Shiori Goshiki, 19, is the princess of the People of the Shooting Stars, descendants of microorganisms within meteorites. Fleeing an arranged marriage on her isolated island, she seeks love on Earth. Her lineage traces back to her grandmother merging with the meteorite's microbe, passing the princess role to Shiori's mother, Miyako Goshiki, and then to Shiori. This heritage manifests as a unique thorn on her lower back, central to her people's traditions. She possesses fair skin, light blue eyes with aqua-green nuances, and very long blonde hair falling below her waist. A single shoulder-length strand frames the right side of her face, accompanied by bangs across her forehead; she typically wears it loose or in a ponytail while working. Her oval face features delicate traits: thin arched eyebrows, a slender nose, and defined lips. Her slim figure curves gracefully, and she favors dark clothing—especially dark magenta and black—often choosing long dresses or layered outfits. Initially reserved due to her sheltered upbringing, Shiori is kind, gentle, and calm. She addresses mistakes with honest directness but flusters easily in romantic situations. Despite naivety about everyday life, she shows mental resilience and adaptability, quickly befriending others with her communication skills. Over time, her expressions shift from serene or blank to visibly animated, reflecting emotional growth. Admiring manga under the pen name Momotea, she became assistant to artist Ichiro Kuga. Having discovered manga only a year prior through her grandmother's collection, she honed exceptional artistic skills through self-study, becoming indispensable to Ichiro. A pivotal moment occurred when Ichiro mistook her thorn for a pen and pricked himself, activating a magical contract that binds them. This connection inflicts physical harm on Ichiro if they separate or if he hurts or offends her. Forced to cohabitate, they gradually develop genuine romantic feelings. Their relationship deepens as Shiori supports Ichiro's career, navigates daily life with him and his siblings, and confronts challenges from her family, particularly her strict mother Miyako. Overcoming parental objections and societal traditions, Shiori and Ichiro marry, making her Shiori Kuga. They later have a daughter, Ichika Kuga. Shiori also forms significant bonds, including admiration for mangaka Momoka Morikuni and friendships within Ichiro's circle. Shiori's journey encompasses self-discovery, emotional maturation, and integration into human society. Evolving from a sheltered princess bound by tradition, she becomes a self-assured individual choosing her own path, embracing love, building a family, and pursuing her artistic ambitions.
