Yuzuriha Ogawa

Yuzuriha Ogawa (小川杠 Ogawa Yuzuriha) is the love interest of Taiju Oki and a friend of Senku Ishigami. She was depetrified in 5739 AD. Yuzuriha is a young woman with brown hair, brown eyes, and a slim build. She has two noticeable petrification scars, both in the shape of spirals, located on her shoulder and neck. Before her petrification, Yuzuriha wears a standard High School Uniform. After her depetrification, she wears a white cloth dress that's spit at her sides and matching cloth shoes. Noticeably, Yuzuriha wears a white hairband that's vaguely shaped like wrap-around headphones, both before and after her petrification. Following an encounter with Tsukasa, her long hair is cut to a shoulder-length bob. Yuzuhira is a kind individual who tries to aid her friends and strangers alike in whatever ways she can. She usually uses her extensive crafting skills to help Senku carry out his inventions or reassemble destroyed petrified humans.

Like Taiju, she is fiercely loyal to Senku. As childhood friends, she understands Senku's abilities and potential and was even willing to sacrifice herself when she was being used as a hostage by Tsukasa to allow Senku to escape. While not explicitly stated, she seems to return Taiju's feelings but is waiting for him to make his official confession. She seems quiet and while not overly shy, is usually reserved. She tends to get nervous in dangerous or unpredictable situations but knows to keep her mind at the task at hand. In chapter 73, Senku refers to her as someone who wouldn't abandon what she was doing to make her own moves and when given a task, puts 100% of her attention and motivation towards it.

She is rather patient, showing great skill in carefully gathering the stone fragments of the statues Tsukasa destroyed and painstakingly putting them back together in the hopes of fixing the statues and giving the people a chance at revival. She is also used to listening to Senku's lectures on science (at one point managing to endure a 5 hour lecture on science from him). She seems at the very least smarter than Taiju because when Senku claimed to Nikki in an effort to get her to switch sides, through the telephone, that American forces were going to rescue them while Taiju believed it Yuzuriha was quick to understand the situation and that Senku was lying. She loves fashion and becomes intense when crafting clothes. Yuzuhira has extraordinary sewing capabilities as well as excellent handiwork as she is seen re-assembling the smashed stone statues with a form of primeval glue. She also makes fine leatherwork, which is then used as the flag for the Kingdom of Science. Later, she was able to create high-quality clothes and opened Yuzuriha's Department Store after Senku and the gang manage to discover cloth.
