful, Minami frequently employs Chinese idioms, proverbs, and poetic phrases. This habit, combined with eccentric behavior and intense scientific focus, earned her the "mad scientist" moniker. Despite a stoic exterior, she demonstrates a caring nature, advising crewmates like Captain Akeno Misaki. Initially struggling socially due to her age and intellect, she gradually opened up aboard the *Harekaze*, revealing a softer side. Her pragmatic outlook is reflected in her favorite saying: "Failure is the mother of success." She excels in all medical and scientific disciplines, capable of complex diagnoses, vaccine development, and advanced research. During the RATt virus incident, she identified the rodent-carried virus, created an antibody, and courageously tested it on herself. Her technical skills extend to hacking, attempted to access databases aiding petition efforts. She also exhibits ingenuity in non-medical scenarios; during a critical mission against sea pirates, her mobility device was modified into a remote-controlled bomb to disable an enemy fortress’s power room. Her relationships evolved significantly aboard the *Harekaze*. Initially viewing the ship merely as a means to obtain credits, she grew close to the crew through shared challenges. She expressed guilt over not fully participating in the Equator Festival, later suggesting a group song to strengthen camaraderie. Her role as ship’s doctor deepened her commitment to protecting everyone aboard. Key plot contributions include solving the RATt virus outbreak by isolating the carrier rodent, developing a cure, and leading inoculation efforts during rescue missions. In the film adaptation, she devised the strategy to combine her mobility device with a torpedo, destroying an enemy stronghold. Daily quirks like adding salt to cocoa, avoiding spicy foods like mapo tofu, enjoying sewing, and preferring comfort foods like meat-and-potato stew further define her character.
