Hinano Hoshikita is a 17-year-old introverted and mild-mannered girl who struggles to express herself openly. Despite her reserved nature, she exhibits persistent effort and anchors her group emotionally. Her motivation stems from a profound childhood attachment to her grandmother's planetarium. Upon discovering its imminent closure, she actively searches for solutions to preserve it. A turning point occurs when she coincidentally witnesses Azumi pole dancing beneath a starry sky. Inspired, Hinano adopts pole dancing as a potential means to draw crowds and rescue the planetarium. She enlists her childhood friend Lilia and other acquaintances to join the cause. Together, they create a performance stage inside the planetarium, blending astronomy themes with their routines under the celestial dome. Hinano establishes the team Galaxy Princess with her recruits. Her journey includes competing with the team in the "Pole Dance Japan Cup," facing the reigning champions, Aile d'Ange. Physically, she has shoulder-length light brown hair typically braided on the right side, gray or green eyes, pale skin, and an average build. Her attire frequently features a skirt and a single stocking. Her surname, Hoshikita (星北), merges the kanji for "star" and "north," forming an inverted variation of "North Star" (北極星) without its middle character—subtly tying her identity to celestial navigation and her grandmother's planetarium.
