Yuzuriha Ogawa was a high school student petrified alongside all humanity by a mysterious green light. Moments before petrification, her classmate Taiju Oki prepared to confess his feelings to her. She remained conscious while petrified, aware of time passing until Taiju and Senku Ishigami revived her 3,700 years later using nitric acid-based revival fluid. Revived, she entered the conflict between Senku and Tsukasa Shishio. Tsukasa captured her as a hostage to force Senku to reveal the revival formula; she pleaded with Senku not to sacrifice himself for her safety, demonstrating loyalty to his cause. After Senku faked his death, she and Taiju infiltrated the Tsukasa Empire as spies under Senku’s orders. Her mission involved secretly collecting and reassembling shattered petrified humans destroyed by Tsukasa. Using exceptional crafting skills, she painstakingly glued fragments with primitive adhesives—a task requiring immense patience and precision that reflected her dedication to preserving life. Yuzuriha possessed advanced tailoring and crafting abilities, specializing in textiles like sewing, felting, spinning thread, and weaving. Her skills proved vital to the Kingdom of Science: she crafted its flag through leatherwork and later established a clothing store after cloth’s invention, serving revived modern humans and Ishigami Village inhabitants. Her passion for fashion drove intense focus during work, described as "wild beast"-like in speed and ferocity. She collaborated with Kaseki on projects such as a detailed Earth model, combining her soft-craft expertise with his hard-craft skills. She exhibited above-average intelligence, though not matching scientific geniuses like Senku. She consistently saw through deceptions, recognizing Senku and Gen Asagiri’s ruse to recruit Nikki Hanada during the Communications Arc and understanding Gen’s manipulation of villagers during farm work incentives. She endured Senku’s scientific lectures in youth, indicating capacity to absorb complex information. Her mental resilience emerged during a second global petrification event, where she consciously counted seconds for eight years until revival—mirroring Senku’s strategy to maintain awareness. After the Stone Wars, she became an official Kingdom of Science member. She joined the Treasure Island voyage aboard the Perseus, where Kirisame petrified her; she was later revived. She assisted in repairing petrified humans and helped expose the Petrification Kingdom’s true nature. Following a seven-year timeskip after the second petrification, she and Taiju resumed duties for the Kingdom of Science’s moon mission, marrying in the story’s finale. Physically, she had brown hair, brown eyes, and a slim build. Post-first revival, she bore spiral-shaped petrification scars on her shoulder and neck. After an encounter with Tsukasa, her long hair was cut into a shoulder-length bob. These scars vanished following her second revival, after which she adorned war paint mimicking her former stone markings. By the epilogue, her hair regrew to its original length. Her personality blended kindness, determination, and quiet resolve. She aided friends and strangers alike, channeling crafting skills to support Senku’s inventions and petrified humans’ restoration. She shared deep loyalty with Taiju toward Senku, rooted in childhood friendship. While her romantic feelings for Taiju were evident, she waited for him to formally confess. She maintained faith in dire situations, refusing to believe Senku died and later devising his revival method alongside Taiju.
