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.

In order to oppose Tsukasa's army, she joins Tsukasa's group, serving as Senku's spy along with Taiju. After Tsukasa's defeat, she returns to the Kingdom of Science.

Yuzuriha is in charge of making clothes for the Kingdom of Science, along with reassembling damaged or destroyed petrified humans for revival.

Appearance
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 wore a standard high school uniform. After her depetrification, she wears a white cloth dress that's split 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.

After her second revival, her scars disappear. She soon adorns war paint in reflection of her stone markings during Tsukasa's revival.

Personality
Yuzuriha 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 is even willing to sacrifice herself when she is 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.

Like Taiju, she possesses a great amount of determination as well as faith, not truly believing Senku died and despite the clear evidence showcasing otherwise, eventually figures out a way to revive him along with Taiju.

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 won't abandon what she is 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 destroys 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 to be, at the very least, smarter than Taiju because when Senku claims to Nikki in an effort to get her to switch sides through the telephone that American forces are going to rescue them, while Taiju believes it, Yuzuriha is quick to understand the situation and that Senku is lying.

She loves fashion and becomes intense when crafting clothes.

Abilities and Skills
Master Tailoring: Yuzuriha has extraordinary sewing capabilities, as well as excellent handiwork. Senku had full faith in her skill, as he placed the task of re-assembling the smashed stone statues into her care. Indeed, with a form of primeval glue. She also makes fine leatherwork, one of which is used as the flag for the Kingdom of Science. Later, she is able to create high-quality clothes and opens Yuzuriha's Department Store after Senku and the gang manage to invent cloth.

She's been described as a "wild beast" when crafting, as she quickly and fiercely puts together whatever she's working on at astonishing speed.

Trivia

 * Yuzuriha's name is composed of "yuzuriha" (杠 lever) and her surname Ogawa is composed of "o" (小 little; small) and "gawa" (川 stream; river) to create Ogawa (Small River).
 * Yuzuriha shares a motif with Taiju and Senku in that her name contains "gawa" (川 stream; river) in her name, which correlates to the theme of "land, sea, and sky".
