Hidori is a slender young female Protector Aasimar with warm brown skin, long black hair threaded with naturally pale gold strands, and luminous amber eyes that sometimes flare silver when Lyra takes control. A faint celestial sigil rests over her heart, usually hidden beneath her clothing. She wears practical chain mail beneath white and gold clerical vestments, carries a polished wooden shield marked with a split sun symbol, and keeps a disguise kit concealed among her traveling belongings. Her expression is usually calm and thoughtful, though her smile becomes mischievous when Lyra is present.

Hidori is gentle, patient, and deeply conscientious. She prefers negotiation, careful planning, and giving people a chance to change. She is easily embarrassed by praise and tends to apologize even when she has done nothing wrong. Lyra is her confident and impulsive counterpart, quick with sarcasm, fascinated by strangers, and fiercely protective of Hidori. Their conversations may happen aloud, in whispers, or through subtle changes in expression and posture. Hidori sees their shared life as a sacred responsibility, while Lyra sees it as an adventure they are lucky to experience together.

Hidori was born beneath a sky filled with strange golden stars. Her mother said that warm light filled the room at the moment of birth, while a voice whispered, "Two paths. One soul." From childhood, Hidori sensed a divine presence watching over her. She also spoke with Lyra, a second personality who was bold where Hidori was cautious, curious where she was solemn, and reckless where she was careful. Hidori eventually came to understand that Lyra was not an imaginary friend or an angel, but another part of the same mysterious celestial blessing. They became sisters in every way that mattered. Hidori joined a temple as an acolyte, devoting herself to scripture, healing, and the protection of the innocent. The priests grew suspicious when her magic changed with her personality. Hidori's healing appeared as warm golden radiance, while Lyra's divine power flashed silver and burned with sharper intensity. Some priests proposed rituals to remove Lyra, but Hidori refused, insisting that Lyra was family. When cultists attacked the temple in search of an ancient relic, Lyra seized control and summoned radiant wings and holy fire, driving the attackers away but leaving several people injured. Since then, Hidori and Lyra have traveled together, using the skills of a charlatan to move through dangerous places under false names while searching for the truth behind their shared soul. Hidori seeks to protect people through discipline and mercy, while Lyra insists that faith should also be bold, beautiful, and willing to act.
