Subaru Nanyō is a former gymnast whose athletic career ended due to injury, forcing her retirement and shattering her original dream. Persuaded by Azumi, she transitioned to pole dancing as a new artistic pursuit. She stands as the tallest member of her performance group, maintaining an athletic build reflecting her gymnastics past. Her features include pale skin, black eyes with a subtle red hue, and short black hair accented by a distinctive red streak. Her bangs are cut longer on one side, covering her right eye. She showcases a unique performance style in dedicated routines, like one choreographed to "Remain." Her stage attire incorporates elements such as headphones, belts, jackets, and midriff-baring designs. Her name, "Nanyō" (南曜), combines "south" (南) and "shine" or "day of the week" (曜), while "Subaru" (スバル) references the Pleiades star cluster. The circumstances of her recruitment into pole dancing are noted for their lighthearted, comedic tone.
