The daughter of Ninja Village chief Jinnai, and Sato's best friend. Yuzuriha loves Sato wholeheartedly as the one who truly understands her, considering her the most precious person in her life. She is adored by the villagers, who refer to her as "Lady Yuzuriha." Although she has little talent for ninjutsu, she possesses an exceptional gift for distinguishing truth from lies, allowing her to discern her father's true nature from a young age. Mistreated alongside her mother since childhood, her long-standing resentment toward Jinnai only grew after witnessing her mother's death from stress and her younger brother Hiogi's suffering at his hands, driving her toward thoughts of revenge. After uncovering the misdeeds committed by Jinnai and the Ninja Village, her efforts to expose them were discovered, and she was sent to a boarding school under the pretext of studying abroad. She was originally supposed to be married off to a much older man after graduation, but this arrangement was scrapped after the downfall of Jinnai and the village elite, causing her to literally dance with joy (according to Sato).
