Samari Ittan is a senior gardes pilot and squad leader aboard the generational ship Sidonia, commanding her own specialized unit. Her call number, 005, marks her as the vessel's fifth-highest-ranking gardes pilot, reflecting formidable combat skills and extensive experience honed through proficiency with the Kabizashi weapon in garde combat. She maintains a stern, disciplined demeanor during operations, exerting strict authority over subordinates while commanding respect off the battlefield. Often accompanied by at least two squadron members throughout Sidonia, she deeply values every pilot under her command. This concern drives decisive actions, such as orchestrating an unauthorized large-scale rescue mission for pilots Nagate Tanikaze and Shizuka Hoshijiro against orders, and fuels profound grief at combat losses. Her appearance features long black hair typically tied in a ponytail with two locks framing her face, brown eyes (depicted as black in the manga), and attractive features that draw frequent romantic advances from fellow pilots, though she remains professionally detached. She wears the standard garde pilot skin suit distinguished by purple streaks denoting defense squad affiliation. Her combat effectiveness extends beyond individual prowess to strategic team coordination, though complications during missions trigger frustration. She served as the original test pilot for the advanced Type-19 garde before its reassignment. Survival through high-risk engagements against threats like the Hawkmoth and Large Mass Union ship underscores her resilience and tactical acumen. She smoothly deflected Tsuruuchi's attempt to embrace her in a group photo with an elbow. While reportedly expressing interest in Tanikaze's abilities, she maintained personal boundaries, notably rejecting photosynthesis partnership proposals despite advances from others.
