Nosuri leads the Nosuri Thieves and is Ougi's sister. As a member of the Evenkuruga race, she possesses enhanced strength and agility. Her appearance features long red hair styled in odango buns, blue eyes, and a pale, slim figure with a noticeably curvy build. She typically wears a leotard and arm warmers, and wields a bow. Her personality is energetic, competitive, and brash, marked by a strong sense of honor and dramatic flair. Headstrong and stubborn, she is deeply devoted to her duties, though her short-sightedness and clumsiness often lead to comedic mishaps during missions. She enjoys gambling and drinking but despises losing. Despite being a thief, she adheres to a code of ethics, targeting only corrupt nobles and calling herself an "honorable thief." A notable quirk is her severe seasickness. Her background is shaped by her father, Genho, a disgraced former Eight Pillar General punished for misconduct during a Mikado mission. This drives her ambition to restore her family's honor and earn a position among the Eight Pillar Generals herself. Initially, she and Ougi worked as mercenaries under Ukon before being rescued by Haku's group and joining them. Her relationship with Haku evolves from initial hostility and awkward encounters to warmth after he shelters her and Ougi from imperial guards. While Haku impersonates Oshtor, they grow closer, leading to unacknowledged romantic feelings on her part, which she bashfully denies due to her Evenkuruga heritage. Her bond with Ougi is central, as he acts as her steadfast supporter and assistant. In broader conflicts, Nosuri fights with Haku's loyalist faction against Yamato's usurpers. Her combat role leverages Evenkuruga agility, specializing in archery. Though her plans often falter in execution, her idealism and loyalty remain unwavering.
